ABSTRACT
Uganda has experienced a high economic growth of over 8% p.a as a result of
liberalisation of the economy. This has positively impacted the construction industry which has
grown at an average rate of over 10% between 1995 and 2009. This high growth rate of the
construction industry has influenced the Growth National Product and directly provides
employment to many Ugandans and foreigners.
However, the construction industry has become the most hazardous industry in this
country and the world over by presenting more accidents, injuries, ill health and occupational
diseases than any other industry. Examples of the widely published common accidents include
collapsing of structures, cave-ins of excavations, falls from heights, dropping objects striking
workers, machine hazards, and many others.
This research revealed that these occupational accidents on construction sites emanate
from poor safety culture due to lack of awareness of safety requirements, inadequate site
management, supervision land inspection, insufficient soil investigation, use of incompetent
personnel, use of faulty designs, use of poor construction materials, non-compliance to safety
rules due to weakness in legislation and enforcement organs.
The occupation accidents, disease and ill health in the building construction industry can
be more effectively mitigated by matching the technological advancement in the industry with
re-engineering of occupational health and safety strategies and ideas; and by using proactive
approaches that focus on occupational health and safety comprehensive programmes other than
merely on giving employer directives that involve the provision of personal protective gears to
employees. Emphasis need to be put on dissemination of information on safety to the workers

and public through awareness campaigns, safety education and training in addition to provision
of adequate site management, supervision and inspections.

Introduction
This study focused on the pattern of occupational accidents at building construction sites
in Kampala District. The information in this dissertation is arranged in chapters.
Chapter one introduces the research topic, brings out the objectives of the research; and
the statement of the problem. Chapter two reviews the contributions of different scholars to the
research subject. Chapter three is concerned with methodology where by research strategy, data
analysis techniques; and criteria for the interpretation of results are elaborated in this chapter.
Chapter four is concerned with data presentation and analysis of empirical data,
interpretation of empirical data; and presentation of results and findings. Chapter five brings out
the implications and significance of the study. It elaborates implications for methodology and
data availability, implications of findings for the theory/policy/practices; and possible policy or
other suggestions and recommendations. Chapter six, outline the recommendations and
conclusions of the study.
Background of the Study
Since 1990, when Ugandan economy was liberalised, there has been greater development
in all sectors. The construction industry for the last thirteen years (1990 – 2003) had a growth
rate of an average of 5.7 percent per annum. From 1995/96, it has continued to grow at an
average rate of 8.8 percent per annum well almost at par with 2007/08 GDP annual growth rate
for Uganda of 8.9 percent, coming next to agriculture in the economy.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU

Investigations carried out by Department of Occupational Safety and Health (DOSH)
under Ministry of Gender, Labour and Social Development indicated that the construction
Industry is made up of small contractors, a number of medium sized contractors and a few big
contractors often foreign who also get into joint ventures or sub-contract a number of medium
and small sized contractors on the big projects they undertake. Seventy percent (70%) of all
construction is informal with many individual developers directly undertaking complex
construction projects employing mostly unskilled labour to including children who in many cases
are often ignorant, negligent, and careless. This results into numerous hazards hence causing
fatal and non-fatal accidents.
In Uganda, construction project management has in recent shown greater emphasis on
time and cost at the expense of safety of the people involved in the industry. Lack of adherence
to safety regulations and requirements has led to increased exposure of the workers and the
general public to risky situations including a high rate of accident occurrence on construction
sites.
Rampant accidents in the construction industry pose direct and indirect physical injury to
persons. Which include loss of wages, hardship due to reduced earning, human suffering and
sorrow that no amount of compensation or benefit can erase; and psychological/social traumas to
affected families. On the side of the project engineer/client, losses due to costs of medical
treatment, worker compensation, replacing damaged equipment, wasted working time, replacing
injured workers as well as negative publicity. The result of accidents is therefore, lost production
capacity of the injured persons, death and reduced work output for the organization. This retards
both house hold and national economic growth.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU

According to International Labour Organization (ILO) estimates (2008), 6,000 workers
die each day worldwide as a result of work related accidents or illness. Moreover, each year there
are an estimated 270,000,000 non-fatal work-related accidents as well as 160,000,000 new cases
of work-related diseases.
The total cost of such accidents and ill health have been estimated by ILO to be 4% of
global GDP (more than 1.25 trillion US dollars) or more than 20 times the global amount of
official development assistance. Construction, mining, manufacturing and agriculture rank
amongst the most hazardous occupations globally.
Construction industry has one of the largest potentials for increasing a country‟s Gross
National Product (GNP). Construction industry is increasingly becoming the most hazardous
industry in Uganda despite the fact that it has a vast potential for direct employment provision,
not only in the real building construction activities but also in the construction materials industry
that include bricks, blocks, aggregates, cement, steel, aluminium, timber, paint, pipes and
fittings, hardware, and several allied industries, construction equipment and transportation.
However, the construction industry in Uganda has presented the highest fatality rates in
the recent past years amongst all the industries as shown in table 1.1 below;

Total 05 11 09 14 21 34 22 116
(Source: OSH Dept. Ministry of Gender, Labour and Social Development)
Between 1997 and 2003, a total of 39 fatalities out of 116 which constitutes about 33.6%
were associated to construction. In the year 2003, a total of 236 accidents resulting in 22 deaths
were recorded in Kampala district and 34 and 21 deaths from 354 and 209 accidents were
reported in the previous years of 2002 and 2001 respectively as a result of occupational
accidents.
According to New Vision newspaper of Friday 28/08/2009, Works and Transport
Minister, was reported to have said that between 1997 and 2009. A total of 13 accidents occurred
at building construction sites, killing 97 and injuring 151 people. This information puts at fore
front construction industry as the most hazardous industry in Uganda.
Lives and large sums of invested money are lost in Uganda and the world over, as a result
of collapsing structures, falls from heights, fire outbreaks, caving in excavations, during
construction or maintenance activities or after occupation of the premises.
According to New Vision of Tuesday 22/09/2009, “the causes of construction related
accidents country wide have included inadequate design, use of unqualified personnel, sub-
standard materials, poor construction methods and workmanship. Failure of the builder to
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
18
interpret available engineering, architectural drawings and technical specifications has also
contributed to the problem.”

It is because of the increasing numbers of collapsing construction sites and fatality rates
(death rates) in Uganda that has prompted the researcher to carry out a study into Occupational
accidents at building construction sites taking Kampala district as a case study.
Problem Statement
Uganda has one of the fastest growing economies in the world with GDP of 8.9%
(2007/08) and construction industry is among the leading contributors in Uganda. Because of the
boom, many non professionals register companies and carryout construction works; and most of
these companies, employ non qualified and non registered employees. This has greatly
contributed to the increasing accidents in the construction industry.
Between 2002 and 2009 above, many building construction accidents took place killing
many people and injuring thousands of workers. Much as they look very high as they are, these
are still too low compared to reality, because, data is got from only reported accidents within or
around Kampala district. Very many construction site accidents occur daily and many are not
reported to the authorities due to illegal construction taking place in this country leading to
fatalities, disabilities, injuries, psychological torture, and loss of lots of invested funds and time.
Therefore, the purpose of this research was to carry out a study into occupational
accidents on building construction sites and to recommend mitigation measures. To find out if
the provisions in the Occupational Safety and Health Act 2006, are being complied with or
implemented on construction sites in Kampala Uganda. This study was to find out whether the
contractors/employers are concerned with workers‟ health and safety; and whether the workers
on the construction site are aware of their rights to a healthy and safe work place.

The findings will contribute to the development of appropriate guidelines for safe
construction practices for people engaged in the construction industry in order to
minimise accidents.
The research will recommend improvements to the Safety and Health regulations
currently in place.
The findings are expected to contribute knowledge to the future leadership, and as a
source of reference for further research.
Justification of the Study
The increasing numbers of accidents at the building construction sites which leads to
direct and indirect physical injuries to persons. These include loss of wages, hardship due to
reduced earnings, human suffering and sorrow that no amount of compensation or benefit which
can erase away psychological/social traumas to affected families. Also losses due to costs of
medical treatment, worker compensation, replacing damaged equipment, wasted working time,
replacing injured workers as well as negative publicity. All these have led to retardation of both
household and Ugandan national economic growth that the researcher decided to undertake this
research.

CHAPTER TWO
LITERATURE REVIEW
Introduction
In this context, analysis of existing literature from different writers/researchers who have
appreciated the topic of “Occupational health and safety” at work places were acknowledged. A
number of researches have been done by different people in various parts of the world in line of
safety and public health in work places in general. However, in this case only literature relating
to building construction sites was reviewed.
Overview
The complexity of the construction industry makes occupational ill health difficult to
assess not only in the developing countries but the world over. Construction comes high in the
comparative list of accident rates in many work places. The high number of accidents in
construction work is not caused entirely by the fact that the work often has to be done at great
heights or in deep pits or shafts. The vast majority of injuries are due to simple causes, similar to
those encountered in other industries like falling, stepping on objects, being struck or trapped by
objects, faulty handling of objects and incorrect use of hand tools. The difference between the
injuries occurring in construction work and those in other industries are mostly ones of degree
rather than type of injury.

Conceptual framework
Explanation of conceptual framework
Occupational accidents on building construction sites involve falls from heights, slips,
trips and fall from the same level, tool accidents, struck by material accidents, crane accidents,
scaffolding accidents and many others. Once not prevented from occurring can cause accidents
the building construction sites. Hence the building construction site cannot be free from the
accidents. But once they are prevented, no accidents will occur and the building construction site
will be safe.
The causes of accidents on the building construction sites are lack of supervision and
control on worker‟s adherence to wear safety wear, lack of appreciation after completion of task,
lack of safety equipments, lack of proper training; unsafe site conditions and many others. Once
prevention measures are not in place, occupational accidents on building construction site will
occur. Hence, accidents will occur on the building construction site and it will not be free from
accidents. But if they are taken care of, there will be no occupational accidents occurring and the
building construction site will be free from accidents
Prevention is better than cure, prevention of accidents and causes of accidents can be
done through adequate designs, quality control of materials, proper construction work

techniques, adequate supervision and others. Once occupational accidents and their causes are
prevented from occurring on the building construction site, the site will be free from accidents.
But if they are not controlled accidents will occur and building construction site will not be free
from accidents.
For a building construction site to be free from accidents there should be proper measures
on the site to prevent causation of occupational accidents from occurring.
Occupational accidents that occur on building construction sites
Phil Hughes and Ed Forrett (2008) pointed out the most common accidents that occur on
workers on building construction sites. These included slips, trips and falls on the same level, fall
from height, being struck by moving, falling or flying objects, and striking against fixed or
stationary objects.
The major forms of site accidents in the building construction industry are: structural
failures, machinery (involving construction plants) accidents, fall from heights, falling objects
(improperly staked materials or tools and equipments), excavation cave-in, equipment mishaps,
fires and electrocutions. P.P Dharwadker (1990), had this to say; ‘In U.K, statistics revealed that
more than 60% of fatal accidents in the construction industry occur due to persons falling from
heights or due to them being struck by falling objects from heights.’ He further stressed that; ‘the
accidents occurring because of structures failure and after construction, collapse of centring and
shuttering, failure of building scaffoldings, caving-in excavations and damage of fire are
indicators of utter lack of awareness of occupational safety in the industry.’
According to the African Newsletters on OHS (2001 and 2004), occupational health
hazards can be categorised as physical, chemical, biological and social hazards.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
27
Physical Hazards
These include:
Noise and vibration hazards which cause harmful effects to workers, including hearing
defects/loss (deafness), annoyance/irritability, psychological.
Welding hazard which include the presence of ultraviolet lights, gas leaks and metal
fumes released during the welding processes. These hazards are associated with fire and
explosions which result into burns from heated metal work pieces; electric shocks from
damaged cables and faulty circuits; photo-ophthalmia from electric arc flash; fume fever
from melting metals; and gassing accidents from toxic metal oxide fumes.
Musculoskeletal impairments resulting from cumulative trauma, chest pain, knee lesions
and low back pain which are due to lifting, lowering and carrying heavy loads and
aspects of work posture such as bending, twisting and reaching out of materials. These
can lead to permanent disability.
Excessive dust resulting from cutting, plainning and sanding operations in carpentry,
demolition operations, excavation operations and others.
Chemical Hazards
Some building materials such as cement, lime, paints, adhesives oils, solvents and many
others contain chemicals which are corrosive to the skin, cause skin irritation and allergies in the
event of direct contact and when inhaled they may lead to respiratory ailments such as bronchitis
asthma and rhinitis. Other health hazards due to exposure to chemicals may be dermatitis and
cancer.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
28
Biological Hazards
During site clearance operations, workers are exposed to risks of insect and snake bites
leading to illnesses and fatalities. Sometimes inhalation of pollen and fungal spores can cause
respiratory allergies. Furthermore, working in wet conditions increases the likelihood of fungal
infections of toes, fingers and nails unless the workers are provided with protective gears.
International Labour Organisation on Occupational Health and Safety in the construction
industry
Using some statistical data from USA, France, Spain and Argentina, it will be easy to see
the significant contribution of construction industry to employment creation (5.4% in the USA,
7.6% in France, 9.2% in Spain and 10.4% in Argentina). The construction industry has
traditionally been considered a hazardous occupation, due to the incidence of occupational
accidents and above all, of fatal injuries.
Another common feature is the high proportion of the work-related accidents of a
particular country that occurs in the construction sector (8% in the USA, 19% in France, 22% in
Spain and 14% in Argentine), which makes construction safety a compelling issue.
The statistical information also reveals that the likelihood of a construction worker suffering a
fatal injury at work is several times higher than that of an average worker. Therefore,
construction workers have a strong argument for demanding the national policies and
programmes on occupational safety and health but a high emphasis should be on the construction
industry.
Historically, occupational safety and health programmes in construction have been
focussed on the area of safety, that is, on the prevention of accidents. This is not surprising
because of the immediate visibility of the effects of accidents (injuries and material damages) as
compared to diseases whose consequences appear only after a period of time. The problem lies in
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
29
the fact that the health of workers may be affected many years after being exposed to a certain
agent or contaminant at the workplace. Thus, reliable statistical data on occupational disease,
especially in the case of a work force as mobile and sporadic as construction, are difficult to
obtain. (Alberto Lopez-Valcarcel, 2001)
Causes of building construction site accidents
Tutesigensi, A. and Reynolds. J.R (2008) investigated the causes of accidents on
construction sites; and their case study was the case of a large construction contractor in Great
Britain. The aim of the study was to identify the causes of accidents on company A‟s
construction sites; and to suggest how accidents on company A‟s construction sites can be
minimised. This was achieved using the following objectives:
Acquire information about incidences of injury, disease or dangerous occurrences.
Analyse the information acquired in order to identify the primary and secondary causes
of the incidences.
Analyse data derived from the acquired information in order to quantify the relative
importance of the primary and secondary causes.
Suggest strategies that can lead to reduction in incidences of injury, disease or dangerous
occurrences.
The researchers found out that the top three primary causes of accidents on contractor A‟s
sites are causality error, work methods and poor quality error while the top three secondary
causes are work methods, causality errors and site conditions.
T. Michael Toole (2002) conducted a survey on construction site safety roles. He identified
the root causes of construction accidents as lack of proper training, deficient enforcement of
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
30
safety, lack of safety equipments, unsafe methods or sequencing, unsafe site conditions, not
using provided safety equipment, poor attitude towards safety, and isolated freak accident.
Michael Armstrong (1979) said that; „building site diseases and accidents result from a
multiplicity of factors, but these have to be traced to their root causes, which are usually faults in
management system arising from poor leadership from the top; inadequate supervision;
insufficient attention to the inclusion of health and safety precautions into the system; an
unsystematic approach to the identification, analysis and elimination of hazards; and poor
education and training facilities.’
John Cameron Aspley (1955) said that; ‘....................accidents do not happen, they are
caused. They are caused because someone did something he should not have done or somebody
failed to do something he should have done. Carelessness, indifference and negligence are
responsible for one out of three accidents.’ He further argued that; „the work assignment should
match the mental and physical abilities of the worker and he/she should be selectively placed at
the job he/she can do best.’
Most of the accidents in building activities occur because of negligence, ignorance,
incompetence or complacency on the part of the workers, management or civic authorities.
(Gupta, 2000)
P. P. Dharwadker (1996), said that; ‘safety in high raised construction at the construction
stage and occupation and maintenance stages continue to be somewhat neglected in the
construction industry the world over......................most accidents in the construction industry are
due to negligence, ignorance, complacency or incompetence on the part of the workers,
management or civil authorities...............no sooner has the accident occurred than it is forgotten
till another accident take place.................Several reports bringing out the basic aspects and
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
31
deficiencies which come in the way of application for safety measures have been produced by the
inquiry of officers and the commission appointed for the purpose, but the follow-up action has
remained inadequate.’
He further stressed that; ‘practical applications of national code, which lays down
minimum provisions for building design to ensure the safety of the public with regard to
structural sufficiency, safety hazards and occupational health aspects, are followed more by
default rather than by rule and that basic deficiencies in legislation, loopholes in inspection
mechanisms and collusion at micro-level enables everybody concerned to go Scot free
irrespective of their apparent failure or even direct involvement.’
According to H. Lubega, B. M. Kigundu and D. Tindiwensi in their scholarly report
(Monitor 27-07-2006), said that; ‘accidents on building sites are mainly caused by inadequate
supervision, use of incompetent personnel, use of inappropriate construction techniques, use of
poor quality materials, lack of quality control, insufficient soil investigation, negligence of site
safety, weak foundations, site layout and lack of appreciation for use of professionals.’ They
further argued that; ‘other factors which lead to construction site accidents are negligence,
carelessness, and lack of commitment, ignorance, hunger, fatigue, inexperience, poor
communication/language barrier and inadequate visibility/inadequate lighting for night shifts.’
According to Eng. Dr. Francis Bazirake (2009), ‘among the accident causes are poor
design, inferior materials, poor workmanship and non observance of safety regulations; all of
which are avoidable’
Checking of the design by the local authorities is minimal as they lack capacity in
numbers, qualifications and experience. Site supervision is limited to checking whether the
developer has a building permit and is rarely done by a qualified engineer. Due to laxity in the
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
32
professions some engineers out of greed take on too much work which they cannot reasonably
execute. There is also disregard of specialisations so that any civil engineer thinks he/she can do
anything in his/her field of general education. There is also a problem of architects acting as lead
consultants whereby engineers are marginalised as they do not negotiate their fees with the client
and end up not dedicated to good practice. This approach is open to errors, which can
accumulate, such as lack of structural calculations and design, use of substandard materials, poor
workmanship and lack of qualified supervision on the construction site so that the resultant work
may be catastrophic.
Ransom (1987) argues that; ‘causes of failures/accidents in the construction industry are
either due to faulty design, poor execution, and use of poor construction materials or through
unexpected user requirements. There is a need to narrow the gap between the designers and the
constructors, and examine the design for build-ability.’
In the building inspection and construction in Kampala, Wakiso, Mpigi and other districts
of Uganda, reports by the Ministry of works and transport indicate that use of unapproved plans,
poor quality materials, and inadequate inspection by local authorities, architects, engineers and
safety officers are some of the contributory factors to the occurrence of accidents on building
sites.
According to William Mukasa, the rapid growth in the industry has brought about
increased threat to occupational safety and health and such as there have been a number of
injuries and fatal accidents in the recent past due to the following reasons:
Lack of clear policy by government on how the construction industry should operate
Out dated legislation, regulations have narrow scope and penalties are minimal
Limited number of safety and health inspectors
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
33
Inadequate resources for effective enforcement of legislation
Inadequate and incompetent supervision at the construction sites
Low attitude towards safety and health by clients
Lack of national standards for construction
Lack of awareness and understanding of safety and health regulations and generally
labour laws.
Lack of skilled workers or competent persons
Lack of Occupational Health and Safety information, training materials, courses and
programmes which the Ugandan construction industry could utilise.
Lack of thorough reporting of incidents and accidents
Weak professional institutions to monitor ethical conduct of their members
Weak contractors‟ association to benefit its memberships through training and other
health and safety services.
Inactive insurance industry
Use of inappropriate construction techniques and poor designs which do not take into
account safety and health
Workers‟ negligence, ignorance and carelessness (attitude and behaviour)
Mechanical failure of construction equipments, plants and machinery (often very old)
Unlevelled bidding ground due to design specifications not having considerations for
safety and health
Workers in poor health conditions and working under stress
Use of poor quality materials coupled with lack of quality control to ensure compliance
with standards or specifications
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
34
Weather and disaster
From the above literature, the causes and factors that lead to accidents on building sites
can be summarised as follows:
Accident causing factors
Human factors
These are categorised into psychological, physiological factors and unsafe acts factors.
Psychological Factors: these are related to the mental condition of the workers and they
include: stress, worry, mental tension, emotional attitude, impulsiveness, nervousness,
overconfidence, carelessness, fear, negligence and ignorance.
Physiological factors: these are related to the physical condition of the workers and they
include poor health, poor eye sight, old age, young age, intoxication, hunger, fatigue and
physical handicapped-ness.
Unsafe acts factors: these are risky acts which can be potential hazards leading to
accidents for example taking shortcuts, wanting to finish quickly, removing or not using
protective gears, not following approved preventive methods.
Technical factors
These include system breakdown, faults in equipments or machines, use of wrong
equipment.
Work environment factors
These include bad weather, repetitiveness and monotony of work, dirty working places.
Other causes of accidents
Inadequate site management and supervision, this leads to hazards not easily identified
and mitigated, the result may be repeated accidents.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
35
Defective or wrong equipment, here accidents may occur due to system breakdown,
faulty equipment being used, wrong equipments being used or use of equipment by an
inexperienced/incompetent person.
Failure to comply with the recommended safety provisions in design leads to potential
hazards.
Non-compliance to building standards and regulations, here unapproved or no plans are
used on many sites and even where approved plans exist they are not referred to on sites
besides lack of building specifications on site or failure to comply with them result in
accidents.
Inadequate inspection by the local authorities, structural engineers, architects and safety
inspectors. This is rarely done possibly due to poor facilitation, lack of commitment,
insufficient inspection staff, lack of knowledge about the location of the construction
sites, perception that the services of engineers and architects are expensive or poor
sensitisation of the need for supervision by engineers and architects.
Poor site layout may complicate or restrict movements on site and if materials are poorly
stacked they may fall on workers/visitors or obstruct them from moving vehicles leading
to collisions.
Use of poor quality materials that do not conform to standards/specifications and lack of
quality control lead to construction of weak structures prone to accidents.
Insufficient or lack of soil investigation before both designing and construction, which
might lead to poor design and weak/inappropriate foundations which consequently result
into the collapse of structures.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
36
Inappropriate construction techniques which are used on some sites especially in concrete
batching, mixing, transporting, placing and compaction may be due to incompetence,
ignorance, carelessness or inexperience of personnel.
Lack of or insufficient support and protection to excavations. Cave-ins of excavations
such as those of the Nakasero shopping arcade and Lumumba Avenue NSSF pension
tower were as a result of lack of insufficient support to sides of excavations respectively.
In addition, if excavations are not protected by fencing and warning signs, workers or
visitors can fall into them.
Use of incompetent, unqualified or unprofessional personnel. The contractors‟ and
clients‟ preference for cheap yet incompetent, unqualified and unprofessional personnel.
This has greatly exposed workers and the public to fatal and costly accidents. In addition,
some professionals execute work unprofessionally due to pressure from
clients/contractors who want high savings, lack of commitment or carelessness.
Prevention of accidents on the building construction site
Tutesigensi, A and Reynolds J. R (2008) came up with a proposal on reducing accidents as
follows:
Training which involves initial training – to train technical skills, health and safety
awareness and professional values. Advanced training – to master technical skills, deepen health
and safety knowledge and develop leadership skills. Periodic training should be done to value
human life, understand human behaviour and to communicate effectively.
Briefing which involves unpack tools/equipment – to ensure they are right, sufficient and
safe; prepare for work – rehearse processes, answer any question questions and check
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
37
understanding. Discuss risks – identify risks and highlight how the risk exposure can be
minimised.
Debriefing which involves packing up tools/equipment – check, clean and recharge them.
Reflect on what happened – identify risk events that occurred and identify the impact of the
events. Reflect on what did not happen – identify risk events that were avoided, why the risks
events were avoided and what needs to be done next time.
From the case study undertaken, the authors concluded that it is important that health and
safety is taken seriously at all levels in the construction industry as it affects all of us either
directly or indirectly. They also noted that action that focuses on effective training, briefing and
debriefing of workforce can increase awareness of health and safety issues among the workforce
and lead to reduction in accidents on construction sites.
T. Michael Toole (2002) conducted a survey on construction site safety roles. He noted
that there was no uniform agreement on the site safety responsibilities of design engineers,
general contractors, and sub contractors. His study suggested that specific site safety
responsibilities be assigned on future projects based on each group‟s ability to control the factors
needed to prevent the root causes of construction accidents.
His research came up with factors needed to prevent root causes of construction accidents
as:
Proper training should ensure that graduates have expertise in task; have expertise in
training requirements; able to interview, test or observe employee,; have access to prior
training records.
Safety officers should be able to monitor work on frequent basis; know safety
requirements for task; able to enforce safety.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
38
A supervisor on construction site should know what safety equipment is required for task;
able to provide and enforce use of equipment; know inspection and maintenance history
of equipment being used.
Supervisors should know standard methods and sequencing for task; able to observe
actual methods and sequencing; able to control methods and or sequencing.
Supervisors should know proper site conditions; able to observe actual site conditions;
able to control site conditions.
The supervisor on the building construction site should be able to observe employee
constantly; able to influence behaviour through evaluations.
The management of the building construction site should be able to interact with worker
frequently; able to influence attitude through evaluations.
Summary of the literature review
The author has learnt that to have a free accident environment on building construction
sites, training of all stakeholders of construction industry should be done. The previous
researchers on the study area do not emphasise the need to start training the young generation on
issues concerning health and safety since it is very hard to train an adult such a delicate topic.
Previous researchers have come up with so many ways of minimising accidents on
building construction sites but this has not stopped accidents from occurring on building
construction sites. The gap would be that they have failed to transfer this knowledge to the
concerned stakeholders.
The author has learned that management should always be in position to involve
employees on building construction site to participate in health and safety issues on building
construction sites. Evaluations should always be done and safety meetings should be attended by
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
39
all employees of the building construction sites. The previous researchers have failed to notice
that majority of workers on building construction sites are illiterate and do not encourage
employers to pass on safety and health messages on to the workers in the language they
understand best.

CHAPTER THREE
METHODOLOGY AND DATA COLLECTION
Introduction
This chapter details the methodology that was used during the study. It presents the study
design, target population, sample size, sample techniques, data sources, data collection
instruments, data analysis and interpretation, and limitations of the study.
The first step of the study was the identification of the research problem covering the
significance, objective and scope of the study followed by exploratory review of the available
literature. The information was gathered through books, journals and publications, reports,
internet search engines, interviews which took place through conversation and interaction with
building construction workers.
Exploratory research involving descriptive case - studies was used for the research study
because it is envisaged to be the best approach for obtaining suitable responses to questions
concerning the status of the subjects under study. Data was collected in order to answer the
established research questions.
Scope of the Study
The study was carried out in Uganda and the case study was in Kampala district. The data
was collected from the five divisions namely Nakawa, Makindye, Rubaga, Kawempe and
Kampala Central.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
41
The target subjects were the workers on the building construction sites and distributed
500 questionnaires to people working on construction sites located within Kampala district. The
researcher ensured that the questionnaires were approximately equally distributed among the 5
divisions making Kampala district. The research targeted to cover buildings that were still under
construction.
Questionnaires for the building construction site workers were later developed and then
distributed to respondents by hand; this was done between mid-July to end of August 2010.
Within that period, filled questionnaires were collected from the respondents and the researcher
had face to face interviews with the respondents as well. The data was then compiled, analysed,
discussed and conclusions made together with recommendations to improve the safety of
workers in the construction industry.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
42
Research Design
This is an applied research with a focus on the occupational accidents on building
construction sites and their mitigation measures in Kampala district, Uganda. A list of selected
building construction sites was identified and a random sample method used to select the
building construction site on which to carry out the study. The category of subjects/ownership
formed the centre of focus and included:
Government/public institutions – The study looked at government building projects
within the different ministries, corporate bodies or departments.
Private institutions – Here the focus was on private and corporate bodies.
Individual developers – This mainly looked at the construction of residential and
commercial building sites owned by individuals but have formal contracts with
contractors.
Sample Size and Sample Size determination
The sample space from which information was got ranged from site engineers, foremen,
Technicians, masons, and labours.
The current number of building construction sites was not available in the relevant
authorities within Kampala district like Kampala city council; and respective division
headquarters.
However, the sample size was determined using Kish Leslie‟s formula for sample size
determination. There were no available data of the current numbers of building construction
projects going on in Kampala district. So such basic values like prevalence and standard
deviations which are important in determining the sample size was not available. The expected
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
43
prevalence of the study problem was not available, therefore the prevalence of the problem was
assumed to be at 50%

construction sites to be filled by the respondents but 300 questionnaires only were recovered by
the end of the exercise.

44
Data Collection methods
The data collection methods included the following though was not limited to them
alone:
Questionnaire: The main interest behind these questions was to assess if indeed the expectations
are met or not as per the health and safety of workers on sites. About 500 questionnaires were
distributed to the participants who were anticipated to respond back upon each question.
Observation: By visiting the various sites and moving around, a number of working
environmental conditions of exposure of the workers were able to be seen.
Oral interviews: This was actually used were some people or participants were unable to
understand the language used on questionnaires.
Photography: Some photographs were taken, portraying the conditions prevailing on sites. These
show the physical state of the problems and give a very vivid elaboration in a pictorial form.
Study Population: The population comprised workers on the government or public building
construction sites, private building construction sites and individual developers who were by the
time of research were operating and under contracts.
Research Instrument
The instrument used in the data collection comprised:
An interview guideline, which was used to interview the different parties involved in the
identified projects.
Used structured questionnaires to obtain statistical data on specific technical information.
Observation of selected building construction sites that were under construction.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
45
Materials/Apparatus: Internet services, training manuals, hand outs, and computer programs
were used.
Research Procedure
The procedure used in the research involved the following:
Questionnaires were designed to collect information (data) of interest as per the topic.
Pre-testing or piloting scheme were done to ensure quality and validity of the
questionnaires distributed.
The questionnaire was then adjusted to suite the targeted category of respondents on the
building construction site.
Distribution of the questionnaires was done by the researcher and the research assistants
A follow-up of the questionnaires was done to collect and/or extract the raw data for
processing to enhance a basis of identification, conclusions and recommendations.
The raw data from the respondents or participants was then retrieved/collected and tallied
statistically.
Sorting of answered sheets was done in which those questionnaires not satisfactorily
attended were discarded, for their results were deemed insufficient and hence futile to
consider.
Processing of the raw data was done using selected statistical methods, which included
bar graphs/charts, link charts, pie charts and write-ups.

Ethical consideration and approval
Informed consent was requested from the respondents orally only after having informed
them what the study was all about and the objectives of the study. The researcher told them that
the study was solely for academic purpose and participation was voluntarily. To ensure the
confidentiality and anonymity of the respondents, when data was being collected, the
respondents were not required to write their names. Approval and mandate to carry out the study
was obtained from the Institute of Health Policy and Management of the International Health
Sciences University and from other relevant authorities.
Data processing
For the data obtained from the field, the researcher ensured that validity, reliability,
accuracy and correctness of the findings were achieved. It was tackled by using multiple
sources of evidence while collecting the data and to prove that all the different
methods lead to the same result or that they all support the same proposition.
Reliability was fostered through allowing the respondents give comments to the
results, reports and these comments were reviewed by observational methods on their
responses.
Data Analysis
Analysis involves working with data, organizing them, breaking them into manageable

learned; and finally deciding what to communicate to the others.

Limitations of the study/problems faced during the study
Denial to access sites
Some sites had strict rules of not allowing anybody who does not work on the building
construction site to access the site for information. The researcher then obliged to seek for other
sites who appreciated the need for researches by students.
Language barrier amongst the workers
This was rampant especially amidst the labourers who were illiterate. This made it
difficult for them to answer the questionnaires and therefore the researcher had to re-interpret.
Demand for pay
Meanwhile others were willing to give information, a set of individual site workers asked
to be paid to participate in answering the questionnaires. The respondents were made to know
that the research was academically oriented and not economically lucrative to the researcher.
Lack of cooperation from some site supervisors
Some supervisors would toss around when it is time to collect the questionnaires left
behind. This was a major time wasting factor because few sites would be covered in a long spell
of time. Some supervisors claimed they had no time to help in whatsoever way, not even
releasing a worker to reply to some questions from the researcher. Due to this, about 200
questionnaires out of the 500 distributed questionnaires were lost or considered abandoned (that
is to say, 40% of the total designed and distributed questionnaires). This reduced the range of
opinion taken.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
49
Less time to interact with the workers
In most occasions, the time of visiting the sites were working hours and so, it proved
cumbersome to have quite sufficient time with the participants to get the required information
from them. In some cases, they never trusted their supervisors to give them the time to speak to
the researcher. In this case, a mutual understanding had to be reached before any interaction was
initiated.
Financial constraints
Increase in fuel prices increased the transport fares and other subsequent prices of items
the researcher wanted to use. The researcher had to deplete his account aiming at finishing this
research.
Loss of questionnaires
Due to perhaps carelessness, some of the respondents misplaced their answered sheets
and this resulted into loss of data as well as financial loss on the researcher‟s side because of the
costs incurred in printing and photocopying more copies. Therefore more questionnaires had to
be redistributed by the researcher for this case.

CHAPTER FOUR
DATA PRESENTATION AND ANALYSIS
Introduction
In this chapter presentation, analysis of data, interpretation of empirical data, presentation
of results and findings of data collected from the field (primary data) have been elaborated. The
aim of the research was to study the pattern of occupational accidents at building construction
sites in Kampala district. The study focussed on the five divisions making Kampala district
namely Nakawa, Makindye, Kawempe, Rubaga and Central. About 500 questionnaires were
distributed but only 300 were recovered.
The findings are presented in line with the objectives of the research study and are
intended to give answers to the research questions which were formulated in relation to the
study. The lucidity of the findings has been demonstrated with statistical information backed by
the obtained data from the field.
Part 1: Worker’s Personal Data
The first part of the questionnaire was general information about the worker on the
building construction site. This included sex, age, job title, education, years of experience,
income per day, health history, and area where the respondent lives.

51
Sex
Gender is very important when it comes to the construction industry. It is believed that
women are more careful when it comes to safe guarding their lives and that of the others.
Analysis
Upon analysing the results obtained, a revelation of the percentage of men and women
working on the building construction sites within Kampala is as shown in the pie chart, figure
4.1.
Figure 4. 1: Gender of respondents working on building construction site (source: primary data)
Interpretation of the results
From figure 4.1, it can be seen clearly that of all the number of people working on the
construction site, 211 respondents (70%) are men and 16 respondents (7%) are women. 73
respondents (24%) did not answer this question. This shows the gender imbalance that exists
within the construction industry. Men believe and have persuaded the women to believe that
working on a building construction site is the work of men only which is not true. But the truth is
that women are more careful when it comes to safe guarding themselves and others against
accidents.

52
Age
Age is very important when it comes at executing work on the construction sites, as the
younger or older someone is the more likely to cause accidents.
Analysis
After analysing the results obtained, a revelation of the age of the respondents are
revealed in the bar chart, figure 4.2
Figure 4. 2: Age group of the respondents (Source: Primary data)
Interpretation of the results
From figure 4.2, it can be seen that the ages of respondents working on the building
construction site are: 4 respondents (1.3%) are below 18 years; 111 respondents (37.0%) are
between age 18 years to 30 years, 89 respondents (29.7%) are between 30 years to 40 years; 12
respondents (4%) are between age 40 years to 50 years; 84 respondents (28.0%) did not declare
their age.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
53
Job title
Job title helps in putting the building construction site in order as labourers will know
who is who on a site. When it comes to the safety on the construction site, someone must give
orders to the workers to be followed.
Analysis
After analysing results obtained, a revelation of the job titles of the respondents on the
building construction site are given in the bar chart, figure 4.3.
Figure 4. 3: Job titles of the respondents (Source: primary data)

55
are of higher diploma level, 20 respondents (6.7%) are of degree level, and 6 respondents (2%)
are of master level. 7 respondents (2.3%) did not respond to this question.
Years of Experience
In one way or the other, the numbers of years a labourer have spent on the building
construction site are attached to the safety on the building construction site. The more the
experience of the workers, the less error are expected to made, hence the safer the work.

CHAPTER FIVE
DISCUSSION OF FINDINGS
Introduction
To understand and identify the causes leading to occupational building construction site
accidents, presentation, analysis, and interpretation of results were done in chapter 4.
Part 1: Respondents’ personal data
The first part was general information about the respondents working on the building
construction site. Information included sex, age, job title, education, years of experience, income
per day, health history, and area where the respondents live. These are explained below:
Sex
Gender balance is very important when it comes to the construction industry. With 211
(70%) male and 16 (6%) female working on the building construction sites and 73 respondents
(24%) did not answer this question. It indicates that there is still a very big gap in the recruitment
of female workers on the building construction sites.
Women have been to believe that most of the work on the building construction sites is
supposed to be done by the men. Yet women are believed to be very careful when it comes to
safety issues. Women‟s involvement in the building construction activities will reduce the
rampant accidents occurring on the building construction sites these days. There should also be a
policy which directs employers on a certain minimum percentage of women employees an
employer should have on a building construction site.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
79
Age and years of experience
This is very important when it comes to the building construction industry. The study has
revealed that the majority of the respondents 111(37%) and 89 (29.7%) are of age 18 – 30 years
and 30 – 40 years respectively. Also, 55 (37%) of the respondents have less than 5 years of
experience. This indicates that the construction industry is dominated by younger people and less
experienced workers, which may contribute greatly to the causation of accidents on the building
construction sites within Kampala district.
It should also be noted with concern of 4 (1.3%) of the respondents who are minors
(below 18 years). This is a violation of children‟s rights whereby, children are not supposed to be
employed on the building construction sites. But with the high rate of drop-outs from schools,
increasing poverty rates and high moral decay among children and adults in Uganda; many
children resort to work on the building construction sites in search for survival. The children
involved in the execution of heavy tasks on the building construction sites have greatly increased
occupational accidents on the building construction sites in Kampala district and Uganda at
large.
The authorities should put up policies which make sure that certain activities on the
building construction sites are performed by people with certain experience and age. As it is for
district engineers whom are required to have a requirement of nine years and should be
registered with the Uganda Institute of Professional Engineers. Also law concerning child labour
should be enforced by all stakeholders.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
80
Job title
Job title helps in putting the building construction site in order as labourers will know
who is who on the building construction site. When it comes to the safety at the building
construction site, someone must give orders to the workers to be followed. The research revealed
that only a few top personnel are always on the building construction sites. For example, only 14
(4.7%) figure 4.3, were site engineers that means that people with key positions who must give
orders on the building construction sites, may be handling more than one sites at a time which
may lead to the labourers at the lower ranks to neglect safety regulations. This may be one of the
major causation of accidents on the building construction sites.
The project specifications should stipulate on the presence of people concerned with
safety and construction works always to be present on the building construction sites; and the
authorities should always ensures that these people are available on the building construction
sites always.
Education background
Uganda is still faced with high illiteracy levels and many people who stopped in primary
and secondary schools. This affects the workers‟ ability to read and interpret the safety
guidelines which may lead to non compliance of these guidelines, hence causing of accidents on
the building construction sites. The study has revealed that of the respondents at the building
construction sites, 6 (2.0%) are illiterate, 56 (18.7%) are of primary level and 73 (24.3%) are of
secondary level, figure 4.4. This is quite a bigger number where by the majority of these people
cannot read or interpret safety rules and regulations, and other documents which are in line with
educating about safety issues.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
81
Site managements should always be in position to translate these documents into the
languages the workers understands best, or they should be in position to hold regular site
meetings to explain these documents to all workers.
Income per day
An income of a worker can be a motivating factor or a de-motivating factor which may
lead to the good or poor performance of the worker. Of all the respondents in this study, a bigger
number of respondents 111 (37%) earn between 5000/= to 10,000/= and 3 (1%) earn less than
5,000/=.
With the increasing standard of living within Kampala city and its suburbs, this money is
very little for someone to survive on it with their families. This may lead to the workers being
stressed while working as is thinking of where to get extra money to supplement his/her pay.
This kind of condition may lead to the worker making errors as executing his/her job hence
causing accidents on the building construction sites. Others resort to stealing of construction
materials or buying substandard construction materials such that they get more money to survive.
This has greatly contributed to the increasing collapse of structures under construction.
The government should fix a minimum wage for the people working on the building
construction sites and should be revised always as the standard of living changes.
Health history
When a worker is having a health problem, is more likely to cause accident than the one
who does not have. According to the research, 21 (7%) of the respondents have health problems.
Of those with health problems, 4 (19%) have diabetes, 1 (4.8%) have high blood pressure, 4
(19%) have heart problems, and 12 (57.1%) have other diseases. When these people are being
given jobs to work on the building construction sites, their health records are not revealed or
asked. The employer may assign work to a worker with a health problem and because the worker
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
82
does not want to lose the job, tries on the work. In such situations the worker may fail during the
operation and end up causing an accident which may endanger the healthier co-workers.
The government should put up policies which demands to keep health record of all
workers on the building construction sites. The employer should also assign workers with tasks
according to their health status.
Place where respondents reside
The distance travelled by the worker from where he/she reside to the work place is most
likely to affect the performance of the worker on the building construction site. The research
conducted revealed that a bigger majority of the workers reside outside Kampala city 76 (25.3%)
figure 4.9, yet most of the construction work is carried out within the central division 78 (26%)
figure 4.10.
This longer distance the worker travels can make him/her tired and when coupled with
the traffic jam it can make the worker get late to the worker place. The employer may abuse, or
make the worker not to work that day, or the worker may be forced to work when he/she is tired.
All these affect the performance of the worker which may lead to the worker making errors while
working hence causing accidents.
The employer should always try to employ workers within the locality of the site, as this
will solve the problem of coming late to work and making the employees get tired in the morning
hours. Also the workers should always be encouraged to come earlier than their start of working
so that they get on time and have enough rest before they start executing their tasks.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
83
Part 2: Accidents and Site conditions
Division of Kampala, where the site is located
Most of the building construction sites are located within the central division 78 (31.1%)
figure 4.10. This may have an effect on workers as they execute their tasks. Kampala district
especially the central division is congested and so many activities take place which distract the
attention of the workers leading them to make mistakes on the building construction sites, hence
causing accidents.
Still most of the lands within the Kampala district are located in water logged places like
swamps which makes it difficult to construct within such areas if necessary measures are not
taken. This might lead to the collapse of soils and structures under construction.
The government should ensure that all necessary precautions are taken before allowing
developers to start executing their projects on the intended land. The employer should always put
up hoardings which are tall enough to obstruct workers from activities taking place outside their
buildings.
Ownership of the building construction site
Most of the owners of the building construction sites are private institutions 116 (38.7%)
and individuals 44 (14.7%) figure 4.11. The private institutions and individuals have a will to do
whatever they feel like doing; especially they encourage much selective bidding. This leads to
the use of incompetent workers. They have a tendency of omitting certain activities during the
construction process which are part of the contract documents in the name saving money. For
example carrying out geo-technical investigations and testing of building materials may be
ignored yet these have contributed a lot to the increasing occurrence of accidents within Kampala
district and the country at large.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
84
There should be a policy in place which forces all developers to use professionals and
carry out necessary tests before the work commences and also during the process of executing
work.
Types of accidents ever occurred on the building construction site
The research revealed that many accidents occur on the building construction sites. Much
as they are not recorded by the site officials, they endanger workers and in most cases they can
even cause death in the long run.
The most five types of accidents from figure 4.12, which ever occurred on the building
construction sites the researcher visited are as follows:
134 (29.5%) struck by materials accidents were attributed by poor stacking of building
materials on the building construction sites and non availability of walk ways on the
building construction sites. This type of accident occurs on almost all building
construction sites and a daily basis.
110 (24.2%) tool accidents, is another common accident that frequently occurring on the
building construction sites. Tools are always left unattended to on the building
construction sites and in many cases, certain tools are not serviced and some parts are
stolen, which may lead to their failure during operations hence leading to cause of
accidents. It is suggested that tools should always be inspected before use for their
suitability for the proposed work. It was also noted that nails and sharp metals are always
left all over the building construction sites which in turn harm workers on sites hence
causing accidents.
52 (11.5%) falling from ladder accidents is another type of common accidents that occur
on building construction sites. This is attributed by the use of weak ladders which lead to
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
85
their breakage. In most cases some workers do not use safety belts while on ladders such
that in case of accidents, they can be held by the safety belts.
47 (10.4%) falling objects from height accidents. Falling objects like timber pieces in
case of roofing, nails, hammers, dust, bricks, concrete, blocks and iron sheets can cause
accidents if the worker on whom these objects have fallen on is not properly protected
with the safety gears like helmet. Such objects should be put in one place where they
cannot fall, or they should warn workers not to pass under areas where likely falling
objects is to occur. Also platforms should always be erected such that in case of objects
fall, they can be held by these platforms.
33 (7.3%) falling from height accident is the fifth accident that is most frequently
occurring on the building construction site. This is attributed by the workers not using
safety belts while at raised heights such that in case of failure of the platform or ladders,
they can be held by the safety belts. At times, the platforms are slippery and others are
weak to support the users and the construction materials.
Apart from the above accidents, there are many other accidents which occur on the building
construction sites like contact with electricity, crane accidents, gas explosion, failure of lift
device, exposure to hazardous material, trench accidents, fall from roof opening, pit accidents,
slip/trip fall same level, scaffolding accidents, natural causes accidents, machinery vehicle
accidents to mention but a few.
The management of these building construction sites should always be vigilant such that
likely occurrence of accidents can be detected earlier so that mitigation measures are put in
place.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
86
Periods when accidents occurred
The research revealed that most of the accidents that occur on building construction sites
usually occur between 10:00am – 1:00pm 70 (23.3%) and between 4:00pm – 5:00pm 80 (26.7%)
figure 4.13. This is attributed to inexperienced labourers, together with employers putting a lot of
pressure on the employees to do a lot of work within a short period of time. This makes the
workers not concentrate on their jobs hence causing accidents.
The study also put forward that the bigger percentage of accidents occur during overtime
hours (5:00pm – 7:00pm) 90 (30%). Most of the time overtime is taken by workers who have
been toiling all day long and their bodies are tired. But because their pay is little as seen in table
4.6, they tend to take on over time such that they can earn more extra money to meet their
demands. This can lead to these workers‟ poor performance because of fatigue, hence leading to
an accident in the long run.
There should be a policy which stipulates the minimum number of worker a person
should work on a daily basis like as it is in most of developed countries.
Weather conditions during when accidents occurred
The research revealed that most of the accidents usually occur during rainy periods 57
(19%) and windy periods 19 (6.3%) figure 4.14. On most building construction sites, work does
not stop during rainy periods which make the surface of the site slippery and workers lose
concentration hence leading to causation of accidents. For the case of windy periods, stronger
winds can cause building materials to fall if placed on raised buildings, causing accidents on
building construction sites.
There should be a policy which stipulates on how to carry out activities during such
unfavourable conditions.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
87
Month in which accidents occurred on the building construction site
The study revealed that most of the accidents on building construction sites occurred
mostly in the month of October – December 63 (21%) and April – June 47 (15.7%) figure 4.15.
Accidents which occur mostly between April to June are attributed to hurry of completing of
projects before the end of the financial year. The employers make the workers to perform tasks
hurriedly and such situations workers forget to take safety precaution hence causing accidents.
For the case of the month between October – December, employers and employees want
to complete as many projects as possible such that they get money for the Christmas festivals.
This makes them work hurriedly and in the process this can lead to occurrence of accidents on
building construction sites.
Whether contractors have insurance policies towards the workers
Majority of the respondents said no insurance policies towards them 108 (36%), while 98
(33%) said that they do not know whether the contractor has insurance policy or not for them;
and the rest 78 (26%) of the respondents said that the employers have insurance policies for
them. It was noted with concern that a bigger percentage of the contractors do not insure their
workers which makes it difficult the worker to be compensated in case of an accident.
The government should come up with a policy which ensures that all workers on building
construction sites are insured.
Welfare facilities and Safety gears that exist on building construction sites
The research revealed that most of the building construction sites mind of protecting the
bodies of the workers like providing them gumboots 133, overall 128, overcoats 108 and helmets
103 from figure 4.17. But the employers neglect other equally important welfare facilities and
safety gears like fire extinguishers, first aid rooms, first aid personnel, drinking water, meal/rest
room, safety regulations, to mention but a few.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
88
All these should be provided and the local authorities should make sure that the project
has such facilities before the commencement of the project.
Part 3: Factors attributed to construction accidents
The aim of this part is to carefully examine and focus on the root causes of occupational
accidents that occur on the building construction sites in order to improve safety performance in
the construction industry. It identifies the major causes surrounding occupational building
construction accidents. Factors that can be attributed to occupational building construction
accidents were collected and identified through questionnaires given to workers on the building
construction sites within Kampala city. Then a total of 30 causes of accidents were categorised in
the three groups: management factors, human factors and the project factors.

Top 11 out of 30 factors likely to cause occupational accidents on building construction site
in Kampala
Table 5.1 shows the relative importance ranks and percentages of the 30 occupational
accidents‟ factors as postulated by the workers on the building construction sites in Kampala
city. The top 11 factors attributed to occupational accidents were mainly management – related
with five factors in the management group, four factors related to workers and two factors related
to nature of job. These top 11 factors are as follows:
1. Physical fatigue can cause occupational building construction accidents, 138.5 (6.5%) -
work related factor.
2. The management is pushing work regardless of labourer‟s ability, 137.5 (6.4%) -
management related factor.
3. Lack of appreciation after completion of task, 123.25 (5.8%) – management related
factor.
4. Not enough rest time during the task, 119.25 (5.6%) – job related factor.
5. Lack of supervision and control on worker‟s adherence to wear safety wear, 98.25 (4.6%)
- management related factor.

6. Workers do not have enough sleeping hours, 89.75 (4.2%) - work related factor.
7. Workers take overtime, 88.25 (4.1%) - work related factor.
8. No training program for the worker to implement the job 77.5 (3.6%) - management
related factor.
9. No written/known procedure for the assigned job is available, 75 (3.5%) - management
related factor.
10. Extreme weather conditions contribute to accidents, 74.25 (3.5%) - job related factor.
11. Work is performed while rushing, 74.25 (3.5%) - work related factor.
Detailed discussion of the results on the three different groups of occupational building
construction accidents
The following is a discussion of the results on each of the three different groups of
occupational building construction accidents as deduced from table 5.1:
Factors attributed to the management
This group of accidents‟ factors were ranked high by the respondents. It had five of the top
11 factors causing occupational building construction accidents. The management is pushing
work regardless of labourer‟s ability was considered the top cause of accidents in the group; and
it ranked second over the 30 factors. Lack of appreciation after completion of task; lack of
supervision and control on worker‟s adherence to wear safety items; no training program for the
worker to implement the job; and no written/known procedure for the assigned job is available,
were among the five very important causes of occupational building construction accidents.
It should also be noted with concern that the respondents also rated other causes of
occupational building construction accidents like appropriate personal safety procedure not
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
92
specified; correct tools are not used for the specific tasks; safety regulations are not followed; no
safety engineer at the site; and no or lack of weekly safety meetings.
It is evident that the workers are calling for the contractors to fulfil their duties by providing
safety instructions and training programs as necessary steps to ensure safety at the site. These
acts or omissions by the employers affect the workers‟ performance. To satisfy the general duty
of safety training, employers in the construction industry should find it necessary to provide
training at several levels from a basic introduction to safety for everyone on their building
construction sites in order to satisfy training courses for managerial staff and other staff
members. Safety should form part of all training for construction activities not only at building
construction sites but also in schools, homes, universities and other places.
Furthermore, safety meetings should be used as a vehicle to review the effectiveness of the
project safety efforts; to resolve current health and safety problems; to provide a forum for
planning safe construction activities; to plan ahead for new or change operations; and to update
the accident prevention program. Documents and meetings on safety at building construction
sites should always be translated such that every worker understands the safety issues.
The management should always value the workers and stop pushing them to do activities
even if these workers are not capable of handling such activities. The management should also
motivate workers by appreciating them whenever a task is complete. This will show a sign of
belongingness on the side of workers and hence improve their performance while on their
respective duties.
Building construction sites with more than 12 workers should be provided with a permanent
safety worker. The management should also ensure that all safety gears required by the workers
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
93
while executing their work are provided; and make sure that all workers are protected all the time
while on the building construction sites.
Worker related factors
This group was ranked second by the respondents. Four factors were among the top 11
accident causing factors. Out of the 30 accidents causing factors, the top most came from this
group which is physical fatigue can cause accidents. Others were workers take overtime, workers
do not have enough sleeping hours, and work is performed while rushing.
These factors rated by the respondents have really unearthed the true picture of what is
happening on the building construction sites within Kampala district. Due to the fact that the
construction industry is dominated by mainly youth about 38% less than 30 years as revealed
earlier in this study; and about 38% earn as little as less than 10,000/=. Workers on the building
construction sites are forced to take on overtime in search of more money which brings about
fatigue in their bodies. It should also be noted that these workers 97% reside outside central
division, yet most of building construction sites 26% are located within central division. This
makes these workers to travel longer distances and endure the rampant jam within the city centre
and by the time they reach the place work they are tired. Others, majority being youth go to
discotheques and bars to enjoy themselves, go to bed late yet wake up very early hence getting
little sleep. When all these factors are logically combined, they give a clear picture on the likely
causes of occupational accidents on building construction sites.
The respondents also rated some of the other likely causes of accidents on the building
construction sites like: some workers are suffering from health problems; workers are forced to
work even if they are not in an acceptable conditions; some workers are suffering from the
mental fatigue on the job; accidents occur due to misjudgement from the workers; workers have
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
94
no satisfaction with the nature of the job; workers are over confident; lack of knowledge by
workers on wearing personal safety items; and workers do not wear personal protection items.
Basing on all these factors the respondents raised, it calls for some guidance to be given
to workers on how to safe guard themselves and be trained on issues pertaining safety. Building
construction sites should have counsellors in addition to the safety officers to handle additional
problems of the workers which need their services.
Project related factors
This group was rated last but not least with two factors out of the top 11 factors that are
likely to cause accidents on the building construction sites. The respondents raised one of the
most important factors which came fourth among the top eleven factors which is: not enough rest
time is given to workers during the task. This can be seen by the fewer rest rooms 2.7% which
exist on the building construction sites. In Kampala district, workers are supposed to start at
8:00am and end at 6:00pm on most the construction sites with an allowance of one hour for
lunch of which in most cases lunch is not provided for by the employers. This is not enough time
for resting and the employers should always be in position to provide more time of rest at least
two to three hours during the day.
Extreme weather conditions contribute to accident was also among the most eleven
factors that contribute to the occurrence of accidents. As seen earlier, respondents said that 57%
of the accidents occurred during rainy periods and 19% occurred during windy periods. This
calls for management to always put on hold work whenever it is raining or there is too much
wind such that workers do not make mistakes during such extreme weather conditions.
These results are expressed by the workers on the building construction sites, and the
workers attributed the causes of accidents on the management of the projects and on the workers
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
95
themselves. This calls for all stakeholders in the building construction industry to do their part on
issues concerning safety; and the local authority should always monitor to see that safety and
health regulations are adhered to by all stakeholders on the building construction sites.
Possible policies or other suggestions
The Town and Country Planning Act – 1951
This act consolidates the provisions for the orderly and progressive development of land,
towns and other areas whether urban or rural
The occupational Safety and Health Act – 2006
This Act consolidates, harmonises, and updates the law relating to Occupational safety
and health; to repeal the Factories Act, Cap 220 and to provide for connected matters.
The Public Health Act – 1935
This Act consolidates the law regarding the preservation of public health.
According to Carol Carysforth, and Maureen Rawlinson, 1994, the following safety and
health regulations should be followed as stipulated below:
The Health and Safety at work Act 1974
Applies to all work premises, any one on the premises is covered by and has
responsibilities under the Act; whether employees, supervisors, directors, or visitors.
Requires all employers to as far as far as reasonably practicable ensure the health, safety
and welfare at work of their employees. This particularly relates to aspects such as: safe
working environment; well maintained safe equipment; provision of protective gears;
availability of information on safety; and appropriate training and supervision.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
96
Requires all employees to take reasonable care of their own health and safety and that of
others who may be affected by their activities; and cooperate with the employer and
anyone acting on his/her behalf to meet health and safety requirements.
Work – Place (Health, Safety and Welfare) Regulations 1992
Employers and others in control of work places are required to comply with a set of
requirements covering:
Safety which should include safely constructed doors, gates and escalators; and
safeguards to prevent people or objects falling from a height.
Facilities like sufficient toilets and washing facilities; adequate supply of portable water;
suitable accommodation for clothing; and rest areas including provision for pregnant
women or nursing mothers.
Safety Equipments
Not all safety equipments relate purely to work environment, the personal protective
equipments at work place requires that every employer should ensure that suitable personal
protective gears are provided to the workers who may be exposed to risky conditions while at
work except that risk has been adequately controlled by other means which are equally or more
effective. The four main types of protective equipments are:
Head protective gears such as industrial safety helmets, scalp protectors, caps, hairnets
and others.
Eye protective gears such as safety spectacles, eye shields, safety goggles, face shields
and others.
Foot protective gears such as safety boots or shoes with reinforced toe caps, slip-resistant
soles, foundry boots which are heat resistant, wellington boots for protection against
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
97
water, anti-static foot wear to prevent build up of static electricity and to give some
protection against electric shock and others.
Hand protective gears such as gloves designed to protect from cuts and abrasions,
extreme temperatures, skin irritation and dermatitis, contact with toxic or corrosive
liquids. In some cases protective clothing for body is also necessary like overalls
overcoats or aprons to protect against chemicals and other hazardous substances.
Accident monitoring
The records of accidents should always be examined regularly to:
Compare accident rates in the organisation with national statistics.
Identify areas of particular concern.
Identify improvements or deterioration in standards
Identify any area of change which may affect statistics like the introduction of a new
production process.
Check that any recommendations have been taken
Attending to an accident
All persons who are first to reach the scene of an accident, should examine themselves whether
they are qualified as first aiders or not. Whatever the status, it is always important to ensure that
nothing is moved or disturbed so that judgement of anyone who is involved in investigating why
the accident occurred is not affected.

CHAPTER SIX
RECOMMENDATIONS AND CONCLUSION
Conclusion
Building construction sites can be considered as the most dangerous types of working
environments. Many publications conclude that construction has more accidents of greater
severity than any other industrial sector and is responsible for a significant proportion of
industrial safety and health problems.
The Ugandan construction industry is no exception and like many other countries,
Uganda has a poor safety record. With an obsolete factories act in place, the Ugandan
Government has made no concerted effort to improve safety performance in the construction
industry. The recent construction disasters have awakened government to hasten the process of
updating the factories act and to put mechanism in place to ensure compliance.
While it may be urged that construction contractors have a moral, economic and legal
commitment to ensure that working conditions on site are healthy and safer; the responsibility for
safety must commence upstream of the construction phase of a project. Previous writers concur
that improvements in the performance of safety could be sustained if at design and tender stage
design philosophy and any matters pertaining to safety and health are brought to the attention of
the contractor. The aim of the research was to study the pattern of occupational accidents at
building construction sites in Kampala district.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
99
Objective 1: The research established the common occupational accidents that occur on the
building construction sites in Kampala district as:
1. Struck by materials accidents 134 (29.5%).
2. Tool accidents 110 (24.2%).
3. Fall from ladder accidents 52 (11.5%).
4. Falling objects from height accidents 47 (10.4%).
5. Fall from height accidents 33 (7.3%).
6. Exposure to hazardous materials accidents 28 (6.2%)
Objective 2: The research revealed most 10 factors that are likely to cause occupational
accidents on the building construction sites in Kampala districts as:
1. Physical fatigue can cause occupational building construction accidents, 138.5 (6.5%).
2. The management is pushing work regardless of labourer‟s ability, 137.5 (6.4%).
3. Lack of appreciation after completion of task, 123.25 (5.8%).
4. Not enough rest time during the task, 119.25 (5.6%).
5. Lack of supervision and control on worker‟s adherence to wear safety wear, 98.25
(4.6%).
6. Workers do not have enough sleeping hours, 89.75 (4.2%).
7. Workers take overtime, 88.25 (4.1%).
8. No training program for the worker to implement the job 77.5 (3.6%).
9. No written/known procedure for the assigned job is available, 75 (3.5%).
10. Work is performed while rushing, 74.25 (3.5%).
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU

These factors should be considered as important elements in any company safety program
and should be used as means for overcoming and reducing construction safety problems in
Kampala district and Uganda at large.
The main causes of building construction accidents on site in Kampala district are related to
management and workers or human related factors; while the project nature factors have no
larger effect as revealed by the respondents on the ranking of accidents on building construction
sites.
Objective 3: The researcher suggested the following to be done in order to minimise accidents
on the building construction sites in Kampala district.
All Stake holders in the Construction Industry should know and perform their Duties and
Responsibilities.
Human resource is the most valuable form of resource but many workers are killed and
others injured because of accidents on construction sites. Safety in construction is one of the
most important but somewhat neglected aspects in the construction industry. Unfortunately, this
happens not only at the micro-level but even on a national level to some extent. With the
advancement in technology, the need for proper attention to the safety has become very
important. The wide range of construction and building operations with new and complex
techniques have brought new problems to light.
The construction industry employs a labour force which is more than that employed by
any other industry. It is also the least organised and as a result there is a scope for exploitation of
the labour. In spite of the recent legislations, the worker discontent is rampant and this has
created new areas of conflict. Above all, the lack of proper attention to occupational safety and
health measures has created a difficult situation. Stake holders are persons or companies that are
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
101
involved in a particular organisation, project or system especially because they have rested
interest in it. In construction, the main stake holders include the client, contractor, contractor‟s
employees, Designers/Architect, suppliers and manufacturers of materials and goods used on
site, local authority operatives among others. Nevertheless, safety is a concern for all in the
industry from the top management to the operative on site.
Contractor
Contractors who are one of the stake holders in the construction industry are obliged to
produce a statement of their overall policy regards to safety and their responsibilities are as
follows:
1. They are to provide and maintain safe plants and equipments, and safe systems of work.
Since a good number of accidents on site are attributed to plants, machinery and
transport. It is important that the contractors should provide adequate information on the
safe use of various items of construction plants. Most accidents connected with plant and
machines are caused by failure to observe the basic safety precautions. Therefore, the
contractors should provide adequate practical training for skilled operatives and
supervisors.
2. A contractor should arrange for ensuring the safe use, handling, storage and transport of
articles and substances. Materials and equipments must not only be loaded in a safe
manner but also with due regard to the safe unloading at its destination. With the
increasing usage of flammable liquids such as white spirits, paints and adhesives, the fire
prevention association should provide a guide on their fire safety. Bottled gases
commonly used on construction sites, also requires the same careful attention to safe
practices.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
102
3. A contractor should provide information, instructions, training and supervision necessary
to ensure the employees‟ health and safety on construction site. All contractors should
recommend safe practices and specific advice about various items of plants and potential
hazardous materials. All plant operators must be properly trained, experienced and
careful; and this requires some form of authorisation to operate them. Safety officers
should also be appointed on site, which have more than twenty (20) employees. They are
to assist the site management in the implementation of the construction firm‟s safety
policy and offer advice where necessary to ensure regulations covering safety are being
observed.
4. They should also ensure that all places of work have a safe means of access to and egress
from, that is without risk to safety and health. Particular attention is required in planning
offices, huts, canteens, disposal of rubbish, smoking, heating appliances, flammable
liquids and gases, machinery and welding appliances. Access to the works may involve
ladders, scaffolds or hoists in compliancy with the Act.
5. The contractor should provide and maintain a working environment that is safe without
risk to health and adequate as regards to facilities and arrangements for welfare at work.
First Aid kit and Ambulances, shelters and accommodation, washing facilities and
sanitary conveniences, and protective gears (jackets, over alls, over coats, helmets, safety
shoes, safety belts, boots, and goggles) all these should be provided by the contractor on
the construction site.
6. The contractor should have a sense of duty to other people other than the employees on
site. These are usually visitors or passersby, the client and consultants. They should
ensure that they are not exposed to risks as to their health and safety. The contractor
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
103
should give such persons the prescribed information about any aspect of the way in which
he/she conducts his/her undertaking as might affect their health and safety. The building
site should be fenced off from dangerous excavations and holes and the protection of the
public on disturbed pathways or in adjoining buildings. A notice should be put up for all
visitors warning of the inherent dangers on the construction site. The control of noise on
construction sites is necessary in the interest of both operatives and the community.
Employees
The workers on site are obliged to maintain and follow the safety and health regulations.
The following are their main duties:
1. The employees are to take reasonable care at work for their own health and safety; and
also for their colleagues and members of the public. This can be achieved by careful
handling of the materials and equipments on the construction site and even making sure
that they utilise properly the facilities which have been provided by their employers and
even ask for those that are missing.
2. The employees are required to cooperate with their employers to meet the requirements
of the occupational safety and health Act. When the employer implements some of the
regulations in the Act, the employee should be responsible and follow the
rules/precautions as stated in the Act.
3. The employees are also required not to be intentionally or recklessly abuse anything
provided in the interest of health, safety and welfare on the construction site. For example
misuse of protective gears, mishandling of hand tools, removal of sign posts prohibiting
people to go beyond a certain point, removal of lights by employees.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
104
Manufacturers and Suppliers
These are also stake holders in the construction industry who should implement health
and safety regulations on site. It is the duty of persons who design, manufacture, import or
supply any articles or substances for use on the construction sites to ensure that it‟s designed and
constructed as to be safe and without risk to health when properly used. In particular they must
make available adequate information about the use for which the article is designed and has been
tested; and about any conditions necessary to ensure that when put to that use it will be safe and
without risk to health. This usually applies to manufacturers/sellers of plant, equipment and
machinery used in construction operations and a wide variety of materials and chemicals also
used during the construction process.
Designers/Architects
Designers also have a responsibility to ensure that projects are designed to be of safe
construction when subsequently built. In civil engineering, this includes the safety of temporary
works such as methods of earth support, shoring, formwork and others in addition to the
structural stability of permanent works such as bridges, dams, and tunnels. The following are the
various roles performed by the Architect:
1. The Architect interprets the client‟s dreams. This is achieved by sitting together with the
client who explains to the architect his desired plans and interests, and then comes up
with the plan and outlook of the building. This plan is then subjected to discussions by
the client and the architect; alterations are made until the final plans of the house are
made.
2. The architect helps in developing and preparing the architectural drawings after reaching
a consensus with the client.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
105
3. The architect monitors the implementation of the drawings through regular visits to the
construction site.
4. Helps in developing architectural specifications of the project/building such as the type of
doors and windows and the roofing style.
5. Represents the client on the construction site, this is done so as to ensure that the proper
implementation of the architectural drawings and specifications is adhered to.
6. Helps in preparing the layout and arrangement of structures on any site such as the layout
of site offices, conference halls and welfare facilities.
7. In case of any query by the structural engineer about the architectural drawings, the
architect is always there to explain to the structural engineer such that the proper
structural drawings are made.
8. The architect issues certificate of completion after completion of project. The architect
also issues a certificate of making defects good, normally six months after the completion
of the project.
9. Arranges the inaugural meetings with the contractor to agree on certain pertinent issues
that may arise such as the pre-planning period before work is concerned. This is done
after the contractor has been selected.
10. Responsible for assembling other members of the construction team required for the
implementation of the project. These may include contractor, structural engineer and
quantity surveyors among others.
11. Works as an arbitrator in case there is disagreement between the client and any
construction team.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
106
Structural Engineer
1. Prepares the structural design of the building, which involves the structural analysis and
design to come up with the right member types and sizes for structural stability.
2. The structural engineer also helps in coming up with the structural drawings which act as
guidelines during the implementation of the building project.
3. Assist in the implementation of structural drawings, which is achieved through close
supervision of the construction.
4. The structural engineer ensures that the structure is sound (stable) and makes sure that the
work done complies with the structural plans.
5. Helps in developing structural specifications which include structural members and their
workmanship.
6. Advices the architect in some areas of the design where constructability is not practical.
7. The structural engineer plays a role of re-designing, modifying the structural design if
need be as the work progresses.
Local Authorities
Local authorities are also stake holders in the construction industry; they have a
responsibility to ensure that the construction site is located in the right place which is safe for
human use or the occupants and also for the employees who are working on the project.
Therefore, they should make sure that the construction does not interfere with existing main
services like electricity mains, water mains and the sewage mains. The local authority is to
ensure that the project is approved and it is inspected regularly to comply with health and safety
regulations on site. The following responsibilities should be undertaken by the Local/Urban
Authorities:
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
107
1. Ascertain the land ownership by the client where the building is to be constructed and
also helps in the preparation of the land titles.
2. Help to see that the project plans conform to the physical plans of the given area.
3. Help to approve building plans for purposes of suiting environmental and social
requirements of the area.
4. Help in providing security for the building construction project.
5. Provide preliminary information about the project site for example, information about the
geology of the area, like whether the site is susceptible to landslides.
6. Carry out supervision to ascertain that what was designed is what is being implemented.
7. Inspect certain stages of construction works of the building and issue inspection
certificates. Such stages include setting out, foundation and walling construction; and
roofing.
8. Approve modifications, alterations of the work under progress.
9. Provide approval to applications to carry out activities such as making connections to
existing sewers, details of drain/sewer depth and positions; opening up part of the roads
and highways where it is necessary to do so; erecting of hoardings, gantries and
scaffoldings; parking areas of plants and vehicles in congested construction sites; the
filling up of the highway with materials or dirt from lorries/damper wheels; deposition of
wastes from site rubbish and other unwanted materials from the construction site;
temporary water supplies for the site and make connections to the statutory bodies mains;
and temporary electricity supply and connections to the construction site.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
108
Uganda Institution of Professional Engineers (UIPE) should:
1. Help in furtherance of education and training in engineering, science and practice.
2. Give advice to government and public bodies on engineering matters.
3. Ensure proper health and safety measures are taken into consideration in the practice of
engineering
4. Set ethical standards of practice and disciplinary procedures so as to keep the required
standards of engineering.
5. Regulate and administer the practice of engineers.
The Occupational Safety and Health Department should:
1. Offer safety and health education and training to contractors and the general public.
2. Ensure that safety and health rules and regulations are observed on sites.
3. Approve architectural plans of buildings to ensure their compliance to safety and health
requirements.
4. Investigate accidents that occur on sites.
Health and Safety personnel must be familiar with:
1. The current occupational Health and Safety Act and Regulations for construction
projects.
2. Procedures in the event of an emergency
3. Procedures for refusal to work where health and safety are in danger.
From the numerated roles and responsibilities above, it can be observed that all the
stakeholders are in one way or the other concerned with the safety and health in the construction
industry.

Issues to consider in Prevention of building construction site accidents
Prevention is better than cure. Prevention of accidents and elimination of their
catastrophic consequences can be well effected when the building project team establishes the
hazards breeding accidents and devise means of mitigation.
It is often argued that if consideration is given to the hazards faced in any construction
work and appropriate precautions taken, accidents can be guarded against. However, this
requires that the precautionary and preventive measures as well monitored. (Ridley 1998)
Lubega, Kiggunda and Tindiwense (2002) suggested that; ‘an effective accident
prevention programme should take careful consideration of satisfy requirements for the
following adequate designs, quality of materials, construction work techniques, adequate
supervision and safety rules and regulations.’
Adequate designs
A good building project design should incorporate an allowance for the risk element.
Accidents due to structural failures can be controlled using adequate design practices. Design
work should follow codes of practice and specifications to ensure structural sufficiency in terms
of safety.
According to Blake (1989); „building plans should meet the requirements with loading,
ground movement and disproportionate collapse. The building should be so constructed that the
combined dead, imposed and wind loads are sustained and transmitted to the ground safety and
without causing such deflection or deformation of any part of the building.’
A good design should involve weighing the risk to safety (and good health) produced by
the design against the cost. Economic feasibility, fitness for purpose, aesthetics, environmental
impact and build-ability are other major considerations design of a building and which must be
reconciled with safety.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
110
P. P. Dharwadker (1996) noted that; „the prime deficiencies lie at the basic layout and
design stage of high rise buildings which is the responsibility of the architect or consultant and
central construction organisations or public sector companies or statutory bodies............ safety
measures must start at the planning and design stage of tall structures; planners, architects and
engineers should keep safety of workers and users of premises upper most in their minds.’
The duty of the project team can thus be recognised as an important one in preventing
accident occurrence and controlling likely consequences to improve site safety.
Quality of materials
Materials used in building process include bricks, aggregates, timber, steel, blocks,
cement, water, lime, and roofing materials. Their quality should comply with the standard
specifications for materials. Building materials that are not stronger enough will not produce
sufficient strength of the structural elements which are said to be of poor quality. And their effect
is reducing the structural strength of the overall structure. The likelihood of accident occurrence
is increasing as a result of possible structural failure. It can be noticeable that use of the
recommended and right quality of materials is a move to ensure safety in building construction.
Construction work techniques
Materials preparations, handling and placement are important aspects of safety.
Construction of structural elements and false works should be as to avoid failure. These are some
ways of incorporating appropriate techniques in order to ensure safety and guard against
accidents. Attention is particularly required in concrete batching, laying, compaction, installation
and striking of formwork, ladders and scaffolds; use of excavation plant, lifting cranes, and
coordination of all activities. Effective techniques should try to eliminate unsafe acts and ensure
a safe working environment. Conflicts in on-site movements should also be minimised by
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU
111
appropriate techniques. A number of site accidents associated with structural failures of building
components have been due to largely poor construction techniques.
Adequate supervision
Design teams and supervisions are supposedly required to follow up and supervise
construction works, if the failures and accidents are to be minimised. Cases of cave-ins and
electrocutions, through not very common here, often result from negligent practice but also due
to inadequate inspections and general supervision of the site operations. Even structural failures
and avoidable accidents are left to occur due to weakness in supervision of the site operations.
Even structural failures and avoidable accidents are left to occur due to weakness in supervision.
Supervision is to ensure that activities are carried out as scheduled and that safety precautions are
observed. Therefore, the supervision team should comprise of at least a structural engineer, an
architect, a safety inspector, together with the operations foreman and services-water specialist,
electricity specialist. When regular supervision of the site activities is effected, accidents can be
reduced to an absolute minimum.
Safety rules and regulations
Enforcement of safety and health regulations should be well effected and maintained to
promote safety and reduce the occurrence of accidents. Appropriate rules and regulations are
made by policy makers and enforced by the labour organisations with the help of police. In
addition, according to Michael Armstrong (1979), ‘top management should determine and must
be continuously involved in monitoring the health and safety policies equipment of the
organisation and ensure that corrective action is taken when necessary. Management and
supervisors must be made fully accountable for the health and safety performance in the areas
they control.’

P. P. Dharwardker (1996) observed that; ‘in USSR and East European countries,
accidents in the construction industry are viewed more seriously and there are in-built
elaborated safety organisations which ensure that the requirements of occupational safety are
adequately taken care of, and hence the incidence of fire and other accidents are reported to be
comparatively lower.’
Safety and health education/training
According to Michael Armstrong (1979); „all employees in an organisation should be
given thorough training in the safe methods of work and should receive continuing education and
guidance on eliminating health and safety hazards and on prevention.
It is generally believed that training is an important factor in improving safety performance. For
training to be effective, however, it must be planned in a systematic and objective manner. Safety
training must be continuous to meet not only changes in technology but also changes in the
environment in which an organisation operates the structure of the organisation and perhaps most
of all people involved. The safety training cycle is illustrated in the figure 2.1 below.
Safety training activities can be considered in form of a plan-do-check-act continuous
improvement cycle the elements of which are:
1. Ensure training is part of safety training
2. Allocate responsibilities for safety training
3. Define training organisation
4. Establish training organisation
5. Specify safety training needs
6. Prepare training programmes and materials
7. Implement and monitor training
8. Assess the results

9. Review the overall effectiveness
Recommendations
Management of the building construction sites should be careful by observing well all
safety precaution especially in the months of April – June, October – December; and also during
rainy periods as most of the accidents occur in such periods as revealed by the research.
The employers on the building construction sites should value their workers and stop
pushing them to do activities even if these workers are not capable of handling such activities;
should also know the workers‟ health status and be kept in records to be used by relevant
authorities.
The employers should also motivate workers by appreciating them whenever a task is
complete. This will show a sign of belongingness on the side of workers and hence improve their
performance while on their respective duties.
Employers should provide training courses and programs to increase attention to safety
and to prepare plans for sudden accidents and disasters. These courses should be conducted in
the languages well understood by the workers. The management should also observe the
performance of inexperienced workers to see if they need further orientation and/or training.
Specific strategies for reducing the likelihood or negative consequences of human errors can be
achieved by selecting people with the capabilities and skills required to perform job. This will
result in fewer errors being made and proper training of personnel. Improving the design of
equipment, procedure, and environments can improve the performance of people, including
reducing the likelihood and consequences of errors.
The government of Uganda should fix a minimum wage, resting time while on duty,
welfare facilities on site; and percentage of female workers on the building construction sites.
Luwalaga John Groover, 2009-MPH-FT-010, Research Dissertation, IHSU

This research revealed that workers are exploited as it is seen evidently by high turnover of
workers on building construction sites.
Other recommendations are directed towards the institutional level, encouraging
coordination and sharing of information with safety departments in the governmental authorities
and insurance companies. The government should ensure that all workers on the building
construction sites are insured. The educational institutions educating people who are going to
work on the building construction sites should incorporate safety as a course unit in their
curriculum. Uganda institute of professional engineers (UIPE) should work out a modality of
attracting more graduate engineers and also hold safety seminars on the building construction
sites.
The researcher suggests that accident prevention should be a responsibility of everyone; it
should actually start at home. Whereby all children should be taught at an early age on how to
safe guard themselves, others, and the equipments. A lot has been done in the name of reducing
accidents but there is no change. It is high time parents, guardians, community leaders and
teachers to take on this responsibility also of teaching the children of this country about safety
issues.
