CONSTRUCTION TIME OVERRUN Worldwide problem : seldom projects completed on time.

In Nigeria : 50% projects experienced time overrun with an averagepercentage escalation period up to 188%.

In Bosnia and Herzegovina : 51.40% project experienced time overrun

In Jordan : 82% of projects are delayed

In Saudi Arabia and Ghana : 70% of projects were delayed

In Malaysia : 18.2% of the public sector projects and 29.45% of private sector

projects only are completed on time.

Time Delay can be due to one or more reasons including problemsof financing and payment for completed works, poor contractmanagement, changes in site conditions, shortage of materials,design changes, weather condition, etc.

Initial conceptionalisation not captured and formalised beforecalling of Tenders changes during construction.

5/41

CONSTRUCTION COST OVERRUN

Cost is a major problem both in developed and developing countries.The trend is more severe in developing countries where these overruns

sometimes exceeds 100% of the anticipated cost of the project.

United Kingdom (UK) : nearly 1/3 of the clients complaint that their

projects generally experienced budget overrun.

In Nigeria : A minimum average percentage escalation cost of projects

was 14%.

In Slovenia : 51 % projects faced price overrun

In Croatia : 81% projects faced cost overrun

In Bosnia and Herzegovina : 41.23% of the projects faced cost overrun.

In Uganda : (Northern-by-pass project in Kampala) the cost overrun was

more than 100% of the contract price.

CONSTRUCTION COST OVERRUN

Worldwide research in transportation projects : 9 out of 10 projects face cost

overrun. The common overruns are between 50 to 100%.

In Malaysia : only 46.8% and 37.2% of public and private sectors projects

completed within the budget respectively.

The factors identified that contribute to cost overrun : lack of

contractor s experience, poor site management and supervision,

inaccurate time and cost estimates, schedule delay, frequent

design changes, fluctuation of prices of materials, cash flow and

financial difficulties faced by contractors.

CONSTRUCTION QUALITY

EXCESSIVE RESOURCES CONSUMPTION

Built environment has significant impact on resources : consuming

1/6 of the worlds freshwater withdrawals, 1/4 of wood harvest and

2/5 of materials.

About 40% of the energy used is linked to the construction and

maintenance of buildings.

Excessive resource and energy use : Resulted in growing demandfor raw materials, are largely responsible for the depletion of

natural resources worldwide, acceleration of global warming and

detrimental wastage affecting our ecological integrity.



7/41

CONSTRUCTION WASTE

Waste is one of the serious problems in construction projects. Waste has direct impact on the productivity, material loss and completion time

of project resulting in loss of a significant amount of revenue.

Waste contributes to around 30-35% of a project s production cost.

The amount of construction materials wasted on the site is relatively high and

equals 9% by weight of the purchased materials.

Construction waste can be generated because of one or more

reasons including frequent design changes, poor quality of

materials, workers' mistakes during construction, poor

planning, poor site management, ordering errors, materialsnot in compliance with specification, effect of weather, etc.

CONSTRUCTION WASTE

A study conducted on 30 construction sites in Malaysia identified

six types of waste materials which includes concrete (12.32%),

metals (9.62%), bricks (6.54%), plastics (0.43%), timber (69.10%)

and other wastes (2%)

Hence, it is timely for Malaysia to adopt a systematic and efficient

waste management strategy which would minimise the generationof waste at different level. Advanced tool likes lean construction

techniques can help in reducing waste at source and can

minimised the waste produced during the operation by re-using

and re-cycling.

Adopting waste minimization strategy like recycling and

reusing material can save 2.5% of the total budget.



8/41

CONSTRUCTION WASTE MANAGEMENT STRATEGY

ENVIRONMENTAL THREAT

Environmental Threat due to built environment : It consumes large

amounts of natural resources and produces a great deal of

pollutants.

Ethics of construction players: Not serious about environmental

protection at construction sites, assume that a construction site is

only a temporary setup, ignoring source of pollutants CO2 emission : Contributing to the global warming and extreme

weather.

Other Impacts : The harvest of timber leads to the lost of natural

forests, widespread use of toxic chemicals in materials.

Site clearings for development especially on slopes, etc.

SCHEME OF SUSTAINABLE DEVELOPMENT



10/41

SUSTAINABLE CONSTRUCTION

In November 1994, the First International Conference on SustainableConstruction held in Tampa, Florida, USA, the conference convener

Kibert defined sustainable construction as, Creating a healthy built

environment using resource-efficient, ecologically-based

principles. Sustainable construction involves a commitment to:

Economic sustainability increasing profitability by making more efficient

use of resources, including labour, materials, water and energy.

Environmental sustainability preventing harmful and potential irreversible

effects on the environment by careful use of natural resources,

minimizing waste, protecting and where possible enhancing the

environment.

Social sustainability responding to the needs of people at whatever stage

of involvement in the construction process (from commissioning to

demolition), providing high customer satisfaction and working closely with

clients, suppliers, employees and local communities

OBJECTIVES OF SUSTAINABLE CONSTRUCTION

Environmental dimension:

Increase material efficiency by reducing the material demand ofnon-renewable goods

Reduce the material intensity via substitution technologies

Enhance material recyclability

Reduce and control the use and dispersion of toxic materials

Reduce the energy required for transforming goods and supplyingservices

Support the instruments of international conventions andagreements

Maximize the sustainable use of biological and renewableresources

Consider the impact of planned projects on air, soil, water, flora,and fauna.



11/41

THE IMPACT OF THE BUILT ENVIRONMENT

OBJECTIVES OF SUSTAINABLE CONSTRUCTION

Economic dimension:

Consider life-cycle costs

Internalize external costs

Consider alternative financing mechanisms

Develop appropriate economic instruments to promote sustainable

consumption

Consider the economic impact on local structures.

Social dimension:

Enhance a participatory approach by involving stakeholders

Promote public participation

Promote the development of appropriate institutional frameworks

Consider the influence on the existing social framework

Assess the impact on health and the quality of life.



12/41

CHALLENGES IN SUSTAINABLE CONSTRUCTION

Shifting to sustainability : A new paradigm where sustainable objectives are

within the building design and construction industry. Key Action : The objectives should be considered in decision making at all

stages of the life cycle of the facility.

Figure below shows the evolution and challenges of the sustainable

construction concept in a global context.



13/41

GREEN BUILDINGS

Green building practices are: environmentally responsible and resource-efficient

to promote building practices that conserve energy and water

resources, preserve open spaces.

to minimise the emission of toxic substances

to harmonise with the local climate, traditions, culture and the

surrounding environment

to sustain and improve the quality of human life

maintaining the capacity of the ecosystem at local and global levels.

GREEN PERFORMANCE ASSESSMENT SYSTEM

IN CONSTRUCTION

(GREEN PASS)



18/41

Introduction

i. Green Performance Assessment System In Construction(Green Pass) is designed to meet this need through a standard

conformance that promoted sustainable construction in an integrated

manner with other with other Construction Industry Standards (CIS).

ii. This standard is based on minimum requirements for buildings and

systems using performance-related provisions and complements

existing standards to form a comprehensive assessment system for

green building construction.

iii. The Green PASS has incorporated international standards in its

development, specifically PAS 2050, Common Carbon Metrics(United Nations SBCI), United Nations GHG Protocol, ANSI and other

relevant standards inline with emerging global technological and

sustainability requirements.

Scope

The Green PASS estimates the carbon emission from building construction

works throughout a building s life cycle.

Assessment system covers construction, operations, renovation and

demolition.

The evaluation of Green PASS is divided into:

i. Building Construction

ii. Building Operations

Embodied carbon is referred to as COe 2 emitted during the construction or

retrofitting processes. Operational carbon is CO 2 emitted during building.

Green PASS adopt minimum standards of performance for baselings in key

areas e.g. water, waste, IEQ (Indoor Environment Quality)



19/41

Objectives of Green PASS

i. To evaluate the environmental impact of construction andoperational performance of building in relation to carbonemission reduction.

ii. To give due recognition for Low Carbon building constructionand operations.

iii. To align and support the Low Carbon Cities Framework andAssessment System (LCCF&AS).

iv. To encourage peer review of construction and operationsmanagement practices towards sustainable construction.

v. To increase awareness of carbon reduction and

environmental impact in construction and building operationsamongst project stakeholders.

The outcomes of the Green PASS provide information on the:

i.Baseline emissions and project emissions from five elements: Site,

Material, Energy, Water, Waste

ii.A non-GHG qualitative and quantitative analysis of Indoor

Environmental Quality,

iii.Percentage reduction in carbon emissions

iv.Opportunity for further improvement

Objectives of Green PASS



20/41

Application of Green PASS

Green PASS assesses the whole performance of abuilding in terms of carbon emission reduction basedon:

Site, Material, Energy, Water & Waste

while indoor environmental quality (IEQ) is aqualitative and quantitave assessment ofbuilding occupants comfort and overall

satisfaction.

GOOD PROJECT MANAGEMENT

PRACTISE

The Concept & Role of PM

in Construction Industry

The Rightful Roles :

- The Client determines the WHAT.

- The Construction industry determines the HOW.

- The Construction Industry is obligated to results,

based on key role of Project Management in

conceptual development, optimisation of know-howand innovative processes.

- Independent role of Project Management in protecting

Clients overall interest is assured as it is the

Project Managers main interest.

- Independent Project Management will result in

the right balance throughout the Project between

Budget, Quality, Time, Information & Organization

forcing all involved Parties to clearly focused on

Clients aim and objectives.

-The (non-technical) Client can focus on hisprincipal role in the Project without placing

a load on his organization. Thus, retaining his

valuable resources for his Core Business.

PREFBRICATION

It must be mentioned here that thetraditional in-situ constructionpractices leads to large wastage in theform of timber used for formworks,excess material, errors in dimensions

and measurements, high labourutilisation leading to high social costsand other forms of temporary works.

The use ofoffsite construction caneliminate the problem of wastagesubstantially and reduce constructiontime.

However, due to ease of securingrelatively cheaper foreign labourinnovative construction technologyand techniques has not made asignificant impact on the Malaysianconstruction industry and as much,cannot provide the economies of scalethat is needed to transform theconstruction industry from one that is

labour intensive, to one that istechnology intensive.

VALUE ENGINEERING

VALUE ENGINEERING AND MANAGEMNET

Value Management and life cycle costing is about managing

overall development process by making the appropriate

decisions when one moves from one phase of development

to the other based on 5 basic controls:-

TIME, COST, QUALITY, ORGANIZATION and INFORMATION

It does not happen by chance or when the need arise. It has

to be planned and structured to make it happened

affectively.

Value management is NOT just a cost cutting exercise.

AUTOMATED CONSTRUCTION

According to the Architectural Institute of Japan, 150 types of

construction robots have been developed in the field of building

construction.

Robots category

Robots for structure construction works , including fire-proofing, steel

welding, iron-bar placing, concrete placing, concrete finishing, and remote wire-

releasing. Robots for work completion, including exterior wall spraying, ceiling panel

placing, and light-weight wall panel handling.

Robots for inspection works, including outer wall tile inspection, and clean

room inspection.

Robots for maintenance works, including coating glass cleaning, and floor

cleaning.

A total of 12 systems has been thus far developed by eight

construction companies and introduced on more than 20 construction

sites.

Contribution : plays vital role in economic growth, helps in improving the qualityof life of its citizens

Negative Impacts : implication to the environment and social aspect of the

country, emission of CO2 by buildings contributed to the global warming and

extreme weather

Resource Consumption : About 40% of the world's resource and energy use is

linked to the construction and maintenance of buildings.

Green building approach : environmentally responsible and resource-efficient,

promotes building practices that conserve energy and water resources,

preserve open spaces, reduce energy consumption up to 50%, CO 2 emission

up to 39%, water used up to 40% and finally reduction in solid waste up to 70%.
