2.0 Site and Safety

Our chosen site is the Storey Terrace House in Kesuma Lakes, Beranang and the lorry factory site in Semenyih. In a site, there are

lots of safety protocols and regulations to be followed in order to reduce accidents from happening. Before entering a site, visitor or

workers are required to wear some equipments in order to protect themselves from construction site incidents like falling object.

Falling Object

Precaution against falling is still improvable. The site does not

provide proper equipment for the workers to go up and down

from the building.

Plate Vibratory Compactor

It is an engine-powered, walk behind machines that impact vibratory

compaction effort to lose materials and asphalt via a bottom-mounted

steel plate that might vary in area from 1.5 to 3 square feet. An

eccentric drive mechanism propels the compactor forward, and if the

compactor is 'reversible', the mechanism also propels the machine in

the opposite direction.

3.0 EXTERNAL WORK

It is a service provided around building to provide

convenience to the occupiers of the building.

SITE LAYOUT

It is prepared by the contractor before the work on site

commences as part of their mobilisation activities.

The site layout has to include the location of cranes, site offices,

welfare facilities, off-loading and storage areas, sub-contractor facilities,

car parking, entrances, temporary roads, separate pedestrian access,

signage, temporary services and etc.

Advantages of a well-planned site layout:-

To gives a good impression to the general public.

Improve the productivity.

To help in directing plant and materials deliveries.

To reflect on the efficiency of the site management by reducing

waste and eliminating unnecessary movement of plants and

materials.

When planning the site layout, we should consider the site activities,

efficiency, movement, control, accommodation for staff and storage of

materials.

MANHOLE

It’s a tube which connects underground utilities to the surface which

is large enough to accommodate the body of utility workers. It can be

found connected to water and sewer systems, along with electrical and

fibrotic cabling. In all cases, manholes are located at primary junctions,

and sometimes at intervals along the utility line, to allow workers easy

access to potential problems.

Manhole is located when there is:-

Change in drainage pipe direction

Junction

Change in ground levels

Change of drainage pipe size

Long pipeline

External Work By Farah Akmal 15

Page 18: PROJECT 1 (BUILDING CONSTRUCTION 1)

It is covered with a top that is flush to the ground called manhole

cover. Manhole cover comes in many shapes which is square, round

shape, ‘T’ shape and ‘L’ shape.

Purpose of having manhole:-

Inspections, cleaning and removing of the obstruction are carried

out in the sewer line.

It allows sewers to be attached, or alternating the direction or the

alignment of the sewers.

It can be used to facilitate the laying of sewer line in convenient

lengths.

FOUNDATION Foundation (also known as Base work) is the lowest and the most basic form and work to make an architectural structure possible to be built.

Procedures of Constructing Foundation

Setting out for footing

Marking of the spot of the footing / foundation To show also the area and space required to construct the foundation Use a wooden stick to mark the edge of the area

Removing the soil of the selected spot Using excavator to remove the soil

Excavation of pit for footing

Proper compaction to base footing

Compact and strengthen the soil of the base of the footing using compactor

Put up formwork of the footing Make sure every planes is supported with enough strength Adjustments to the form cannot be made after the concrete is poured because concrete is very heavy

4.0 FOUNDATION

Foundation (also known as Base work) is the lowest and the most basic form and work to make an architectural structure possible to be built. Before the

construction of foundation, detailed soil investigation is carry out to determine the type of foundation needed to construct in order to be able to support the

structure. Organization and analysis of all available information about the structure to be supported and the subsurface condition is also taken into

consideration. Optimal foundation solution transfers the structural load to the ground in a way that minimizes costs over the life of the structure without

sacrificing safety or performance.

Additional Information on Foundation Construction

Excavation:

Types Description

Common Excavation

The excavation of all materials that can be excavated, transported, and unloaded by the use of heavy ripping equipment.

Rock Excavation

The excavation of all hard, compacted or cemented materials that requires blasting or the use of ripping and excavating equipment larger than defined for common excavation.

Compaction:

Soil before compaction Soil after compaction

-Large space between soil particles which leads to more flow and easily movable particle -Loose soil leads to poor load support

-Less space between soil particles which makes the matter more solid and smooth on the surface -Compacted soil improves load support

Formwork:

Components Uses

Sheathings The vertical planes that form the shapes of the concrete poured into the formwork.

Cleats The supporting elements on the top side which holds the opposite sheathings together when the heavy concreted is casting in and prevent tilting or the sheathings .

Studs The supporting elements on the side of the Sheathings which maintain the straightness of the sheathings when concrete is casting in.

Braces The additional supporting elements which hold the sheathing vertically in place by connecting the sheathings to the ground to withstand the weight of he concrete.

Stakes The cleats-like component which hold the formwork to the ground, making them stand firmly in place.

Wires Thin strings that hold opposing sheathings together by connecting the opposing cleats together.

Foundation By Loh Khai Jhung 19

Page 22: PROJECT 1 (BUILDING CONSTRUCTION 1)

Concrete Curing:

Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time. Properly cured concrete has an adequate amount of moisture for continued hydration and development of strength, volume stability, resistance to freezing and thawing, and abrasion and scaling resistance. Factor affecting the curing process of concrete: - Mixture proportions - Size and shape of concrete member - Ambient weather conditions - Future exposure conditions

Slump Test:

The slump test result is a slump of the behavior of a compacted inverted cone of concrete under the action of gravity. It measures the consistency or the wetness of concrete. The test is carried out using a mold known as a slump cone.

Procedure of Slump Test: 1) The cone is placed on a hard non-absorbent surface 2) This cone is filled with fresh concrete in three stages, each time it is tamped

using a rod of standard dimensions 3) Concrete is struck off flush to the top of the mold 4) The mold is carefully lifted vertically upwards 5) Concrete subsides 6) The result is then taken down

(Different uses of concrete should have different results from this test)

5.0 SUPERSTRUCTURE A superstructure is an upward extension of an existing structure above a baseline.

This term is applied to various kinds of physical structures such as buildings, bridges,

or ships.

Super-structure is that part of the structure which is above ground level, and which

serves the purpose of its intended use.

Superstructure of a building consist of:

Staircase

Beam

5.1 BEAM AND COLUMN

Columns

A column or pillar in architecture is a vertical structural element that transmits, through

compression, the weight of the structure above to other structural elements below.

Construction site:

First, tie up rings around and into vertical steel bars, according to shape and design.

Nextly, fix the form work according to required size with vertical steel bars.

Then, pour reinforced concrete in form work according to design and size using

bucket-casting method.

Steel

Bars Rings

Wooden

formwork

Bucket with concrete.

Superstructure By Chong Chui Wern 22

Page 25: PROJECT 1 (BUILDING CONSTRUCTION 1)

Lastly, remove the form work and do proper curing.

Additional information: Wooden formwork is used as it can be constructed at a lower

initial cost than steel because of higher availability and lower production costs.It

requires no special tools nor high level construction experience. It is also easier to

handle due to its lighter weight.

Beam

A beam is a horizontal structural element that is capable of withstanding load primarily

by resisting bending.

Building of the ground floor beams.

The building uses cast in-situ to build the first floor beam. These will be supported by

walls or columns and the construction of a beam will require formwork. Once formwork

has been erected, reinforcing steel is fixed, making the necessary connection to the

reinforcement in the supporting elements. The side formwork is then fixed. The

concrete is then cast. Curing takes place after that.

Building of roof beams.

Scaffolding is used as

support for the cast

di-situ beams.

Page 26: PROJECT 1 (BUILDING CONSTRUCTION 1)

Cutting of concrete

Additional Information:

Curing is the process where the concrete is protected from loss of moisture and kept

within a reasonable temperature range. This process results in increased strength and

decreased permeability. Curing is also a key player in reducing cracks, which severely

impacts durability of concrete.

Before Curing After Curing

Advantages:

1. Durability

2. Possess adequate stiffness

3. Termite resistance

4. Damp resistance

5. High speed of construction

6. Fire resistance

Disadvantages:

1. Not east to rectify on defects

2. Cannot be satisfactorily repaired

3. Weak heat insulation

4. Weak sound insulation

5.2 Floor

- Floor slab: A flat piece of concrete, typically used as a

walking surface, but may also serve as a load bearing

device as in slab homes. Concrete slab floors come in

many forms and can be used to provide great thermal

comfort and lifestyle advantages.

- Slabs can be on-ground, suspended, or a mix of both.

They can be insulated, both underneath and on the edges.

According to our site, there are two types of slabs are being used.

Concrete floor

Advantages:

1. Easy handling as it’s light weight

2. Easy to disassemble

3. Damaged parts can be replaced

4. Very flexible

5. Easy to produce and easily

available

Disadvantages:

1. Limited re-use

2. If timber is dry, will absorb

moisture from wet concrete

3. Time consuming for large

structure

4. Required high quality labour

force

Formwork which has been accurately built is

assembled on the ground to prepare for

construction

The concrete is poured into the ready formwork.

The workers are undergo a process of Screeding

Why Timber formwork is used?

The construction for ground floor slab

is completed

1. The worker is levelling the concrete with a straight edge using a back and forth motion while moving across the surface.

Screeding: process removes excess concrete and brings the

top surface of concrete to a proper grade.

Superstructure By Lee Yen Chei 27

Page 30: PROJECT 1 (BUILDING CONSTRUCTION 1)

Construction of Upper Floor Slab

The method of upper floor construction is cast in situ.

The concrete is lifted up by the crane.

Suspended slabs are slabs that are not in direct contact with the ground. They form roofs or floors above ground level.

Suspended slabs are grouped into two types:

one way slabs

-supported on two sides

two way slabs

- supported on all four sides.

Superstructure By Lee Yen Chei 28

Wiring system is fixed before the

application of concrete slab

One way slabs

usually rectangular where the length is

two or more times the width. These

slabs are considered to be supported

along the two long sides only even if

there is a small amount of support on

the narrow ends. The width of the slab

is also the short span.

Two way slabs

are approximately square where the

length is less than double the width and

the slab is supported equally on all four

sides. The pressure spans equally

across the width and length of the

concrete slab.

The workers are building a temporary

formwork for the upper floor concrete slab

The upper floor slab is completed

Types of wall

5.3 Wall

Building walls purposes are to support roofs, floors and ceilings,

enclose a space as part of the building envelope, along with a

roof to give buildings form, and to provide shelter and security.

In addition, the wall may house various types of utilities such

as electrical wiring or plumbing.

Solid Wall

Load- bearing wall

masonry wall, constructed of either brick, or blocks of stone, or concrete laid in mortar with blocks laid to overlap in bonding or as monolith (one solid interrupted material such as concrete which poured wet and hardened)

Frame Wall

Non-load bearing wall

Constructed from a frame of small section of timber, concrete or metal joined together provide strength over both faces where thin panels are fixed with some material

Load bearing wall

Non- load bearing wall

Non- load bearing wall is the wall that does not support other load

except its own. This wall is constructed on building which has frames

such as columns and concrete beams. The wall thickness is

sufficient only half a brick and normally constructed with stretcher

bond.

Load bearing wall is constructed to support the load other

than its own. The wall will support all loads before

transferring to the foundation. This wall uses reinforcement

steel bars or is combined with columns to strengthen its

position.

Superstructure By Lee Yen Chei 29

Page 32: PROJECT 1 (BUILDING CONSTRUCTION 1)

Load Bearing wall & Non-load bearing wall Site B

Site A

Our site B consists of two floors. The lower wall supports the floor

and wall above. The upper wall is non-load bearing since the weight

of the roof truss is totally borne at the trusses’ bearing points on the

outer walls.

For our site A, The top floor of the building is an open area, it does not

has a supporting roof. So the wall of the building built is non load

bearing wall. It does not need to support other load except its own.

Site B is a semi- detached bungalow. There are two types of walls. Standard Brick details

Masonry Wall

- The wall is built by clay bricks

- Openings are spanned with lintels

for installations of doors and windows

Party wall

- Is a dividing partition between two adjoining buildings (or units) that is shared by the tenants of each residence

- Acts as fire wall, slow down the spread of fire

To the neighbouring house

Masonry

Why Clay Brick is used?

Reason:

1. Thermal and Acostic insulation

2. Low maintenance cost

3. Fire resistance

4. Flexible in application

f

Every brick is separated by beds and

joints of mortar. The horizontal

section of mortars are called beds

and vertical sections joints. The

purpose of beds and joints is to allow

the slight variation in dimension of

each brick and to accommodate

slight structural movement of

building.

5.4 STAIRCASE

INTRODUCTION

Stairs are essential building blocks of any two-story construction projects. Stairs are constructed of three main things:

stringers, treads, and risers. Stringers are the diagonal 2x12s that carry the weight of the people walking up the stairs.

Treads are the top baseboards onto which you step, and risers are placed perpendicularly under each tread.

COMPONENTS OF A STAIRS

FUNCTIONITY OF THE STAIRS

-stairs been using for people climb it to another level of

the building. Instead of using elevator, people use

staircase to go to upper level of the building. It is also for

emergency exit. People can’t use the elevator during

emergency like fire alarm is ringing; they need to use the

stairs to exit from the building.

Superstructure by Nor Azalia Eliany 34

Page 37: PROJECT 1 (BUILDING CONSTRUCTION 1)

THREAD AND RISER RELATIONSHIP

1. All risers in the same flight must be equal.2. All treads

in the same flight must be equal.

3. For residences, the maximum height of a riser shall be

eight inches. (F.H.A. permits 8¼ inches.)

4. For residences, the minimum tread run shall be nine

inches exclusive of nosing.

5. The stair ratio: The height of a riser plus the width of a

tread shall equal not less than 17 inches nor more than

18 inches.

Minimum R + T = 17”

Maximum R +T = 18”

Below is an example on how to calculate it.

Page 38: PROJECT 1 (BUILDING CONSTRUCTION 1)

BASIC STAIR ANATOMY

There are three main components in a typical staircase:

stringers, treads and risers. Stringers, typically cut from 2

x 12s, are the sloped boards that support the other

components and carry the weight of people walking on

the stairs.

Window

Windows are known as an opening in a wall, door, or roof that allows the passage of light and, if not closed, air and sound. They

are usually glazed or covered in some other transparent or translucent material such as tinted glass. Many glazed windows may be

opened, to allow ventilation, or closed, to exclude inclement weather. They are held in place by various types of frames. There are

also lots of different types of mechanism window but this depends to their needs and purposes.

Construction Method of Window Frame

The method that we know about installing the aluminium

window frame from the site is straight install the main frame

with lug system to the wall. Therefore, there is no sub frame

needed in this process.

Mortar cement to hold

the aluminium window

frame become rigid at

the bricks wall

Black tape is used to cover the aluminium

window frame for protection from getting

corroded by the cement.

1) Measure the

dimension of

the rough

opening.

2) The rough opening

of window is cleaned

and wet.

3) The frame is

positioned by metal

straps with mortar

cement placed to make

sure the frame is fixed

at the wall.

4) The straps are prepared

to be anchored and make

sure the alignment of the

frame is in position. Then,

process of plastering can

be started.

Additional Information:

Material for window is green or black tinted glass glazing

which can prevent from heating and seeing through it.

7.0 ROOF

INTRODUCTION Roof is an exterior structure that provides shed to the body of a building. By having a roof, the building is able to withstand and protects the inhabitants from weather conditions (sunlight, rain, thunderstorm, wind, etc) and animals.

ROOF TYPES COMPONENTS OF A ROOF

FUNCTIONALITY OF ROOF

A roof has a basic function of withstanding atmospheric pollution, frost and other harmful condition

It is able to prevent fire spreading from one building to another

Heat lost and excessive solar heat gain can be reduced during hot weathers with the presence of various sheathing and underlayment in the roof

CONSTRUCTION OF ROOF

OPEN GABLE ROOF

1. Scaffolding or in other words a temporary propping 2. The trussed rafter roofs method is used in order to support the

is set up in order to support the framework of the roof. walls from spreading out when extra force is exerted on the roof.

3. A layer of plywood sheathing and roofing felt are laid on the rafters.

This is to act as an insulator for the building. After that, the metal roof panels are then laid on.

SHED ROOF 1. The framework of the roof is set up and is supported by a temporary propping.

2. The trussed rafter roofs are then set up be it with a metal rafter or wood and notch a slot which is also known as a bird mouth at the point where the rafters meet the wall. This is so that the rafter is able to sit firmly onto the wall. 3. Sheathing is then added and it is optional to place roof shingles or roof planks onto the sheath.

Summary

We visited two sites in total. Both are located in Semenyih. One is terrace houses in Kesuma Lakes,

and the other one is a lorry factory. By visiting those two sites we were able to explore and understand the

actual construction sites and how it works. We are more exposed to the basic principle and procedures of

the construction process. From pre-construction procedure, excavation processes, superstructure

constructions, utilities installations to the touching-up processes external works and roofing. We also

learned about how important it is to know about the construction of a building. For us who are taking

architecture course, we were able to know about the material which is suitable and efficient to be used for

the building environment. We were also exposed more to the construction technology and the extensive

detail of the construction. Our group consist of eight members divided our work equally to do this report.

This experience is something that we cannot get from the lecture class.
