Site safety
1.0 site plan
1.1 Introduction to site safety
Construction sites contain many risks that faced by both
of the construction workers and the general public. A
construction site is legally required to follow the
regulations and guidelines set by the department of
occupational safety and Health and other government
agencies to ensure the safety of the workers and public.
These guidelines apply to all work areas with building
operations activities in Malaysia according to the
Occupational Safety and Health Act 1994 (Act 514), the
1.2 SIGNAGE
Factories and Machinery Act 1967 (Act 199) and all
other relevant regulations.
The guideline dictates that every owner, developer,
main contractor and such contractor must take steps to
develop and promote safety and health programs to ensure
the safety and health of both his employees and the
general public. Safety signs are commonly found around
construction sites containing information, often symbols
relevant to site safety. Figure 1 shows symbols that
explain without the use of much words of what the workers
and public should and should not do around the
construction site. The use of simple universal symbols is
effective because in some cases the construction workers
or the public might be illiterate or might not be
f1a.mi3l ihaora rwditihng the language used on signs.
Hoarding is a prerequisite for a construction site
because it is legally required to protect the general
public from the risks associated with construction sites.
Hoarding is temporary fencing which is laid out around
the site, defining its borders. Aside from safety,
hoarding is also used for security purposes, preventing
trespassing and theft in the construction site. The
construction site uses metal hoarding. Metal hoarding
usually uses corrugated metal sheets as temporary
fencing material. Figure 2 marks the borders of the
construction site where boarding is used.

2.0 Earthwork Introduction
Definition
Excavation and piling of earth in connection with an engineering operation.
It involves movingpart of the earth to another location to create a
desired shape.
Machinery used:
Much of the excavation is done with operated machines to ease work,
cost and also saves time. These equipment includes:-
Equipments Function
Wheel Loader Scoop up lose materials from the ground from one point to another without pushing the materials
across the ground
Back Hoes Dig up hard materials and trenches
Scrapers Machine to move earth over short distance (smoothen)
Excavators Digging, demolition, forestry work, grading, landscaping, heavy lifting and brush cutting
Motor Grader Finish grade the rought grading created by heavy vehivles (Created flat surface)
Rollers Use to compact the soil after grading

Earthwork Excavation
Types of Excavation
There are different types of excavation and it is classified by the type of materials
Type of Excavation Description
Topsoil excavation Removal of the exposed layer of the earth’s surface, including vegetation. Contains more
moisture than that underneath.
Earth excavation removal of the layer of soil immediately under the topsoil and on top of rock. Used to
construct embankments and foundations
Rock excavation removal of a formation that cannot be excavated without drilling and blasting. Any boulder
larger than 1⁄2 yd3 generally is classified as rock.
Muck excavation removal of material that contains an excessive amount of water and undesirable soil.
Removal of water can be accomplished by spreading muck over a large area and letting it
dry, by changing soil characteristics, or by stabilizing muck with some other material,
thereby reducing the water content.
Unclassified excavation removal of any combination of topsoil, earth, rock, and muck. earthmoving must be done
without regard to the materials encountered. Much excavation is performed on an
unclassified basis because of the difficulty of distinguishing, legally or practically, between
earth, muck, and rock.

Earthwork Soil Testing
Introduction
The investigation of the geology and previous uses of any site,
together with the determination of its engineering, environmental
and contamination characteristics is fundamental to both safe and
economic development.
Soil Investigation Techniques that are employed for the project
are as followed :
1. Boreholes 2. In-situ testing
1. Boreholes
Rotary Boring is
boring hole using
drilling fluid (water
or mud) pumped
down a rod fitted
at the bottom some
sort of cutting bit.
2. In-situ Testing
In-situ testing techniques, Standard Penetration Testing,
Permeability Testing and Borehole Vane Testing are carried out in
the boreholes in order to provide information for geotechnical
design. Disturbed and undisturbed samples are retrieved from the
boreholes for inspection and logging by engineers and subsequent
testing in our laboratories.
Standard Penetration test (SPT)
Hammer weight = 65kg
- Drop height = 760mm
- Total penetration is 450mm and the
number of blows for the last 300mm is
the SPT’ N’ value.
Care
- depth of test vs casing L
*site supervision
Laboratory Test
Triaxial test
common method to measure the mechanical properties of many
deformable solids, especially soil (e.g. sand, clay) and rock, and
other granular materials or powders.
Unconfined compression
The objective of the unconfined compression test is to
determine the UU (unconsolidated, undrained) strength of a
cohesive soil in an inexpensive manner.

By tsang hao ren

Earthwork Cut and Fill
Cut and fill
the process of constructing railway, road or
canal whereby the amount of material from cuts
roughly
matches the amount of fill needed to make
nearby embankments, so minimizing the amount of
construction labor.
Various sections of a roadway design will require
bringing in earth. Other sections will require earth to
be removed.
THE MASS DIAGRAM
The mass diagram is one method of analyzing
earthmoving operations. This diagram can tell the
engineer where to
use certain types of equipment, the quantities of
materials needed and the average haul distances etc.
The mass diagram has many limitations that preclude its use in all
earthmoving operations. At best, it is merely a
guide indicating the general manner in which the operations should be
controlled.

3.0 Foundation
DEEP foundation
Deep foundations extend down through unsuitable or unstable soil to transfer building loads to a
more appropriate bearing stratum. The two principal types of deep foundations are pile
foundations and caisson foundations.
This is usually at depths more than 3 meters below the finished ground level.. If unsuitable soils
are found at the surface, Deep foundations can be used to transfer the loading to a deeper, more
competent strata at depth.
Piles caissons
Caissons are a form of deep
foundation which are constructed
above ground level.. A DRILLED,
CYLINDRICAL FOUNDATION SHAFT

Foundation
Pile cap foundation on site
Pile Cap foundations allows any type of structure to be supported
by layers of soil. When the upper layers of the ground are too soft,
Pile Cap Foundation is used to provide proper support to the weight
of the building. These piles will penetrate these 'soft' layers into the
stronger layers beneath..
At our site, deep foundation is applied. The building loads are
transferred to a better bearing stratum of rock or dense sands and
gravels below superstructure.

Pile cap structure
Column load
Piles are usually driven in
clusters of two or more
The reinforced concrete pile
cap joins the heads of a
cluster of piles so that the
load can be distributed from
a column or grade beam
equally among the piles.
Piles are driven into earth
by pile driver, precast
concrete piles can be round,
square, or polygonal cross
sections or even an open
core. Precast piles are always
often prestressed.
Friction piles is used in our site. It
depends on the frictional resistance
of a surrounding earth mass for
support. The stiffness increases
when the the depth increases
A pile foundation is a system of end-bearing
or friction piles, pile caps and
also tie beams for transferring the
building loads to a more suitable bearing
stratum

The drop hammer friction piles are at this site. is the most commonly used method of insertion of
displacement piles. A pile, which is long with a cross section of circle, square or octagon and is usually made
out of either cement, wood or steel. It is forced vertically to pass through the soil using a pile driver.
The piles are grouped together and connected by a pile cap if the load is expected to be too large for the
foundation to take.

Column footings
Footings are an important part of foundation construction. The footing is the
bottom part of the foundation. A footing is typically concrete and typically
reinforced with steel. The usage of footings is to support the foundation and also
prevent settling. Footings are very important in areas, which have troublesome soils.
Placement of footings is very important so that it can provide the proper support
for the foundation and ultimately the whole structure.

4.0 Beam and ColumnsIntroduction
Beams
A beam is a horizontal structural
element that is capable of
withstanding load primarily by
resisting bending. The bending force
induced into the material of the
beam as a result of the external
loads, own weight, span and external
reactions to these loads is called
a bending moment.
Beams and Columns
Columns
a Vertical structural element that
transmits, through compression, the
weight of the structure above to
other structural elements below.
Structural System
Our site uses a structural system for its building.

5.0 Floor system introduction
A floor is a horizontal plane in a building that supports both living loads (people,
furniture/anything moveable) and dead loads (weight of the floor construction itself).
It acts as the lower enclosing surface of a room.
It transfers the load horizontally to the beam, column or load bearing wall...
floor system may composed of:-
• series of linear beams and joist overlaid with a plane of sheathing
• Homogeneous slab of reinforced concrete
Functional requirement of The floor:
1.Strength and Stability - able to withstand heavy weight of live and dead
loads, impact to the floor, without breaking/damaged.
2.Fire resistance - high fire insulation and not combustible.
3.Damp resistance - Moisture will take the floor damp, cool and uncomfortable
and may cause decay to the floor finish (I.e timber & carpet)
4.Sound insulation - thickness of floor affects amount of sound transmitted
to the lower/upper ground.
5.Thermal insulation - thickness/material of floor affects the thermal
insulation.

Sub frame is installed prior to the main frame. This is done so that the main
frame is less likely to shrink as it does not come in contact with the masonry wall.
The door frame is also not stained by paint or cement mortar. Floor finishes are
also easier to be installed as it does not need to suit the door frame profile.
Step 1 - The location of the door is
measured and marked according to the
dimensions stated at the approved construction
drawing. A few layers of brick are then
laid by its side.
Step 2  Frame of the door is then slotted
into the measured space. The jamb of the
door is nailed into the masonry wall for
support purposes and bricks are continued to
be laid.

Step 3  A pre-cast concrete lintel with same
width and length of the door is bound with
mortar and placed on top of the door head.
The lintel is constructed to prevent the door
frame from excessive vertical force and
affect its ease of operation.
Step 4  For timber door frame, the wall is
plastered and the main frame is installed.
For aluminium door frame however, the space
between the masonry wall is filled with mortar
before the wall is plastered.

Step 5  Shims are placed on the hinge side
of the door and form a continuous gap in
between. The hinge is then nailed into the
side door jamb.
Step 6  To ensure that the cracks and flaws
in joining is hidden particularly for timber
door frame as the wood will season and shrink
after some time thus exposing cracks, the
architrave is installed.
Advantages of Using Aluminium Frame
- Low maintenance frame.
- High resistance to corrosion.
- Strong and economical.
- Environmentally sustainable material.
- Easy to install due to its flexibility.

windows
By liau wen bin
Window is an opening in a wall or other structures that is operable in opening and
closing mechanism. It is the connection between interior and exterior space by
allowing the passage of natural light, solar heat, air movement and also
provide a view. Windows are undoubtedly important in achieving quality of life
and comfort in buildings.
TYPES OF WINDOWS
An awning window is hinged at the top and
opens outward.The glass protects the opening
like an awning, enabling ventilation even
dying rainy weather. It can be placed high
on the wall to let in both light and air.
Generally, awning windows are opened with a
hand crank. Screens are on the inside of
the window, where they are more protected
from the elements.

When open, the sash is
able to direct
ventilation. The
sashes may be stacked
vertically with sashes
closing on each other
or on meeting sites.

9.0 Roofing system
Definition of roof
By chew ung
A roof is part of a building envelope that covering on the uppermost part of a
building or shelter which include exterior surface and its supporting
structures. It must be able carry its own weight, additional attached
equipment and accumulated rain. Furthermore, it must be able to resist wind
pressure
Basic function of roof
 Able to resist the passage of moisture to the inside of
building.
 Able to withstand atmospheric pollution, frost and
other harmful condition
 To prevent the spread of fire over the roof and
from one building to another.
 Thermal insulation is required to reduce heat losses
and prevent excessive solar heat gains in hot
weather.
 Sound insulation is rarely an important consideration
in roof design.
TYPE OF ROOF
There are different kind of roof (refer diagram2). The shape of roofs differs
greatly from region to region and it affects the overall appearance of a
home. The main factor which influence the shape of roofs are the climate and
the materials available and the outer covering, appearance and aesthetics,
maintenance and costing

Introduction of Flat Roof
By chew ung
A flat roof is a roof which is almost level in contrast to the many types of sloped
roofs. The slope of a roof is properly known as its pitch and flat roofs have up
to approximately 10.Flat roofs are an ancient form mostly used in arid climates
and allow the roof space to be used as a living space or a living roof.
Introduction of Butterfly Roof
A roof shape which has two surfaces that rise from the centre to the eaves
with a valley in the centre, resembles the wings of a butterfly.
TYPE:
The shop lots use two kinds of roof which are Reinforced concrete flat roof and
butterfly roof at the top of those shop lots

TYPE OF FLAT ROOF
By chew ung
Most of the materials that used in the flat roof provide insufficient
resistance to the transfer of heat to meet the requirement of the building
regulations. Therefore an insulating layer is needed. The position of the
insulation will define the type of flat roof.

Steel is defined as any alloy of iron with content of 2 percent and below. Steel
is strong in both compression and tension. Galvanized steel is kind of steel that is
coated in zinc which can prevent rust. The process is achieved through hot dip
galvanizingCorrugated roofing panels span between beams or purlins running across
the slope. The roofing panels can be aluminium, corrugated structural glass,
fibreglass or in the case of the shop lots in Banting, galvanized steel.

Butterfly Roof
By yap chein
Butterfly Roof basic structure
A butterfly roof consists of two roofs
joined at their low points to form a
valley, which sometimes serves as a
reservoir. The angle of the two roofs is
determined by the architect or designer,
but it typically creates slight but
visually discernible slopes that give the
building a more modern and less angular
appearance than that of a traditional
roof.
Butterfly roof versions
Several unique styles of roofs have
emerged based on the atypical pitches of
butterfly roofs. A shed roof has a single
slope and typically includes the slope at
different levels on top of the building. A
saddle roof is shaped like a Western style
saddle used to ride a horse, with a convex
curve on one side of the axis and a
concave curve on the other. Gabled
butterfly roofs generally have a
triangular sloping roof attached to a flat
roof with windows placed near the top of
the walls beneath it. Zigzag roofs look
like the edge of a saw blade, with many
acutely angled peaks in a row. Architects
sometimes mix and match roofs of different
pitches on a single structure.
