SITE CLEARING & EXCAVATION EARTHWORKS
Beforeconstructioncanbegin,certainsitepreparationprocedures
such as site clearing and excavation must be carried out. Site
clearing includes works such as the clearing way of trees and
stumps from the building site. Excavation includes the removal
of the earth, rocks and other ground material from site.
Some earthworks that must be carried out before construction
are grading and soil compaction. Grading is the work of ensuring
a level base, or one with specified slope depending on the type of
construction site. The earthworks created for such a purpose are
often called the sub-grade. Soil compaction is carried out in order
to increase the density and load-bearing capacity of soil. This
is a significant part of the construction process as if performed
improperly settlement of the soil could occur and result in
unnecessary maintenance.

SETTING OUT
Setting out is the establishment of the marks and lines to define the position and level of the elements for the construction works so
that works may proceed with reference to them. The settings out techniques used at the residential construction site were horizontal
control techniques where the structure is set out using permanent and non-permanent central points.
The figure above shows an
example of the setting out
of a structure in relation
to the construction site.
Primary site controls
are instruments used to
establish a second level of
control where secondary
Control points are used to
define important elements
of the scheme.
The figure above shows
the use of corner pegs and
offset pegs in setting out.
Both corner pegs and offset
pegs are used as the corner
pegs will be lost during
construction.
The figure shows the
permanent control point
used for setting out a
construction site. The
construction and protection
of control points is very
important and thus
permanent control points
must be durable and secure.
Wooden pegs are used for
making non-permanent
stations. They are also
called stakes and their use
in setting out is sometimes
referred to as staking.

CONSTRUCTION HOARDINGS
Construction hoarding is a temporary fencing used to secure
a construction site and is a prerequisite for any developer. The
hoarding defines the site boundary and prevents intruders from
entering the site. Authorised personnel can enter through the
access gate which can be locked after hours. The main purpose
of construction hoarding is for public safety as it discorouges
civilians from wandering onto the site and thus reduces risk of
their injury.
Information board is placed outside of hoarding at entrance site
Access for workersAccess for vehicles

SITE OFFICE CONSTRUCTION STORAGE
The site office is found on the construction site is a temporary
structure that is actually a portable cabin. It is durable and
functional on order to accommodate the intricate demands of
daily work on the construction site as well as reduce risks of
injury to the users.
The type of storage facilities used to store materials on the
construction site depends on the durability of the stored material, its
vulnerability to damage from weather and also its a financial value.
Materials that do not require protection from weather are merely
left in the open. This saves storage space for the more vulnerable
materials and provides easy access for the workers. Sometimes
temporary storage areas are used to store materials that required
protection from weather but will be used in a relatively short period
of the time. More expensive materials are locked in the storage
containers for protection from weather and theft.

SERVICES DRAINAGE
Drainage is a system of underground pipes used to convey
discharge from roofs, paved areas and sanitary fittings to a
suitable disposal installation. The usual method of disposal is
through the connection of the pipework to the public sewer, which
will convey discharges to a local authority sewage treatment
plant for processing.
Unplasticised Polyvinyl Chloride (uPVC) is used as the material
for the pipes at the residential construction site. The pipes are
supplied in standard effective lengths of up to 6m diameters
ranging from 75 to 150mm. A few advantages of using the uPVC
areeasierjoiningandlighthandling.Also,theyarelesssusceptible
to corrosion and breakage
The figure above shows a cross section of the residential drainage
system. Foundation encloses the drainage pipe system where
each PVC pipe is set in a bed of gravel.
The figure on the left shows a cross section of the residential
drainage system. It shows how the foundation is supported by
concrete footing.

SERVICES SEWAGE
According to the site manager, there will be a small space outside
the houses to locate the inspection chamber. In the inspection
chamberaresewageoutletsfromtoilets,bathrooms,andkitchens
that are connected to public sewerage pipelines to the public
sewage treatment plant. The checking and cleaning of blockages
can be done via the inspection chamber.
The residential sewer is an underground carriage system
specifically for transporting sewage from houses through pipes
to treatment or disposal. The sewage system is connected to
sewage pipeline that are directly linked to a sewage treatment
plant through a network of underground sewer pipes.

SERVICES RAINWATER MANAGEMENT
In fact, the design of the residential site optimizes rainwater by
conducting rainwater harvesting. Rainwater harvesting involves
the collection of water from roofs and hard standings and storing
this water for later use. The rainwater harvesting system to
be implemented at the residential construction site will allow
harvested rainwater to be dispensed from a hose to be used for
outdoor purposes.
Rainwater management is urgently suggested for ecological and
economic reasons. The project manager who led us around the
site even informed us that these days it is almost impossible
to get approval for a residential design without the inclusion of
proper rainwater management.

The figure above shows the completed water harvesting system.
The tank will collect water from down spout and the water will be
dispensed from the hose.

4.0 FOUNDATION A foundation is the lowest load-bearing
part of a building and is constructed partly
or below the surface below ground level.
The function of a foundation is to support
the superstructure above via transmitting
the load evenly and safely.

SHALLOW FOUNDATION
KEY ASPECTS OF A FOUNDATION DESIGN
DEEP FOUNDATION
A foundation is the lowest load-bearing part of a building and is
constructed partly or below the surface below ground level. The
function of a foundation is to support the superstructure above
via transmitting the load evenly and safely.
A type of foundation which transfer building loads to the earth/
soil on a very shallow depth and much different when compared
to deep foundation.
• Application and study of soil and rock mechanics
(Geotechnical engineering)
• Footing is designed structurally by a Civil & Structural Engineer
• Primary concern are Settlement and Bearing Capacity
• Able to safely carry compressive tension
Deep foundations are purposed to transfer loads from a structure
to the soil and earth which are much further deeper than a
shallow foundation works. Deep Foundations are also used when
the layer of the soil cannot support the weight of the building,
hence the load of the building must has its load transferred and
bypassing this layer to a stronger soil beneath the weak layer.
Deep foundations are usually extended much beyond shallow
foundation and is commonly used on buildings that has a heavy
and concentrated load such as a high rise building.

SINGLE FOOTINGS
RAFT FOOTINGS
STRIP FOOTINGS
Most common and simple type, used when the load of the building
is carried by columns. Each columns has its own footing. Footing
is just a square or rectangular pad of concrete on which the
column will sit on.

Most often used when basements are to be constructed. In a raft,
the entire basement floor slab acts as the foundation. The weight
of the building is spread evenly ove the entire footprint of the
building.
Strip footings are commonly used in load-bearing masonry
construction, it’s basically a long strip that supports the entire
wall. Usually found in older buildings made of masonry.

PILE FOUNDATION
Most common form of a deep foundation is a Pile Foundation. A
Pile is basically a long cylinder of a strong material that is pushed
or driven into the ground. Piles are commonly made with concrete
but in certain cases, steel and wood is also used. Concrete Piles
are precast.

page | 21
PILE CAP
A Pile Cap is a thick concrete “mat”that rests on the concrete piles
that had been driven. It provides a suitable stable foundation and
forms as a base for the building. The Pile Cap distributes the load
of the building.

PILE PENETRATION USING PRESS-IN METHOD
• Hydraulically pressing-in piles into the ground.
• Challenge construction pollution of excessive noise and
vibration on site that causes disturbance to the nearby
residential community.
• The precast piles are “injected” into the ground quietly and
steadily.
• Advantages of using the HSPD is that of the reduced pollution
of noise and voice, high accuracy via the usage of static forces
ensures the pile’s stability.
Piles are injected to the soil
hydraulically.
Pressure bulbs, or a compressed
soil area is formed around the pile.
This pressure bulb provides both
vertical and lateral strength to the
structure of the pile.

Pile Load Test (PLT) on site
PILE LOAD TEST (PLT)
A building’s structural soundness starts off with a strong
foundation, in which piles are commonly used. As part of
foundation’s quality assurance and control, Pile Load Test (PLT)
is necessary to ensure that the pile casted on site can take the
load of the structure.
APLTisdeemedfailedwhenthereisaninstabilityoftheKentledge
(Weight used such as concrete blocks), or failure of pile cap on
whatever reasons such as cracked, crumble and distorted from
its original shape or deflected from its original position.
The test load shall be maintained on the pile for at least 48 hours
and settlements & data shall be recorded at intervals. The test
load would then be unloaded in four equal decrements at one-
hour intervals until the full load is removed. Data readings will
be made immediately after and before every load is applied or
removed.
The maximum test load in a Working Load Test (WLT) would be
200% of the working load of a pile. Whereas the test load in a
Failure Load Test (FLT) shall be at least but not necessarily limited
to 300% of the working load of a pile.

Structural system support and transmit applied loads safely
to the ground without exceeding the allowable stresses in the
members.
Formwork is the use of support structures and moulds to create
structures out of concrete which is poured into the moulds. The
formwork here is made using wood.
A beam is a horizontal member spanning an opening and carrying
a load that may be a brick or stone wall above the opening, in
which case the beam is often called a lintel.
A column or pillar in architecture and structural engineering is
a structural element that transmits, through compression, the
weight of the structure above to other structural elements below.

5.2 SLAB
INTRODUCTION
TYPE OF SLAB (reference)
A floor slab is a common structural elements used in modern
buildings normally used as floor or a subfloor and it is a reinforced
concrete slab with a minimum thickness 5 – 6 cm. The floor slab
is a semi precast component that includes the lower floor slab
reinforcement that is required for structural reason.
One Way Slab
Grid Slab
Two Way Flat Slab
Hollow Core Slab

Flat slab placed
directly on the
concrete columns.
One way slab is a rectangular
slab , supported by its two
opposite long edge and free
of any support along the two
opposite edges. If force is
applied on the surface, the
slab will become curvy as
shown in Figure 1.
Two way flat slab is a two
way reinforcement that
usually does not have beams
and girders, and the loads
are transferred directly to the
supporting concrete columns.
Hollow core slab is also
known as a voided slab,
typically used in the
construction of floors in multi
story apartment building.
A waffle slab is a type of slab
that have two directional
reinforcement of the slab.
Giving it the shape of
pocket on a slab. A waffle
slab gives a substances
significantly more structural
stability without using a
lot of additional materials.
Waffle slab is normally used
in industrial or commercial
building.

TYPE OF SLAB (bangi site) INSTALLATION REQUIREMENTS
Slab type used: Hollow Core Slab
The photo is taken at the construction site where the
worker is now installing the hollow core slab. Hollow Core
Slab is normally use in the construction of floors for high
rise apartment or multi storey building. Compared to other
traditional method of construction, hollow core slab are
manufacturedusinghighlycustomatedhollowcoremachine,
through environment friendly manufacturing process.
1. Hollow Core Slab need to be installed followed by the
drawing.
2. Worker need to make sure that all the slab joint widths
uniform.
3. If the worker seek that there is a possibility of trapping
water in the cores, each core should be tapped near the
end to provide drainage.
slab | prepared by Yew Wing Kee
page | 35
INSTALLATION PROCESS
The worker will lift the hollow core slab near the end
of the slab, this is due to lifting the slab too far away
from the end may caused breakage.
Using erection clamp with safety slings for hollow
core slab that is width 4’ , when the worker was
attaching the clamp to the slab, they need to ensure
the clamp is level.
Next, they will pull the hollow core slab sling to
the adjacent erected slab. Worker will marked the
location of slab joints on the bearing area. This will
ensure the gauging of proper joint width and not
overrun or undercover the prescribed area.
After erected the slab, the worker will pull the lifting
clamps clear of the grout key after the crane lines are
slackened.
Therefore, a safe platform was form by hollow core
slab, the platform can used by worker to further
their work and a space where they can placed their
construction tools.
Finally, the last step will be pouring concrete in the
end of the slabs to integrate them with support.

TYPE OF SLAB (sepang site)
Slab type used: Concrete Slab
Concreteslabcancombinefooting,foundationsandsubfloor
as one piece. Slabs are cheaper to built than basement.
Slabs are best used on level ground and in warm climate.
They can be used where ground level is uneven. Most heat
energy is lost at the edges of slab. This loss is reduced by
using rigid insulation. In some extreme cases, heating ducts
can be built into the slab itself. This is very efficient and
provides building with an even temperature. The progress of
avoiding heat losing is shown in diagram below

INSTALLATION PROCESS
The worker in the picture above is excavating the site.
Excavation are made for the footings, drains , and
other floor features. These must all be deeper than
the rest of the slabs.
After the excavation is done, the corners are
relocated. Lines are restrung on batter boards and
the corners are plumbed. In the diagram below,
the footing forms for two piece slab are made like
standard footing or foundation form.
The worker have another easier way to construct the
floor slab which is using sand to spread evenly over
the form area. Install electrical pipes, sleeves for air
conditioning piping and wiring .
Then two workers will walk on the concrete slab, one
worker will placed the concrete and another worker
will pull up the wire. This is to ensure the strength of
the slab. After that , the workers will start pouring the
concrete to covered the form of the slab. They will
start pouring concrete from the corner of the form.
Finally, when the concrete is fully covered the slab,
the worker will wait for it to dry and they will start
cleaning up the site .

WHAT IS A WALL?
TYPES OF WALLS
WALLS ARE PLACED IN
A wall is a vertical structure , usually solid ,that defines and
sometimes protects an area . Most commonly , a wall delineates
a building and supports its superstructure , separates space in
buildings into sections, or protects or delineates a space in the
open air.
INTERIOR (WALL/PARTITIONS)
- Subdivides the space in the building
- Can be structural or non-bearing
- Provide required degree of acoustical separation
-Accommodationofnecessaryelectricalandmechanicalservices
EXTERIOR WALL
- Able to withstand horizontal wind loading
- Can serve as shear walls and transfer lateral wind and seismic
forces to the ground foundation if rigid enough
- Act as protective shield against weather
- Insulation toward air,sound,damp,moisture and heat

Wooden formwork is built by cutting it according to
the dimensions of steps. Stakes are braced firmly
and the diagonal braces are set firmly in the ground.
When all concrete is poured, a float is used to strike
off the concrete to create smooth surface.
After rebar, the concrete is mixed and it is poured
into the bottom step first. The process is continued
with each steps
After concrete is dried, the wooden formwork is
removed.

Site clearing includes works such as the clearing way of trees and stumps from the building site. Excavation includes the removal of the earth, rocks and other ground material from site. Some earthworks that must be carried out before construction are grading and soil compaction. Grading is the work of ensuring a level base, or one with specified slope depending on the type of construction site. The earthworks created for such a purpose are often called the sub-grade. Soil compaction is carried out in order to increase the density and load-bearing capacity of soil. This is a significant part of the construction process as if performed improperly settlement of the soil could occur and result in unnecessary maintenance.

  • 11. page | 11 SETTING OUT Setting out is the establishment of the marks and lines to define the position and level of the elements for the construction works so that works may proceed with reference to them. The settings out techniques used at the residential construction site were horizontal control techniques where the structure is set out using permanent and non-permanent central points. The figure above shows an example of the setting out of a structure in relation to the construction site. Primary site controls are instruments used to establish a second level of control where secondary Control points are used to define important elements of the scheme. The figure above shows the use of corner pegs and offset pegs in setting out. Both corner pegs and offset pegs are used as the corner pegs will be lost during construction. The figure shows the permanent control point used for setting out a construction site. The construction and protection of control points is very important and thus permanent control points must be durable and secure. Wooden pegs are used for making non-permanent stations. They are also called stakes and their use in setting out is sometimes referred to as staking. preliminaries work | prepared by Le Jia Ling

The type of storage facilities used to store materials on the construction site depends on the durability of the stored material, its vulnerability to damage from weather and also its a financial value. Materials that do not require protection from weather are merely left in the open. This saves storage space for the more vulnerable materials and provides easy access for the workers. Sometimes temporary storage areas are used to store materials that required protection from weather but will be used in a relatively short period of the time. More expensive materials are locked in the storage containers for protection from weather and theft.

The usual method of disposal is through the connection of the pipework to the public sewer, which will convey discharges to a local authority sewage treatment plant for processing. Unplasticised Polyvinyl Chloride (uPVC) is used as the material for the pipes at the residential construction site. The pipes are supplied in standard effective lengths of up to 6m diameters ranging from 75 to 150mm.

Rainwater harvesting involves the collection of water from roofs and hard standings and storing this water for later use. The rainwater harvesting system to be implemented at the residential construction site will allow harvested rainwater to be dispensed from a hose to be used for outdoor purposes. Rainwater management is urgently suggested for ecological and economic reasons. The project manager who led us around the site even informed us that these days it is almost impossible to get approval for a residential design without the inclusion of proper rainwater management.

SHALLOW FOUNDATION KEY ASPECTS OF A FOUNDATION DESIGN DEEP FOUNDATION A foundation is the lowest load-bearing part of a building and is constructed partly or below the surface below ground level. The function of a foundation is to support the superstructure above via transmitting the load evenly and safely. A type of foundation which transfer building loads to the earth/ soil on a very shallow depth and much different when compared to deep foundation. • Application and study of soil and rock mechanics (Geotechnical engineering) • Footing is designed structurally by a Civil & Structural Engineer • Primary concern are Settlement and Bearing Capacity • Able to safely carry compressive tension Deep foundations are purposed to transfer loads from a structure to the soil and earth which are much further deeper than a shallow foundation works. Deep Foundations are also used when the layer of the soil cannot support the weight of the building, hence the load of the building must has its load transferred and bypassing this layer to a stronger soil beneath the weak layer. Deep foundations are usually extended much beyond shallow foundation and is commonly used on buildings that has a heavy and concentrated load such as a high rise building.

The test load shall be maintained on the pile for at least 48 hours and settlements & data shall be recorded at intervals. The test load would then be unloaded in four equal decrements at one- hour intervals until the full load is removed. Data readings will be made immediately after and before every load is applied or removed. The maximum test load in a Working Load Test (WLT) would be 200% of the working load of a pile.

The floor slab is a semi precast component that includes the lower floor slab reinforcement that is required for structural reason. One Way Slab Grid Slab Two Way Flat Slab Hollow Core Slab Figure 1 Figure 2 Figure 3 Figure 4 Simple support by the side edges only. Structural topping Reinforcing as required. The force is applied on the slab, Slab surface become cylindrical. Shape like square pocket. Flat slab placed directly on the concrete columns. One way slab is a rectangular slab , supported by its two opposite long edge and free of any support along the two opposite edges. If force is applied on the surface, the slab will become curvy as shown in Figure 1. Two way flat slab is a two way reinforcement that usually does not have beams and girders, and the loads are transferred directly to the supporting concrete columns. Hollow core slab is also known as a voided slab, typically used in the construction of floors in multi story apartment building. A waffle slab is a type of slab that have two directional reinforcement of the slab. Giving it the shape of pocket on a slab. A waffle slab gives a substances significantly more structural stability without using a lot of additional materials. Waffle slab is normally used in industrial or commercial building. slab | prepared by Yew Wing Kee
  • 34. page | 34 TYPE OF SLAB (bangi site) INSTALLATION REQUIREMENTS Slab type used: Hollow Core Slab The photo is taken at the construction site where the worker is now installing the hollow core slab. Hollow Core Slab is normally use in the construction of floors for high rise apartment or multi storey building. Compared to other traditional method of construction, hollow core slab are manufacturedusinghighlycustomatedhollowcoremachine, through environment friendly manufacturing process. 1. Hollow Core Slab need to be installed followed by the drawing. 2. Worker need to make sure that all the slab joint widths uniform. 3. If the worker seek that there is a possibility of trapping water in the cores, each core should be tapped near the end to provide drainage. slab | prepared by Yew Wing Kee
  • 35. page | 35 INSTALLATION PROCESS The worker will lift the hollow core slab near the end of the slab, this is due to lifting the slab too far away from the end may caused breakage. Using erection clamp with safety slings for hollow core slab that is width 4’ , when the worker was attaching the clamp to the slab, they need to ensure the clamp is level. Next, they will pull the hollow core slab sling to the adjacent erected slab. Worker will marked the location of slab joints on the bearing area. This will ensure the gauging of proper joint width and not overrun or undercover the prescribed area. After erected the slab, the worker will pull the lifting clamps clear of the grout key after the crane lines are slackened. Therefore, a safe platform was form by hollow core slab, the platform can used by worker to further their work and a space where they can placed their construction tools. Finally, the last step will be pouring concrete in the end of the slabs to integrate them with support. 1 2 3 4 5 6 slab | prepared by Yew Wing Kee

Slabs are best used on level ground and in warm climate. They can be used where ground level is uneven. Most heat energy is lost at the edges of slab. This loss is reduced by using rigid insulation. In some extreme cases, heating ducts can be built into the slab itself. This is very efficient and provides building with an even temperature.

These must all be deeper than the rest of the slabs. After the excavation is done, the corners are relocated. Lines are restrung on batter boards and the corners are plumbed. In the diagram below, the footing forms for two piece slab are made like standard footing or foundation form. The worker have another easier way to construct the floor slab which is using sand to spread evenly over the form area. Install electrical pipes, sleeves for air conditioning piping and wiring . Then two workers will walk on the concrete slab, one worker will placed the concrete and another worker will pull up the wire. This is to ensure the strength of the slab. After that , the workers will start pouring the concrete to covered the form of the slab. They will start pouring concrete from the corner of the form. Finally, when the concrete is fully covered the slab, the worker will wait for it to dry and they will start cleaning up the site . 1 2 3 4 5 slab | prepared by Yew Wing Kee
