1.2 Lot 120, Mukim Lunas, Daerah Kulim, Kedah Darulaman
The Elmina Valley Phase EV1A was
once an oil palm plantation estate
until it was transformed into a
residential area. It is located at
Petaling district which is connected
to the Guthrie Corridor Expressway,
Federal Highway, Kuala Lumpur –
Kuala Selangor Expressway and
North Klang Valley Expressway. The
strategic location of the site meant
that a shorter drive to Kota
Damansara, Shah Alam and the
Subang Airport is made possible.
The residential area consists of 157
terrace units with nature parks as its
recreational area. A man-made
lake was also built in the middle of
the residential area for aesthetic
and recreational purposes. There is
also an amphitheatre provided
within the residential area to act as
a gathering place for the residents.
The project is located at Kulim District, Kedah, Malaysia. It is the closest town to the
Greater Penang in Kedah. As there are quite a huge amount of people living in the
district, rapid development of residential areas occurs around the area to cater the
provide accommodation for the increasing number of citizens. Lot 120, Mukim Lunas,
Daerah Kulim, Kedah Darulaman is one of the residential construction projects that aims
to provide comfortable living place for the public. The project is located near a river as
well as a police and petrol station. The residential area consists of 12 units of single-storey
terrace houses, 28 units of 2-storey terrace houses, 8 units of single-storey semi-detached
houses and 20 units of semi-detached houses.

2.4 Safety Protocols
The safety of personnel working in the construction site of Elmina Valley is taken very
seriously and every safety measures have been carried out to ensure the workers’
safety on site at all times. The Sime Darby Development Department have designated
a green zone in every construction site to provide an area to conduct security checks
on workers as well as visitors to ensure their safety on site. Safety equipment which are
stored in the green zone are also distributed to provide protection to those at site.
Safety signboards, bulletin boards and security booths are present in the green zone.
The safety issued on workers are very strict and they were required to wear helmet, vest
safety boots for normal safety compliance. The workers need to be registered as
verified foreigners and need to have formal permits and passports. Every workers
requires to keep their ID, which is written at the back of the safety helmet for security
and safety measurements. The workers are also required to enter personal code and
hand print in the green zone when entering the construction site.
- Consist of various pinned project information for workers, visitors and other authorised
personnel to refer to.
- Articles on health and safety for construction site personnel to read.
- Posters on safety campaigns are posted on the boards to create awareness among
the construction site personnel.
- Provides emphasis on important reminders and alerts the public on the potential
dangers and risks on the construction site.
- A diagram of the Personal Protective Equipment (PPE) to remind workers of the
required safety equipment when on site.
- Signage of assembly point to indicate the location of the emergency gathering point
during any unforeseen accidents or emergencies.

2.6 Plants and Machinery
2.6.1 Earthmoving and excavating equipment
he selection of the appropriate type and size of construction equipment often affects
the required amount of time and effort and thus the job-site productivity of a project.
It is therefore important for site managers and construction planners to be familiar with
the characteristics of the major types of equipment most commonly used in
construction.
- Earthmoving and excavating equipment are heavy-duty vehicles, designed specially
to execute construction tasks, most frequently involving earthwork operations.
- As they imply the mechanical advantage of a simple machine, the ratio between
input force applied and force exerted is multiplied. Some equipment uses hydraulic
drives as a primary source of motion.
The back-hoe loader can be used for a wide variety of tasks as there are both a
bucket and a shovel attached to it. It is normally used in smaller construction works to
dig shallow excavations and trenches, general grading, mall demolitions as well as
light transportation of building materials
i. Back-hoe Loader
Used to excavate below or above natural surface of ground on which machine rests
and dig pits for basement. It can excavate close range works as they have better
bucket. Excavators can also be used for forestry work, demolition and many more.
ii. Excavator
Compactors are used for
compacting crushed rock as the
base layer underneath concrete or
stone foundations or slabs. The
function of compactors is to
produce higher density soil
mechanically. The basic forces
used in compaction are static
weight, kneading, impact and
vibration. The degree of
compaction that may be achieved
depends on the properties of soil, its
moisture content, the thickness of
the soil layer for compaction and
the method of compaction.
iii. Vibratory soil compactor
Tan Min Chuen 0322938 4

2.6.2 Lifting and erecting equipment
A crane mounted on a truck carrier provides the mobility for this type of crane, these
cranes are able to travel on highways, eliminating the need for special equipment to
transport the crane, usually used in smaller construction to dig shallow excavations
and trenches, general grading, hoist and place materials
Concrete transport trucks (in–transit mixers) are used to transport and mix concrete
while travelling to the construction site. The concrete mixing transport truck maintains
the material's liquid state through agitation, or turning of the drum, until delivery. The
interior of the drum on a concrete mixing truck is fitted with a spiral blade. In one
rotational direction, the concrete is pushed deeper into the drum. This is the direction
the drum is rotated while the concrete is being transported to the building site. This is
known as "charging" the mixer. When the drum rotates in the other direction, the
spiral blade "discharges”, forces the concrete out of the drum.
A device that homogeneously combines cement, aggregate such as sand or gravel,
and water to form concrete. The portable concrete mixer uses a small revolving
drum to mix the components. For smaller jobs, the concrete made at the
construction site has no time lost during its transportation, giving the workers ample
time to use the concrete before it hardens.
Lifting and erecting equipment are machineries that are used to deliver materials
and equipment or lift loads from a place to another vertically and horizontally.
2.6.3 Mixing and grading equipment
Mixing and grading equipment are construction equipment that mix up the materials
and are mainly used to produce concrete by mixing aggregates, water and cement.
i. Truck Mounted Moblie Crane
i. Concrete Transport Truck
ii. Portable Concrete Mixer
A tractor with a fork built in front
to lift heavy objects. It is
commonly used in construction
to move aside or load materials
into or onto another type of
machinery. Another critical
characteristic of the forklift is its
instability. The forklift and load
must be considered a unit with a
continually varying center of
gravity with every movement of
the load. A forklift must never
negotiate a turn at speed with a
raised load, it may combine to
cause a disastrous tip-over
ii. Forklift

2.6.4 Transporting vehicle
Transportation vehicles are heavy vehicles that able to transport materials and
equipment for a long distance. They are usually used to transport materials from the
base to the construction site.
2.6.5 Construction equipment
i. Dump Truck
i. Bar Bending Machine
ii. Truck
Dump trucks are used for transporting loose
material (such as sand, gravel, or dirt) for
construction. A typical dump truck is
equipped with an open-box bed, which is
hinged at the rear and equipped with
hydraulic pistons to lift the front, allowing the
material in the bed to be deposited on the
ground behind the truck at the site of
delivery.
A motor vehicle designed to transport
cargo. Trucks vary greatly in size, power,
and configuration, with the smallest being
mechanically similar to an automobile.
Trucks are usually used to transport plants
such as, generator set, portable concrete
mixer, mobile lighting tower to desire places
on site.
Bar bending machines are used for bending
reinforcement bars and various forms of
round bars.
ii. Bar Cutting Machine
Bar cutting machines are used for cutting
reinforcement bars and various forms of
round bars.
iii. Mobile lighting tower
Mobile lighting towers are used to light up
the construction site at night. And also used
to light up spaces with low light intensity.
iv. Generator Set
A generator set is an electronic device that
supplies electric energy to devices and
machineries on site.

The workers’ accommodation is a composition of large numbers of cabins to
accommodate the workers. The accommodation is constructed using containers
and zinc roofing, which results in the containment of hot air within the living space.
Stairs are provided to allow accessibility to the first floors. In addition to that,
balconies are also present outside of the cabins to allow the workers to hang their
shirts for drying and a car park is also provided for the workers to park their vehicles.

3.2 Preliminary (Service Connection)
3.3 Setting Out
3.3.1 Horizontal Control Technique
Before starting earthwork make sure there are no service lines such as electrical
connections, water supply and drainage connections, telephone lines or others
below ground.
Setting out involves working out the location and extent of the building on site. As
each site is different, contractors should start by establishing the particular
conditions. The process involves the positions and levels of building lines and road
alignments shown on the construction plans to be established on the ground by
various techniques and instruments. Setting out is usually divided into two stages
which is the first stage of setting out and the second stage.
The second stage of setting out continues from the first stage, beginning at the
ground floor slab or road sub-base level. Up to this point, all the control will be
located outside the main construction, for example the pegs defining building
corners, centre lines and so on will have been knocked out during the earth
moving work and only the original control will be undisturbed.
Horizontal control surveys are conducted to coordinate horizontal positional data.
These positions can be referenced by parallels or plane coordinate axes. Because
they are used as a framework for other surveys, these surveys must be precise and
accurate. These surveys provide a network of monuments or points on the ground
that can be used as the control for any other surveying project, such as a
boundary or construction survey. The advantages of using a horizontal control
survey is that lost monuments can be replaced accurately, surveys can be
coordinated, more than one network station can provide a check to the work,
and a reduction in the cost of the project can be achieved. Most horizontals
should (and will) be connected to the control network.
3.3.2 Vertical Control Technique
A vertical control survey determines elevation with respect to sea level. These
surveys are also used as a benchmark upon which other surveys are based and
high degree of accuracy is required. These surveys are useful for tidal boundary
surveys, route surveys, construction surveys and topographic surveys. In a vertical
control system, at least two permanent benchmarks should be used, but the
number of benchmarks required may increase depending upon the needs and
complexity of the project. These projects are needed for the construction of water
and sewer systems, highways, bridges, drains, and other major town or city
infrastructure. These surveys can be done alone, but are often done in conjunction
with a horizontal control survey.
Foundation
In practice, the first stage of setting out involves the use of
the horizontal and vertical control techniques. The purpose
of this stage is to locate boundaries of the work in their
correct position on the ground surface and to define the
major elements. In order to do this, horizontal and vertical
control points must be established on the site.
Figure beside shows the setting out process before the
foundations were constructed. Timber frames were first
fixed on site to allow strings to be tied and to determine the
location in which the walls will be erected.

3.3.3 Method used in setting out
3.3.4 Setting out of pipelines
3.3.5 Optical level, optical square and Theodolite construction
3.3.6 Sight Rails
Baselines are located by setting out their terminals. If co-ordinated they would be
set out from a traverse. The length of the baseline can be measured and
compared with its compound values. Alternatively, the baseline could be set out
with reference to other detail such as road centrelines, existing buildings, etc.
Again it is necessary to check the measured length against that given on the
drawings. Usually for the purpose of measuring angles.
Offset pegs are normally used in the form of baselines or grids or as horizontal
control points used to establish the design of the proposed structure. The offset
pegs are only used when the original pegs are unable to be installed.
A temporary benchmark (TBM) is a fixed point with a known elevation used for level
control during construction works and surveys. Nails in road seals, or marks on kerb &
channel are commonly used as temporary benchmarks
A Theodolite is an instrument for measuring both
horizontal and vertical angles, as used in triangulation
networks, and geo-location work. Other specialized
purposes make Theodolites ideal for shop and factory
floor layout of tools and fixtures. They also work well for
layout for the construction of concrete slabs,
landscaping, and road design.
A series of rails set with a surveying instrument, and used to check the vertical
alignment of a pipe in a trench.
Pipelines are to be checked on chainage, this could be every few pipes, for small
diameter and every pipe for large diameter. The pipelines must be tested in
accordance with the contract specification, any air or water testing of line should be
done by an experienced person.

3.4.2 Benchmark
The purpose of this section is to establish uniform practices to be followed for
removal of trees and stumps. Where such removals are set up on a lump sum
basis, varying interpretations as to the extent of removal are possible. It is
necessary to exercise judgment in the administration of this item to accomplish
the desired results.
The desired level was marked in a permanent
place. This mark will be needed throughout the
project duration.

3.4.3 Side-slope in excavation
During earth excavation check that
slope is maintained in side-soil.
Dump trucks are normally used instead of scrapers
when the soil is being excavated by loaders. Most
dump trucks can travel over public highways, and
move faster than scrapers.
Figure 3.6 Soil compactor are used in the compaction of soils after grading.
3.4.4 Base soil
3.4.5 Excavation area
3.4.6 Backfill
3.4.7 Compaction
Check the base soil, on which building's foundation will rest, is hard enough. You
may consult geotechnical engineer that the base soil is perfect for further work
execution.
Compaction reduces the volume of air space in the soil. This compaction
increases the dry unit weight and strength of the soil to better support structures.
This is a very important step.
- Check backfill is being done after ending the shutter removal period of footing.
- Backfilling material: Try to backfill with the excavated soil. And check the
backfilling material is free from large lumps, organic or any other foreign
materials. Check all shuttering materials are removed before backfilling.
- Backfilling should be done evenly on all sides. Check that is being done
properly.
- Backfilling should be done layer by layer. Each layer shouldn't exceed 6 inch
thickness. And each layer should be compacted to maximum dry density of soil.
Check those are being done properly.
- Ensure that the excavation area is extended beyond the foundation of
buildings for easy circulation of movement during work execution.
- Cleaning of foundation bed: Check that loose and displaced materials are
cleaned from the foundation bed.

Construction process of reinforced concrete pad footings
1. The position of footings are set out according to the plan dimensions
2. Cement powder is then used to mark the size of footings
3. The earth was excavated to the required depth and dimensions by using an excavator
4. Hardcore was then placed on top of the excavated earth and it should be used in not less than 150mm thick but no greater than 600mm in selected aggregate. The
hardcore is then compacted down in layers using a plate compactor
5. A formwork is then placed according to the set dimensions
6. Studs are then added to prevent the falling of the formwork.
7. Bracing is then used to hold the formwork in position. This is to ensure that the formwork is able to withstand the horizontal forces of the concrete when it is poured.
8. A lean concrete mixture is then added and levelled. Its purpose is to provide an even surface for the foundation concrete. It is also used to prevent direct contact of
foundation concrete with soil
9. Workers then start to arrange the reinforced concrete bars to form reinforced concrete cages
10. After the reinforced concrete cages are completed, the workers place the reinforced concrete cage into the formwork
11. The reinforced concrete cage is then placed on top of the spacer blocks. The spacer blocks are used to maintain the reinforcement in the proper position. Concrete
spacers can help prevent corrosion, protect them from fire for a certain length of time and help to provide a proper transfer of stresses from concrete to steel rebars.
12. After placing the rebar cages in the formwork, the reinforcements were erected for stump and add more ties to the formwork
13. Eventhough concrete is durable and has a very good compression strength, it has a weak tension strength. As such, reinforcements are used to carry tensile load of
structures
14. A starter bar is tied to the reinforcement to allow the reinforcement of the column to be tied onto the reinforcement steel bars.
15. The position of starter bars were fixed before the concrete was poured into the formwork.
16. Concrete is poured into the formwork and adequate compaction is ensured by using vibrators or self-compacting concrete. The concrete is allowed to cure before
proceeding to the next stage of construction
17. Set, curing and hardening and when the concrete gains sufficient strength, the formwork is dismantled, and thus the reinforced concrete pad footing is completed

4.2.1 Shallow foundation
i. Strip Footing
ii. Pad Footing
Types of pad foundation design
Types Of Strip Footing
The Foundation is the substructure and the bottommost section of a building. It is
constructed halfway or completely below the surface of the ground.
- They spread the load over a larger area at an equal rate so that the burden on
the foundation soil does not exceed the safe bearing capacity.
- Foundations shift the unequal load of the superstructure equally to the sub soil
hence it minimizes the differential settlement that occurs.
- Foundations offer the stability against, voids formed by scouring underground
water and the burrowing animals.
- Foundations prevent the structures from sliding above the sloping ground.
- Foundations offer a leveled and balanced surface for the construction of the
superstructure.
- Transfer load directly on to the hard layer of soil.
- Maximum depth of shallow foundations is 3 meter.
- Provides support for light loads when the soil is in stable condition and with
adequate bearing capacity
Uniformly distributes load
(Load is distributed evenly
along the entire structure)
Mass concrete
for stell columns
Reinforced concrete
with sloping upper
suface
Point loads (Load is
condense at individual
points)
- Strip footing is the most common and
widely used foundation; it is basically a
strip of concrete placed in a long
narrow ditch.
- It usually supports the load bearing
structure or wall without columns and
beams. (e.g.: Brick wall)
- The depth of the foundation is
roughly 1 meter, while the width of the
foundation depends on the condition
of soil and the load. As an example,
the weaker soil requires a wider strip
foundation.
- The thickness of the strips must be at
least 150mm.
- Pad footings are individual or isolated
foundations to support the columns of the
building.
- Pad footings are a form of disseminate
foundation, which is made up by rectangular,
square, or sometimes circular concrete ‘pads’
that support localized single-point loads like
structural columns, groups of columns or framed
structures.
- Pad footings are usually used when the load of
the building is carried by the columns.
- It uses concrete pad at the base with concrete
columns or steel columns attach by captive
bolts.

ii. Raft Footing iv. Cantilever/ Strap footing
Types Of Raft Footing
Types of cantilever (plan to elevation)
- Raft footing are similar to slab floating on top
of the soil.
- It is usually used on soft natural ground
- It used to cover the whole base area of a
building and extend beyond it; this is to
prevent differential settlement which can
cause foundation failure on a building.
- It supports the walls and acts as floor slab
- The detail of edge of the foundation is
decided by the nature of the load applied on
it.
- A form of concrete apron will extend from
the edge of the foundation to act as
protection from erosion
- Independent footings of two columns are connected by a beam.
- The beam is used to help transfer the weight of the loaded column footing to
adjacent footing.
- The strap beam is not in contact with the soil, and thus does not transfer any pressure
to the soil.

ii. Pile Foundation
End Bearing Pile Friction Pile
- Deep foundations function to transfer the load of the building to a deeper layer of
dense sand and gravel below the soil.
- The depth of the foundation is more than 3 meters
- Deep foundations are used for heavy load when the soil is unstable and
inadequate bearing capacity.
- A pile is fundamentally a long piece of a strong material penetrating into the
ground to act as a steady support for structures built above the ground.
- Piles are used when the soil strata could not handle the heavy load from the
structure.
- Pile foundations may be classified as either End bearing or Friction piles, according
to the manner in which the pile loads are resisted.
- The shafts of the piles act as
columns carrying the loads
through the covering inferior
subsoils to firm strata into which
the pile toe has penetrated.
- This can be rock strata or a layer
of firm sand or crushed stone
which has been compress by the
displacement and vibration
encountered during the driving.
- Any foundation imposed on the ground will
form a pressure which spreads out to form a
pressure bulb.
- If a suitable load bearing strata cannot be
discover at a fitting level, especially in stiff clay
soils, it is possible to use a pile to carry this
pressure bulb to a bottom level where a higher
bearing capacity is found.
- The friction or floating pile is mainly supported
by adhesion or friction action of the soil around
the perimeter of the pile shaft.
- Consists of a cylindrical column of large diameter to sustain and transmit large
super-imposed loads to the firm strata below.
- Often used in the construction of bridge piers & other structures that requires
foundation beneath rivers & other bodies of water.
- Preferred in a location where the top strata consists of decomposed rock overlying
a strata of sound rock.

Types of pile
Displacement piles
Large displacement pile
Precast reinforced concrete piles
The large displacement pile is the pile which is solid and with large x-section area
and hence compress bigger amount of soil under the ground.
For non-displacement pile, a void is form on the ground by excavation. The void is
then filled with concrete. The side of the void can be supported or unsupported
depend on the situation.
Small displacement pile
non- displacement pile
The small displacement pile is the pile with less x-section area and compress or
displaces less amount of soil under the ground.
Eg. RC pile
Eg. Bore pile
Eg. H-pile
- The precast reinforced concrete piles are piles which were
moulded in circular, square, triangular or octagonal form.
- They are casted and cured in a casting yard and then
transported to the site for installation
- They provide high strength and resistance to decay.
- They are heavy, and because of their brittleness and low
tensile strength, extra care in handling and driving is required.
- Cutting of the precast reinforced concrete piles requires the
use of concrete cutter, pneumatic hammers, cutting torches,
etc

Type of Steel preformed piles
Piling proccess
For non-displacement pile, a void is form on the ground by excavation. The void is
then filled with concrete. The side of the void can be supported or unsupported
depend on the situation.
- Driven in situ piles are those piles which are cast in place inside the ground.
- The pile shaft is formed by using a steel tube which is either top driven or driven
with an internal drop hammer working on a plug of dry concrete/gravel as in
Frankipiles.
- This method can be used to build the piles up to 610mm.
- Since the cast-in-situ piles is not subjected to handling or driving pressure, it is not
essential to reinforce the pile in ordinary cases or in places where the pile is
completely flooded in the soil. Reinforcements are only provided when the pile
acts as a column and is subjected to inclined forces.
- Cast- in-situ piles can be differentiated into two types. In one the metal shell of
the pile is permanently left in place lining the ground along with the core while in
the other type, the outer shell is withdrawn.
- Composite piles are piles which are made from two different materials that are
driven one over the other, so as to allow them to act together to perform the
function of a single pile.
- One advantage of this type of pile is the ability to adopt of the fine qualities of
both the materials
- They are economical as they utilize the great erosion resistance characteristics of
one material with the cheapness or strength of the other.

Drop Weight
Bore Pile
Step 1
- The crane is used to transport the piles to a particular area that has been
excavated.
- The piles are all delivered cautiously as they are fragile.
Step 2
- The pile is tied up to its lifting lug and is prepared for hammering.
Step 3
- Before the hammering procedure begins, they are all located accordingly to
be driven into the ground
Step 4
- Hammering process started
- The drop hammer is used to drive the pile
- The subsoil around the pile shaft is displaced
- The pile driving to its maximum depth until it cannot be driven
- Bored pile is a cast in situ concrete pile which has to be casted on the
construction site. Contrary to displacement piles, the soil has to be excavated and
the resulting hole will be filled with concrete or a precast concrete pile which will
be dropped into the hole and grouted in. As such, no displacement of soil will
occur.
- Bored piling machine which was used to cast the bored pile has specifically
designed drilling tools, buckets and grabs and the machines are used to remove
the soil and rock.
- Casting of bored piles have to be done by specialised bored piling contractors
- The length, width, depth and style of bored pile foundations depends on the
type of the project and the surrounding environment.
- It produces less vibration and reduces the noise level compare to other piling
system.
- It causes less disruption to adjacent soil
- Bored piles are usually used for tall buildings or huge industrial complexes, in
which a foundation that can carry thousand tons of loads is needed, most
probably in unstable or difficult soil conditions.

4.0 Foundation
4.1 Foundation type and construction process (from site visit)
Residential houses constructed at Elmina Valley Phase EV1A are 2-storey terrace houses. After conducting our site visit, we’ve learnt that the type of foundation used to
construct the houses are classified as reinforced concrete pad foundations. Pad foundations are individual or isolated foundations which are used to support localised loads
such as columns.
Pad footings are one of the most simple and common types of foundations and they are used when the load of the building is carried by columns which sit on top of square
or rectangular pads of concrete.

5.1 Super Structure (from site visit)
5.1.1 Ground Beam
5.1.2 Slabs
- Ground beams are reinforced concrete beams which support walls, joists and other structures near ground level.
- Ground beams are either standing directly upon the ground or supported at both ends by piers.
Ground floor slabs are reinforced concrete blockworks situated on the ground which supports walls. These concrete slabs are a common structural element of modern
buildings. It is normally horizontal and has a smaller thickness if compared to its span. It is usually furnished using a flat and strong surface in reinforced concrete construction.

5.1.3 Beams and columns
Photos above shows the fisrt floor slab in our site
Similar to ground floor slabs, first floor slabs are reinforced concrete blockworks
supporting walls of the first floor of the building. However, they are not
constructed on the ground, but are supported by a series of columns and walls.
The types of first floor slabs found at Elmina Valley Phase EV1A are two way slabs
with beams.
Continuous beams are supported on more than two supports. It is more economical
for any span lengths and they are several beam supports at the bottom.
Simply supported beams are supported freely at the two ends on walls / columns.
Most of the construction process of first floor slabs are the same as ground floor
slabs, which include:
1. Building formwork.
2. Install reinforce bar.
3. Pouring concrete.
4. Consolidation. (Process of uniting)
5. Finishing.
6. Curing
Beams are structures which are rectangular in cross-section that carry the
weight of the floor slab or the roof slab and they transfer all the loads including
its self-weight to the columns or walls.
There are two types of beams found on the 2-storey link houses of Elmina Valley
Phase EV 1A, namely continuous beams and simply supported beams.
Most of the construction process of beams is similar to ground beams.
1. The props/supports are erected.
2. The soffit of beams are fixed.
3. The formwork for the side of beams are constructed
4. Steel reinforcements are placed inside the formworks.
5. The formwork, which is completed with struts, are constructed to the side of beams

Construction process of beams
Beams

Columns
A columns is a vertical structural member that functions to transmit the load from
ceiling/roof slabs and beams, including its self-weight to the foundation. Columns
situated on the ground floor are a continuation of foundations, and, in the case of
Elmina Valley Phase EV 1A, the columns are a continuation of the reinforced
concrete pad footings.
1. During the construction of the reinforced concrete pad footings, reinforcements
were added on top of the reinforced concrete cages to create stumps. Concrete
will be poured into the formwork and the formwork will be removed once the
foundation is completed.
2. Once the ground beams and ground floor slabs are completed, the
reinforcements will be extended to construct the columns.
3. The formworks for the concrete columns are then fixed and concrete will be
poured into the formworks. The formworks will be removed after the concrete has
cured.
5. Concrete will then be poured into the fixed formworks to construct the columns.
Concrete buckets as well as triangular-shaped wooden planes were used to pour
small volumes of concrete into the wooden frames when constructing the
columns.
6. Once the concrete has cured, the formworks will be removed and the columns
are completed.
4. A similar process will take place after the columns on the first floor is completed.
The reinforcements will be extended, and after the beams and first floor slab are
completed, formworks will then be fixed.
The image shows the columns found on site.
Completed columns on the ground floor support

Walls found in the 2-storey terrace houses of Elmina Valley Phase EV1A can be
categorized as masonry walls, and in specific, brick walls. There are two types of
bricks which are used for the construction of the houses in Elmina Valley Phase
EV1A, namely red clay brick and cement sand bricks.
- Sime Darby Development’s rules and regulations states that the party walls of
residential houses are to be constructed out of red clay bricks. As such, party walls
of the 2-storey terrace houses were built using red clay bricks.
- The bricks were laid using the English Bond method.
- Cement sand brick is used to construct both internal and external walls of the
2-storey terrace houses of Elmina Valley Phase EV 1A.
- Red clay bricks provide thermal & acoustic insulation .
- Red clay bricks do not require any maintenance cost.
- The high compressive strength of fired clay bricks has been exploited for millennia
to build structures ranging from single-storey huts to massive public buildings and
enormous bridges and viaducts.
- The cost of red clay bricks brick is higher compare to other bricks like cement sand
brick or concrete brick.
The photo shows the red clay brick wall found on site.
The photo shows the cement sand brick wall found on site.
Advantages of Red clay brick wall
- The cost of cement sand bricks are lower compared to red clay bricks as they can
be easily made in a short period of time.
- Cement sand bricks provide good sound insulation.
Advantages of Cement sand brick wall
Disadvantages of Red clay brick wall
- Cement sand bricks are not fire proof bricks and it cannot withstand high
temperature. The bricks will crack if they come in contact with high temperature
like fire.
- Cement sand bricks are also much heavier than red clay brick.

The staircase found at the 2-storey terrace houses of Elmina Valley Phase EV 1A
can be classified as concrete straight staircase.
- The run of the steps was then measured by finding the distance between the
frontmost and backmost part of the stairs.
- The width of the stairs was measured by calculating the distance between the
leftmost and rightmost bounds of the planned steps of the stairs.
2. Building and Assembling Formwork:
- The formwork was made by using plywood or framing timber. The side forms are
cut according to the tread and riser calculations.
3. Reinforcement
- Reinforcement bars are carefully bent at the necessary height and length and
positioned into the formwork.
4. Preparing Concrete:
- Sufficient and well mixed mortar was prepared using portable cement mixer.
5. Pouring concrete:
- The process started from the bottom and the concrete was poured one step at
a time. The mortars are spreaded evenly and spade was used to remove the
trapped air bubbles.
1. Measure the dimensions of your stairs:
- Firstly, the total rise of the stairs, which can be found
by measuring the total height from the planned
base to the higher level/floor, was measured.
The images above shows the timber formworks which were fixed for the construction of the staircase.

will be installed.
- The position of the railings were marked
- Pilot holes were drilled into the staircase on the marks made.
- The railings were placed into the pilot holes.
- Cement was then poured into the holes to fix the handrails.

Columns
A vertical structural member that functions to transmit the load from ceiling/roof
slabs and beams, including its self-weight to the foundation.

Types of fail modes of columns
- A wall is a structure that defines an area, carries a load, or provides shelter or
security.
- They are part of the 3 planes in architecture (along with 2 other planes, which
are the overhead (roof) plane and the base (floor) plane that defines the 3
dimensional volume of mass and space.
- The purpose of walls in buildings are to support roofs, floors and ceilings, enclose
a space as part of the building envelope, to give buildings their form along with
roofs and to provide shelter and security.
Function of walls
- Thermal Insulation
- To provide protection from natural elements such as weather and animal threats
- To divide and separate the areas within the building to create interior spaces.
- Act as sound barriers
- As fire walls to attenuate the spread of fire from one building unit to another.
- To improve the building appearance.
- To provide privacy
Strength and stability of walls
Resistance to:
- Stresses set up by its own weight
- Superimposed loads
- Lateral pressure (for example, wind)
- Overturning by lateral force
- Buckling caused by excessive slenderness
i. Long Column or Slender:
Type of column that fails
by elastic buckling,
where it occurs at
compressive stresses
within the elastic ranges
called long column.
ii. Short Column: A
very stocky column
which will not fail by
elastic buckling. It will
crush and squash due
to general yielding
and compressive
stresses
Intermediate columns:
It will fail by inelastic
buckling when a
localized yielding
occurs. This will be
initiated at some point
of weakness and
crookedness.
Construction process of concrete columns
1. Fix the reinforcement
bar for the concrete
column.
2. Fix the formwork
for the concrete
column.
3. Pour concrete
and wait for it to be
cured then remove
the formwork.
5.2.3 Walls

Types of walls
- Load bearing / Non Load Bearing
- External / Internal
Materials of walls
A. Concrete Walls
B. Masonry Walls
C. Dry Walls
D. Glass Walls
E. Curtain Wall SystemLoad bearing walls carry and distribute the load of a building from roof and floor
from above (and lateral load) to the structures or foundations situated below the
building.
A load bearing wall is part of the structure of the building as it holds the building
up. They are usually made of concrete, brick or block, hard materials which have
to stand the test of time and heavy weights.
- Pre Cast Concrete Wall
- Retaining Wall
- Masonry Wall
- Pre Panelized Load Bearing Metal Stud Walls
- Engineering Brick Wall (115mm, 225mm)
- Stone Wall
As the height of the building increases, required thickness of walls and resulting
stress on foundation will also increase and cause it to be uneconomical.
Buildings with cast-in-situ reinforced concrete shear walls are widespread in
many earthquake-prone countries and regions. Shear wall buildings are
usually regular in plan and in elevation and shear walls are the main vertical
structural elements of the buildings with a dual role of resisting both the gravity
and lateral loads. Wall thickness varies from 140 mm to 500 mm, depending on
the number of stories, building age, and thermal insulation.
Reinforcement requirements are based on building code requirements
specific for each country. In general, the wall reinforcement consists of two
layers of distributed reinforce requirements.
Characteristics
- Usually used as load bearing walls
- Texture and appearance can be controlled by the use of formworks admixtures
and additives formworks, admixtures and additives
- Often used in high-rise buildings in Malaysia
- Often used in government projects in Malaysia, as part of the industrialized
building system (IBS)
- Offers greater speed of construction and control of quality
i. Cast in-situ reinforced concrete shear wall systems
ii. Pre-cast concrete wall systems
A non-load bearing wall is only a partition that divides the various spaces of a
building to create rooms. These walls do not carry any structural load except for
their self-weights and wind load which acts on the structure (for example,
column, slab or beam).

Precast concrete wall systems can be comprised of a variety of shapes, and wall
types. Typically, precast concrete wall systems fall into three basic categories:
solid, sandwich and thin-shell. These can be penalized and erected in either a
horizontal or vertical position and used on all types of structures from residential to
commercial, institutional to industrial. Wall panels can be designed as
nonloadbearing or loadbearing, carrying floor and roof loads, as well as lateral
loads.
Construction process of cast in-situ reinforced concrete shear wall systems using
timber formworks
Advantage of using shear wall method of construction
- Speed in erecting and dismantling forms
- Good appearance
- Greater control of accuracy and workmanship
- Creates a smooth, high quality finish capable of receiving direct decoration
with the minimum of preparation
- Tornadoes, hurricanes and earthquake resistance
Solid Walls
Solid wall panel simply refers to walls being made of solid concrete as opposed to
including integral insulation. These wall systems require some form of insulation
and an interior wall/finishing system to complete the building enclosures.
Sandwich Walls
Insulated sandwich wall panels can be strictly
architectural, strictly structural, or a combination of
both. The difference between typical panels and
insulated sandwich wall panels is that the latter are cast
with rigid insulation "sandwiched" between two layers, or
wythes, of concrete. The insulation thickness can vary to
create the desired thermal insulating property ("R"
value) for the wall.
The structural behavior is either:
- Composite in which the wythes are connected using ties through the insulation
that fully transfer loads. The structural performance is then based on the full
thickness of the panel
- Non-Composite in which the wythes are connected using ties through the
insulation, which limits performance to the individual capacities of each wythe.
Thin-Shell and GFRC
Thin-shell wall panels consist of a thin, outer-wythe of
concrete typically ranging between 1.5 and 3 inches in
thickness. This is connected to a "back-up" system, usually
constructed of steel framing or studs, or sometimes
concrete. The back-up system is what connects the wall
panel to the structural system of the building and often
provides the furring for interior finishes, such as drywall to
be attached. Many of these systems can also
incorporate a layer of rigid insulation between the
exterior wythe of concrete and the back-up system.
Benefits of Precast Concrete Wall Panels
- The sandwich construction technique used with the precast concrete walls
provides increased stability and improved sound insulation, as well as greater
protection from potential hazards such as fires.
- Precast concrete panels also provide energy-saving advantages. Because the
concrete wall panels are separated by a layer of thermal insulation, the precast
concrete wall panel system results in enhanced energy performance, which can
help to lower overall costs.
- Superior strength and durability
- Provides excellent protection against impacts from explosions, vehicles and
projectiles
- Ease of installation

Plaster and skim coat
- Skim coating is the process of applying a layer of muddy plaster compound to
rough or damaged ceilings and walls to either smooth or repair them.
- Plastering should be done after curing on the brick masonry.

C. Dry wall/ stud framing system
Partition board wall system
Drywall is a construction material used to create walls and ceilings. It's also used to
create many design features, including eaves, arches and other architectural
specialties. It's quick and easy to install, incredibly durable, and requires only
simple repairs when damaged. In the commercial building world, drywall is used
to wrap columns to conceal steel beams and is an easy and inexpensive way to
top off masonry walls above ceilings. Drywall is also used to add fire resistance at
walls and ceilings, containing the spread of fire so people can evacuate safely
during an emergency.
Characteristics
1. Non-load bearing
2. Relatively simple and easy to be installed
3. Good light and fire insulating properties as it is an ablative material
4. Good sound and thermal insulation properties. The sound and thermal
insulation properties can be improved by the addition of mineral fibre insulation
5. Type of partition board and stud backing system can be varied to suit
different requirements
6. Susceptible to water damage and moulding
7. Susceptible to damage by external forces as it is hollow
Installation process of drywall
1. Estimate the number of drywall sheets required to cover the wall.
2. Cutting

Screw
5. Wait for 24 hours for the mud to dry to begin sanding.
6. Use a pole sander and 120-grit sandpaper to lightly sand the mud you applied
earlier. You've finished sanding when you can't see any tape or mud bulges on
the walls' surface, and when a level applied to the wall shows it is smooth and
even. Wear a mask and goggles while sanding to prevent damage to eyes and
lungs.
3. Hanging
4. Finishing
Framing system of drywall
Start attaching your drywall sheets to the wood or
metal studs used to frame your space. You should
hang sheets horizontally when working with wood
studs, while metal studs work better with vertical
installations. This is because wood studs are more
likely to warp and deflect over time. Hanging the
sheet horizontally allows each sheet to be in
contact with more studs and helps minimize
deflection. Generally speaking, it can be more
difficult to screw into metal studs. When using
wood studs, you should also apply a drywall
adhesive to the face of the studs before hanging
your drywall in order to further minimize
deflection. To attach the drywall to the studs, use
a screw gun and drywall screws, making sure you
hit the studs. Screws should be placed about
every four inches.
Finally, you'll tape, sand and finish the drywall. This
involves applying three layers of mud, one layer
of drywall tape, and a whole lot of sandpaper.
First, use a 6-inch finishing knife to spread joint
compound along each seam. This first layer is
called the tape coat, and should be about four
inches wide, centered on the joints in your drywall
sheets. Next, apply drywall tape along the joints.
The mud you applied will hold it in place. Your
second coat of mud is called your block coat.
Use your 6-inch finish knife to apply a second coat
of mud on top of your drywall tape. Use just
enough to seal the drywall tape in place. The final
coat is called the skim coat. A 10-or 12-inch knife
should be used to apply a third coat of mud. Take
your time on this coat to spread the mud thinly
away from the seams to provide a smooth, level
surface.

Insallation of partition

A structural glass wall is made up of tempered glass
sheets suspended from special clamps, or spider
fittings. These fittings are stabilized against wind
pressure by perpendicular stiffeners and/ or cables
and carry the loads of the glass. Structural glass walls
overcome the restrictions of conventional frames to
provide the ultimate all glass façade.

Stick systems consist of the vertical curtain wall frame
(mullions), horizontal curtain wall frames (transoms),
glass or opaque panels that are installed and
connected piece by piece. These parts are usually
fabricated and shipped to the job site for installation.
It has the advantage that it is economical and the
construction sequence is flexible. Disadvantages are
the lengthy installation time and high dependence
on site workmanship to ensure acceptable quality.
Composite panel walling system
There are a wide range of possible infill panels for curtain wall systems, including:
- Vision glass (which may be double or triple glazed, may include low-e coatings,
reflective coatings and so on).
- Spandrel (non-vision) glass.
- Aluminium or other metals.
- Stone veneer.
- Fibre-reinforced plastic (FRP).
- Louvres or vents.
Stick systems

1. Straight staircase
Composite panel walling system
Panels are often composites, with the facing materials bonded to, or 'sandwiching'
insulation. Frame and panel designs are very complex, as they need to perform
multiple functions, such as:
- Transferring loads back to the primary structure of the building.
- Providing thermal insulation and avoiding cold bridging and condensation.
- Providing fire, smoke and acoustic separation. This is particularly difficult at joints
between the curtain wall system and interior walls and floors.
- Creating a barrier to water penetration.
- Accommodating differential movement and deflection.
- Preventing panels from falling out of the frame.
- Allowing for opening windows.
- Preventing the accumulation of dirt.
Construction process of concrete straight staircase:
1. Measure the dimensions of your stairs:
- Firstly, the total rise of the stairs, which can be found by measuring the total height
from the planned base to the higher level/floor, has to be measured
- The run of the steps was then measured by finding the distance between the
frontmost and backmost part of the stairs.
- The width of the stairs was measured by calculating the distance between the
leftmost and rightmost bounds of the planned steps of the stairs.
Aluminium framing
Aluminium framing is used for the vast majority of
curtain walling applications, primarily for its excellent
strength to weight ratio and its ability to be extruded
in complex shapes. Aluminium is 66% lighter than
steel, as such, it is also far less susceptible to brittle
fractures.
Types of staircase
A staircase is a system of steps by which people and objects may pass from one
level of a building to another.

4. Double quarter
landing staircase
2. Quarter landing staircase 3. Half landing staircase
5. Winder landing staircase 6. Double winder
landing staircase
7. Spiral sraircase 5. Circular staircase

2. Building and Assembling Formwork:
- The formwork can be made by using plywood or framing timber. The side forms
are cut according to the tread and riser calculations.
3. Reinforcement
- Reinforcement bars are carefully bent at the necessary height and length and
positioned into the formwork.
4. Preparing Concrete:
- Produce sufficient and well mixed mortar with portable cement mixer.
5. Pouring concrete:
• Start from the bottom and pour one step at a time. Make sure the mortars are
spreaded evenly. A spade should be used to remove the trapped air bubbles.
6. Add finishing:
- Use a simple wood float to clean and smooth the surface of the mortar.
7. Curing:
- Spray the steps with curing compound and cover it with burlap. Once the
concrete has hardened for a week, the plywood formwork can then be removed.
8. Installing the handrails:
- The stair railings were positioned onto the staircase at the location in which they
will be installed.
- The position of the railings were marked
- Pilot holes were drilled into the staircase on the marks made.
- The railings were placed into the pilot holes.
- Cement was then poured into the holes to fix the handrails.

6.0 Doors and Windows
6.1 Doors
- Doors and doorways provide access from the outside into the interior of a
building as well as to act as a passage between interior spaces.
- Doorways should be large enough for ease of movement and to accommodate
movement of furnishings and equipment.
- All doors should be evaluated for their ease of operation, durability under
anticipated frequency of use, security provisions as well as light, ventilation and
views that are offered by them.
- Door frames used in the construction of the 2-storey terrace houses of Elmina
Valley Phase EV1A are generally aluminium door frames

Advantages of aluminium door frames
- Slim profile
- Durable
- Narrow sight lines
- Low maintenance
- Light yet strong
- Compared with vinyl, fiberglass and wood frames, aluminium conducts heat
and cold the least well
- Windows are key architectural elements that provide a bridge
between the inside and the outside by:
i. Admitting light
ii. Controlling ventilation
iii. Influencing thermal comfort.
- As such, the form and position of windows are key aspects of internal
design.
1. The location of the
doors are measured
and marked. A few
layers of bricks are then
placed beside the
markings.
4. For timber door frame: The
wall is plastered and the main
frame is installed. For aluminum
door frame: Mortar is filled in the
space between the gap and
masonry wall before the wall is
plastered.
2. The door frame is inserted
into the marked position.
The jamb of the door is
nailed into the masonry
wall for support. Bricks are
then continued to be laid.
3. Pre-cast concrete

There are two types of windows available in the 2-storey terrace
houses of Elmina Valley Phase EV 1A, namely up hang windows and
casement windows.
- Up hang windows are hinged at the top and swing
outward from the bottom. They glide open and shut with
the turn of one easy-to-reach handle.
- Up hang windows are often placed above or below
other windows to add architectural interest, light and
ventilation to a room while keeping the rain out.
- Up hang windows are often used in combination with
large stationary windows to provide a constant views and
air flow.
Advantages of up hang windows:
- Versatility: Due to the variety of styling options and the
ability to be installed higher than other types of windows,
up hang windows provide greater flexibility in designing
the décor of a building.
- Weather-proof: Up hang windows open out from the top
and provide protection from the rain when opened. They
allows little to no leakage from rain when the windows are
opened, and as such the user can enjoy fresh air even
when the weather is bad.
- Privacy: Up hang windows can be installed higher than
various types of windows. As such, they are able to
provide natural light and ventilation without
compromising the user’s privacy.

Construction process of windows

Casement windows are windows that are hinged on the side and the sash opens horizontally opposite the hinge. This type of
window allows for full ventilation from top to bottom of the window opening and the extended sash can catch the breeze and
direct it into the house for better air flow.
Advantages:
- Wide openings: Casement windows open completely, allowing a nice breeze into your home
- Superior Security: Locks on casement windows are embedded into the frame. This provides enhanced safety and security.
-Easy operation: Casement windows open easily with a crank, making them ideal for hard to reach areas.

Summary
In conclusion, this project really played its part in allowing students to experience,
document and analyse the construction process through their own eyes. Through
this project, students were able to conduct their own site visit to their chosen
construction site and to fully understand the sequence and coordination of
construction at site. The site visit conducted proved to be an important learning
process for architecture students as practical site visits conducted were able to
allow students to have a clearer understanding of the topics which were covered in
lectures. The exposure of students to construction methods and technologies in
relation to their respective site contexts were able to allow students to broaden their
horizons and to demonstrate their understanding and knowledge of the construction
process in a systematic and professional manner.
For our group, we conducted two site visits respectively. We conducted our first site
visit to Elmina Valley Phase EV1A. Residential buildings built on site are 2-storey
terrace houses and we were able to observe, experience and document several
aspects of the construction process on site, namely site and safety, plants and
machineries, site layout, foundation, superstructures, doors and windows as well as
roofs. Through our site visit, we’ve learnt that site and safety plays a huge role in the
construction site as every safety measures were carried out to ensure the workers’
safety on site at all times. Moreover, we were able to personally observe and
document the different plants and machineries used to construct the 2 storey
terrace houses on site. Plants and machineries were further divided into various
categories, namely earthmoving and excavating equipment, lifting and erecting
equipment, mixing and grading equipment, transporting vehicles, construction
equipment and many more. Moreover, we’ve also learned that a well-planned site
layout is able to increase the productivity of the construction process. A well
planned and organised construction site like Elmina Valley Phase EV1A is able to
ensure a smooth transition from one location to another within the site, avoiding
unnecessary injuries and directing workers to their respective working zones
efficiently. The type of foundation available on site is shallow foundation, and
specifically reinforced concrete pad footings. In addition to that, after conducting
our site visit, we were able to understand the complete construction process for the
superstructures. After the foundations were constructed, the reinforcements will be
extended for the construction of columns. Ground beams will be constructed on top
of foundations and this process will be flowed by the construction of ground floor
slabs. Columns and beams will later be constructed and after the framework of the
entire building is completed, walls will be erected to enclose the spaces. The walls
found on site are masonry walls, namely red clay brick walls and cement sand brick
walls. Roofs present on site are generally gable roofs and they are easily recognized
by their triangular shapes.
In addition to that, we’ve conducted our second site visit to Lot 120, Mukim Lunas,
Daerah Kulim, Kedah Darulaman to obtain an understanding of the process of
setting out and earth works. As Lot 120, Mukim Lunas, Daerah Kulim, Kedah
Darulaman is a newly developed construction process, we had the privilege of
accessing the site to document the process of setting out and earth works.
