SITE CLEARANCE
0322991
Site clearance is the first step in preparation of construction site where it involves clearing vegetation and removal of soil to
reduce levels in the proposed site. This is to ensure that the proposed buildings will be free from vegetation and the soil is
suitable for foundation to improve the stability of proposed buildings.

SUBSOIL DRAINAGE
0322991
Subsoil drainage is installed within the ground to remove excessive water from the soil to avoid the passage of ground moisture
to the interior of the building and damage to the fabric of the building. With the help of subsoil drainage, it helps to improve the
stability of the ground, lowering the humidity of the site and also improving its horticultural properties.
The system is
terminated at a
suitable outfall which
is river or stream.
Precautions should
be taken to ensure
the system will not

15. 4.0FOUNDATION
Foundation is the lower portion of the building usually located below ground level, which transmits the loads of the
super structure to the supporting soil.
PURPOSE OF FOUNDATION:
• To hold together and increase the stability of the structure.
• To distribute the load of the structure over a large bearing area.
• To load the bearing surface at a uniform rate to prevent unequal settlement.
• To prevent the lateral movement of the supporting material.
• To secure a level and firm bed for building operations.
Foundations are generally divided into deep foundation and shallow foundation.
DEEP FOUNDATION: used to transfer the load of a structure down through the upper weak layer of
topsoil to the stronger layer of subsoil below. There are different types of deep footings including
impact driven piles, drilled shafts and caissons.

CLASSIFICATION OF PILES
• Used when the soil is soft and no hard
strata available to a certain depth.
• Carrying capacity is derived mainly from
the adhesion or friction of the soil in
contact with the shaft of the pile.
• Transfer their load to the ground through
skin friction.

PROCEDURE OF PILE FOUNDATION
0319735
Step 2: Pile Cap Step 3: Footing Step 4: Ground Beam
A pile is a column of concrete
that extends downward deep into
the soil. It is a type of deep
foundation.
A pile cap is defined as a
concrete block cast on the head
of a group of piles. Pile cap
transfers the load from the
structures to a pile group and the
load further transfers to firm soil.
A base that supports the
structure. Footing is the wider
part of concrete that goes under
concrete wall and is used to
keep the wall from sagging.
Ground beams are designed to
support brickwork or to form a
permanent shutter to the edge of
in-situ concrete floor slab. The
beams can be designed to
withstand any heave forces with
the use of void forming or
compressible materials.
PROCESS OF PILE FOUNDATION (DETAILS)
1. DRIVE
Starter or drive pile until maximum
at pile point.
2. WELD
The plate join of adjacent pile
for extension.
3. APPLY
Bitumen at joint as water proofing
coating to prevent rust.
4. DRIVE
The extension pile into the ground
until maximum.
5. CUT
Cut off the excessive extension
pile using a pile cutting machine.
6. EXCAVATE
Surrounding soil of the pile
cluster by approximately
300mm depth.
7. CAST
The pile cap in situ.
8. LOAD TEST
Carried out by putting loads on
the pile for certain period. It is a
pass If the pile does not crack.
18. 4.0FOUNDATION
• Concrete block cast on the head of a group of
piles.
• Ground stability increases with depth & pressure.
• The top of pile is more vulnerable to movement &
stress.
• Tie the pile heads together.

Simply supported slab
These are slabs which rest in a bearing and for design purposes are
not considered to be fixed to the support and are therefore, in theory
, free to lift.In practice however they are restrained from
unacceptable lifting by their own self weight plus any loadings.
Concrete slabs
Concrete is a material which is strong in compression and weak in
tension and if member is overloaded its tensile resistance may be
exceeded leading to structure failure.
SLAB
Types of slab
One way slab
Length is two more times the width. Slab
supported on two sides and bending takes
place predominantly in one direction
Two way slab
Length is less than double the width
(approximately square). Slab is
supported on all four sides and
bending take place in two
directions.
Suspended slab
Suspended slabs are slabs that are not in direct
contact with the ground. They form roofs or
floors above ground level

4.Vapour Barrier
Incorporate a damp-proof membrane
(DPM) under the concrete slab.
5. Reinforcing
Install the welded steel
reinforcement mesh and rebar. (two
layers of BRC A8).
6. Mixing Concrete
Distributes the aggregate evenly
throughout the cement paste,
ensures that all of the cement has
been fully saturated in water, and
removes large air voids.
2. Soil Support System
A thin layer of graded, granular,
compactible material is normally used as
fine grading material to minimize friction
between the base material and the slab.

8.Consolidation
Once the concrete is in place, it should be consolidated
to remove large air voids developed during placement
and to make sure that the concrete has flowed into all of
the corners and nooks of the formwork. This process is
also called compacting.
9.Finishing
Final treatment of the concrete surface after it has
been consolidated to achieve the desired properties.
This can be as simple as pushing a wide blade over
the fresh concrete surface to make it flat screeding.
10.Curing
As the concrete hardens and gains strength it becomes
less and less vulnerable, so the critical time period is
the first hours and days after it is placed.
7. Placing Concrete
Placed concrete into the formwork that
defines its final position and shape.
22. REINFORCEMENT OF CONCRETE SLAB
Steel Reinforcing Bars and Welded Wire Reinforcement
Concrete is very strong when it is squeezed in compression but very weak when it is
being pulled apart in tension. Steel reinforcing bars and welded wire reinforcement
are very strong in tension, have similar thermal expansion and contraction properties
to those of the concrete, and thus can handle high-tension stresses while the concrete
can take substantial compressive stresses.

Diagonal cracking & crushing of
concrete can be prevented in joints.
Mostly, for this large column size is
the most effective.
• Concrete fromwork purpose is to place and form concrete
mixture according to prescribed size and design.
• It is a temporary building structure which needs to be

25. ColumnBeam
Beam is horizontal load bearing member
which is used to withstand load. It does
so by allowing the structure to maintain
its shape and not bend. It is commonly
reinforced with rebar.
Column is vertical load bearing member
which transfer loads from beams to the
foundation. Reinforcement are applied to
strengthen their compressive force.
Column Beam
Beam and column are elements that make up a building’s structure.
For our particular site, the beams and column are made of concrete. There are two different type of concrete beams
and columns, pre cast and in-situ. Pre cast being beams and columns that are pre-casted off site and brought on site to
be assembled on to the structure and in-situ being casted on site using formwork which was that was used in our site.
Our site uses cast on site reinforced concrete. Concrete is strong in compression but weak in tensile forces. Therefore
steel reinforcement bar(rebar) are applied. Into concrete beam, slab and column to increase their tensile strength and
resist compression, tension, shear and bending.

Lateral Reinforcement
• Number of reinforcement bar used in
columns may be varied instead of varying
the size of columns.
• Formations of lateral reinforcement bars
depends on the number of vertical
reinforcement bars used in a column.
• Lateral ties should have a minimum
diameter of 10 meter.
• Type of reinforcement used is usually T12,
reinforcement steel with diameter of
12mm.
• Concrete columns mat be supported by
isolated footings or by pile caps.
• Length of overlapping reinforcement
bar is 24 times of the diameter of bar.
• Dowels tie column to support beam or
slab.
• Vertical reinforcement should not be less
than 1% nor more than 8% of the cross
sectinal concrete beam.
• Types of reinforcement steel includes T12,
T14, T16, T20, T25, T32 and T40.
• ‘T’ represents reinforcement steel and the

LOAD BEARING WALL
A load-bearing wall or bearing wall is a wall that bears a load resting upon it by conducting its weight to a foundation structure. The
materials most often used to construct load-bearing walls in large buildings are concrete, block, or brick.

PLASTERING
Plastering is to coat a layer of plaster on the wall . The purposes of plastering are
to give resistance to the wall, increase fire resistance of the building elements,
and to give a good appearance to the wall. Cement plaster is usually coated on
masonry wall.
Skim coating is a name for a plastering technique. The widely used mixture is
made up of lime putty and sugar sand. Skimming is a thin coat of plastering layer
applied to the existing plaster to upgrade the surface. The thickness of skimming
depends on client’s request.

STAIRCASE
0322732
A staircase is a construction designed to link a large vertical distance by
dividing it into smaller vertical distance which is called steps.It allows
easy movement between different levels.
Aspect that should be considered when designing a staircase is the
placement of stairs, ease of travel and most importantly the safety.The
design of a staircase should take proper consideration of the width,
treads, riser, nosing, landings, handrails which are the requirement of
a staircase.
TYPES OF STAIRCASE USED ON SITE
1.U shaped stairs with winder treads
"Winder" stairs refer to stairways that make a turn
without including an intermediate landing or platform
to provide a flat rectangular turning space.
2.Double Quarter Landing Stairs
Represent a variety of straight stairs, which also include a
landing. But here the landing is needed to change a
direction of the flight by 90 degrees and at the same time it
serves as a place for rest when moving.

Reinforced Concrete Staircase
Concrete staircase are usually
specified for its durability, long
lasting, high strength, fire and
weather resistance.
Reinforced concrete stairs are
designed as slabs and requires
structural analysis of load,
support and span conditions.

36. Starter bars in staircase
In order to achieve a connection with the subjacent floor there must
be properly placed starter bars. Moreover, starter bars must be
positioned and at the superjacent floor for the staircase of the next
level.
1.Placement of starter bar
Before the positioning of the staircase’s formwork
(planking), the starter bars are properly bent at the
necessary height.
During the final phase of the positioning of the
staircase’s reinforcement, the lower rebars (in red
color) are tied to the distribution bars to their
proper position. The stringers and the risers are
placed last
2.Staircase formwork and reinforcement at the starter bars
3.Starter bars at the top of staircase
the lower rebars of the staircase are not continued into
the staircase slab and therefore, they are not
presented.
4. Staircase construction in following phase
The staircase will be supported on those starter
bars and the starter bars of the lower floor.

CONSTRUCTION PROCESS OF REINFORCED CONCRETE STAIRCASE
Step 1: Measuring
Calculate the height of one floor to the other
(total rise). Measure the horizontal distance of
the staircase (total run). Measure the width of
each step from left to right in the area where the
staircase will go (staircase width).
Step 3: Building and Assembling Formwork
The form can be made by plywood or framing
lumber. The first step is to cut the side forms
according to the tread and riser calculations.
They must be securely adhered to the
building's foundation. Depending on the width
of the stairs, you might have to add bracing to
the center of each riser
Step 2: Determine the dimension of foundation
The dimension of foundation will be the length
of total run by the width of the staircase
measured in step 1.

Step 4: Reinforcing
Reinforcing the concrete staircase
with steel.
Step 5: Preparing Concrete
Produce sufficient and well mixed
mortar with portable cement mixer.
Step 6: Pouring Concrete
Start from the bottom and pour one step at a time.
Make sure the mortars are spread evenly. Grease
the inner surface area of your to release the panels
easier after the cement set.
Step 7: Add Finishing
Repeat the trowelling process several
times for each step to smooth the steps.
39. Step 8: Curing
Spray the steps with curing compound and
cover it with burlap. Once the concrete has
hardened for a week, removed the form
lumber.

Step 9: Installing the handrails
i) Position the stair railing onto the staircase
where it will be installed
ii) Mark the position
iii) Drill pilot holes into the staircase at the
marks you made
iv) Place the railing into the pilot holes
v) Pour cement into the hole to fix the
handrail

Identify brickwork
location and door
position
Use planks and nails to prop up metal
door frame. Ensure the correct
direction of the door hinge then erect
the door frame.
Use spirit leveller to
check whether the frame
is properly plumbed.
Begin brickwork by laying
the bring into the rebate
behind the back or the
metal door frame.
Place mortar into each gap between the brick
and frame of each layer. This is to ensure the
frame is properly filled to give rigidity and
strength by becoming an integral part of the
structure.
Wire masonry anchors
are used to ties with the
brick and the metal door
frame. These tie are for
binding the bricks.

SLED ROOF
Also known as the monopitched roof, is a roof structure that has one sloping surface
and the sloped surface does not rest on any form of wall on the opposite ends.
Monopitched roof encourages good drainage during rainy weather as well as aiding in
reflecting heat away from the building if oriented appropriately. It is one of the easiest
roof structures to build and requires less cost.
Our site consist of 2 types of sled roof:
• Metal roof
• Clay tiled roof

CONSTRUCTION PROCESS OF METAL ROOF
1.The rafters are installed following the direction of
the roof slope. Each rafters are 12 to 24 inches
apart. The rafters act as the spine for the roof.
Rafters
2.Then the purlin is installed with a string like tool
called tie rod, which is used to hold the purlin in
position so that the distance between each purlin
will be the same.
Purlin
Tie rod
3. After purlin and rafter, A layer of reflective foil
laminate is put into place. It helps cooling and
prevents condensation. Which can cause roofing
sheets to rust prematurely.
Reflective foil laminate 4. Next will be putting on the metal roofing sheets
The metal roofing sheets are light, and are usually
passed up to the roof by hand, one by one.
They’re laid in place, and are carefully marked and
cut for hips and valleys. Metal sheets is then
drilled and screwed down.

CONSTRUCTION PROCESS OF CLAY TILED ROOF
1. The construction of tiled roof begins
with installation of the guttering and fascia boards.
2. Measurements are made
and set-out nails are
hammered in place along
the rafters to hold the
battens, which are timber
pieces that run horizontally
across the surface of the
roof to keep everything in
place.
3. A layer of sarking (commonly a reflective foil
laminate, or RFL) is then laid down over these set-
out nails, with the reflective side facing
downwards.
4. Next, anti-ponding board (APB) is installed
underneath the sarking at the edges of the roof.
The purpose of the anti-ponding board is to
prevent water from pooling underneath the tiles
at the outer edge of the roof.
5.Tiles are then laid out
across the roof and
clipped on. Tiles at the
edges are cut to make
even lines along the hips
and valleys of the roof.

SUMMARY
In this project, we learn about the construction process which is the part where ideas become reality. The
underappreciated middle part of architecture. We studied the building process through observation, self-
experience and also research. From site & safety, plant and machineries, external works, foundation,
superstructure, doors, windows to roofs. Each part of the process shows utmost importance in producing the final
outcome, the piece of architecture that the people can enjoy.
