4. The site - Ramal Villa is located in Kajang. It
is an extremely low density project with only
71 units. Apart from having a single
detached unit, the freehold and guarded
community has two other types of semi-
detached units, which are the Courtyard
and the Generations. The building style
emphasizes on modern design by having
flat slab roofs and simple facades. To
enhance greenery, rooftop gardens are also
available for each and every single unit. The
site is well circulated as it is easily
accessible from major highways where the
site are just thrown stone distance to LDP
and Sungai Besi Highway.

Heath and hygiene on site are one of the prime points that needs to be taken very seriously as it ensures the health of the work labour which are
essential to ensure the smooth construction process and productivity.
SANITATION
A typical toilet on site
Sanitary convenience should be taken into consideration as to ease the
workers and also to ensure the cleanliness and hygiene of the surrounding of
the construction site.
Rows of self constructed concrete
toilets on site
• Sanitary facilities and conveniences should be segregated according to
gender of users for the construction workers.
• Water are also provided for in order to maintain the cleanliness and hygiene of
the sanitary facilities on site.
• Ventilation and sufficient lightings are also needed to be present in these
facilities in order to ease convenience in these facilities.
TEMPORARYCANTEEN
Canteens are also important and essential in any construction site as it
provides food and beverages in order to maintain workforce and
productivity among construction workers and hence indirectly
maintaining efficiency and productivity within the construction site and
project.
• Condition of the temporary canteen needs to be well hygiene as it
affects the cleanliness of food and beverages being consumed by the
construction workers.
• The temporary canteen needs to also be well lit, well ventilated and
shaded as to provide comfort for the construction workers when they
are having their meals.
• To ensure cleanliness, the canteen needs to be located further away
from construction dumpster and waste and also sanitary facilities.
• The location of the temporary canteen needs to also be strategic
around the site as to ease the convenience of the construction
workers to have their meal after work.

12. GARBAGECOLLECTION
Garbage collection facilities are one of the most important facilities to be present around the construction as to ensure the cleanliness and the
hygiene of the surrounding of the construction site. The garbage facilities serve to act as a dedicated space for the disposal of sanitary
wastes, construction wastes and also domestic wastes around the site such as food and beverages wastes after consumption.
Main dumping site around the
construction site without any
sort of proper dumpster
Food and beverage wastes
are being littered around the
construction site disregarding
the site cleanliness.
Temporary facilities are not well
taken care off and gradually
becomes dumping spot for
certain construction waste
Construction wastes such as
spoilt and unusable zinc sheets
are dumped randomly around
the site.
The construction site has many
random dumping spots which
cleanliness are not emphasized.
Site safety | 10
13. Bad practices are common in local construction sites due to the lack of surveillances from higher authorities and also lack of emphasis on the penalties on
certain wrongdoings.Most of the bad practices are concerning site safety and also the health and cleanliness on construction site.
BAD PRACTICES AROUND CONSTRUCTIONSITE
HEALTH & HYGIENESITE SAFETY
Construction workers are not well
equipped with safety glove while
handling and bending the
reinforcement bars. This practice is
dangerous to the workers as it will
injure the hands of the workers
while working.
Scaffoldings are not well equipped
with construction safety nettings.
This will increase the tendency of
the construction to fall from height
and also materials from falling
below.
Main dumping site is not
properly managed and
increase the chances of pests
breeding.
The canteen is situated at a
close distance from the main
dumping area which is
unhealthy and unhygienic for
the workers in terms of food
consumption.
The sanitary facilities are
not provided with efficient
water supply for cleaning
and it is not well lit and
ventilated. This is
unhygienic as it will attract
pests such as flies and in
the long run producing
unpleasant stench.

21. External works are mainly the preliminary preparation that has to be carried out in order for the actual construction works to be done smoothly. This is to
ensure the smooth process of the construction works and to provide the construction and completion of site clearance and earthwork around the designated
site boundary. External work types consist of site clearing, site levelling and excavation, designating temporary facilities and also utility connections.
SITECLEARINGWORKS
Site clearing works are mandatory and serve as the fundamental basis in preparing the site for construction. It is the process of clearing any site construction
obstruction which could be any sort of existing natural vegetation or structures by which the presence are inappropriate for the commencements of site
construction. Site clearance works mostly include the removal of vegetation such as natural trees and stumps that are within the site boundary.
Two cuts for the undercut forming a pie shaped
cut line in the base of the tree trunk facing the
direction of which the tree is intended to fall. An
backcut which is 3-5cm above the base of the
undercut is cut at right angles to the falling
direction.
In order to remove the remaining tree stump the
dozer blade is placed against the stump and a
lifting action is furthered applied onto the stump.
The tractor is backed and the dozer
blade is lowered.
The stump is tilted forward until the
roots in front of the dozer blade are
slightly lifted out fromthe ground.
The dozer blade is now inserted
under the lifted roots.
While lifting the blade, a pushing
force is applied in order to break the
stump out of the ground and hence
entirely removing the tree from the
ground.
If the tree trunk still resists falling, a wedge is
hammered into the backcut to the direction
intended for the tree to fall.

22. EARTHWORK&EXCAVATION
After the procedure of site clearance works are done, earthworks are to be proceeded. Earthworks are engineering works involving the excavation and
land filling process through the constant moving, excavating, replacing, refilling and backfills bulk materials such as earth and soil on site. Besides,
excavation works are also to prepare the construction site for even and well levelled land for the smooth process of construction works to take place.
The topography and the elevation of the
terrain are studied and surveyed thoroughly.
The contour lines signifies the changes of
land in elevational views.
The cut line is then made to estimate the
amount of land to be cut and to be
backfilled with the amount of cut land.
The cut line is the marked to the intended
level onto the existing slopping land and
whereby holes are filled under the cut liens.
The marked cut lines will be removed and
to be used as filler to achieve the accurate
and efficient desired landscape..
The slopping topography to be cut or
excavated and the remaining bulk material
are used to backfill the designated the
spaced needed to be filled.
After ground has been cut out from its
original ground level, a battered surface will
form and the original ground level is
reduced to form a flat surface.
The designate zone that needs to be filled
are then filled up to the intended level, thus
producing a higher formation level as
compared to the original ground level,
hence forming a flat surface as well.

24. SITESETTINGOUT
Site setting out is also considered as one of the major, essential and important preliminary works that needs to be carried out in order to allow the
commencement of construction works. Setting out is basically the establishment of the marks and lines to define the site boundary, the definite position
and also the level of the construction elements for the construction works to be proceeded with efficient and accurate reference to them.
• The temporary bench mark or the site datum post (1) is being set up as the
main reference point of the rest of the set up points.
• The base line is then being set up with reference to the datum post and on
the other hand acting as the reference line itself to all other setting out lines
and points by which all can be related.
• Corners posts are then set up in order to mark the main building boundary.

30. SLUMPTEST
Slump test are also one of the major point that should not to be taken for granted as it is once of the most significant task and procedure of
external works. Slump tests serves to examine the mixture and quality of a batch of premixed concrete and hence to determine its suitability of
usage for construction works .

Externalworks | 28
31. SLUMPTESTPROCEDURE
The slump cone is dampen and is
filled with 1/3 full by volume and rod
25 times with a tamping rod.
The cone is further filled with 2/3 by
volume. This layer is rod 25 times
penetrating through by not all the
way through the bottom layer. The
rodding action is distributed evenly
over the entire cross section of the
layer.
The cone is later then filled till it
overflows. This layer is again rod 25
times with rod penetrating into but not
directly through the second layer. The
rodding is again distributed evenly
across this entire cross section of the
layer.
The excess concrete from the top of
the cone is then removed using the
tamping rod as a screed. The
overflow base of the cone is also
cleaned.
The cone is then lifted vertically
immediately with slow, even motion.
The cone must be ensured to not be
tilted in anyways throughout this
process. The withdrawn cone is
then inverted and place next to the
slumped concrete without touching
it.
A straight edge is laid across the top of the cone.
The amount of slump in inches is then measured
from the bottom of the straight edge to the top of
the slumped concrete at a point over the original
center of the base. The examination should be
completed at an elapsed time of mot more than 2
½ minutes. The concrete is then discarded and
shall not be used to perform any other tests.

Shallow piled foundation is used for the particular site. Piling is a more suitable foundation for this structure rather than the rafting foundation because the
structure is a three storey semi detach house with a soil condition that is not hard and also very stable. Also, it is able to withstand the load capacity of the
semi-detached house. Raft foundations are more potentially used for unstable type of soil or soils that are highly compressible .
Foundation of a structure is always constructed below the ground level so as to increase the lateral stability of the structure. It includes
the portion of the structure below the ground level and is built, so as to provide a firm and level surface for transmitting the load of the
structure on a large area of the soil lying underneath. The solid ground on which the foundation rests is called the Foundation Bed.

38. GRADE BEAM
BEAMS
A beam is a horizontal structural element that is capable of withstanding transverse loads (floor slab/roof slab) primarily by resisting bending. They transfer
all the loads including its self weight to other structural elements below (columns/walls). In other words, a column is a compression member.
The grade beam used at the site was of reinforced concrete, and it was positioned horizontally at ground level to support the superstructure, transferring
the load to the piles below.
Pile caps are interconnected with grade beams
and ground slab to ensure lateral forces can be
distributed to all the piles.
The piles and grade beams of the building at our site work in conjunction to elevate the
structure, provide vertical and lateral support for the elevated home, and transfer loads
imposed on the elevated home and foundation to the ground below.
Beams&columns | 36
39. GRADE BEAM
Construction Process
Reinforcement andFormwork
Footings and grade beams must be reinforced to resist the
moment forces that develop at the base of the piers due to the
lateral loads on the foundation and the elevated home
After the piers have been drilled and poured, trenches are dug for the grade beams. Wood is used to create
formwork and steel reinforcing is placed inside the formwork. The reinforcing from the pier is tied to the
reinforcing in the grade beam.
Grade beams must be a minimum of 200mmby 600mm with 2 – 15M bars top and bottom.
An acceptable void form must be
placed under all grade beams.

COLUMNS
A column is a vertical structural elementthat transmits, through compression,the weightof the structure above (the ceiling/roofslab) to
other structural elements below (foundation).In other words, a column is a compression member.
Reinforced concrete columns
Sizes of the columns
The sizes of the
concrete columns on
site differ from one
floor to another. The
bottom most floor has
a more thorough
reinforcement, and is
larger in size due to
the amount of load
and weight that it will
have to withstand.
For design purposes, the columns are separated into
two categories: short columns and slender columns.
These columns are prone to face different kinds of
failures.

Formwork
Concrete formwork is the temporary structure builtto support and confine concrete until it hardens.Formwork refers to vertical forms used to form walls and column.
It consists of the following:
Side & End Planks, Yoke, Nut
& Bolts. The two end & two
side planks are joined by the
yokes and bolts.
Adjustable
steel clamps

45. Columns
Reinforcements
Concrete is strong when compressed, but they need to be somewhat elastic to
regain their height after being compressed by live loads (people), and if they’re
turned to twisted by dynamic loads (wind/earthquake). Concrete columns must
always have steel reinforcement because they are subject to bending.
The columns on site are composed of concrete with an embedded steel frame to
provide reinforcement.

Bracing
Column bracing maintains the accuracy of the column form
position and plumb so that it is within tolerance. It is able to
withstand results of forces acting on either the column formwork
or the bracing.
On site: Bracing is applied to support the formwork of columns

48. When constructing the floor system it is important to take the type of flooring, the laying of
pipes and reinforcement into consideration. The type of flooring in a house must be
adequately supported by the flooring structure below. Floor systems are the horizontal surface
of a room or interior space and its supporting construction. Floor systems must support both
live loads and dead loads which then transfer to the supporting beams, columns or
loadbearing walls.
Concrete slab are common foundation or floor systems in many parts of the world. Particular
in warmer climates with soils that are stable. Concrete slabs are plate structures that are
reinforced to span either one or both directions of a structural bay.
A building concrete slab consists of (from ground up) 4” of sand, gravel, or crushed stone; a
layer of 6 mil polyethylene used as a vapor barrier . A layer of wire mesh embedded in the
concrete.
One way slab is supported on two opposite side only thus structural action is only at one direction. Total load is carried in the direction perpendicular to
the supporting beam. If a slab is supported on all the four sides but the ratio of longer span 1 to shorten span is greater than 2, then the slab will be
considered as one way slab. Main reinforcement is provided in only one direction for one way slabs. One way slabs are designed for flexure and shear
on a per meter width basis, assuming that they act as a series of independent strips. Thus one-way shear in slabs is often referred to as beam shear,
and design for flexure and shear is carried out using a beam analogy.
Ground floor slab is built on a compacted hard ground
supported by beams.

One way slab supported on beams on all four sides
One way slab supported on beams on two sides
• Provides useful flat surface
• One way slab may be used when there is architectural
limitations
• It is the simplest form of slab design
• Main reinforcement placing is one way, so there is a little
congestion than two way slab.
When a slab is supported only on two parallel apposite
edges, it spans only in the direction perpendicular to two
supporting edges. Such a slab is called one way slab. Also,
if the slab is supported on all four edges and the ratio of
longer span(ly) to shorter span (lx) i.e ly/lx > 2, practically
the slab spans across the shorter span. Such a slabs are
also designed as one way slabs. In this case, the main
reinforcement is provided along the spanning direction to
resist one way bending.

50. The slab above ground floor is known as intermediate slab. It usually takes 7-14 days for concrete slab to cure. But for intermediate
reinforced concrete slab it requires formwork for temporary support while
the concrete is wet, which delays the construction process for
approximately 7 days. The intermediate floor includes an intermediate floor
layer including an elastic and resilient material. Intermediate floor slab is
usually cast between 100-300mm, depending on the live and dead loads
asserted on the slab.
Slab formwork and shoring
Fresh concrete must be shaped and supported by formwork until
it cures and able to support itself. Moreover, temporary supports
called shoring are used to support beam and slab forms.
INTERMEDIATE SLAB
slab | 48
51. Step3
Concrete class is cast on top of the wire reinforcement
with the formwork acting as a mould. The concrete is
then spread by until the form is full and even. The ground
taxes 1-2 days to cure and after curing of 14 days, the
formwork are then removed.
Step1
The desired area for ground of a site is excavated and
compacted, the hole is usually larger than the slab for
formwork to fit in the hole.
Step4
Scaffolding and shoring are placed on the ground floor to
support the timber centering of the first floor. The
formwork of the first floor is installed on the timber
centering.
Step5
Concrete is then casted into the formwork that holds the
welded wire reinforcement in place. Finally, a layer of
concrete is casted on top of the reinforcement and an
intermediate slab is formed.
Step2
Formwork is installed around the compacted hardcore.
Welded wire reinforcement is layered on top of the damp
proof membrane.

52. SLABDETAILS
• Formwork for slabs and beams consists of sole plates,
wedges, props, head tree, planks, batten and ledgers.
• Beam formwork rests on head tree.
• Slab form work rests on battens and joints
• If prop height are more than 8’ provide horizontal braces.
A beam-and-slab system, with a one way slab, and beams cast
compositely with the slab, is a highly efficient floor system.
Ground floor depth usually varies from 100-300mm, depending on
the ground bearing capacity and also the live ad dead load.

54. TYPESOFWALL
A wall in general, is rows of bricks stacked vertically to a certain height. Walls are important element in a building as it not only bears the load of
the home; it also serves as a divider between spaces. They are also sound barriers and fire walls that protect the interior space of a building.
Bears 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.
Does not support any gravity loads from the building hence doesn’t
bear any weight besides its own.
1. Roof spans between external walls and internal load bearing wall.
2. Floor spans fromexternal wall to internal load bearing wall.
3. Load bearing wall transmits part of roof load to foundation.
4. Load bearing wall transmits part of roof and floor load to
foundation.
5. Roof spans fromexternal wall to external wall..
6. Floor spans from external wall to external wall.
7. Non load bearing walls built off floor surfaces.
8. External load bearing walls transmit part of roof and floor load to
foundation.

Tap it into place until the top edge of the brick lines up exactly with the fishing
line guide..
Step6
Scrape away any excess mortar that has been squeezed from between the
bricks as you go before it dries and hardens. Ensure that you remove the
mortar before it hardens.
Step8
Once the corners are built,simply move the fishing lineup, row by row, and fill
in the spaces between the corners. Because your bottom row is level and
your corners are vertical, your whole wall is sure to be level and vertical.
On-site:
Fishing lines are
extended at
corners to indicate
levels. During brick
layering process.
Step7
Use a spirit level to check that the row is level and to ensure that the corners
are vertical (i.e. straight up and not leaning in or out).
BRICK-LAYERING PROCESS
Step1
Bricks must be laid on a concrete slab or foundation.
Step3
Place enough mortar to lay 2-3 bricks at a time.
step4
'Butter' each new brick by applying mortar onto the end of the brick
before placing it hard up against the preceding brick and into the
mortar bed. .
Step2
Start by building the corners. To lay the first course of bricks, use
your trowel to spread mortar onto the concrete surface. Use a
fishing linestretched tight between the corners to lay the first row
of bricks. The back top edge of every brick laid must be exactly
in linewith the fishing line.

On-site:
Party walls (fire wall) are builtusing burnt clay brick due to
its fire resistant property. The rest of the walls are built
using cement sand bricks because it is more economical.
On-site:
Bricks at the top of the non bearing walls are arranged
diagonally to fill up the space at the top of the wall.This is
a bad exercise in construction as it weakens the wall
greatly.
On-site:
Walls are chased after builtto run electrical wires and
power points.This is done before plastering process.
walls | 54
57. PLASTERINGPROCESS
Step1
When plastering walls, try to avoid working in the direct sun or drying
winds. Plaster needs to retain its moisture for as long as possible.
Step2
Load your hawk with plaster mix and scoop it onto the steel trowel.
Apply to the wall with pressure.
Step5
Wet the leveled plaster with water (flicked lightly with a brush), then
use a float to smooth the surface.
On-site:
Metal brackets are installed to ensure straight edges when walls are
being plastered. Thickness of plasters are also marked to ensure
even plastering work.
Step3
Plaster small areas at a time. A whole wall should be completed in one
operation.
Step4
Once the plaster starts to stiffen, level the surface by pulling a straight
edge over the plaster with a sawing motion.
Step6
Cover the plaster area with plastic or use a fine spray of water to keep
it damp for as long as possible (up to 7 days).

59. Stairs are the conventional means of vertical access between floors and different levels in buildings. Stairs are a series of steps, each elevated a
measured distance, leading from one level of a structure to another. It should be constructed to provide ready, easy, comfortable and safe access up
and down with steps that are easy to climb, within a compact area, so as not to take up excessive floor space.
TYPEOFSTAIRS
2 parallel flights of straight stairs joined by a landing
that requires 180 degree turn in the walk line.
Half-turn staircases are also a variety of staircases
with straight flights. Just like quarter-turn stairs they
also have a landing, but here it changes a direction of
the flight by 180 degrees already and also serves as a
place for rest when moving. The landing divides the
staircase into two, thereby reducing quantity of treads
in one flight, and makes walking more comfortable.
Staircases of this type are very convenient, functional,
and safe.
COMBINATIONOF
OPENANDCLOSE STAIRWAY
The staircase is sandwiched between
a wall and a open stairwell.
The double quarter turn or double quarter landing
allows the stair case to turn through 180 degrees. This
is achieved by turning 90 degrees on two large square
steps or landings.

Formwork is the molding into which wet concrete is poured to give the user greater control over the exact shape of the finished, cured concrete.
Formwork can be built with almost anything but is most often built with a combination of timber, plywood, and steel or aluminum hardware.
Formwork can either be dismantled after the concrete has cured to an acceptable level, or it can be left to remain embedded on a permanent basis.
The basic concept of formwork is the creation of “walls” that will sand-which concrete poured between them.

63. CONCRETESTAIRCONSTRUCTION
Concrete stairs span between landings. Where there are loadbearing walls around the stair, it is generally economic to build. The landings into the
side walls as one-way spanning slabs and construct the flights as inclined slabs between the landings. Concrete staircases are especially popular
as it lasts longer relative to wooden staircases and is cheaper than installing staircases constructed from metallic materials. When designed
correctly, a concrete staircase is not only functional but can also add aesthetic value to the overall design of the building.

72. Roof is an assemblage to provide cover for homes, buildings, and commercial, industrial, and recreational areas. Roofs are constructed in different forms and
shapes with various materials. A properly designed and constructed roof protects the structure beneath it from exterior weather conditions, provides structural
support for superimposed loads, provides diaphragm strength to maintain the shape of the structure below, suppresses fire spread, and meets desired aesthetic
criteria.Modern roof construction usually consists of an outer roofing assembly that is attached atop a deck or sheathing surface, which in turn is supported by a
primary framework such as a series of beams, trusses, or arches.

THEPURLINROOF
The purlin roof consists of both rafters and purlins. The ridge purlin is supported by posts. The rafters act as simple supported beams between
the purlins, either with or without cantilever. Purlins must be supported by load bearing walls or by structural beams and any horizontal thrust
from the purlin must be catered for. the strut and its associated connections and supports should be of adequate size and strength to resist
buckling and to carry the appropriate loading.

foundation by channelling water away from its base. The gutter also
helps to reduce erosion, prevents leaks in basements and crawlspaces,
protects painted or stained surfaces by reducing exposure to water and
provides a means to collect rainwater for later use.

75. CORRUGATED METAL ROOFING (SITE)
Metal roof decking is corrugated to increase its stiffness. It is designed for pitched, flat, or arched construction on virtually all
types of buildings. Roof deck is popular because it is strong, lightweight, economical, and easy to install. Therefore, the smaller
columns are used to support the structure in residential houses.
CORRUGATED METAL DECK
Advantages:
• Lightweight and reduce the load
• Reflects solar heat and can cut back
on cooling costs immensely
• High durability
• Low maintenance
Disadvantages:
• Noisy in the event of heavy rain
• Higher cost
Fastener arrangement
Reason using screw
as fastener:
• Faster to install
• Consistent screw installation
streamlines the inspection
process with no special
inspections
• Save time and money with
painted decks
• No need to repaint or touch up
from welding
• Reduce costs by eliminating
the need for welding leads,

TILESROOF(REFERENCE)
Roof tiles can be an alternative for the metal roof of the selected site. It is also designed to drain away the rainwater as the overlapping of the tiles
prevent rainwater fromdripping into it. Materials such as clay, fibre cement and concrete are used for the roof tiles.
Where the tiles meet the gutter is called the eaves. An eaves course of tiles is normally shorter than the rest of the tiles used and is normally
invisible when the roof is complete as it is fully covered by the layer of tiles above. It is there to provide a second layer of tiles for waterproofing.

The concrete roof tiles are nailed to roof
battens running parallel to the roof eaves.
Gaps are left in the battens so that water
passing through the tiles drains down to the
eaves, and a waterproof membrane is below
the battens.
Hurricane clips are recommended or often
required by local building codes in hurricane
prone areas.
The clips are fastened to the roof deck,
usually with multiple fasteners, and clip to
edges of the roof tiles. In high wind and
hurricane areas the number of fasteners is
also increased.

79. Upon completing this Building Construction project over the span of two months, we were given multiple opportunities to expand our knowledge
on building construction. We had the chance to visit a construction site, as well as learned the construction process of erecting a building. We
were brought around by the site manager, and were explained little details of the construction site as well as experiences that he has gone
through. Due to the site being an ongoing construction site, we followed the safety specifications that were given, we brought our own safety
helmets and wore safe covered shoes and long pants to ensure our own safety. We got to witness different processes of constructions, such as
wall plastering, roofing, construction of stairs, wood framing of doors and constructions of all other sorts.
Upon doing researches we also came to realize that from the site that we visited, certain inappropriate practices were implemented, and some
construction methods not properly applied. We have learned to be more aware the consequences, and grasped that these applications should
never be administered solely for the function of cutting costs or time. Construction is a lengthy but fairly complicated process, and little details
should not be easily overlooked.
In conclusion, we were grateful that this project brought us an opportunity to be involved with the construction industry. Throughout this project
we took a glimpse of what it takes to build buildings of all sorts that can be seen today, from little details to a larger scale. We also came to realize
that regulations that were set must be followed, and communication is really important amongst professionals of the building industry. Architects,
engineers and contractors required to be able to communicate and coordinate among one another to produce excellent results. Thus, being able
to visit the construction site gained us a generous amount of knowledge and experience that we believe that we would later apply further in the
future.
