S I T E & S A F E T Y
The construction industry has long been considered as a difficult, dangerous and dirty occupation due to the high number of accidents,
injuries and deaths. Construction workers are exposed to different rinks. Example: falling from heights, movement of the plant and
machinery, electrical shocks, drowning, excessive noise and etc.
SIGNAGES
The reason of placing safety sign is to deliver
the important of the information to public and
warn the public about hazard that could be
happen in construction site. No only that, the
sign provides information of who is working
and the contact as well.

SCAFFOLDING
Scaffolding is a temporary structures that used to support
people and hold materials that are to be used for
construction or repair of buildings and other structures.
They aid safety of the workmen and allow access to areas
that are difficult to reach. They are constructed by using
metal tubes with metal platforms or with bamboos and
wooden planks.

Excavator is the machine that can excavate the soil of
various types forcefully and then using hydraulic
system a hydraulic force is generated and utilizing
this force bucket is pull back towards the machine.
Bucket of excavator is replaceable. If front bucket is
exchange with some other attachments then
excavator can be used for multi-purpose. For
example: pile diver, hydraulic jack hammer etc…
CRAWLER
EXCAVATOR
-Two endless tracks.
-used in hilly areas where
risks of sliding of machinery
are on the verge.
-Low ground pressure
because of spreading of load
on large area and also used
where soil support is weak.
THE ARM
-Consists of a bucket and a boom.
-Can be replaced by hammer or
breaker.
-Does the digging work.
THE CAB
-The driver’s seat consists
of the control systems and
steering

MOBILE CRANES
A mobile crane is a cable-controlled crane mounted
on crawlers or rubber-tired carriers or a hydraulic-
powered crane with a telescoping boom mounted on
truck-type carriers or as self-propelled models.They
are designed to easily transport to a site and use with
different types of load and cargo with little or no
setup or assembly.
WORK BASED ON SIMPLE
CONCEPT
-Transmission of forces from
point to point through a fluid. -
Two pistons fit into glass
cylinders filled with oil and
connected to another.If
downward forces apply to one
piston, then the force is
transmitted to the second
piston through the oil in the
pile.
THE BOOM
-It is the most recognizable part of the crane. Does
heavy lifting of materials such as beam and
column.
THE JIB
-This lattice like structure
frees up the boom to extend
fully and provide maximum lift
range.
THE COUNTERWEIGHTS
-Keep cranes from
becoming unbalanced
while hoisting heavy
loads.
10

BACKHOE-LOADER
The backhoe loader is an engineering and excavation
vehicle that consists of a tractor, front shovel and bucket
and a small backhoe in the rear end. Due to the small size
and versatility, backhoe loaders are common with small
construction projects and excavation type work.
LOADER
A loader is a heavy equipment machine used in construction to move
aside or load materials such as asphalt, demolition debris, dirt, feed,
gravel, logs, raw minerals, recycled material, rock, sand, etc. into or
onto another type of machinery.
THE BOOM
-Bent upwards to make
it easier to dig.
THE BACKHOE
-Use to dig up hard compact
material or lift heavy loads.
THE TRACTOR
-Move easily over all
kind of rough terrain by
controlling the steering
in the cab.
THE LOAD
-Use to pick up and push
large amount of loose
materials into holes.
THE CAB
-Driver’s seat consists of the
control systems and steering.
THE BUCKET
-Use to load materials.
-Can be replace by other devices and tools.
-Different size of buckets.

CONCRETE MIXER TRUCK
The concrete mixer is a device that homogeneously
combines cement, aggregate such as sand or gravel,
and water to form concrete. A typical concrete mixer
uses a revolving drum to mix the components. For
smaller volume works portable concrete mixers are
often used so that the concrete can be made at the
construction site, giving the workers ample time to use
the concrete before it hardens.

- Site layout and Security and safety
- Setting out and levelling
SITE CLEARING
- A construction site is usually prepared in two steps : clearing the vegetation and also cut and fill the surface soil. It can be done by hand
or by machineries depending on the scale of the site.
- Based on the scale of the sites selected, the machineries needed for clearing the site includes : Multipurpose excavator, bulldozer,
dumper, since they can not be done manually.

SOIL FILLING
After all the vegetations are removed from site, it will be followed by the process of soil filling, which basically cuts and fill the topmost
surface of the soil, to produce an even surface for the site. The fill dirt used is usually the subsoil and underlying soil parent material which
has little soil organic matter or biological activity. They are taken from a location where soil is being removed as a part of leveling an area for
construction, while it may also contain sand, rocks, and stones, as well as earth.
The other site was built on slope (2 floor
basement and 3 floor above ground floor). Soil
investigation plays a much more important
part in this site, as it helps to reduce the risk of
erosion and land massing. More work is done
to prevent accidents from happening, such as
the construction of retention walls and deeper
piling for foundation.

PIles used on the site are
reinforced concrete columns, which are
precast and driven (hammered) into the
ground down to a level of firm and stable
bearing ground for supporting the load.
Situations which lead to the necessitate use of piles are:-
- Insufficient load bearing capacity is offered by the soil at a shallow depth, but sufficient is
available at a greater depth
- The nature of the soil at a shallow depth is variables and performance is unpredictable in
site.
- Soil at shallow depths are subject to shrinkage or swelling.
- Building are subjected to an uplifting force, and require to be anchored to the ground.
By the way in which they are
installed
By the way in which they transfer
the load to the ground
Pre-cast RC pile is set in the ground by
forcing or driving a solid pile to the

Pile Caps plan in site
Pile cap reinforcement
- The main reinforcement is two-directional formed in loops over the pile heads to spread the loads.
- To provide structural continuity, the reinforcement in the piles is bonded into the pile cap; this may necessitate
the breaking out of concrete from the heads of piles to expose the reinforcement.
- The heads of piles penetrate the bottom of pile cap some 100 to 150mm to ensure continuity of the members.

REINFORCED POURED CONCRETE BASEMENT CONSTRUCTION
Basement is the portion of a building which provides accommodation and is below ground level. There are few types of basement
construction which is precast concrete basement construction, concrete block basement construction as well as reinforced poured
concrete basement construction. Reinforced poured concrete basement construction is used in the site.
Reinforced poured concrete basement construction is a multiple steps operation.
This type of basement construction is much more stronger and resistant to water
infiltration than other two types. However, waterproofing is still needed for the
basement walls and the added water-tightness of poured concrete will give you a
second line of defense against damaging water intrusion.

A retaining wall is a structure that holds or retains soil behind it. Retaining walls are used in the construction of basement below ground
level, wing walls of bridge and to retain slopes in hilly terrain roads.
-Uses reinforcement bar to give more strength
to the retaining wall structure and improving
its ability to hold the soils behind it.
-Resists the lateral pressure by structural
action such as bending.
-Texture and appearance affected by the use
of formworks, composition of concrete mix
and surface treatment after casting.
-Provides greater speed of construction and
control of quality.

5.2 RETAINING WALL
GRAVITY RETAINING WALL
-The thickness of wall increases with height.
-Resists the lateral earth forces by its weight and any soil resting on it, hence, is rather massive in size.
-Typically shorter in height.
-Usually are sufficiently enormous to be unreinforced.
-Monolithic cast walls are generally formed on site.
-Usually built in stone masonry, and occasionally in plain concrete.
-Plain concrete gravity walls are not used for heights exceeding about 3m, for economic reasons.

SUPERSTRUCTURE
is the part of any structure that is built above its foundation or basement.
It serves the purpose of the structure’s main intended use.
Concrete was used for both sites’ superstructure casting as it is able to withstand
great compressive forces from 20-40 MPa while reinforcement bars would
complement the concrete by giving the structure greater tensile strength.
COLUMNS
are vertical structural elements which transfer load from the roof, beams, slabs,
ceilings, and its own weight to the foundation.

COLUMN INSTALLATION
Reinforcement bars are set up
by lapping onto the bars below
them (in this case, for the
ground floor, would be the bars
of the column stumps).
Formwork inserted where columns
should be.
Yorks: clamping devices to maintain the
column form and prevent the formwork
from spreading under fluid pressure of
the concrete casting.
Concrete is casted into the
formwork. Formwork is
shaken to eliminate any air
bubbles and even out the
concrete layer.
Concrete goes through a hydration
reaction to increase its strength
up to 2.5 times. Formwork is
removed after 3 days and rough
edges are smoothened out.

A roof is part of a building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from
animals and weather, notably rain but also heat, wind and sunlight. The word also denotes the framing or structure which supports that
covering. A roof may also provide additional living space, for example a roof garden.
MONOPITCH ROOF FEATURES
The monopitch roof is always made out of one single
roofing surface. This kind of roofing is true to its
name; Mono meaning single and the slope is referred
to as the pitch. Monopitch roof construction is
generally stand alone roofs which imply that you don’t
need to attach them to any part of your roof. They
differ considerable from traditional roofs which
usually tend to have various pitches and slopes on
various parts of the roof.
- Sloping roof may be categorized into
Low-slope roofs up to 3:12 and
Medium-to high slope roofs 4:12 to 12:
12
- The roof slope affects the choice of
roofing material, the requirement for
underlayment and eave flashing. And
design wind loads.
- The height and area of a sloping roof
increase with its horizontal
dimensions. Sloping roof planes may
be combined to form a variety of roof
forms.
Sloping roof may have structure of
1. Wood or steel rafters and sheathing
2. Timber or steel beams,purlins and
decking
3. Timber or steel trusses.
62

- Nailing strips can provide if roofing
is laid over a non-nailable roof deck.
- Standing seams are made by folding
up the adjoining edges, then folding
their upper portion in the same
direction
- Batten seams are made by turning
up the adjoining edges against a
batten and locking them in place
with a metal strip.

A flat roof is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and
flat roofs have up to an approximate 10° pitched angle. Flat roofs are an ancient form mostly used in arid climates and allow the roof space
to be used as a living space or a living roof.
- An upturned edge beam can

Being able to visit multiple construction sites and witnessing all the thoughtful planning, precise measurements, and
hard labour that goes into the building construction in person has been a great privilege to us all. We were able to
receive a much greater perspective and appreciation toward all the fine details that go into constructing a building
from seeing the building process right in front of our very eyes that no amount of words in a textbook can give us and
we would strongly urge any aspiring architects out there to take the initiative to seek out ongoing construction sites
for their own enlightenment.
Besides being able to better understanding the various topics from our module Building Construction I, visiting these
sites expanded upon our knowledge from our previous semester’s Building Materials as we got to actually the
practical uses of all the different materials we studied on up close that can’t be seen in the final design such as brick
and concrete in some cases.
When designing any structure, many factors must be taken into consideration. Of course its design will be of
majority’s main concern especially if the majority are the public, but how practical the structure is along with the
planning and process of how it starts from nothing and rises from the ground to stand on its own are just as
important if not more.
