INTRODUCTION
A site visit was organized by the program director on the 5th of July 2017. The construction site was
located at Bukit Bandar Raja in Klang, Selangor. A total of approximately 60 students, accompanied by two
lecturers namely Sr. Ang Fuey Lin and Ms. Habizah Binti Sheikh were attended to the site visit.
The purpose of the site visit is to allow students to understand and visualize the theories taught in
lectures. The site visit will provide us with a hand on review and a clear understanding on construction.
The construction project for this site is a 16-story ‘Rumah Selangorku’ apartment tower, two blocks
with 285 units each, accompanied by a 5-story car park with 851 spaces. Companies cooperating in this
project are SIME DARBY USJ DEVELOPMENT SDN. BHD. (developer), SIME DARBY PROPERTY (KLANG) SDN.
BHD. (owner), KAMALISMAIL ASSOCIATES (KLANG) SDN. BHD. (architect), ACE ALLIED CONSULTING
ENGINEER SDN. BHD. (mechanical and electrical engineers), PERUNDING REKACEKAP SDN. BHD. (civil and
structural engineer), YUSOFF ASSOCIATES (quantity surveyor) and NADI CERGAS SDN. BHD. (contractor).
Two days before the site visit, we attended the CIDB Green Card Course and were given a lecture
about the safety precautions that we should be aware of when we enter a construction site. The site
consisted of variety possible death threats or potential threats where accidents may occur.
On the day of site visit, students were informed to gather at the destination at 9.00am sharp by
carpool. Attendance was taken upon arrival and we were greeted with open arms by the contractor and
other officers who were in charge of our site visit. Students were divided into two groups to tour around
the site. Before going in to the site, we were given a brief on the construction project and inspected to
ensure that we were all properly attired with safety helmet, long pants and covered shoes. Safety is after
all the most important aspect in a construction site.

TECHNICAL OBSERVATION
PILE CAP & COLUMN STUMP
A pile cap is a thick concrete mat that rests on concrete or timber
piles that have been driven into soft or unstable ground to provide a
suitable stable foundation. It usually forms part of the foundation of
a building, typically a multi-story building, structure of support base
for heavy equipment. The cast concrete pile cap distributes the load
of the building into the piles.
After the pile cap is done, column stump is constructed on top of
the pile cap to support ground beam and column above. The
function of the column stump is to transfer the load of a building
onto the pile cap, and also raising ground beam and ground floor
slab to the required height above ground level.

Site Survey & Site Clearance
Prior to starting the site clearance, the contractor will carry out a thorough survey of buildings, structures,
fences, trees, etc. that are to be removed. Next, the engineer will be fully informed of the results of the
survey and the amount and extent of the demolition and site clearance will then be agreed with the
engineer.
Before commencing any excavation or fill, the area must be cleared of all trees, stumps, roots, bushes,
vegetation, debris, materials or other obstructions. Site clearance removes objects which are not designed
or permitted to remain.
Excavation
Excavation of soil is necessary in construction point of view and it should be done by hand tools or
machineries based on the area of the land or depth of excavation. By the process of excavation, the land is
cleaned from tree roots, strums, organic impurities etc., which should cause harm to the foundation.
Excavating of pit is carried out to the desired depth to build pile cap and column stump. Excavation can be
done at ease by using tools which are operated by mechanical force.

larger depths of excavations.
Fig.4 Trees and hedge that arefound within the boundary of the site must be cleared.

Formwork to Pile Cap
Before the installation of formwork to pile cap, concrete of the head of the piles will be cut off to 75mm
above the reduced level. Any cracked or defective concrete will be cut away to provide a full and sound
section to be cut-off level.
Once they are done, formwork is built and installed for the foundation. Timber is used as a material
for the formwork. Formwork serves as a temporary mould into which fresh concrete and reinforcement
are placed to form a particular reinforced concrete material.

Reinforcement to Pile Cap
After the installation of formwork, reinforcement cage is laid on lean concrete. Spacer blocks are attached
to the outside of the reinforcement cage to prevent the reinforcement from touching the formwork. This
ensures a layer of concrete surrounding the outside of the reinforcement cage. Its function is to protect
the reinforcement from the corroding effects of exposure to air and water.
Reinforcement to Column Stump
Column stump reinforcement is installed and tied to the bottom of the pile cap reinforcement cage.
Reinforcement bars to column stump are bent manually and held together using binding wires. Binding
wires play a significant role in holding the reinforcement bars during construction.

Filling of Concrete
After all the reinforcement bars have been laid, approved ready-mix concrete will be transported from
batching plant to the site by mixer truck. From mixer truck, concrete will be delivered to casting location by
concrete bucket. Concrete is then discharged into the formwork. Vibrating of the concrete prevents the
formation of honeycomb. Several days are needed for it to set and harden.
Formwork to Column Stump
Timber formwork is installed on top of the set and harden concrete of pile cap. Formwork making
guaranteeing the necessary strength but also considering aspects of economical use of material and easy
formwork stripping. Improperly made formwork, which gives way or breaks when the concrete is placed,
results in heavy material damage or, in the worst case, may cause serious injury of persons.

Filling of Concrete
Crane is used to lift the concrete bucket and transport it to the casting location. Concrete is then poured
into the formwork to form the column stump.
Removal of Formwork
Once the concrete for column stump is set and harden, it’s then time to remove the formwork for both the
column stump and pile cap. The construction workers will dismantle the formwork by removing the nails.
Backfilling
Backfilling is the process of putting soil back inside a trench or in a foundation when the excavation has
been completed. The backfill process requires skills and knowledge on the specifications, contract
requirements and understanding soil conditions. Every soil has unique characteristics requiring different
construction techniques to ensure optimum performance. Once the pile cap and column stump are
finished constructed, backfilling of soil is done to fill in voids in underground.

Materials Involved in Constructing Pile Cap and Column Stump
Formwork
Formwork is the board sheeting which erected to contain and
mould the wet concrete during placing and initial hardening
period. Formwork also acts as a temporary structure that
support the freshly placed concrete. There are two types of
formwork, namely permanent and temporary structures. In
this construction of pile cap and column stump, temporary
formwork is used. Temporary formwork supports the concrete
until it reaches adequate strength. This type of formwork can
be erected in a short time, highly loaded for a few hours
during the concrete placement and it can be disassembled for
future use.
Reinforcement
Reinforcement is done to the pile cap and column stump to make it stronger. In most cases, reinforcement
bars are placed after the forms are finished. Reinforcement usually comes in 12m bars and bent manually
into desired form. There are two types of reinforcement, namely high tensile and mild steel.
Reinforcement bars are usually high tensile which are stronger than mild steel.
Concrete Spacer
Concrete spacer is a piece of concrete that place in between
reinforcement and the soil. The function of concrete spacer is
to prevent the direct contact of reinforcement and the soil. In
this construction, spacer used are made of concrete. Normally
the height of concrete spacer is either 25mm or 50mm.
Concrete
Concrete is a mixture of cement, fine aggregate, coarse aggregate and water at a certain
proportions to control the quality and strength of the resultant concrete. Concrete mixes can be
denoted by 3 or 2 numbers, such as 1:2:4 which refers to 1 part of cement, 2 parts of fine aggregate,
and 4 parts of coarse aggregate. Concrete Grade 30 is used for the reinforced foundation as it is a
very strong concrete mix. The compositions are mixed in concrete mixer truck and transferred to
the concrete bucket. It is then lifted by the crane and transported to the casting location.

CONCLUSION
I could say that this is my first time ever to enter into a site as a lawful visitor. From being exposed
to the knowledge of CIDB Green Card, I got to know that it is crucial to own the card as a site visitor. This is
because a site consisted of variety possible death threats or potential threats where accidents may occur.
This site visit is truly an eye opener as I had the chance to observe the equipment, machineries, and
materials used in a construction. It amazed me how these individual components could end up
constructing a multi-story building. Besides that, I earned the knowledge of the construction process of pile
cap, column stump and other structures. I also managed to explain and describe them clearly.
Through this site visit, I got to be familiarized with the working environment of a Quantity Surveyor.
This visit benefits me in a lot of aspects and prepared me to overcome with unexpected problems in the
future.
Finally, I was grateful that Ms. Ang organized this site visit for us. Although the visit was not as long
as I expected, I still had the chance to grasp the knowledge needed.
