INTRODUCTION
In this project, students are required to do a report on a technical
site visit to a construction site. Students need to observe and explore the
site technically in order to complete this project by meeting all the
requirements. There are 3 subjects are involved in this project, which is
Building Materials, Measurement I and Construction Technology I.
Different task is given from each subject to all students. ForMeasurement
I, students need to make technical observations on a site and write report
with photos and description. For Building Materials, students required to
identify the grade of reinforced concrete used in construction site for
column, slab, beam and foundation and explain the advantages and also
disadvantages of these concrete grade used. For Construction Technology
I, students have to identify and explain the type of foundation used in site
with advantages and disadvantages.

INTRODUCTION TO SITE
On 26th June 2015, a construction site visit to The Andes
Construction Site is organized by Ms Ang Fuey Lin to all BQS Sem 1
students. Attendance is compulsory. The site is near to Taylor’s
University with around 15 minutes car distance.
Location of the construction site
The construction site is strategically located at the borderline of
Puchong and Bukit Jalil which is very convenient for transportation,
especially KIDEX Skyway that gives road users a lot of advantages.
Before the site visit get started, lecturer had collected students’
name, I.C and student ID to mark our attendance easily. She had
separated all students into 2 groups and gave us some brief on safety
precautions such as wearing helmet and properattire. The first group is
left from campus at 7:30am sharp and the second group is left at 8:30am.
Bus fee per student is RM15.

For this site project, The Andes is comprising two towers of
condominium and villa.

Measurement I: Technical Observation
Upon arrival, students were all checked to have wearing proper
attire and helmet to ensure our safety during site visit. Project manager,
Mr James Siow is briefly introduced about the site by providing us a
process reportof the construction site.

After briefing, students were formed into groups with 8 people and
led by a site worker per group for further exploration and understanding of
the site. Along the way, the supervisor keep reminding us to be careful of
the ground to ensure our safety. Since the construction is only partially
completed, we only managed to view slab, column, wall, pilecap and also
excavation.
The supervisor led us down to the basement construction by using
a temporary stairs that only fixed into the soil which is very unstable.

stop lawful visitors from stepping
forward.

The first thing I saw after walked down safely from stairs is
reinforcement bars that used in basement slab. The supervisor told us that
mesh fabric would only be used started from first floor.

There are many columns spotted on the basement slab. Some of it
had formwork and reinforcement bars installed while some are done with
reinforced concrete poured and formwork had also been removed. Each
column is less than 4m2 which means that it weighed 8.5 tonne. (1m2 =
2.2 tonne)

concrete to be poured.

A so called “penimbang” is

site that used to lift heavy

Scaffolding are spotted in the
site too.

sides above the slab with

After exploring for every single part of basement construction, the
supervisor then brought us to the next two areas which is doing piling
works and also excavation. There is no beam found in the site because it
had been covered underground.

Building Materials:
Grades of Concrete Used for Slab, Beam, Foundation
and Column
Grade 35
Reinforced concrete Grade 35 is used for slab, beam and foundation.
Advantages:
- It is cheaper than Grade 40.
- It is commonly used in construction industry.
- It has better resistance to fire.
- It has Long service life with low maintenance cost.
Disadvantages:
- It has low compressive strength compared to Grade 40.
- It can cracks easily under service load as the grade of reinforced
concrete is low.
- Its ability to resist sulphate attack is lower than Grade 40.
Slab Foundation

16. 16
Grade 45
Reinforced concrete Grade 45 is used for columns at basement.
Advantages:
- It can maintain the size of column uniform throughout the
building height.
- Ability to earthquake resistance is greater than Grade 35.
- It has higher strength to resist more loads.
- Higher modulus of elasticity, which increases stability and
reduces deflections.
Disadvantages:
- More expensive than Grade 35.
- It is lack of adequate research under field conditions.
- High-performance standards must meet consistently.
- Careful and high quality materials selection is necessary.
Column

17. 17
Construction Technology I: Type of Foundation Used
Pile foundation
Advantages:
- Length can be readily varied to suit varying ground conditions.
- It can be installed in very large diameters.
- End enlargement up to two or three diameters are possible in
clays.
- Material of piles is not dependent on handling or driving
conditions.
- It can be installed in very long lengths.
Disadvantages:
- Concrete is not placed under ideal conditions and cannot be
subsequently inspected.
- Water under artesian pressure may pipe up pile shaft washing
out cement.
- It cannot be readily extended above ground level especially in
river and marine structures.
- Boring methods may loosen sandy or gravely soils requiring
base grouting to achieve economic base resistance.

CONCLUSION
I have learned a lot of things which cannot be found in the books or
notes in this site visit. This is my first time to enter a site as a lawful
visitor and see how a site looks like clearly. A lot of equipment and
complicated techniques used for the construction such as tower crane,
scaffolding, excavator, bull dozer and etc. Now I knew how hard it is to
build a building under scorching sun and dusty environment. This site
visit is a really great time for students to learn and understand
construction which is very helpful in our future. I hope that Ms Ang could
organize such activity again for us to visit site again.
