3. Introduction
A site visit to Andes construction site was held on 26th of June 2015 by the
programme director, Sr. Ang Fuey Lin. We gathered at Taylor’s University Lakeside
Campus to take bus and get to the site. Our class was separated into 2 groups so that
it is easier for the site visit. My batch is the second batch so our bus left campus at
sharp 9.30a.m. We were told to wear proper attire for this site visit due to safety
precautions. Long pants and covered shoes or site boots are required, and also the
most important is the white helmet. After half an hour, our bus has arrived our site
which located around puchong area.
After we arrived destination, we were briefed by the project manager who is Mr.
James Siow. He briefly talked about the construction project and site to us. We were
separated into few small groups. Then, we had started the tour in the construction
site with the guidance of Mr. James and his colleagues.
From the briefing, we knew that the scope of works included site clearance,
earthwork, construction of bored pile and pile caps work. Besides, they also work for
comstruction for basement slab, beams, retaining wall and ground floor slab
including column lift wall, ramp and staircases starter bars from basement to ground.
This project will cost around rm21,500,000.00. The project last around 24 months
started from 5th of May 2014.

4. Objectives
The objectives of this techinical site visit is to :
1. To understand how the construction process go on.
2. To fully understand the machinery used in construction site with the real
references such as bar bending machine, cutting machine and so on.
3. To gain more knowledge from the site visit by the guidance of the experienceful
professionals when they are giving us information for each station of the tour.
4. To discover the types of construction technologies used in real life.
5. To see and touch the real building material for construction from site that used
to construct a building and able to identify the types of building material used in
the site.
6. To understand the future job’s scope and role in the industry including reading
the drawings and also real site visit for future.
7. To experience the construction site including understanding the safety
precautions in the site such as wearing helmet and boots for personal safety.
8. To know more about the teamwork in construction industry by understanding
the roles of architects, project manager, engineers, contractor and etc in the
construction site. Able to understand how do they work together.

5. Content / Technical Observations
Types of foundation
This construction site has applied pile foundation. A pile foundation consists of 2
components which are pile caps and single or group of piles. Piles has high bearing
capacity to transfers the loads from building structures. Pile foundation is used when
the soil condition of the site is not that good. Piles can be made from concrete, wood
or steel. The selection of type of pile foundation is based on site investigation report
so that it can suggests the type of pile foundation to be used. However, the function
of the pile foundation is to control the settlements, increase the factor of safety for
heavy loads building since it is reliable and more.
This is the diagramof pile cap and photo of pile and pile cap from what we have
seen.
Based on the site visit, pile foundation is used for both block A and block B as well as
its depth is more than 3metres below the finishing level. Besides, based on the
explaination from the person incharged, the type of pile foundation is bored pile
method. Bored pile is used for those tall buildings or massive industrial complexes,
which require foundations that can bear the load of thousands of tons, most
probably in unstable or difficult soil conditions.

6. Advatages and disadvantages for pile foundation
Advantages Disadvantages
Can be designed to withstand high
bending and tensile stresses
Displacement of soil during driving may
lift adjacent piles or damage adjacent
structures
Construction operations not affected by
ground water
May break during driving necessitating
replacement piles.
Almost vibration and noise free Required heavy machinery to process.
Can be driven in ver long lengths Higher cost
Bored pile method is required when there’s heavy buildings with large loads and
when there is a risk of damage to surrounding buildings through vibration.
Advantages of bored pile method
 Can transmit heavy loads
 Almost noise and vibration free
 No need to support bore hole as concrete replaces the void created
Disadvantages of bored pile method
 Large plant needed to excavate earth
 Require reasonably goof soil content to avoid bore hole collapsing.

7. Reinforcred concrete grade
Reinforced concrete grade is an index for the compresive strength of the harden
concrete depends on the quality and quantity of cement, water and aggregates.
Different grades of reinforced concrete would have different workability. From the
site visit, we have asked the person in charged about the reinfored concrete grade.
We knew that different building structures would have different concrete grade.
Concrete grade :
 Foundation – Grade 35
 Column – Grade 45
 Slab , wall and beam – Grade 35

9. Scalfolding in the site to enable
labours can access the structure
easily
The labour was removing the
formwork which the concrete is
readily harden in 24 hours
Labours are installing formwork
with the help of hammer
Concrete cover is done in this
way.
