Introduction

First of all, in this assignment, we were required to produce a report on the construction site visit for combination of 3 subjects which are Measurement 1, Construction Technology 1 and Building Materials. The site visit located at The Andes Construction Site (Address: Jalan Mas 1, Bukit Jalil, 58200 Kuala Lumpur). The Andes is the name of freehold development. Located in the borderline between Puchong and Bukit Jalil. It is expected to be completed construct in 2018. This property is under the helm of Villamas, and it is made of two residential unit types, condominium and villa terrace.

The Andes has a good population location because it is surrounded by various features such as shopping malls (Giant, Tesco, IOI Mall), schools and institutions (Taylor’s Lakeside Campus, Sunway University, Monash University), and medical facilities (Sunway Medical Center).

Objective To understand the basic of construction process, demonstrate a

systematic and orderly mind.

To broaden our horizons with information of the newest construction technology used in construction industry.

To help us on knowledge for the preparation for being a quantity surveyor.

To observe the usage and function of the construction equipment commonly used on construction site.

To make us aware of the importance of safety and understanding of safety problem and site condition.

Technical Observation

We arrived at the construction site in the morning around 9.00 a.m. On the way to the construction area, we observed what was around the site. According to the information board below, we can know the contractor of the building is Villamas and several detailed information of the building. According to the project manager of the site, they are currently which cost roughly, RM2.5 million.

Firstly, the project manager gave a little briefing about the construction site safety and also explanations about the site remind us to put the safety at firs the first place. Then, he showed us the documents of the construction sure as progress sheet, plan, and also some drawings. He told us that the construction site is divided into three phases, the first phase of the site, which was located upon entrance of the site, had its work below lowest ground floor level completed and the contractors was working on the construction of the basement carpark of the condominium.

The information board placed in front of the site and the site surrounded by vertical hoardings.

After the briefing, we separated into 7 to 9 students a group with a guide to walk us through the site and also explain the structure, progress, material, equipment in the site.

During the site visit, I observed that the contractors was working on structural element, which is also known as substructure; such as foundations, columns, and beams. The reinforcement bars that used for columns is Y12, Y16 and Y32, for the concrete part, used of reinforced in-situ concrete Grade 40.

construction site, I observed that the workers were working on the foundation of the building. The foundation used in the construction site is Piled Foundation. It is suitable for weak and unstable soil, multi stories buildings.

I do observed that, there were lesser workers working on the second phase of the construction site compare to the basement carpark. There are several construction equipment and mechanical plants. Such as excavator and water suction pump in the second phase of the construction site.

Piled Foundation

Structure of Piled Foundation.

The Andes Piling Plan.

Advantages DisadvantagesVery strong foundation. Not suitable for low rise

buildings.

Able to support superstructure. Very expensive for construction & material.

Pile Cap are very effective to distribute load among piles & provide rigidity to column support.

It waste useful excavated space & resulting heavy back filling to get a floor. (increase in costing)

Piles can be made in advanced and used on site.

Driven pile are not suitable in soils of poor drainage qualities.

Lastly, currently the progress of the third phase is removing water from the water table by using water suction pump while waiting for the piled foundation after cleared he huge amount of water. I also do notice that most of the reinforcement bar in the construction site are Y12, Y16, Y20, and Y32.

Last but not least, at the ending part of the site visiting the guide showed us the piling plan of the construction for The Andes and also explained to us that they have constructed the biggest pile cap with huge of concrete which is 24BP1200A.

Advantages DisadvantagesReinforced concrete has a high compressive strength compared to other building materials.

The tensile strength of reinforced concrete is about one-tenth of its compressive strength.

Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress.

The cost of the forms used for casting RC is relatively higher.

Can be easily moulded to any shape required, it is widely used in precast structural components. It yields rigid members with minimum apparent deflection.

The main steps of using reinforced concrete are mixing, casting, and curing. All of this affect the final strength.

Fire and weather resistance of reinforced concrete is fair.

Shrinkage causes crack development and strength loss.

This is my first time for site visit. I feel very excited while the first step going in to the construction site. In this site visit I have gained a lot of new and interesting technology knowledge and experiences. I have also learnt the importance of team work and leadership between the workers for constructing a building.

Through the site visit, I was able to understand and have a clearer vision of what I have learnt in class. Such as the steps to constructing a building, types of foundation use in site, materials and equipment’s, roles involving in a construction, types of reinforcement bar and concrete, structural of a building.

Lastly, I would like to thanks my lecturers Ms Ang, Ms Azrina, and Ms Aishah were guiding me throughout the whole semester in Measurement 1, construction Technology 1 and Building Materials. What we have learnt now, is for the future in our working in construction industry apply what we have learnt in to working in the future.
