Page 3: Assignment 1 - Antara Gapi, Hulu Selangor, Selangor

In this individual assignment, we are required to produce a site report after a site visit to a

construction site. This assignment involves three modules, which are Measurement 1,

Construction Technology and Building Materials. The site visit is attended by all Semester 1

August Intake students and two lecturer, which are Miss Ang and Miss Azrina. Before the site

visit, our lecturer has brief us on what we need to wear during the site visit. We are also required

to bring a safety helmet to ensure our safety at the site. During the site visit, we need to note

down what we had saw and learnt at the site.

Objective

Page 4: Assignment 1 - Antara Gapi, Hulu Selangor, Selangor

To learn about site organization and the importance of site safety.

To understand the basics of the construction process.

To witness the usage of construction equipment on site including mechanical plants.

To explore and identify various types of building materials and technology on site.

To able to explain the construction of buildings and the scientific principles that

underpins the design and construction.

To make us understand the significance of teamwork and communication skills while

working together with the construction team members on site.

Introduction of the Site

Page 5: Assignment 1 - Antara Gapi, Hulu Selangor, Selangor

A site visit to a construction site was held in the morning on 19th November 2015

(Thursday). The site is located at Sekyen 2A, Antara Gapi, Bandar Sungai Chik, Hulu Selangor,

Selangor. The site visit was guided by the project manager, Mr Mohd Sobri Bin Hj. Ab. Majid.

The project is about constructing 96 unit semi-detached houses (40’ x 60’). There are

total four types of houses. Type 1 is a flat house; Type 2A is a split down house; Type 2B is a

split up house while Type 3 is a spilt down house. There are total 38 units of Type 2A house, 12

units of Type 2B house, 36 units of Type 2B house and 10 units of Type 3 house.

This project will take about 3 years to complete. It was started at 8th July 2014 and is

expected to complete on 4th July 2016. This project cost around RM 44 million.

Technical Observations Made On Site

We arrive at the site at 9.30am in the morning. On the way into the site, there is an

information board placed in at the entrance. From the information board, we can know some

information about this project such as the contractor, architect and engineers of this project.

There is also a safety sign at the entrance of the construction site. The safety sign provides

information about safety that we need to pay attention when we are in the construction site such

as what we should do and what we should not do in the construction site.

Besides, the construction site is surrounded by vertical hoarding to define the limit of the

site and to prevent unauthorized persons access to site. When we arrived at the site, we were

gathered at the entrance and the project manager, Mr Mohd Sobri Bin Hj. Ab. Majid briefed us

about the safety precautions. After the brief, we began our visit guided by the project manager.

First, I have seen some machineries park at the construction site. We are quite familiar

with the machineries because we have learned before in class. Some of the machineries are truck,

mobile crane, front shovel, etc.

Besides, I also saw a lot of different material placed on the floor along the site. For

example, reinforcement bars, BRC, bricks and metal roof truss. Moreover, there are also houses

that have finished construct.

Moreover, the scaffolding used in the site is independent scaffoldings. Independent

scaffoldings do not rely upon building for support. Pile cap is also found at the site. Pile

foundation is also one of the foundations used to build the house. It is depends on the soil

condition of the site.

Furthermore, I saw pad footing at the site. The size of the pad footing is in different size

because the size of the pad footing is depends on the load above it. I also saw a worker taking off

the formwork of the pad footing.

Next to the pad footing is the column. There are some columns have already done, but

some of the formwork of the column have not taken it off yet. I also saw beam and formwork to

beam.

After that, we stop at the site office. The site office is located inside a big cabin. Before

we leave, there was a worker teeing the stirrups with a wire.

We finish our site visit around 11.30am and we went back to our campus. We arrive at

campus around 1.00pm.

Pad Footing

How a pad footing is constructed?

Step 1 : The size of the pad footing is set up according to the plan dimension.

Step 2 : Excavate the earth to the require depth.

Step 3 : Plywood formwork is built at the perimeter of the pad footing.

13

Page 15: Assignment 1 - Antara Gapi, Hulu Selangor, Selangor

Step 4 : 50mm thick of lean concrete Grade 30 mixture is then poured inside the formwork to prepare a clean and firm base for the footing.

Step 5 : Reinforcement bar is bent and tied and placed inside the formwork.

Step 6 : Stump reinforcements are then erected. Length of reinforcement bars should be extended beyond stump level and act as a starter bars for column above.

Step 7 : Concrete Grade 30 is poured into the formwork.

Step 8: After the concrete is set and cured, the formwork can be dismantled.

What are the materials involved in constructing a pad footing?

1. Reinforced Concrete Grade 30

Reinforced concrete is concrete in which wire mesh or steel bars are embedded to increase

its tensile strength. Concrete has great compressive strength, but very little tensile strength.

To overcome this weakness, concrete is cast around steel reinforcing bars. These bars have

high tensile strength. As the concrete harden, it grips the steel to form a bond. Concrete

Grade 30 concrete has a 1 : 2 : 3 Ratio (Cement : Sand : Aggregates). The grade means the

concrete compression resistance at 28 days.

2. Lean Concrete Grade 30

Lean concrete is a mix where the amount of cement is lower than the amount of liquid

present in the strata. The main function of the lean concrete is to provide the uniform surface

to the foundation concrete and to prevent the direct contact of foundation concrete from the

soil.

3. High Tensile Reinforcement Bar

The high tensile reinforcement bar used is T12 and T16 in the pad footing. T12 is high

tensile reinforcement bar with 12 mm diameter, while T16 is high tensile reinforcement bar

with 16 mmm diameter.

4. Plywood formwork

Plywood is an artificially manufactured wooden material used for making concrete

formwork. It is strong, durable and light weight. The availability of different thickness

plywood in the market makes it popular for different sizes concreting work. It is possible to

have smooth finish in which case on cost in surface finishing is there.

Conclusion

This is the first time I visit a construction site. I have gain a lot of new knowledge

through this site visit. In this site visit, I have chance to look at all the material we have learnt in

class such as reinforcement bars, metal roof truss, BRC, etc. Besides, I also saw different

machineries wat the site such as truck, back hoe, concrete mixer, etc.

Moreover, I get to know how a house is built from the foundation up to the roof. We also

have a chance to ask question about the material and the process of the construction.

Furthermore, I leant that the safety is really important in the construction site. We should always

be alert and be careful all the time. We should always wear safety helmet in the site.

Finally, I want to say thank you to the project manager, Mr Mohd Sobri Bin Hj. Ab.

Majid the land surveyor, Mr. Mohd Hafizi Bin Mohammad. They answer all of our question and

willing to tell us more about it. I really gain a lot of valuable knowledge and I hope to have

another chance to have a site visit at another construction site.
