1.0 IntroductionIn this assignment, we were required to produce a report on the construction site visit for combination of 3 subjects which are Building Materials, Construction Technology 1 and Measurement 1.

The title of this site visit is “ Cadangan membina dan menyiapkan 96 unit rumah berkembar (40’ x 60’) serta infrastruktur yang berkaitan di Sekyen 2A, Antara Gapi, Hulu Selangor, Selangor.”

On 19 November 2015, about 88 students attended the site visit. We were to be divided into two buses. We were required to wear safety helmet, long pants and sport shoe/safety shoe while visit the construction site.

When we started our site visit, we were given a brief talk about the safety and rules at the site. Then we kicked off our site visit. Our site visited was leaded by a site contractor. He explained information of the building briefly and clearly.

Below is the construction site plan that I have obtained from the site. From this plan, we can clearly see that there are three types of houses that are being built and that are Type 1, Type 2A, Type 2B and Type 3.

2.0 ObjectiveThe main objective of this site surveying is to give exposure to students where they will be able to describe, explain and understand the method and process of construction in accordance to the sequence of work on site, especially the Pad Footing.

The other objectives of the site visit are:

To let us experience the actual working environment and learn more about the life of being a Quantity Surveyor on site.

To allow us to have a better understanding of the types of the building materials involved in the construction site.

To aware the important of taking care of personal safety and the safety precautions that may lead to accident.

To enable us to understand the building structure and the sequence of constructing a building.

To gain more construction technology knowledge that new to us. To make it easier for us to get clearer image of how the structures look like in real life. To make us understand the important of teamwork and communication skills while

working together with the construction team such as engineers, project managers, contractors and workers.

To observe the usage of the construction equipment on site such as crane and bar bending machine.

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 explain the construction of buildings and the scientific principles that underpin the

design and construction.

3.0 Content / Technical ObservationsWhen we reached the construction site, I saw a project information board that was placed outside the fence. The function of the project information board is to state the role of each constructor involved. Moreover, there are a few temporary works installed at the site which are accommodation for workers, material storage, security and scaffolding.

Around the surrounding area of the structural buildings, there exists a few scaffolding with safety net cast around it to protect people from falling down by limiting the distance they fail. It is used to support people and hold materials that are to be used for construction or repair of buildings and other structures. It aided the safety of the workmen and allowed easy access to areas that are difficult to reach. They are constructed by using metal tubes with metal platforms. Besides that around the inner part of the scaffolding, they have cleverly installed a series of stairs for the purpose of easy movement of workers up and down the building structure.

4.0 FoundationThe foundation used in this construction is the pad foundation. The construction site had chosen the pad foundation due to the structure of the building constructed which were double storey house. Pad foundations are used to support individual or multiple columns, spreading the load to the ground below. They are generally square or rectangular in plan, with the plan area being determined by the permissible bearing pressure of the soil. The shape in plan will be dictated by the arrangement of the columns and the load to be transferred into the soil.

Footing is the lower part of the foundation which is constructed below the ground level in solid surface. The purpose of footing is to transfer the live and dead loads of the structure to the soil over a large enough area so that neither the soil nor the building will move and it resist settlement and lateral load.

No matter what type of footing and foundation is used, a certain sequence should be followed. The sequence can change slightly according to the method involved. The basic sequence is as follows:

1. Find the amount of site preparation needed2. Lay out footing and foundation shape3. Excavate to proper depth4. Level the footing corners5. Build the foundation forms6. Reinforce the forms as needed7. Estimate concrete needs8. Pour the concrete footing9. Build the foundation forms10. Reinforce the forms as needed11. Pour the concrete into forms12. Finish the concrete and embed anchors13. Remove the forms14. Waterproof and drain as required

4.1 Pad FootingPad footing is the support used at a point load such as columns or framed structures. They may be circular, square or rectangular and consist of a block or slab of the thickness. The pad footing may be stepped if they are required to spread the load from a heavy column. The pads are usually shallow but deeps one can be found depending on the structure.

Before the installation of pad footing, there are factors that need to be observed:

Accessibility Condition of ground Nature of the load requiring support Proximity to other structures Water table

Advantages of P ad Footing

Economic due to control of foundation size Shallow form of foundation needs little excavation Shape can be designed to accommodate tight sites

Disadvantages of P ad Footing

Can become very large to cope if used for high point loads Limited foundation to dealing with point loads of framed building Weak against uplift forces, wind forces and earthquake forces

Cost of P ad Footing

Additional cost for timbering, high cost compared to Trench and Strip Footing

Process in Making P ad Footing

1. Clearing the site2. Excavate : small excavation because pad foundation requires small size of space3. Formwork for Pad filling4. Install reinforcement : up to ground floor, extra reinforcement called starter bar5. Pour concrete into the formwork : column stump6. Let concrete cured then Earth backfill7. Place formwork and install reinforcement for ground beam8. Pour concrete then backfill slab base and soil compaction

5.0 Method of Construction of Pad Footing1. Clearing the site then pegging the site with correct position of foundation.

2. Excavation commences from the reduce level, down to the desired level (soffit of footing with allowance for thickness of lean concrete).

3. Lay a layer of lean concrete to prepare a clean and firm base for the footing.

8

4. Build the formwork to the side of pad footing and supported by other wood to prevent the formwork collapse when the concrete is being pour into it.

5. Spacer blocks are placed before reinforcements been laid. This is to provide sufficient concrete cover for rebars.

6. Rebars were bent and tied before the whole thing been lowered and placed inside the formwork. Make sure the steel is place properly on spacer blocks, avoid touching the lean concrete below.

9

7. Stump reinforcements are then erected. Length of rebars should be extended beyond stump level and act as starter bars for column above.

8. Provide addition ties to formwork, if necessary.

9. Concrete will set and curing shall be performed to avoid excessive lost of water during hardening. When the concrete has gained sufficient strength, formwork can be dismantled.

6.0 Conclusion / Learning OutcomeAfter the meaningful construction site visit done by us on 19 November, there are countless of valuable information of knowledge gained by me after the visit. Besides, I had the opportunity to learn something that I couldn’t learn from the lectures and textbook. I have better understanding about how a construction site works now after the visit.

I had seen and explored various materials and tools used during the construction period. This is an eye opener for me as I have never had the chance to see it with my own eyes. Besides, I was taught by the site contractor about the various professional construction technique used and its application.

Most importantly, I had the chance to witness how much they emphasize on safeties in the construction site. They demand every worker to have their proper safety equipment on when a construction is going on. Even we, the visitors have to wear safety helmet just like other worker to guarantee our safety during our visit since there might be bricks or rocks that might fall from high ground and might hit our head. Moreover, safety signboard were seen everywhere to always remind their worker to emphasize on their own safety.

Moreover, I can see that cooperation between workers is very important through this visit. Every worker at the construction site is cooperating with each other in order to accomplish the task given. This shows that cooperation is very vital in doing something important.

Besides, construction site manager also plays a very important role. As I can see during the visit, the construction site was well planned. There was a site to throw all the domestic waste, and all the materials or tools were kept safe and sound to ensure their stability and secureness when it is being used in the future. Through this site visit, I was able to know further more about the method of construction of pad footing.

This site visit really helps us to visual better in method of construction of pad footing. The site visit was very interesting and insightful.

In conclusion, this visit has greatly enhanced my knowledge about construction site. I am very grateful to have a chance to visit there as I have gained a lot of knowledge. I wish that I could have more chances like this in the future as in really benefit me a lot.
