Introduction A site visit was organized on the 26th of June 2015 by our Measurement 1 lecturer Ms Ang Fuey Lin. Before we were allowed to visit the site, we were given a weeks notice to prepare a safety helmet to ensure our safety for the site visit. During the day of the visit, we are asked to arrive at Taylors University at 9:00 a.m. sharp as the meeting point. The site was roughly 30 minutes away from our University and it is located at Bukit Jalil. When we arrived at the site, we were given a 15 minute briefing from the project manager of the site about the project they are currently handling which costs roughly, RM21.5 million and for this project, they had to construct the biggest pilecap their company has ever made which is 24BP1200A. After a short introduction about the project they were undertaking, we were given another short briefing about the safety precautions we have to take while surveying the site as the condition of the soil for this project was quite muddy, we are to be careful when walking around the site to ensure we do not slip and fall which could lead to a lot of problems. When the briefing was completed, we were finally given the tour on the site.

Type of foundation used for the site

The type of foundation used for the project were pilecaps. The grade of concrete used for the columns are Grade 45,the grade used for the beam is Grade 35, the concrete grade used for the slab is Grade 35 and the concrete grade used for the foundation is Grade 30. The advantages and disadvantages of using pilecap foundation are:AdvantagesDisadvantages

High individual load capacity.Advanced planning is required for handling and driving.

Piles can be precast to the required specifications.Cost increases as the depth of the site cannot be determined in advanced due to cutting extra lengths and adding more lengths.

The work is neat and clean.Requires heavy equipment for handling and driving.

Piles of any size, length and shape can be made in advanced and used on site. Driven piles are not suitable in soils of poor drainage qualities.

There are also several advantages and disadvantages of reinforced concrete:AdvantagesDisadvantages

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

Shrinkage causes crack development and strength loss

Reinforced concrete, as a fluid material in the beginning, can be economically molded into a nearly limitless range of shapes.

The cost of the forms used for castingRCis relatively higher

Fire and weather resistance of reinforced concrete is fair.

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

Reinforced concrete can withstand a good amount tensile stress.The tensile strength of reinforced concrete is about one-tenth of its compressive strength.

Photos and DescriptionTemporary work:Temporary work which acts as place for the workers to relax and take shelter when the condition of the weather has become unfavourable.

Temporary work which acts as a rest room for the works as there are no public toilets near the vicinity of the construction site.

Temporary work for the drainage system as there are a lot of water around the site which has to be removed.

Scaffoldings which are temporary platforms for the workers which helps gain excess to the place and helps support them as well as the materials.

Plants and tools used: A crane is used in this construction site and its function is to move heavy objects, typically suspended.

Excavators are also found on this site which are used for earth digging and loading the excavated materials into the loading trucks to either for disposal or used later.

This welding generator provides electrical current to perform welding.

A bar bending machine is used to bend the reinforcement bars into all shapes and angles. We manage to catch a glimpse on how is the machine used on site

Construction work:The formwork which has already been placed on the column and is ready for concrete to be poured into the formwork.

An image of the concrete cover which is 35mm thick which has already been placed at the reinforcement bars for columns.

Stirrups, links and reinforcement bars which have been found on the site.

The concrete cover being made on site. We got to see how the concrete cover is made as they were just putting on the final touch for the concrete cover.

The links which already been tied to the reinforcement bars of the columun.

The concrete of the column which the formwork has already been taken off as the concrete has already been cured.

The reinforcement bars which are found in the walls.

Conclusion After the trip has ended and I have gained some new experience about how the real construction work is carried out, I realised that working at the construction site differs from just learning the theory of it. This is because we tend to omit the chance of bad weather conditions and the dangers of working at the site exist. This site visit gave me a great learning experience as it helped me in my imagination of how the tools are used for construction as well as allow me to see how a real construction site functions. They have also taught me the importance of safety as without it during site visit, a lot of accidents could occur and cause fatal injury. In addition, I have learned to identify various tools and construction materials we have asked our guide about the materials that piqued our interest as went along the way.

In conclusion, the site visit has helped me better my understanding on what the task of a quantity surveyor is at a construction site as well as the risks I will face in the future as a quantity surveyor. Overall, it was a great experience to go to an actual site which can help better my understanding as well as my imagination.

Objective: Understand the basics of the construction process. Understand the practical aspect of construction techniques in comparison to the theory aspect in books and its application on site. Exposure to actual working environment on site including uncertainty circumstances e.g. weather. Ability to communicate with the construction team members on site and to see the importance of teamwork in the building team. Witness the usage of construction equipment on site including mechanical plants. Explore and identify various types of building materials and technology on site. Awareness of the importance of safety on site and understanding of safety problems and site conditions. Recognize the items measurable for sub-structure and reinforced concrete frame works.
