Construction site in Shah Alam

This is a report on a site visit to a construction site. This is an assignment that related to three modules which are Measurement 1, Construction Technology 1 and Building Material. The construction site visit was organized on 23rd November 2016-Wednesday by our lectures. The construction site named Taman Impian Murni and it is locate in Shah Alam Selangor. This project is residential houses. There are 42 unit double storey terrace house & three storey terrace house. The purpose of the site visit was simple which is we needed to understand and visualise the theory that lectures taught in class. This is a great opportunity to student to gain some construction knowledge for the preparation of their future career. 3|Page

This site visit is organized on 23 rd November 2016. A total of approximately approximatel y 50 students  join this site visit. Before Before we went for the site visit, our lectures gave us a briefing about the safety precautions that we should be alert of we enter the construction site. On the day we visit, we gather outside the construction site at 9.00am.We went there by carpooling with our friends. This journey take around 30 minutes by car from Taylor’s University Lakeside Campus. There are 2 to 3 store y terrace house comprises of 4 to 6 bedrooms with 3 to 4 bathrooms. The range of the layout is between 1950 square feet to 2683 square feet. Taman Impian Murni has a variety of shopping amenitie, schools, hospital accessible for the convenient of their residence. Such as SK Bukit Kemuning 2, SMK Bukit Kemuning, SJK (C) Chung Hwa, Jusco Bukit Tinggi, Econsave Bukit Kemuning and Columbia Asia Hospital.

While we reach the construction site, the management give each of us a safety helmet as a head protection to avoid any accident happen in construction site. They need to ensure we all properly attired with safet y helmet and covered shoe to protect ourselves  before we entering the site. Safety is the most important part in the construction site. Whole surrounding of site was covered by vertical hoarding. A short brief about the  project was given by b y Mr Lim before we start the tour around arou nd the site. We all separate to 2 groups and start the tour around the construction site.

Mr Lim who in charge of our site visit explain a lot of information about this project.

Once we go through the construction site, we can clearl y saw a few temporary works installed.

Description Board Project information sign board shown in front of the main entrance.

Precaution board Precaution board were well placed at the main entrance as a reminder. Everyone in the site is required safety equipment to prevent accident.

Hoarding The construction site is fenced by vertical hoarding. Hoarding is used to stop unauthorized  person access to site. It is consider a dangerous act if you go into construction site without permission.

Accommodation Temporary accommodation for construction workers on site.

Material Storage Pre-cast concrete  bricks are well stacked on the floor. 50kg Portland composite cement bags properly stored in pallet form with proper height and correct stacking.

Fabric reinforcement that place in floors, and foundation slabs stored  properly at the site to use later.

False Work False work is actually supporting your column so your formwork does not fall. Mr Lim they  just finish casting one or two week ago so they start moving the formwork.

Formwork Formwork is the term given to either temporary or  permanent moulds  permanent moulds into which concrete which concrete or similar materials are poured. Formwork is actually what the concrete formed. This is timber formwork for concrete column. It is economical, light weight and easy to install or remove. 8|Page

Scaffolding A temporary structure used to support a work crew and materials in construction used  by workers while building, repairing, or cleaning the  building.

This project actually done with piling and covered by strip footing. Strip footing have two function, it act as a cap and act as a beam (ground beam).

Pile foundation is a deep foundation which is used in this project. Pile foundations are the part of a structure used to carr y and transfer the load of the structure to the bearing ground ground located at some depth below ground ground surface. Material of piling can be steel, timber or concrete and it driven into soil and to support foundation, retaining walls or other structures. Advantages of pile foundation is it suitable for all type of soil.

Concrete Cover Concrete cover, in reinforced concrete, it  placed between the surface of reinforcement and the outer surface. Concrete cover for steel st eel bar is much necessary to protect the steel against corrosion and to provide resistance against fire. Concrete cover are usually  pre-fabricated and use it piece by piece. The workers is measure the thickness of the concrete cover and make sure it is flat with concrete cover which placed upper .

Clay Bricks & Concrete Bricks The reason why we always use clay brick in between the houses and we use mason brick within the houses itself .In Malaysia law, fire fighting need two hours and clay bricks can actually get to that level because it i t minimum thickness is 150m. Concrete bricks also have same function with clay bricks but concrete bricks is l ess costly. Concrete bricks noise insulation and fire fighting are not as well as clay bricks.

Concrete Stairs Concrete stairs are ideal for the construction of high quality private and residential stairways. Maintenance free service and excellent durability are the benefits of concrete stairs.

Lintel Lintel is a horizontal a horizontal support of concrete across the top of a door or window. So that the load will not go on the door or window frame itself. If the load go on the door frame, it will melt back after a period of time and the frame will deform.

Column A column or pillar in Architecture and Structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements  below. Typically cylindrical and made of stone or concrete.

Beam A beam is a structural element that is capable of withstanding load primarily by resisting against bending. The bending force induced into the material of the beam as a result of the external loads, own weight, span and external reactions to these loads is called a bending moment.

Suspended slab

 Non Suspended Slab

Suspended slabs are slabs that are not in direct contact with the ground. ground. The load directly distribute to beam at that side and move down to the column and then strip pilling after that goes down to your pile.

It called non suspended beam because it is partially partiall y supported by the ground. So half of the load are distributed to the ground directly while another half are distributed to the beam. This means that the reinforcement and loading here much less when compare to the above (upper floor sla slab .

Mr Lim said expose the reinforcement bars in ground beams and then concrete only about ¾ of the ground beam. Next, tie the mesh fabric reinforcement (BRC) of the slab together with the exposed reinforcement  bars of the ground beam before concreting the slab. In terms of civil engineering, ground floor loads are distributed to the ground level, so there will be less reinforcement required and the sizes of BRC might be reduced, thus allows cost saving compared to the suspended floor slabs.

Scraper drain There is a drop on the up stand beam and it actually help you to move the water from one side to the floor track itself.

Ventilation pipe Ventilation pipe used for release smelly gas from above the roof.

Double brick cavity wall This houses use double brick cavity wall. Double brick cavity wall consists of two layers la yers of brick with a cavity in between separating the two leaves of masonry bricks. As brick is an absorbent material, it can draw rainwater or moisture into the construction. Hence, the cavity serves as drainage to  protect the construction from the external elements. Double brick cavity wall gives better performance in thermal, acoustic and prevents moisture being transferred directly from the outside wall face to the interior of the building as compared to conventional single skin brick wall construction.

This is your most conventional construction that and it actually uses cast in-situ. Cast in-situ means everything will be cast in the spot after you construct the formwork and false work. However, that is another method which is very trending right now called IBS system they build your house like lego everything is already  pre casted and pre moulded and you you can actually duplicate it easily. Basically, concrete is very strong in the compression but it is very brittle and very weak in tensile strength. Steel is very strong at both but steel is very expensive so we can’t build whole building by steel. We use this steel rebar to act as skeleton of the  backbone of concrete to actually to give tensile strength. It partly used to reinforce and partly used to support. Stirrup and Link Stirrup a reinforcement a reinforcement used to resist shear resist shear and diagonal and diagonal tension stresses in a concrete structural  concrete structural member. Link is used to hold the longitudinal bars in columns in position, preventing them from buckling outward by  bursting the thin concrete cover.

Pre checking before poured concrete

First, you need to measures the consistency and workability of the concrete by slump test. Second, you need to make sure concrete cover placed properly before poured concrete. Third, check structural drawing whether reinforcement bar placed properly and correct. If you not reinforce formwork carefully the supporting member will lose when you tied up. If it loose, the concrete will flow out. And contractor need to remove concrete slab because concrete is harden very fast. You will have a lot of honey comb and loose joints. You also need to pay extra money for restructure. It is very expensive to pay for carbon fibre reinfor ce that why you need to pre checking.

Concrete Mixer A concrete mixer is a device that combines cement, combines  cement, aggregate  aggregate such as sand or gravel, and water and water to form concrete. form concrete. Special concrete transport trucks transport trucks are made to transport and mix concrete up to the construction site. They can be charged with dry materials and wat er, with the mixing occurring during transport. Excavator Excavator is the machine that can excavate the soil of soil of various types forcefully and then using hydraulic force is generated and utilizing this force  bucket is pull back towards the machine. Excavators are used for earth digging, loading trucks, trenching and breaking  previous layers of highways and and loading.

Crane A crane is a type of machine, generally equipped with a hoist a hoist rope, wire rope, wire ropes or  chains, and  chains, and sheaves,  sheaves, that  that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. In the construction the construction industry for the movement of materials and in the manufacturing industry for the assembling of  heavy  heavy equipment. 15 | P a g e

This is my first time enter a construction site. After this site visit, I gain extra and valuable knowledge which can’t learn in theory class. I also know the basic of how a building be constructed .This is a chance for students to experience actual working environment as a quantity surveyor in site through this visit. First, I know the important of safety while we in construction site .Lectures and Mr Lim who in charge of this visit always remind us he important of safety. We are required to wear safety sa fety helmet and covered shoe to avoid the happening of accident while we in the site. There are also have precautious board placed at the entrance of site to remind us. We also learn to identify various type of building materials and obverse some construction technology while walking through construction construction site. Besides, we can clearly see how the equipment and machinery work in side. Moreover, I also more clearly in the principle of measurement while I actually see where the reinforcement placed. I am not clear in what concrete cover function and where it placed before this visit but after Mr Lim explain in the site ,I can clearly know what is it. Ms Ang also show us some principle of measurement on site. I am very thankful to have opportunity go for this site visit .It really benefits to fresh students who just semester 1 like me. It increase my knowledge and experience .I hope that I have more chances to visit other sites after this.
