Signboard

The construction industry has long been considered as a difficult, dangerous and dirty occupation due to the high number of accidents, injuries and deaths. Construction workers are exposed to different risks.

➔ Every site must have signage that shows health and safety message.A simple but effective warning notice should be placed in conspicuous position to warn the workers and public.

➔ Reason : To deliver important bit of information to people and warn them about hazard that could be happen in construction site.

➔ Besides, project signboard have to place in front of the site as well. It provide the information of building work and who the licensed people are doing the work. The sign provides information about who is working and their contact.

4.0 FOUNDATION BENJAMIN TAN ZI HERN

➔ A lower portion of building structure that transfers its gravity loads to the earth.

➔ Broken into two categories: shallow foundations and deep foundations.

Determine the foundation type based on:

Structural LoadingIn low rise building with large span, the extent of loading is relatively modest,so shallow foundation is chosen. Deep foundation is selected in high-rise building with short span has high loads.

Soil ConditionWhen soil close to the surface is capable of supporting structure loads, shallow foundations can be provided. Deep foundations are suitable when ground close to surface is not capable of supporting structural loads, and hard strata is needed.

Time FactorTime for pile installation in construction plan affect which type of foundation to be used. For example, overall construction for this site takes 23 months to complete. Foundation takes 2 months..

Two types of foundation systems are shallow foundation and deep foundation.

Shallow foundationStrip footingsA continuous strip of concrete that serves to spread the weight of a load-bearing wall across an area of soil.

Masonry or concrete wall

Reinforced concrete strip footing

Raft footingsA thick concrete slab reinforced with steel which covers the entire contact area of the structure like a thick floor.

Pad footingsA form of spread foundation formed by rectangular or square concrete ‘pads’ that support localised single-point loads such as structural columns, groups of columns or framed structures.

Deep foundationTypes of pilesPile may be classified as either End bearing or Friction piles, according to the manner in which the pile loads are resisted.

End bearing piles Friction piles

The shaft of an end bearing pile passes through soft deposits until it meets a suitable base on bedrock, dense sand or gravel.

A friction pile obtains its support mainly by the adhesion or skin friction of the soil on the surface of the shaft, usually firm clays.

Types of displacement piles

Precast reinforced concrete pilesThe piles are in circular, square, rectangular or octagonal form. They are cast and cured in a casting yard and then transported to the site for driving.

Steel preformed pilesThis type of piles are made of sectors in the form of H, X or of thick pipes. They are suitable for handling and driving in long lengths.

Composite pilesComposite piles are made up of a combination of different materials. Steel piles are used above the ground water level, while timber piles are installed below ground water level to prevent insect attack and decay.

Driven in situ/ Cast-in-place pilesThe most type commonly used for foundations due to the great diversity available for pouring concrete and the introduction of the pile into the soil. Two ways of installing the piles are driving and drilling.

➔ R.C.C beams are designed to act together with longitudinal and web reinforcement in resisting applied forces.

➔ Subjected to bending moments and shear. ➔ Due to the vertical external load, bending compresses

the top fibers of the beam and elongates the bottom fibers.

➔ The strength of R.C.C beam depends on the composite action of concrete.

RCC beams are being used due to their high compressive strength in general, also, high resistance to fire and weather.

FORMWORK:

Formwork functions as a mould for workers to pour concrete in. Formwork will later be removed when the concrete has set and dried.

Construction tolerance is a guideline for contractors to ensure the built structures are within specific range.

In construction site, the measurement of built structure may differ to architect’s drawing due to workmanship, materials, and environment factor. Therefore a standard range of tolerance is set to prevent out of proportion buildings.

The standard tolerance for Malaysia’s construction industry is 14mm, although some stricter architects limit up to 8mm, which is harder to achieve for contractors.

Column in site differs from the

drawing by 12mm, therefore, it’s “tolerated”.

A wall is a structure that defined as an area, carried a load, or provides shelter or security. Wall construction divided into two categories, which are framed walls and mass walls. Framed walls is called as a non load bearing wall, which had three or more separate components like timber, concrete or metal. Mass wall will be load bearing wall, which using solid material like masonry wall. For example, brick or stone.

WALL:➔ Protection & security➔ Divided into different space in one area➔ Carried load to support upper floor➔ Sound insulation➔ Fire resistance➔ Lower energy bills

TYPE OF WALL:LOAD BEARING WALL:➔ Carried load from foundation

to upper floor➔ This wall construct with

reinforcement steel bar or join with column.

NON LOAD BEARING WALL:➔ This wall does not support

load, because the building itself had concrete beam and columns on it to support the load from upper floor.

A stairway, staircase, stairwell, flight of stairs, or simply stairs is a construction designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Special types of stairs include escalators and ladders. Some alternatives to stairs are elevators, stairlifts and inclined moving walkways as well as stationary inclined sidewalks.

CONCRETE STAIRCASE:

➔ Designed by a qualified Engineer as it requires careful analysis of load, span and support conditions. ➔ Common use in multi-storey building.➔ May be either cast in-situ or pre-cast. ➔ Railing may be timber, glass, metal or concrete.➔ Riser and tread finishing can be timber or metal or any other type finishing. ➔ Heavily reinforced.

The site has used reinforced concrete stairs cast in-situ which is also double winder for this project with the half landing style. By using the material, concrete for the stairs is to make it more stable and long lasting for the building. Beside that, concrete staircase also have thermal insulation, low maintenance cost and better fire resistance.

STAGE FIVE: Forming and pouring concrete steps.

➔ Saw cut your form lumber and finish corners: Sawcut all but the bottom step forms at a 45- degree angle.This allows for finishing right up to the corner of the step.

➔ Attach step from liners: wish to create stone- like textures on the faces of concrete steps or a profiled edge, use polyurethane step form liners or foam forms, attaching them to the wood forms with finishing nails.

➔ Use form support to ensure the use of wood stakes to brace forms to prevent them from bowing outward as the concrete is placed.

➔ Vibrate the edge of forms: It’s importance to vibrate the face of the concrete forms to remove any honeycombs and voids from the concrete surface. Vibrating the forms bring the concrete paste to the surface to fill in any holes. Tap the wood forms with a hammer or use a palm sander to vibrate the freshly poured concrete.

➔ Remove forms the day of pour and customize: Remove the step forms and finish the corner of each step the day of the pour. This will allow use of concrete chisels to cut hand tooled joints and texturing skins on step faces and surfaces.

Rafters are a single piece of lumber that span from beam to beam or beam to wall or wall to wall. The may be sloped or flat. Although flat rafters are usually called joist.

Wood plank-and-beam roof systems are similar and both typically use same post or column structural grid for their support

Trusses rafter roof are pre-engineered and shop-fabricated monoplaner trusses

➔ Flat roof can efficiently cover a building of any horizontal dimension.v

➔ Low slope roofs require roll or continuous membrane roofing: some shingle and sheet materials may used on 3in2 pitches.

➔ Medium and high slope may be covered with shingles, tiles or sheet materials

The site used Skillion roof or known as Slanted roof. The site used the the method slanted backward which higher at the front.The reason it is apply in this project is because slanted roof allow the rainwater to flow backward to the drainage system.

8.0 SUMMARY GROUP//

8.0 SUMMARY

From this project, we gain a lot of knowledge about the construction process of a building. Construction is a vigorous process that involves a lot of parties. To ensure the construction is successful, effective planning and multitasking is crucial. For example, architect and contractor have to communicate well and plan about the project. This smoothen the progress of construction.

Besides, throughout the project let us understand that the construction can be more complex than we think. During the site visit, we are quite lost about the process but after doing some research it helps us to understand more especially those details process. We try to gather and simplify the information we get.

In a nutshell, we had learn what could not be confined in the class from the site. The construction process is very complicated. Every single steps or procedure are linked and important. It have to be carry out with caution and specificity. This is to ensure the final product is safe for the client and also community.
