Presents, building industry in Malaysia is a mature industry. The Malaysia building sector is regarded as a accelerator for growing while its ain public presentation serves as an index to the states economic system. It is supported by a fraternity of building participant encompass developers, contractors, constructing stuff and equipment, providers, makers, moneymans, regulators and other in the value concatenation ( Lynda, 2006 ) .
Formwork system is defined as the system of support for newly placed concrete including the mold or sheathing which contacts the concrete every bit good as back uping members, hardware, and necessary brace. Formwork system development has paralleled the growing of concrete building throughout the 20th century. Both interior decorators and builders are cognizant of the demand of building industry in order to develop originative inventions from traditional method to better quality and economic system in the face of incoming building industry challenges.
Formwork is the largest cost constituent for a typical multistory reinforced concrete edifice. It usually cost history about 40 % to 60 % of the cost of the concrete frame and for about 10 % of the entire edifice cost. Besides, the demands and demand of the clients have continued to turn and it is indispensable to happen ways to construct faster, cheaper and better quality edifice. Consequently, cost, productiveness and quality of formwork system is variable by the system and stuff choosing. Therefore, see every bit much as issue possible must be done earlier do the determination of taking formwork.
Definition of Formwork
Formwork is a impermanent embarkation or sheeting erected to incorporate newly placed and compacted concrete until it has gained sufficient strength to be self-supporting. The visual aspect of the finished concrete depends on the face texture and stiffness of the formwork. ( Dictionary of Quarrying Footings )
Formwork is the term given to either impermanent or lasting molds into which concrete or similar stuffs are poured. In the context of concrete building, the falsework supports the shuttering molds. ( Wiki Answer )
Definition of Steel Wall Form System
Steel is a material by and large hard, strong, lasting, ductile metal of Fe and C, normally incorporating between 0.2 and 1.5 per centum C, frequently with other components such as manganese, Cr, Ni, Mo, Cu, wolfram, Co, or Si, depending on the coveted metal belongingss, and widely used as a structural stuff. Steel wall signifier system is one of the Engineered Formwork systems. ( Answer.com )
This formwork is built out of prefabricated faculties with a metal frame ( normally steel and aluminium ) and covered on the application ( concrete ) side with stuff holding the wanted surface construction ( steel, lumber, etc. ) . The two major advantages of formwork systems, compared to traditional lumber formwork, are velocity of building ( modular systems cartridge holder or sleep together together rapidly ) and lower life-cycle costs ( excluding major force, the frame is about indestructible, while the covering may hold to be replaced after a few – or a few twelve – utilizations, depending on the applications ) .

Definition of Conventional Timber formwork
Conventional Timber formwork is besides every bit known as Traditional lumber formwork. The formwork is built on site out of lumber and plyboard. It is easy to bring forth but time-consuming for larger constructions, and the lumber facing has a comparatively short lifetime. It is still used extensively where the labor costs are lower than the costs for securing re-usable formwork. It is besides the most flexible type of formwork, so even where other systems are in usage, complicated subdivisions may utilize it. ( Nation Master.com )
Background of Research
Formwork is the individual largest cost constituent of a concrete edifice ‘s structural frame. The cost of formwork exceeds the cost of the concrete or steel, and in some state of affairs the formwork costs more than the concrete and steel combined. ( Robert Leroy Peurifoy, Garold D. Oberlender, 1996 )
For some constructions, make up one’s minding the precedence of the formwork design allow to cut down the entire frame costs by every bit much as 25 % . This decrease involved direct cost and indirect cost. Formwork is one of the chief constituents in a undertaking, it efficiencies in accelerate the building agenda in order to cut down involvement cost, labour cost, machinery cost and etc during building and early complete for the undertaking. ( Formwork for Structure, 1996 )
Formwork can be categorized into two types, which are conventional timber formwork and system formwork. Conventional lumber formwork is the most common type of formwork, local contractors are already familiar and acquire used with this method. System formwork is a new engineering which introduced by Industrialized Building Systems. Based on deficiency of cognition on this engineering, local contractor still refused to use this method in undertaking loosely. The chief ground they refused to use this engineering is cost of conventional formwork is much lower than IBS or the engineering of it.
Justification of Research
Soon, high rise edifice undertaking is increasing in Malaysia. It consider as the chief tendencies in Malaysia ‘s development policy. Steel wall signifier system and conventional lumber formwork both is the chief method to build a edifice. The part of this research will be explorer and analyzed in order to let provided information to let contractor in puting formwork design.
Adapting the use of Industry Building Systems in the building of high rise edifice had significantly giving advantages in assorted facets, such as cut downing the building cost, velocity of building, minimising work force, environmentally friendly, improved site safety and better quality building ( Shaari 2004 ) .
In order to obtain the advantages of IBS, during pre-planning phase, contractor has to make up one’s mind which type of formwork is most suited to be usage in the undertaking before contractor stamp the undertaking. For a adviser, he must hold good sensed in choosing the suited formwork system to fulfill client ‘s demand.
Therefore, this thesis will propose and supply a item of comparing of bing and productiveness between steel shear wall signifier and conventional lumber formwork for high rise edifice to contractor and adviser. Consequently, they are able to take suited formwork system alternatively of addition quality and productiveness of work, and salvage clip and cost in the same clip.
Aims of Study
The purpose of this research is to compare and happen out whether steel wall signifier system or conventional lumber formwork is more suited in high rise residential edifice building.
The specific aims were:
To analyse and cost and labour force required for both types of formwork system.
To specify and analyze productiveness of steel wall signifier and conventional lumber formwork.
To analyze into different quality result from the both formwork system.
To compare of bing and productiveness between steel wall signifier and conventional lumber formwork.
Scope of Undertaking
This research will concentrate on the local undertakings that are utilizing steel shear wall signifier and traditional formwork system. The survey is limited to high-rise residential edifice building. Site visit to the high rise residential edifice undertaking will be carry out in this research. One undertaking will be sampled for this research with two different of formwork system for wall merely.
The information, information and mention stuffs will be collected through mention books, diaries, magazines, newspaper and etc will be major tunnels for me to garner information for my research rubric. Initial survey is carried out by comprehensive reappraisal on the literature on all the resources, to derive the basic apprehension and land theory on the relevant subjects and country, which so be used in bring forthing utile information and information.
Internet is a major tool to let me finds out the information about steel shear wall signifier and traditional lumber formwork. It besides enables me to acquire the latest information which is related with my thesis.
Throughout site visit, it let me to understand the method of the building in apply both different types of formwork in item. Interview will be transporting out during the building site visit. The people to be interview included contractors and other relevant party.
Case survey about steel and timber formwork system used in high rise residential building will be carried out. Interview will be carried out during the building site visit. The people to be interview included contractor, undertaking directors and other relevant party.
