Nowadays, building industry in Malaysia is an adult industry. The Malaysia structure sector is regarded as a catalyst for growth while its own performance assists as an sign to the nations economy. It really is supported by a fraternity of building player encompass programmers, contractors, building material and equipment, suppliers, manufacturers, financiers, regulators and other in the value chain (Lynda, 2006).
Formwork system is defined as the system of support for newly placed concrete including the mould or sheathing which contacts the concrete as well as aiding participants, hardware, and necessary bracing. Formwork system development has paralleled the development of concrete structure throughout the twentieth century. Both designers and contractors are aware of the necessity of building industry to be able to develop creative improvements from traditional method to improve quality and market when confronted with incoming structure industry difficulties.
Formwork is the major cost element for a typical multistory reinforced concrete building. It normally cost bank account around 40% to 60% of the cost of the concrete framework and for about 10% of the total building cost. Besides, the needs and dependence on the customers have sustained to grow which is necessary to find ways to create faster, cheaper and better quality building. Consequently, cost, production and quality of formwork system is variable by the system and materials choosing. Therefore, consider just as much as issue possible must be achieved before decide of choosing formwork.
Definition of Formwork
Formwork is a momentary boarding or sheeting erected to contain freshly located and compacted concrete until it has gained sufficient power to be self-supporting. The appearance of the completed concrete depends on the face surface and rigidity of the formwork. (Dictionary of Quarrying Conditions)
Formwork is the word directed at either short-term or long lasting moulds into which cement or similar materials are poured. Within the context of concrete structure, the falsework supports the shuttering moulds. (Wiki Answer)
Definition of Metallic Wall Form System
Steel is a materials generally hard, strong, durable, malleable alloy of flat iron and carbon, usually containing between 0. 2 and 1. 5 percent carbon, often with other constituents such as manganese, chromium, nickel, molybdenum, copper, tungsten, cobalt, or silicon, with regards to the desired alloy properties, and widely used as a structural material. Steel wall structure form system is one of the Engineered Formwork systems. (Answer. com)
This formwork is built out of prefabricated modules with a metal frame (usually material and aluminium) and covered on the application (concrete) area with material having the wanted surface framework (metallic, timber, etc. ). The two major benefits of formwork systems, compared to traditional timber formwork, are velocity of building (modular systems clip or screw alongside one another quickly) and lower life-cycle costs (barring major pressure, the frame is nearly indestructible, as the covering may need to be replaced after having a few - or a few dozen - uses, with regards to the applications).

Definition of Conventional Timber formwork
Conventional Timber formwork is also as known as Traditional timber formwork. The formwork is made on site out of timber and plywood. It is easy to produce but time-consuming for greater constructions, and the timber facing has a comparatively short lifespan. It really is still used thoroughly where the labour costs are less than the expenses for procuring re-usable formwork. Additionally it is the most versatile kind of formwork, so even where other systems are used, complicated sections might use it. (Nation Master. com)
Background of Research
Formwork is the one largest cost component of a concrete building's structural frame. The cost of formwork exceeds the price tag on the concrete or material, and in a few situation the formwork costs more than the concrete and steel combined. (Robert Leroy Peurifoy, Garold D. Oberlender, 1996)
For some structures, deciding the top priority of the formwork design allow to reduce the total shape costs by as much as 25%. This lowering involved immediate cost and indirect cost. Formwork is one of the key components in a job, it efficiencies in speed up the construction timetable in order to reduce interest cost, labour cost, equipment cost and etc during construction and early on complete for the job. (Formwork for Composition, 1996)
Formwork can be classified into two types, that happen to be regular timber formwork and system formwork. Regular timber formwork is the most typical kind of formwork, local companies already are familiar and get used with this method. System formwork is a fresh technology which introduced by Industrialized Building Systems. Predicated on insufficient knowledge on this technology, local service provider still refused to apply this method in job broadly. The primary reason they refused to applied this technology is cost of conventional formwork is much less than IBS or the technology of it.
Justification of Research
Presently, high climb building job is increasing in Malaysia. It consider as the primary tendencies in Malaysia's development policy. Steel wall membrane form system and normal timber formwork both is the key method to build a building. The contribution of the research will be explorer and examined in order to allow provided information to permit contractor in placing formwork design.
Problems Statement
Adapting the usage of Industry Building Systems in the building of high climb building acquired significantly offering advantages in various aspects, such as lowering the engineering cost, quickness of construction, minimizing manpower, green, improved site safety and better quality construction (Shaari 2004).
In order to get the benefits of IBS, during pre-planning stage, contractor must decide which type of formwork is the most suitable to be used in the task before contractor tender the project. For a expert, he will need to have well sensed in selecting the best formwork system to meet client's requirement.
Therefore, this dissertation will suggest and offer a information of contrast of priced at and productivity between metal shear wall structure form and conventional timber formwork for high go up building to contractor and consultant. Consequently, they are able to choose suited formwork system rather than increase quality and production of work, and save time and cost in the same time.
Objectives of Study
The aim of this research is to compare and find out whether steel wall membrane form system or conventional timber formwork is more desirable in high surge residential building engineering.
The specific goals were:
To analyze and cost and labor force required for both types of formwork system.
To define and review productivity of metal wall membrane form and normal timber formwork.
To review into different quality final result from the both formwork system.
To compare of costing and efficiency between steel wall structure form and regular timber formwork.
Scope of Project
This research will give attention to the local tasks that are using steel shear wall structure form and traditional formwork system. The study is limited to high-rise personal building building. Site stop by at the high rise residential building project will be perform in this research. One project will be sampled for this research with two different of formwork system for wall only.
Research Methodology
Desk Study
The data, information and reference materials will be collected through reference catalogs, journals, magazines, magazine and etc will be major tunnels for me personally to assemble information for my research title. Initial study is completed by thorough review on the literature on all the resources, to gain the essential understanding and surface theory on the relevant subject areas and area, which in turn be utilized in producing useful information and data.
