Is a system where all elements of industrial production of components to bespecific designs for specific projects. The system does not allow for theinterchangeability of components from different factories.

Current systems in Malaysia which supports the usage of Industrialised BuSystems (IBS) are mainly a close system, where each component manufachave their own propriety building systems to be adopted in the project.

The IBSs used in Malaysia belong mainly to closed systems. The building ifrom components specifically designed for and applicable to the particular b

system.A closed system can be classified into two categories :

production based on clients design

production based on manufacturers design.

The government has embarked the IBS Roadmap 2003-2010 that outlines strategiesto promote the use of IBS in Malaysia.

The government has encouraged the use of IBS for the construction of newgovernment quarters

Closed systems can overcome the requirement of many standardised elemautomating the design and production process and sufficient demand for a of building such as school so that a mass production can be obtained.

Open building system

A building can use two or more systems

It allows openness to selects supplier ofthe components where everybody can bidto produce lower price of components.

Allows the precaster to produce a limitednumber of elements with pre-determinedrange of product and also maintainingarchitectural aesthetic value.

The cost of building components will bereduced in the long run where plenty ofoptions are available in the market

Closed building system

Does not allow for the interchangecomponents from different factorie

Can be classified into two categori

-production based on clients desig

-production based on manufacturedesign.

the production based on manufactureincludes designing and producing a unifof building , which can be produced withassortments of component.

The IBS in Malaysia promotes open system or hybrid system and encouragindustry participation compared to the prefab closed system where only limindustry companies can participate.

Low standardisation of components

only a limited choice between a few types of houses for each project (otherproduction series are to small)

monotony of large sites

monopolistic positions for producers and large scale contractors.


10/24


11/24

Size of project is large enough

to allow for distribution of design and production costs

Large repetitive element and standardization

a novel prefabrication system can overcome the requirement of many standardisby automating the design and production process.

Sufficient demand for a typical type of building to obtain the mass productio

Intensive marketing strategy by precaster

to enlighten the clients and designer the potential benefit of the system

LACK OF COOPERATEBETWEEN CONTRACTOR-

MANUFACTURER involve many parties led to the involvement of IBS contractors and manufactureonly after the design phase (CIDB,2005). CIDB (2007) reported that the need ofredesign on IBS components, which, incurred additional cost is due to lack ofintegration among relevant players. Further, Kamar et al., (2009) is in the opiniothat the pre-caster, designer and contractor firm should be integrated as early apossible in order to ensure the success of IBS. Integration deficiency in IBSconstruction has led to ineffective communication and lacks understanding amo

the stakeholders (Kamar et al., 2010). On top of that,

Nawi et al., (2007) and Kamar et al., (2009) highlighted the construction industryrequires contractors to be system integrator and process coordinator in managithe process from the production line to the site.


15/24

The requirement of using skilled labour and machineries indirectly w

incur the cost during theerection of IBS components. The components itself, for instanceconcrete panels, are heavyand difficult to align, which, may lead to the problem of improperassembly, leakage and crack in thefuture (Rahman & Omar, 2006).

Meanwhile, the connections also are not flexible enough to allowchanges during mid-construction (Sadafi et al., 2011).

According to Pan et al., (2004) the site specifics orconstraints also caused problems in the IBS construction process sIBS components required additional space for storage, mobilizationcirculation of machines and equipments.


16/24

The complexity of lift, normally

increases with the increase in level

of IBS usage. Transportation

consideration will give impact on

construction schedules, site

design, crane cost and availability

of designing the plan itself.

As discussed by Haas & Fagerlund, (2002) transportation issuerevol

the issues of size and weight limitations, route restrictions, permitting

the availability of lifting equipment. When the components reach theconstruction site, it requires additional lift planning.


17/24

When selecting IBS as an option, it is necessary to understand theextensive coordination required prior to construction operations, fo

instances coordination of design, transportation, tracking, and

installation to ensure successful implementation. Apart from that,

adjustments in the work breakdown structure, terminology, drawing

progress measurement, scheduling for materials management and

supply chain scheduling should also take into consideration. With tincreased of coordination required for the construction operations,

needs of effective communication becoming vital for the distributio

information regarding decisions, designs, transportation requireme

and schedules.


18/24

Since the IBS is not practically use in construction in

Malaysia,

Many labours will face dificulties and delay while

doing construction. They need to understand the

technology of construction system. Not all the system

used for every building is the same. Any building will

differs have significant material and method to install.

They have to undergoes proper training before begin.


19/24

BUILDING SYSTEMCOMPONENTOne of the success factors in IBS usage is the

standardization of components. To date the lowcomponents standardization prevents the samecomponents to be used for other projects (Hashim &Kamar, 2011). Onyeizu et al., (2011) opinied thatarchitects, engineers and contractors regard

standardization of building components as the key factoaffecting IBS and design innovation. The effect of lowstandardisation will increase the initial cost due to thedesign cost and moulding which cannot be used foranother project (Hamid et al., 2008
