USED OF IBS SYSTEM
• All building components such as wall, floor slab, beam, column and staircases are mass produced either in factory or at site under strict quality control and minimal on site activities
• Mechanization of the building processes
• Example of completed building in Malaysia HUKM, university Hospital, Selayang Hospital, Kuala Lumpur Tower, IKEA Damansara

IBS AS A SUSTAINABLE CONSTRUCTION
• Sustainable construction enable to:-
I. Save energy and resources, recycle materials & minimize the emission of toxic substances.
II. Harmonies with the local climates, traditions, culture & the surrounding environment.
III. Able to sustain & improve the quality of human life whilst at local & global levels.
IV. Saving and increase workplace productivity.
ADVANTAGES OF INDUSTRIALISED BUILDING SYSTEM (IBS)According to CIDB (2003), compares to conventional construction
method, the IBS has the following advantages:
i. Less construction time
• IBS requires less construction time because casting of precast element at factory and foundation work at site can occur simultaneously and the work at site is only the erection of IBS components. This leads to earlier occupation of the building.
ii. Cost savings
• The formwork of IBS components are made of steel, aluminum or other materials
that allows for repetitive use and this leads to considerable cost savings.
iii. Saving in labour
• When the IBS components are produced in factory, higher degree of utilization of machine is permitted and the use of labour will be reduced and lead to saving in labour cost.
iv. Less labour at site
• The use of IBS will reduce the construction process at site and consequently reduce the number of labour required at site.
v. Optimized use of material
• The utilization of machine during the production of IBS components lead to higher degree of precision and accuracy in the production and consequently reduce material wastage.
vi. Higher quality and better finishes
• An IBS component have higher quality and better finishes due to the careful selection of materials, use of advanced technology, better and strict quality assurance control since production in factory is under sheltered environment.
vii. Construction operation less affected by weather
• Faster project completion due to rapid all weather construction. The effects of weather on construction operation are less due to the fabrication of IBS components is done in factory while at site is only erection of the components.
viii. Flexibility• IBS provides flexibility in the design of precast element so that
different systems may produce their own unique prefabrication construction methods.
ix. Increase site safety and neatness• Utilization of IBS components leads to less construction process
especially wet work at site. This will lead to the neater site condition and increase safety.
x. Environmental friendly• The use of IBS will decrease the using of timber formwork on
construction project
DISADVANTAGES OF IBS
i. High initial capital cost• The initial capital cost of IBS is usually high. The initial cost
including the cost of constructing the factory, casting beds and support machinery. The cost effectiveness can only be achieved when undertaking large projects.
ii. Problem of joints• Water leakage is often the major problem in building constructed
using IBS. This problem is more obvious in Malaysia where raining occur rapidly through out the year.
iii. Sophisticated plants and skilled operators• The prefabrication system relies heavily on sophisticated plants,
which have to be well coordinated and maintained by skilled operators. Breakdown in any one section would hold-up the entire production line.
iv. Site accessibility
• Site accessibility is one of the most important factors of the implementation of IBS.IBS requires adequate sit accessibility to transport IBS components from factory to the site.
v. Large working area
• Building construction using IBS requires a large working area for the factory, trailers, tower-cranes and storage for the IBS components. Besides, most construction sites especially in cities are often congested and unable to provide the area required.
