16 Challenges and Lessons Learn Along the Construction Industry Value Chain 3,252 architects engineers 2,081 quantity surveyors Designers Challenges Not a popular choice among designers because IBS perceived as limiting creativity in design 63,977 contractors Contractors / Builders/ Owners Current exemption from levy cannot cover additional cost for developers 118 manufacturers IBS Manufacturing Base Lack of volume and economies of scale due to non-standardisation of designs Construction Site IBS Value Chain Lack of on-site specialised skills for assembly and erection of components Lack of IBS design knowledge among designers Proprietary systems make it hard to be adopted by designer Insufficient push factor from the end buyer for IBS properties (except for GoM sector). Unlike Green Buildings where buyers knows the benefits and enjoy tax break for such buildings Lack of quality control in smaller IBS manufacturers Lack of local R&D, support services, technologies and testing labs Lack of innovative products that can enhance aesthetic values of buildings Lack of people with IBS project management skill which requires more logistics planning & coordination with IBS suppliers (i.e on-time delivery) Additional cost in hiring special equipment and machinery in implementing IBS (i.e heavy duty lifting crane) The challenges faced have remain unchanged despite being repeatedly voiced by the industry stakeholders during surveys, forums and workshops through-out the years indicates problems need to be resolved at the root cause level Standardisation Issue Skills Issue

18 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

20 Structural Category of IBS Based on CIDB Group 1: Pre-cast Concrete Framing, Panel and Box Systems Includes precast concrete columns, beams, slabs, walls. 3 D components e.g. balconies, staircases, toilets, lift chambers, refuse chambers. Lightweight precast concrete and permanent concrete formworks.

21 PRE- CAST CONCRETE COMPONENTS Balcony Beams

22 Group 2: Steel Formwork Systems E.g.: tunnel forms, tilt-up system beams/columns molding and Permanent steel formworks (metal decks)

23 Tilt-up system and permanent steel formworks

24 Group 3: Steel Framing Systems Steel framing system e.g. steel trusses, columns, beams and portal frame system

25 Group 4: Prefabricated Timber Framing Systems Prefabricated timber framing systems consists of prefabricated timber trusses, beams and columns.

26 Group 5: Block Work Systems Block work system includes interlocking concrete masonry unit (CMU) Lightweight concrete blocks

28 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.

29 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.

30 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.

31 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

32 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.

33 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.

34 FUTURE DEMAND ON IBS IN CONSTRUCTION INDUSTRY (source CIDB) The Government sector will enforce the use of IBS components by 70% for projects worth RM10 million and above, as in the Surat Pekeliling Bil 7./2008 for the period of implementation IBS IBS Track for Roadmap the Public Sector IBS Penetration high% 70% scoring for all RM10m projects Government Sector Private Sector Policy Driven Fast Track option for government projects 50% scoring for all RM10m projects Policy Driven low Sporadic developments using IBS Pekeliling Flats Dayabumi IBS Strategic Plan Treasury Circular 2005 Treasury Circular s today 58 IBS Projects Applied for Levi Exemption 2012 Policy (Private Sector) score mean achievement of IBS incentive of IBS 2015 Time 2020
