1. IBS in Malaysia has begun in early 1960’s when Ministry of Housing and Local Government of Malaysia visited several European countries and evaluate their housing development program (Thanoon et. al. 2003).
2. After their successful visit in 1964, the government had started first project on IBS aims to speed up the delivery time and built affordable and quality houses. About 22.7 acres of land along Jalan Pekeliling, Kuala Lumpur was dedicated to the project comprising seven blocks of 17 storeys flat there are 3000 units of low-cost flat and 40 shops lot. This project was awarded to Gammon and Larsen Nielsen using Danish System of large panel of pre-fabricated system (CIDB, 2003).
3. In 1967, the second housing project initiated by the government of Malaysia, the project comprising a 6 block of 17 storey flat and 3 blocks of 18 storey flat at Jalan Rifle Range, Penang. The project was awarded to Hochtief and Chee Seng using French Estoit System (Din, 1984; CIDB, 2003 and Sarja, 1998).
4. With reference to the two pilot projects, a performance comparison between the IBS system and conventional system has been carried in terms of cost, productivity, and quality. It was discovered that the first pilot project incurred 8.1% higher cost than a similar building using conventional construction method, while the second project was 2.6% lower.
5. In term of construction speed, both projects required 27 months to complete, inclusive of time required to set up the recasting factories. The quality of building finishes was also found to be better than the conventional construction method. In conclusion, the overall performance of an IBS is competitive with the conventional construction method.
6. Among the earliest housing development project using IBS was Taman Tun Sardon, Penang. IBS pre-cast component and system in the project was designed by British Research Establishment for low cost housing in tropical countries.
7. Nonetheless, the building design was very basic and not considering the aspect of serviceability such as the need of wet toilet and bathroom (Rahman and Omar, 2006).
8. Between 1981 and 1993, Perbadanan Kemajuan Negeri Selangor (PKNS) a state government development agency acquired pre-cast concrete technology from Praton Haus International based on Germany to build low cost house and high cost bungalow in Selangor (CIDB, 2003).
9. Other large panel systems in Malaysia include Taisei Marubeni System (Japanese system) used in Shah Alam, Ingeback System (Swedish system) in high-rise building (Sarja, 1998). IBS was implemented in Taman Maluri, Pandan Jaya and Wangsa Maju using metal-formwork system (Sarja, 1998)
10. The usage of steel structure as part of IBS, first gained attention with the construction of 36 storey Dayabumi complex that was completed in 1984 by Takenaka Corporation of Japan (CIDB, 2003).
11. IBS research and promotion was pioneered by Housing Research Centre (HRC), Universiti Putra Malaysia. HRC developed local IBS system Interlocking load bearing hollow-block building (Putra Block) has won the prestigious ‘Geneva Gold Medal’ award for innovation.
12. HRC were also engaged with the National Affordable Housing research program with the Ministry of Housing and Local Government in 2001.
13. In 1999, Construction Industry Development Board (CIDB) Malaysia formed the IBS Steering Committee in the effort to bring to the fore all the IBS related issues in a framework and IBS Strategic Plan 1999 were published
14. Today, the use of IBS as a method of construction in Malaysia is evolving. Many private companies in Malaysia have teamed up with foreign expert from Australia, Netherlands, United State and Japan to offer pre-cast solution to their project (CIDB, 2003).
15. In addition, more and more local manufacturers have established themselves in the market. Pre-cast, steel frame and other IBS were used as hybrid construction to build national landmark such as Bukit Jalil Sport Complex, Lightweight Railway Train (LRT) and Petronas Twin Tower.
16. 131 manufacture registered with CIDB to date with 200 IBS products available in the market (CIDB Orange Book Volume 3). Over 800 registered IBS contractor available in 2007 (CIDB Orange Book Volume 1).
