Industrialized Building System (IBS) has been introduced in Malaysia since the 1960s. The government has come out with varies strategic blueprint to push IBS as a national agenda. Unfortunately, the pace of adaptation of IBS is still slow and below the government’s target. Construction players are still facing various issues when adopting IBS particularly on contractual and procurement aspects; thus it contributes to the low adoption of IBS in Malaysia. Lack of provision in the Malaysia standard form of contract is one of the issues. There are six (6) significant clauses in the Malaysia standard form of contract that can be improved to make it more conducive to IBS construction approach. Therefore this research will attempt to investigate the factors of improvement for the six (6) significant clauses in the standard form of contract with IBS construction. A semi-structured interview was used in the data collection exercise. The study revealed that there are eleven (11) factors of improvement for the six (6) significant clauses in the standard form of contract with IBS construction approach. The findings will be useful in order to enhance the local standard form of contract to suit the IBS construction approach hence able to accelerate the adoption of IBS construction in Malaysia.
