Productivity rate for industrialised building system project

Abstract

In line with development of the technology, the Government of Malaysia has taken the initiative by emphasizing the application of the Industrial Building System (IBS) in every project implementation in Malaysia. However, the acceptance of this technology in Malaysia is relatively low with few projects being constructed with precast components. Jabatan Kerja Raya Malaysia (JKR) has completed thousands of projects every year for various ministries in Malaysia, but there is still lack of data to refer on the productivity rate of the construction activities especially for IBS project in Malaysia. Due to this, a case study has been carried out to establish the productivity rate of execution of IBS components in construction project. The productivity rate in this study is focused mainly on the installation process. The selected project for this case study is Cadangan Pembinaan Semula dan Menaiktaraf Sekolah Daif Menggunakan Kaedah IBS Di Semenanjung Malaysia (Fasa1) Tahun 2018 Bagi Negeri Sembilan, di Sekolah Kebangsaan Seberang Batu Hampar, Negeri Sembilan Darul Khusus. There are three (3) objectives for this paper where the first one is to identify installation process of IBS component insist of column, wall and roof based on project?s record. Second objective is to determine factors that affect the productivity rate of IBS project during construction. Referred to project?s monthly report, the factor that affected the productivity rate of IBS project during construction are skills and knowledge of handling IBS project. Cost and finance also contributed to the factor that affected the productivity rate of IBS project. Several counter measure has been proposed to tackle these issues. The third objective is to estimate the productivity rate on execution of IBS components which involved column, wall and roof structure. Collected data were analyzed using a formula consist of total area coverage of IBS component divided by manhour required to complete the work. Based on the findings, the productivity rate by blocks for column, wall and roof are 0.76 m2/manhour, 1.20 m2/manhour and 2.36 m2/manhour. From this case study, the findings can be used as a reference productivity rate study as well as estimation of the IBS projects implementation in the future.
