Abstract

Prefabricated Prefinished Volumetric Construction (PPVC) was defined as one of the construction methods that involves completing internal finishes, fixtures and fittings on free-standing, three-dimensional modules in an off-site fabrication or precast before having them shipped and placed on-site. Besides that, Prefabricated Prefinished Volumetric Construction (PPVC) was introduced by the Singapore Building and Construction Authority (BCA). The reason that the government of Singapore introduced this method to developers is to promote the high productivity construction process. Consequently, the main reason for doing this research is to increase the knowledge of the contractors in Malaysia by understanding PPVC construction methods. In this research, there are three main objectives to understand more about the PPVC construction method. Firstly, ascertain the benefits of using PPVC in the construction industry. Secondly, to understand the challenges of using PPVC during construction time. Thirdly, comparison between conventional methods and PPVC. Besides, the goal of this research is to increase contractors' understanding of PPVC construction techniques and to promote alternative construction methods. A quantitative research design is carried out through the literature review and questionnaire survey to participants who are involved in the construction industry. SPSS software is used to analyse the data using frequency analysis and inferential analysis. This analysis method shows contractors Grade 1 to Grade 7 involved in the construction industry’s opinion about the benefits of the PPVC construction method and the challenges of using the PPVC method for the current construction, and the comparison of PPVC construction method and conventional method (cast-in-situ). From the data analysis conducted in Chapter 4, most of the respondents that know about the PPVC agreed to the advantages of adopting the PPVC construction method but they also thought that there were lots of limitations where the construction cost might be higher compared to the conventional method. Moreover, the contractor also supported a comparison of the PPVC construction method and the conventional method. These findings suggest that the adoption of the PPVC construction method offers new insights into the construction industry in Malaysia. This study comprises the body of knowledge in the field of industrialised building systems (IBS) and is an attempt to date to examine and assess the use of the PPVC method in the construction sector. In conclusion, most of the contractors choose the PPVC method rather than the conventional method due to understanding the PPVC and conventional method. As a result, the PPVC approach can be commonly used in Malaysian construction due to speeding up the construction process and also improving building quality compared to conventional methods that have many uncontrolled conditions.
