| Summary: | Building Information Modelling (BIM) is an important technology enabler for digital transformation in the construction industry. It is a highly collaborative process that allows architects, engineers, contractors, and other construction professionals to plan, design and construct a building or facility in the form of a 3D model based. Despite the advantages of BIM, the adoption level of BIM among contractors in developing countries, particularly Malaysia, remains lower than expected. This is due to the fact that the contractors have no profound understanding of BIM and its’ requirement. Hence, the aim of this paper is to explore the uses of BIM focusing on the planning-to-design stage based on the BIM execution plan from the perspective of the BIM-based project contractors. The data was gathered through semi-structured interview sessions with the six (6) respondents and evaluated using a content analysis approach via the software ATLAS-Ti 9. The findings showed that the planning phase via 4D modelling was remarked as the upmost significant use in the planning-to-the-design stage. The 4D modelling involves time-related information, installation periods and sequences, workflow rescheduling, construction visualization, material optimization, project coordination, and project safety. This study also showed that the PWD DB, PWD203A and PAM2018/2006 contract has been used by the BIM-based project contractors. Thus, the results of the study provide insight into the BIM-based project contractors’ that have taken into consideration the uses of BIM for future BIM-based project contractors. © 2024, Construction Research Institute of Malaysia.
