Abstract: Prefabricated Prefinished Volumetric Construction (PPVC) is a modular construction method that has an increasing trend in the construction industry due to the various benefits, which includes improved productivity, reduction of manpower on site, better site management and improved quality control on the produced products. The growing trend can be seen in Singapore as well whereby the Building Construction Authority (BCA) implemented the Design for Manufacturing and Assembly (DfMA) in the Construction Industry Transformation Map (ITM). Under DfMA, PPVC is included in it as it uses modules to construct a building in a more efficient and effective way. Building Information Model (BIM) widely used in the construction industry for the creation and management of data, construction and operation process (Autodesk, n.d.). However, modular methods have not been fully integrated in BIM thus there is insufficient support for modular buildings as the method is still considerably freshly widely adopted by the construction industry. This resulted in BIM unable to conduct effective translation and interpretation of information required by modular buildings and important information being lost during information exchange. Therefore, this research aims to conduct literature review on the existing softwares that are incorporated in the BIM systems and identify what was lacking in it that led to the insufficient support for modular buildings. Subsequently, the study will suggest and propose extensions to the Model View Definitions (MVD) to successfully integrate modular buildings into BIM. The study explored ways to improve on the current systems which include the creation of a modular process map, the identification of spatial and topological aspects required in modular buildings but not seen in conventional construction methods and lastly to extend the MVD specifically for modular buildings. Although the study did a review of literature and proposal of the extensions to the various systems, there are certain limitations such as the study is not being tested. Therefore, there are rooms for future study to test the development in the system.
