UNDERSTANDING THE PREFABRICATED PREFINISHED VOLUMETRIC CONSTRUCTION PROCESS USING A SIMULATION STUDY

Abstract

Prefabricated Prefinished Volumetric Construction (PPVC), a novel off-site construction method promoted by the Singapore government in recent years, has started gaining worldwide attention. Some of the most significant advantages of PPVC over conventional construction include reduction of manpower and cycle time, improvement of safety and mitigation of congestion during construction. Nevertheless, as the development and application of PPVC is still in its infancy, the underlying processes and its corresponding limitations have yet to be mapped and explored. Therefore, the objective of this thesis is to propose a comprehensive process map of PPVC project, through an in-depth case study, aiming to uncover the key constraints existing in PPVC process and explore possible mitigation strategies using state-of-the-art technologies accordingly for the sake of developing an automated non-contact quality assessment system of PPVC mold using 3D point cloud data and Building Information Models (BIM).
