Summary
Prefabricated Prefinished Volumetric Construction (PPVC) is a modular construction method that enhances construction productivity and improves site safety through the integration of innovative technologies (Housing & Development Board, 2024). PPVC method utilizes volumetric modules that are prefabricated and completed with internal finishes, fixtures and fittings manufactured and assembled in an off-site prefabrication factory before being transported and installed at the project site. This allows off-site module manufacturing and on-site construction activities to proceed concurrently. According to the Building and Construction Authority (2024), this approach has the potential to increase productivity by up to 40%, delivering significant savings in both manpower and construction time. By streamlining workflows and reducing reliance on traditional on-site construction methods, PPVC not only accelerates project delivery timelines but also lowers overall project costs. In addition to enhancing productivity, PPVC significantly improves on-site safety. By shifting most of the construction activities to a controlled factory environment, PPVC reduces the number of workers required on-site, thereby lowering the risk of accidents and enhancing overall safety (Building and Construction Authority, 2024). The emphasis on better site safety minimizes the risk of injuries and fatalities, while also helping companies avoid legal complications and associated penalties.
Thesis
The prefabricated prefinished volumetric construction (PPVC) method demonstrates a transformative shift in the construction industry, outperforming traditional techniques through its ability to enhance productivity and safety on-site, proving its superiority as an efficient and risk-averse building solution.
