BIM-ENABLED ASSESSMENT AND MITIGATION OF EMBODIED CARBON FOR PREFABRICATED PREFINISHED VOLUMETRIC CONSTRUCTION (PPVC)

Abstract

Considering the current focus on Global Warming and climate change in the world, there has been focus on controlling our carbon emissions levels in the world. In construction, there has been high levels of carbon emissions that are involved in the typical construction process. Hence, in the movement towards being more environmentally friendly, much focus has been placed to see if there are functional construction methods to cut down carbon emission levels produced in construction.

One such method suggested is Prefabricated Prefinished Volumetric Construction (PPVC), which is currently widely used in the industry in Singapore. This method has said to be efficient in carry out work, as well as reducing the wastage of unnecessary material, and to create better quality structurers as compared to traditional construction of cast-in-situ concrete on site. However, they have not been any study that could directly prove that construction method of PPVC does indeed reduce carbon emissions compared to typical construction.

Building Information Modelling (BIM) can model and simulate a planned building in a virtual space so that the users are able to visualise the building and its specifics. Other than the virtual draft, the model also measures the volume of material used in the model.

This dissertation will use the simulation of a residential building model and the “PPVC-version” of it, where we will be able to compare and see analyse the difference and the impacts of PPVC in reducing carbon emissions levels. ?
