Prefabricated Prefinished Volumetric Construction (PPVC)
"Prefabricated Prefinished Volumetric Construction (PPVC)" means a construction method whereby free-standing volumetric modules (complete with finishes for walls, floors and ceilings) are:
in an accredited fabrication facility, in accordance with any accredited fabrication method, and then installed in a building under building works
Benefits of Using PPVC
To raise construction productivity and fundamentally change the design and construction processes, BCA encourage the industry to embrace the concept of Design for Manufacturing and Assembly (DfMA), where construction is designed such that as much work may be done off-site in a controlled manufacturing environment as possible.
PPVC is one of the game changing technologies that support the DfMA concept to significantly speed up construction. It can potentially achieve a productivity improvement of up to 50% in terms of manpower and time savings, depending on the complexity of the projects. Furthermore, dust and noise pollution can be minimised as more activities are done off-site. With the bulk of the installation activities and manpower moved off-site to a factory controlled environment, site safety will also improve.
Required Use of PPVC
The use of Prefabricated Prefinished Volumetric Construction (PPVC) is required for selected non-landed residential Government Land Sale (GLS) sites from 1 Nov 2014 onwards. Further details on the requirements are stipulated in the Code of Practice on Buildability 2017. You may find out more information about this requirement through the following circular issued on 30 Nov 2015
PPVC Acceptance Framework
To ensure that the different PPVC systems being used at development sites are reliable and durable, BCA has set up an acceptance framework consisting of building regulatory agencies as well as industry experts to ensure that the design and materials used are robust and can meet the minimum standards set.
The PPVC acceptance framework consists of two parts:
