To ensure that the different Prefabricated Prefinished Volumetric Construction (PPVC) systems being used at the mandated 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:
A more detailed explanation of the acceptance framework as illustrated in Figure 1 can be found below:
(a) Check for performance requirements – PPVC suppliers and manufacturers who intend to supply their PPVC systems to be used at the mandated development sites must first ensure that their PPVC system and the in-built bathrooms (if any) meet the PPVC performance requirements. For the performance requirements, please refer to the Code of Practice on Buildability 2017.
(b) How to apply – PPVC suppliers and manufacturers are required to submit their applications and proposals to the BIP according to the PPVC checklist and in-built bathroom checklist with the following documents:
a. Completed and duly signed application form
b. Documentary evidence of compliance with codes of practice (Singapore or overseas)
c. Track record of implementation overseas
d. Material or product specifications
e. Quality certifications or test reports by accredited laboratories
f. Any other relevant information
(c) Evaluation by BIP – There are two separate evaluation stages.
Stage 1: Consists of a PPVC Screening Panel chaired by BCA and other industry representatives, who will evaluate the design and materials used.
Stage 2: Once the PPVC system is accepted by the PPVC Screening Panel, the BIP Secretariat will then assist and coordinate submissions to the remaining regulatory agencies under the BIP and facilitate early resolution of outstanding issues between the applicant and the respective agencies.
(d) In Principle Acceptance – If accepted, relevant letters of In Principle Acceptance (IPA) will be issued to the PPVC supplier/manufacturer.
(e) Listing on BCA’s website – View list of accepted PPVC suppliers/manufacturers.
2. Accreditation by PPVC Manufacturer Accreditation Scheme (MAS)
In addition, the production facilities producing PPVC systems must be accredited under:
