Prefabricated Bathroom Unit (PBU) Acceptance Framework

PBU designs have evolved over the years and may also involve the use of alternative materials in its fabrication. To ensure that the different PBU 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.

A more detailed explanation of the acceptance framework as illustrated in Figure 1 can be found below:

(a) Check for performance requirements – PBU suppliers and manufacturers who intend to supply their PBU systems to development sites must first ensure that their PBU system meets the PBU performance requirements. For the performance requirements, please refer to the Code of Practice on Buildability 2017.

(b) Submit application to BIP– Applicants should submit the completed application form and supporting documents to the PBU Screening Panel under BIP.

(c) Evaluation by BIP – There are two separate evaluation stages. 
Stage 1: Consists of a PBU Screening Panel chaired by BCA and other industry representatives, who will evaluate the design and materials used. 
Stage 2: Once the PBU system is accepted by the PBU 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 PBU supplier/manufacturer.
