Mandatory Collection and Submission of Construction Productivity Data
Under Regulation 10(a) of the Building Control (Buildability and Productivity) Regulations 2011, builders need to install and operate Biometric Authentication Systems (BAS) to enhance the reliability and efficiency in the collection of Construction Productivity Data (CPD). Building works which are subject to this mandatory submission include those which:
- Occupy a Gross Floor Area (GFA) of 5000 m2 or more
- Have submitted for Planning Permission on or after 1 November 2014
- Are new building, upgrading and A&A projects
Builders are currently required to submit CPD monthly via the Electronic Productivity Submission System (ePSS) from Permit to Commence Work (PTCW) issuance until final Temporary Occupation Permit (TOP) or Certificate of Statutory Completion (CSC) is issued.
*NEW* Enhanced Automated Construction Productivity Data Submission
Currently, builders manually collate onsite and offsite CPD into various Excel templates before uploading to ePSS. To streamline the data submission workflow for the industry, builders will be required to submit their CPD through a BAS that is integrated with the data exchange platform (i.e. SGBuildex) for new applicable projects with PTCW applications made from 1 May 2026. Please see related circular issued on 1 Dec 2025.
Under the new workflow, builders will use a single data schema for all project types to submit monthly CPD automatically and directly to BCA via a BAS that connects to SGBuildex via API. Work trades have also been streamlined into a list of broader categories, making it easier to register workers especially those who perform multiple functions. This reduces administrative burden and enhances operational efficiency for builders.
The data exchange platform is currently open to all builders with new and ongoing projects. Offsite fabricators, including those involved in precast, structural steel, prefabricated mechanical, electrical and plumbing works, are also welcome to participate in this voluntary phase. Interested parties may register here to onboard their projects onto the new data exchange platform. BCA will contact you to follow up.
