The dates
- 1 October 2025: CORENET X mandatory for new projects of 30,000 m² GFA and above.
- 1 October 2026: mandatory for new projects of 5,000 m² GFA and above (joint URA and BCA circular, July 2026).
- Smaller projects may opt in and can continue on CORENET 2 for now. Projects of 5,000 m² and above that began CORENET 2 submissions by 30 September 2026 may continue there.
CORENET X is Singapore's coordinated regulatory submission platform for building works. It replaces the old approach, in which each agency received and processed its own submissions, with a joint process organised around project gateways. Agencies including BCA, URA, SCDF, PUB, NEA, LTA and NParks review the submission together at each gateway.
Why it matters to M&E
- Earlier coordination. Agencies review together, so mechanical, fire and sanitary decisions must be settled at the same time as the architecture. Late M&E changes cost more.
- Model-based submissions. Submissions are built around BIM models carrying the information the agencies need, using Singapore's IFC-SG data standard. M&E consultants need to model with that data in mind.
- One coordinated response. Fewer contradictory comments from different agencies, but a weak discipline holds up the whole gateway.
What owners should do
- Check your project's GFA against the 5,000 m² threshold and your submission start date against 30 September 2026.
- Appoint M&E consultants and PEs early enough to meet the gateway programme.
- Ask each consultant how they will deliver IFC-SG-compliant information.
- Smaller projects: consider opting in voluntarily if your team is ready. The platform will eventually cover everyone.
Implementation details are still evolving. Always check the latest URA and BCA circulars before you finalise a submission strategy.
