Introduction: A New Digital Era for Building Submissions
Starting October 2025, Singapore will make it mandatory for all large-scale building projects to use CORENET X for regulatory submissions. This shift marks a significant milestone in the government’s push toward digital transformation in the built environment sector, ensuring faster, more coordinated, and future-ready construction processes.
What is CORENET X?
CORENET X is the next-generation platform developed by the Building and Construction Authority (BCA) in collaboration with multiple government agencies.
Unlike the older system, CORENET X:
- Provides one-stop submission for regulatory approvals.
- Enables multi-agency collaboration in a single environment.
- Shortens approval timelines by reducing back-and-forth queries.
- Integrates with Building Information Modelling (BIM) to streamline design-to-construction workflows.
Why the Shift is Significant
The mandatory adoption of CORENET X aims to:
- Speed up approvals for large projects.
- Enhance accuracy through digitalized submissions.
- Reduce project delays caused by fragmented communication.
- Improve compliance with building codes and sustainability standards.

For developers, consultants, and contractors, this represents a paradigm shift in how projects are planned and executed.
Who Will Be Affected?
From October 2025 onwards, all large projects — typically defined as those exceeding a certain gross floor area (GFA) or involving multiple regulatory agencies — must be submitted through CORENET X.
This includes:
- Commercial towers
- Large residential projects (GLS and private launches)
- Industrial complexes
- Institutional and infrastructure projects
Smaller projects may transition gradually, but large developments will lead the way.
Impact on the Property & Construction Market
The rollout of CORENET X will reshape the industry in several ways:
- Developers: Faster approvals mean earlier project launches, crucial for GLS and private residential sites.
- Contractors: Digital integration reduces rework, saving costs.
- Homebuyers: Potential for shorter project timelines and faster delivery of housing.
- Sustainability: CORENET X supports compliance with green building standards.
Challenges in Transition
While the benefits are clear, the transition won’t be without hurdles:
- Training: Industry players must upskill to fully utilize the platform.
- System Readiness: Firms may need to invest in software and digital infrastructure.
- Short-Term Adjustment: Initial submissions may face learning-curve delays.
The government is expected to provide support, workshops, and resources to ease the transition.
Future of Singapore’s Built Environment
CORENET X is part of Singapore’s broader Construction Industry Transformation Map, aiming to:
- Enhance productivity.
- Drive digital innovation.
- Strengthen climate resilience in construction.
By making CORENET X mandatory, Singapore positions itself as a global leader in digital construction regulation, setting standards that other nations may follow.
Conclusion: A Milestone for Digital Transformation
From October 2025, the mandatory adoption of CORENET X for large projects will fundamentally change how building submissions are managed in Singapore.
It promises faster approvals, smoother collaboration, and better compliance, aligning with the nation’s vision of a smart, sustainable, and future-ready built environment.
