Singapore’s Building Construction Authority and partner agencies have made the CORENET X digital approval system compulsory for every new construction submission starting October 2026. The move is intended to accelerate approvals for education-related facilities and other built-environment projects.
The CORENET X platform was introduced as a multi-agency digital hub for building approvals. From October 2025, the system became mandatory for large-scale projects, and a year later the requirement expands to all new building submissions across the city-state [2][3]. The rollout is coordinated by the Building Construction Authority (BCA) together with the Urban Redevelopment Authority (URA), National Environment Agency (NEA), Land Transport Authority (LTA), and Public Utilities Board (PUB) [3][4].
The BCA, URA, NEA, LTA, and PUB are the primary government bodies overseeing the platform, while more than 320 architectural, engineering, and construction firms have already onboarded CORENET X [1][4]. The system standardizes submission data using the IFC+SG format, enabling agencies to access consistent, machine-readable information for faster review [4]. The digital hub consolidates permit applications, environmental clearances, transport impact assessments, and utility connections into a single portal, reducing the need for duplicate paperwork [3][4].
Implementation Timeline and Requirements
CORENET X was first piloted in 2023 and entered mandatory use for projects exceeding a defined cost threshold in October 2025 [2][3]. The October 2026 deadline applies to every new building project, regardless of size or sector, requiring users to submit designs, plans, and supporting documents through the digital portal [2][4]. The platform enforces the IFC+SG data structure, which combines Industry Foundation Classes (IFC) with Singapore-specific extensions to capture local building codes, fire safety, and sustainability criteria [4].
Developers and design firms must register on the CORENET X portal, undergo a brief onboarding session, and certify that their BIM models comply with the IFC+SG schema before submission [1][4]. The BCA conducts periodic audits to ensure compliance, and non-conforming submissions are returned for correction, a process designed to prevent delays later in the approval cycle [3].

Agency Collaboration and System Features
Singapore Mandates CORENET X Digital Platform for All New Building Projects
The CORENET X initiative represents a coordinated effort among five regulatory agencies. The BCA leads the overall platform governance, while the URA provides urban planning parameters, the NEA assesses environmental impact, the LTA evaluates transport implications, and the PUB reviews water and drainage requirements [3][4]. Each agency accesses the same digital submission, allowing simultaneous review and reducing the traditional sequential hand-off model [4].
Key technical features include real-time status tracking, automated compliance checks against Singapore’s Building and Construction Authority (BCA) regulations, and integrated feedback loops that alert submitters to missing information [3]. The platform also supports a secure data exchange protocol, ensuring that proprietary design information remains confidential while still being accessible to authorized agency reviewers [4].
The mandatory adoption of CORENET X is expected to shorten approval times for school construction, campus expansions, and renovation projects. Faster approvals reduce the lead time between design and ground-breaking, enabling educational institutions to commence building works earlier and align project delivery with academic calendars [2][3]. Cost savings arise from fewer resubmissions and reduced reliance on paper-based processes, which can lower overall project budgets for school boards and private developers [3].
Architects, engineers, and contractors working on education facilities must adapt to the IFC+SG BIM requirements, prompting investment in training and software upgrades [1][4]. The BCA’s July 2026 Ask-Me-Anything session provides guidance on navigating the submission portal and modeling standards, offering immediate support to firms transitioning to the new workflow [1].
Students and educators benefit indirectly as accelerated construction timelines translate into quicker access to modern, technology-enabled learning environments. The streamlined process also supports the government’s broader agenda of modernizing school infrastructure to meet future skill demands [2].
