Singapore BCA Compliance with VitruAI

BCA scope covered in the VitruAI rule library

VitruAI treats Singapore BCA compliance as a structured rule library that spans statutory requirements and Codes of Practice, then maps them to model checks and IFC export validation. The same rule-authoring approach used in the Code Compliance Agent and Dubai Villa Code work carries across, but the clauses and thresholds follow BCA’s Building Control framework and CORENET X guidance.

Building Control Act + Building Control Regulations. These set the statutory baseline for building works in Singapore, including structural safety, fire compartmentation, and means of escape. In a Labs engagement, VitruAI encodes project-relevant clauses into checks that read Revit, ArchiCAD, or IFC models and highlight non-compliant elements before the Qualified Person prepares a formal submission.

Code of Practice for Accessibility in the Built Environment. The rule pack focuses on approach routes, entrances, internal circulation, and sanitary accommodation. Typical checks include corridor and ramp widths, door clear openings, turning circles, grab bar placement, and accessible sanitary compartment layouts, all tied to explicit clause references so the project architect can see which BCA requirement each flagged element relates to.

Buildable Design Appraisal System (BDAS). For BDAS, VitruAI reads structural and architectural layouts to compute indicative buildability scores based on wall, slab, and column regularity, prefabrication potential, and standardisation. The Labs engagement aligns the scoring method with the current BDAS handbook so that early design options show how close they sit to the minimum required score before submission to BCA.

Universal Design Mark. Universal Design Mark remains a voluntary framework above the mandatory Accessibility Code. VitruAI flags opportunities where the design already meets or is close to meeting UD Mark criteria, such as additional wayfinding support or enhanced accessibility features, so teams can coordinate with clients on whether to pursue certification without re-building the model late in the programme.

Green Mark scheme. The rule library cross-references Green Mark where BCA clauses interact with sustainability outcomes, for example facade performance, envelope thermal properties, or daylight access. VitruAI computes envelope and material indicators and prepares structured outputs that an accredited Green Mark Professional can use, but it does not replace the accredited assessor’s judgement or formal Green Mark assessment.

CORENET X submission profile. Singapore is an IFC-led submission jurisdiction, and CORENET X expects specific IFC entity types, classifications, and property sets. VitruAI validates IFC exports against BCA’s expected profile, highlighting missing property sets, incorrect IFC types, or misaligned classification codes before the team uploads to CORENET X or runs the Singapore BCA CORENET submission workflow.

Known limitations and Qualified Person role

Green Mark assessment still requires accredited assessor sign-off; VitruAI only computes envelope and material indicators, such as U-values, glazing ratios, and indicative energy metrics, and packages them for review. Heritage and conservation overlays are flagged for human review because conservation requirements often depend on site-specific directives and URA or BCA correspondence that sit outside the model.

Qualified Person endorsement remains required for CORENET X submission, and VitruAI’s outputs are designed to support, not replace, that responsibility. The Labs engagement configures rule packs and IFC validation routines per firm and project type, and firms that already use open workflows via IFC and openBIM integration can align their export templates so that VitruAI checks match the same IFC authoring settings used for other jurisdictions such as the Australia NCC framework.
