The Compliance Checker for Accessibility relies on both your model’s data and its geometry to execute checks. To deliver accurate results, your BIM model must be structured in line with openBIM standards. The good news: we’ve aligned the information requirements for the checker with IFC+SG export standards. That means if your model already meets IFC+SG requirements for CORENET X, it’s also ready for code checking — no extra work needed.
Why Preparation Matters
Automated rule-checking is only as reliable as the information provided. Missing or inconsistent data can lead to false results, misinterpretations, or missed issues. By preparing your model correctly, you can:
Reuse the same IFC+SG deliverables for both submission and compliance checking
Avoid unnecessary rework and catch gaps before submission
Ensure the checker can accurately interpret your design intent
Produce better-quality models for both project coordination and regulatory workflows
What Your Model Needs to Include
For the Compliance Checker to validate accessibility requirements, your BIM model must include a few critical elements. These are not arbitrary. They are directly tied to the clauses in the Code on Accessibility 2025.
Sanitary fixtures (water closets, wash basins, showers, urinals)
The Accessibility Code specifies detailed requirements for accessible washrooms and water closet cubicles: covering minimum internal dimensions, turning radii, and fixture placement. For example, clauses in Chapter 5 (e.g. 5.2 and 5.6) require accessible individual washrooms and water closet cubicles to have adequate clearances and fixtures positioned for wheelchair manoeuvring. Without these fixture objects, the Compliance Checker cannot measure clear spaces or verify compliance.
Basic structural elements (slabs, columns, walls)
Structural elements are essential to define the boundaries of circulation areas such as corridors, lobbies, ramps, and landings. They are also essential for verifying accessible routes, which are continuous paths that wheelchair users can travel between key spaces. For example, clauses in Chapter 4 require accessible routes to maintain a minimum clear width and unobstructed passage throughout. The checker needs slabs and walls in place to measure whether those clearances exist.
Spaces (Revit Rooms or Archicad Zones exported as IFC Spaces)
Space definitions tell the checker what each part of your design is for. Different spaces trigger different rules under the Accessibility Code. For example, circulation spaces must provide accessible routes, and washrooms must meet fixture clearances. If spaces are unnamed or left blank, the checker cannot apply the correct rules. Naming spaces correctly (e.g., “accessible washroom” vs. “meeting room”) communicates your design intent and ensures the right compliance checks are applied.
IFC Export Settings (Aligned with IFC+SG Standards)
Sanitary fixtures, structural elements, and space names form the minimum dataset the checker needs to function. With these in place, automated checks become accurate, meaningful, and directly tied to the requirements of the Accessibility Code. Correct export settings ensure that your model’s information is transferred reliably into the IFC format for checking. We’ve aligned the checker’s requirements with IFC+SG, Singapore’s standard for digital submissions. This means that if your model is already prepared for IFC+SG, it’s also ready for automated rule checking — no extra work required. Proper IFC mapping preserves key data such as space boundaries, element classifications, and parameters that the Compliance Checker relies on.
Tools to Support You
Preparing your BIM model for automated checks does not have to be difficult. We are curating a set of free resources and product reviews to help you choose the right tools and workflows.
Free Use of Plannerly to Check Your Information Readiness
From now until May 2025, you can try out Plannerly for free. It is a great tool that you can use to ensure your model meets the information requirements of your project – not just for this compliance checker. Use it to automatically validate if your model meets the IFC+SG-aligned requirements for code checking.
BIM Modelling Guide – Export Settings, Naming Conventions, and More
A practical step-by-step guide to help you create models in Revit correctly and in the most fuss-free way. It is available as a PDF to download and share.
Attend a Live Training Session
Learn from our experts how to structure your model and export correctly to IFC+SG. The trainings are free to attend and will take 4 hours of your time.
IDS Templates to Use with Your Preferred Information Checker
In line with our openBIM philosophy, we provide the information requirements as IDS templates — freely available for you to use with any compatible information checker, not just Plannerly. There is no lock-in, and no single-platform dependency. You choose the tools that work best for your team.
Product Directory & Reviews
Explore independent reviews of openBIM-supporting tools like Qonic, openAEC, BIMcollab, and Plannerly. We highlight how these tools fit into an openBIM workflow and what value they bring to model quality, collaboration, and compliance.
Support During Alpha Testing
During the alpha testing phase, happening from now until Nov 2025, we will provide hands-on BIM knowledge and resources to support you to meet the information requirements at no cost. By contributing your models to us to use for the alpha testing phase of this project, you get free support and resources to review and enhance your model to meet IFC+SG standards. The AcePLP Code Checker Squad will also provide feedback on how you can improve information quality in your model, and deliver a model evaluation summary showing how your model aligns with the checker’s requirements.
Independence During Beta
From 24 November 2025, when the public beta begins, you will be able to upload models directly to the web-based checker. Through the free compliance checker workshop, you will learn to use the free Plannerly templates to check your model for information readiness. You can apply the same principle using the free IDS templates that we provide with any other checker to validate model readiness. By using the Compliance Checker for Accessibility, you will receive automated compliance reports linked to code clauses. All tools remain free to use during the beta period.
