What is Model Checker?
Components of Model Checker
The MC comprises three distinct categories of checks.
IFC Schema Check
Quality Check
Regulatory Compliance Check
The IFC Schema Check serves as the first line of validation, identifying BIM models that do not meet basic Industry Foundation Classes (IFC) standards. Adherence to these standards ensures BIM models can be properly viewed and processed in subsequent stages by the Model Checker or by the Agencies.
Quality Check ensures the QPs have coordinated across disciplines and has inputted the necessary information in the BIM models for Agencies to conduct the regulatory review, by evaluating the completeness of model information against the CX COP requirements.
The Regulatory Compliance Check automatically assesses the BIM models for compliance against selected regulatory requirements when the necessary information is present in the BIM models.
These checks have been developed based on learning points from projects, established IFC standards, and good modelling practices from the CORENET X Community of Practice (COPr). We shared these learning points through various platforms, including seminars and the CX website. To further support QPs in ensuring BIM model quality – a common challenge in BIM model preparation – MC helps QPs to verify the BIM models against basic modelling standards. QPs should use MC to validate the BIM model during design and before submission to ensure compliance with COP and reduce iterations with the Agencies.
What do the various components mean for me?
IFC schema check: This fundamental check informs QPs upfront about BIM models which do not meet basic IFC standards and would therefore prevent further processing of the BIM models. Common issues include:
Outdated IFC schema versions
Corrupted files
When the check returns results with issues, QPs should revise the BIM models to address the issues and upload the BIM models again.
Quality Check: This check ensures BIM models across all disciplines meet the minimum quality standards specified in the CORENET X Code of Practice for effective regulatory review. It identifies issues such as:
Missing mandatory properties
Improper geo-location alignment across different discipline models
When the check returns results with issues, QPs should verify the consistency and completeness of information across all discipline models before submission to facilitate efficient agency review.
Regulatory Compliance Check: This check identifies non-compliances of BIM models against agencies' regulatory requirements. Examples of common issues include:
Insufficient headroom clearance
Undersized bicycle parking lots
When the check returns results with issues, QPs should review and confirm regulatory compliance of their design before submission.
When and where do I get to try Model Checker?
MC will be introduced to the industry in phases, starting with the MC Minimum Viable Product (MVP). This early version of MC contains selected clauses (“rules”) from different agencies’ codebooks. It will be expanded and released to the industry progressively to include more rule checks.
MC MVP will be available on CORENET X Submission Portal to allow QPs to perform pre-submission check. This will help the project team to identify issues with BIM models and non-compliances prior to actual submission.
Stay tuned for more details on MC MVP and its release date.
