Utilizing BCF and IFC for Automated Dimensional Compliance Control

The authors have developed a novel methodology for utilising open standards for the reporting and correction of IFC-formatted BIMs during comprehensive dimensional control compliance. As designed BIMs rarely match exactly what was built on-site, and traditional methods for ensuring the design matches the built environment are tedious, costly, and time-consuming as stakeholders must manually navigate through the model to find problems, relying on subjective judgement. An efficient method to develop accurate as-built/as-is BIMs is by comparing point cloud reality capture data against the as-designed BIM to reflect the real-world state. The authors' novel methodology performs an automated comparison between as-built and as-designed representations, and employs the open standard BIM Collaboration Format (BCF) in the communication and correction of issues to resolve to match the true state of the built environment. Our methodology produces BCF reports containing recognised deviations between the as-is state and as-designed BIM, supported by the major BIM authoring tools.
