IFC, what it is, and why you should care | recorded presentation Christopher Zoog

Christopher Zoog of HOK presented this great explanation to the New York City Revit User Group.

IFC - What it is and why you should care

HOK are certainly pushing and pursuing IFC in a number of impressive ways into their workflows, including pressure on software providers.

IFC, what it is, and why you should care:

IFC is often talked about being simply the “DXF format” of BIM, and while it’s true that is an exchange format for design authoring, IFC’s further usefulness is generally not well understood in the AEC industry (at least not in the US). IFC is arguably the best way to leverage data that is typically trapped inside your building information model, often by the very tool used to create it. This lecture will explore IFC’s origin, its current status, as well as how it can unlock that trapped data! Several BIM use workflows will be demonstrated including:

  • Design Authoring / Computational Design (Grasshopper to Revit, Tekla)
  • Program Validation / FM handover (dRofus, TIDA, Revit)
  • Performance based design / Simulation (MassMotion, Simergy, Revit)
  • Model based coordination / Automated Code Compliance (Solibri, Revit, BIM Collaboration Format)
  • Design Collaboration (dRofus, Revit, Model Server, BCF)

Various IFC exporting tools, as well as IFC specific editing tools will also be discussed and demonstrated.

Model-Based Code Review | utilization of BIM in the facility industry

The proof of concept phase of this project, known as AutoCodes, was completed with code authorities from 13 jurisdictions in the United States reviewing identical sets of 2D building plans.

Model-Based Code Review

The first manual review pass took several hours on average and yielded an astonishing discrepancy in results. The second pass utilized an open standard (IFC) BIM file passed through model checking software. In addition to only taking a few minutes to run, the results were perfectly consistent in all jurisdictions. Even if there are discrepancies in the model – such as spaces being classified incorrectly – such discrepancies are immediately brought to the attention of the code reviewer and become part of the audit trail during the review.
