Adoption IfcXML in upcoming version IFC4 from buildingSMART, promising.
Presentation Summary Phase1 by Thomas Liebich, Matthias Weise – buildingSMART
Revised version v1.1 Dutch BIM standard. of 1 February 2013.
Version 1.1 of the standard is the result of advice and practical findings. To apply the standard to clarify and facilitate a number of technical and substantive changes made. In some cases, a different technical solution has been adopted in order to achieve a similar result. In addition, a number of additional requirements have been removed and editorial corrections made.
Overview of the main changes:
The full norm (Dutch)
Christopher Zoog of HOK presented this great explanation to the New York City Revit User Group.
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:
Various IFC exporting tools, as well as IFC specific editing tools will also be discussed and demonstrated.
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.
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.
