Resolutions from Product Room, Process Room, International User Group, International Technical Committee, and Jointed resolutions.

Product Room

Product Room 1: The local content developments are valuable, but we agree that international harmonisation of product/system properties is necessary for interoperability.

Product Room 2: Some Software developers have already implemented proprietary systems partially addressing users needs, but we know that openBIM is the solution which they will acknowledge ultimately.

Product Room 3: Establish a small pilot project to add, review & assess a product or system attributes in bsDD from at least 3 countries for end of 29 Nov - 1 Dec, London UK bSDD meeting, based on an acoustic ceiling: US, FR (to be confirmed), UK, SE (to be confirmed), NO, JP (to be confirmed), AU (to be confirmed) and CA (to be confirmed).

Product Room 4: Based on the outcomes of Nov meeting, identify potential improvements for the content creation process and develop a business case for the use of bsDD (based on Harvard Business Review template - Deke Smith to provide), by 30 December 2012.

Product Room 5: Before the next Product Room meeting, undertake web workshops on the business case (from Resolution 3 above).


Process Room

Process Room #1: buildingSMART should offer accreditation of third-party data validation services based on buildingSMART-recognized IDM and MVD enabled by the use of mvdXML.

Process Room #2: Extensions to the IFC schema shall be based on IDMs recognized by buildingSMART.

Process Room #3: Software certification performed by or accredited by buildingSMART shall be based on IDM and MVD recognized by buildingSMART.

Process Room #4: In order to be recognized as an official buildingSMART IDM, there must be a guarantee that the IDM will be supported by software products and used in the industry.

Process Room #5: Asset Management (AU, UK & NO) and Building Programming (NO, CA and DK) are considered as high prioritized BIM Use Cases, and a business case be developed by 30 Dec 2012. US & CA will review proposals.

Process Room #6: Development of International BIM Guidelines, as a precursor to an international standard, should be reinitiated. US will lead, with UK, Nordic, & CA.

Process Room #7: There is a need for procedures and methods to manage and use of BIM and open standards in different contractual arrangements. Prepare presentations on openBIM and contractual/procurement procedures for the next meeting.

Process Room #8: There is a need for educational material in order to train the industry in BIM and open standard based environment. Prepare presentations on this topic for the next meeting.

Process Room #9: Correct use of IFC properties by authoring/IFC-exporting tools, when available, is a crucial for efficient use of openBIM. IUG requires ITM to make use of IFC properties, when available, a condition for software certification.

Process Room #10: IUG requires ITM to specify standardized rules for documenting and communicating area/quantity data with openBIM.

Process Room #11: IUG requires ITM to specify standardized down-stream/up-stream rules for change management of model data between software in order to preserve consistency and avoid manual work with model up-dates.

Process Room #12: IUG endorse users of openBIM to require prioritized implementation of IFC4 from their ISG and vendors.

Process Room #13: IUG requests Jan Karlshoej with NO to participate in the development of a rollout strategy for IFC4 from an end-user perspective for the next IUG meeting.

Process Room #14: This meeting has identified the strong common interest in Infrastructure, GIS & BIM and industrial plant and requests Excom to develop a plan for its implementation. IUG appoints Vaino Tarandi as buildingSMART’s representative to TC211 Task Force for BIM/GIS. IUG recognises the excellent initiative on GIS/BIM and looks forward to collaboration on this project.



IUG Resolution 1: IUG elects Kjell Ivar Bakkmoen as chairman until the next elections in March 2013.

IUG Resolution 2: IUG extends appreciation to Jøns Sjoegren for leading the work to date.

IUG Resolution 3: IUG extends appreciation to Japan Chapter for excellent hosting of this meeting, and notes the outstanding Meeting Guidebook.



4-1 ITM encourages the various chapters to complete the PSet translations as much as possible by the end of November to become part of the final IFC4 specification.

This should be done using the current method (Excel spreadsheets) until a multi-user tool becomes available. The Technical Coordinators should act as gatekeepers to PSets and work with local user groups.

4-2  A Tool to access and update bsDD content has to be developed urgently. Funding and resources need to be made available. ITM requests EXCOM to request Catenda and/or others for a proposal to perform this work. The tool should be designed to support properties and templates also for the Product room requirements.

4-3  The taskforce that has been working on management of PSet translations should deliver the results by end of November.

6  ITM defers the proposed resolution to adopt BCF schema for clarification by TECHCOM.

7-1 ITM authorized Thomas to explore the possibilities of having addendums or new editions of ISO16739 as IFC4 progresses with Howard Maison from ISO TC184/SC4.

7-2 ITM thanks MSG and Thomas Liebich for successfully completing IFC4 and related standards and manouvering through the ISO standardization process.

7-3 All chapters should take steps to get ISO IFC4 adopted as regional/national standard.

7-4  ifcXML for the entire IFC4 schema is called “simple ifcXML4”

7-5  ITM requests MSG to develop a high level feasibility study to move to UML/XSD development environment by end of November and how does it affect the IFC for infrastructure scoping work. We should retain Part 21 support for backward compatibility.

10  ITM resolved to focus on large scale deployment of openBIM in the 2016 Technical Roadmap. The Road map will support national and international efforts and initially coalesce around the UK BIM initiative.

11  ITM expressed sincere thanks to Dr. V. Bazjanac and all TAG members and contributors for the excellent work done on the draft 2016 Roadmap and the following 2020 Roadmap.

12  ITM has accepted the progress report on bSi 2016 technical roadmap and has instructed TAG to continue the work and deliver a high level intermediary plan for the work that needs to be done on HM Government’s BIM initiative project by 2012-11-09. In addition ITM is requesting that the UK contingent discusses the issue of funding the completion of the plan.

13 ITM is committed to offer serious participation and review of the above plan as requested by TAG.

13  ITM acknowledges the FP 7 project “DuraArk” for the Digital longterm Preservation of Building Data starting in Feb 2013. ITM endorses the efforts aiming at the integration of point cloud data into the IFC Model as well as the development of a governance framework for semantic concepts based on ISO 12006-3.

14  ITM/IUG asks Jan Karlshoej to coordinate information meetings on IDM part 2 and coordinate feedback from pilot projects.

18-1  ITM recognizes the need to update bSI website with a clear statement that the Built environment and Infrastructure are part of the BSI scope.

18-2  ITM recognizes the need for substantial developments to reach buildingSMART standards for INFRA; also it recognizes the need for substantial funding. ITM encourages the OpenINFRA steering committee to enter in discussions with potential investors and to align different agendas in a program plan. A first meeting will be scheduled in November/December 2012.

18-3  ITM/IUG accept the new project "OpenINFRA: buildingSMART MVD for LandXML v1.2" as proposed by the Nordic chapter and encourages all chapters to participate in development of this model view definition and to support its implementation and use.

18-4  ITM/IUG accept the new project "OpenINFRA: IFCBridge+" as proposed by the French chapter and encourages all chapters to participate in development of this model view definition and to support its implementation and use.

19  ITM/IUG will consider Germany’s invitation to meet there in fall 2013



ITM/IUG Joint 1: ITM/IUG acknowledges and appreciates the extensive work of convener Henk Schaap and other buildingSMART members for their work with the ISO 29481-2 IDM Part 2.

Before ITM/IUG formally recognize IDM part 2 as a buildingSMART standard that could contribute to interoperability in the building process,

  • it should be clear how future development can be financed
  • a technical review of the standard should be performed by ITM
  • a software implementation review should be performed by ISG although it should be taken into account by the standard is already implemented in software products.
  • IUG should evaluate the value of the standard from a user point of view All reviews and evaluations have to be completed by February 2013. A formal decision to recognize ISO 29481-2 IDM Part 2 will be based on the reviews and evaluations.

ITM/IUG encourage User groups to execute pilot projects and give feedback and comments
