New terms on the Open BIM market

HVACie is an information exchange specification for the life-cycle capture and delivery of information needed to describe Heating, Cooling, Ventilating (and Refrigeration) systems. SPARKie will do the same for Electrical Systems.

As an active project in the Common Building Information Model Files (COBie) from the bSA, interesting to see and to follow.

IFC4 Release Candidate published

The IFC4 Release Candidate 4 has been published on 03.09.2012. The Release Candidate 4 is the last update before releasing the IFC4 final. It is again provided for extensive public review and comments.

The IFC4 Release Candidate 4 is available now.

The main achievements of IFC4 RC4 are:

  • integrates ifcXML newly developed following the simple ifcXML technology,
  • integrates mvdXML by containing fundamental concepts and use definitions,
  • links all property definitions to the web-based buildingSMART data dictionary,
  • many new examples and other documentation improvements.

>>read and download the IFC4 RC4 specification<<

The buildingSMART community is strongly encouraged to review the current release candidate and to provide feedback using the MSG issue resolution database. The deadline for comments is 31.10.2012.

The IFC4 release combines a number of feature increases with some major rework and improvements of the existing IFC specification. It has been developed as the basis for future IFC enabled interoperability of Building Information Models. It is submitted to the International Standardization Organization (ISO) for approval as a full International Standard ISO16739.

Why Open BIM?

Why Open BIM? It is a simple question 😉

Open BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows. Open BIM is an initiative of buildingSMART and several leading software vendors using the open buildingSMART Data Model.

Why is it important?
Open BIM supports a transparent, open workflow, allowing project members to participate regardless of the software tools they use.

Open BIM creates a common language for widely referenced processes, allowing industry and government to procure projects with transparent commercial engagement, comparable service evaluation and assured data quality.

Open BIM provides enduring project data for use throughout the asset life–cycle, avoiding multiple input of the same data and consequential errors.

Small and large (platform) software vendors can participate and compete on system independent, ‘best of breed’ solutions.

Open BIM energizes the online product supply side with more exact user demand searches and delivers the product data directly into the BIM.

read the IFC Dev Blog | mvdXML 1.0 released

buildingSMART has released the version 1.0 of mvdXML – the new schema and method to publish official subsets of IFC to satisfy well defined data exchange requirements.

Model View Definitions (MSG) have been the method to publish the IFC implementation requirements to satisfy data exchange requirements since a long time. The most well known buildingSMART MVD is the IFC2x3 Coordination View 2.0, currently open for certification. Read more on the IFC Dev Blog here

The design brief for Build London Live 2012 is now available! | Open BIM event

Build London Live staff is excited to have now released the design brief for Build London Live 2012 by our design partners Studio Klaschka and organisers AEC3. This year’s brief is to build the museum for 2012 in East London. We think it is a great brief and are very excited for our teams next Monday. For everyone wishing to view the designs live, simply register here and we will send you details to log into the online workspaces.  View the full design brief for Build London Live 2012 here.

Build London Live 2012 | an Open BIM event

Announcing Build London Live, 2012 Edition – May 21st through 23rd

48 hours to make design work for the London

Building on the global success of Build London Live design events in 2008 and 2009, Asite and AEC3, in conjunction with BuildingSMART are happy to announce Build London Live, 2012 Edition.

Event Dates

This is a 48 hour virtual design collaboration starting on Monday, May 21st 2012 – Noon BST and running through to a finish on Wednesday, May 23rd 2012 – Noon BST. The concluding press conference, also delivered online via webinar, will be hosted at the Royal Institute of British Architects (RIBA) hedquarters in London.

What is a BUILD LIVE Event?

New technology is revolutionising the way buildings are designed and how the public can be engaged in the process. Via the power of cloud-based collaborative working and international developments in interoperability, Build London Live shows the power of these new paradigms for architecture, engineering, planning and construction. Through cloud-based collaboration the event is open to world wide participation.

The Challenge

On May 21st – Noon BST, a specially chosen and internationally recognisable site in London will be announced, along with a brief for a significant multi-use development. All the key information will be published in interoperable formats. Teams will be free to exploit any interoperable technology and to add updates to a public collaboration-site. All visitors will be free to comment.

The launch will coincide with the start of the buildingSMART International executive sessions in London.  A short live presentation will be made after the initial keynote speech, to brief the delegates. Teams will be asked to develop an outline proposal by midday on the Tuesday.  The event will conclude at midday on Wednesday and will be followed shortly afterwards will presentations to the press and a final jury will make a number of awards with the BuildingSMART International executive as .


Teams from around the world are invited to register in advance. The timetable is designed to allow people to contribute within their normal working hours or outside, register here:

@openBIM FAQ 14 of 14 | Open BIM

What are the benefits of Open BIM for building projects in the AEC industry?

Building projects themselves are products with their own market. With diminishing differences in building materials and technology, next to buildings’ genuine design added labels such as “sustainability” can greatly increase the potential project value on the market. The Open BIM movement offers projects an additional label with very positive associations. Future owners, operators and tenants of such buildings will have better chances to further utilize the digital building model if it was created using the Open BIM approach in the first place. This promise is worth more and more real $$$ with the continuously elongate building cycles.

Where can I find more information about Open BIM?

OPEN BIM is supported by various organizations that host related information in their own domains. To find some relevant information you may also choose to visit any of the following pages:
