BIM Collaboration Format explained

buildingSMART has published a short video explaining BIM Collaboration Format, BCF

It gives a 2 minute overview of one aspect of buildingSMART’s vendor neutral approach to design, construction and operate of assets in the built environment.

We are grateful to the members of the BCF Group and the support of Aconex for producing this video.

Rijkswaterstaat, a leading infrastructure owner becomes a member of buildingSMART

RWS-150x52The Dutch roads and water systems authority, Rijkswaterstaat has joined buildingSMART International as a standard member, one of the four classes of membership offered by bSI. Rijkswaterstaat is a strong supporter of open BIM and is already contributing funding to some of buildingSMART’s infrastructure projects.

‘In the Netherlands we have a significant infrastructure network of roads, viaducts, bridges and tunnel complexes, together with our extensive network of waterways and water systems,’ said Herman Winkels [ Program Manager of Rijkswaterstaats Bim programme]. ‘We need optimal data-sharing solutions based on open standards for design, construction and maintenance. International cooperation is in our vision essential to achieve this, since the market (IT wise and construction wise) is really an international one. Hence Rijkswaterstaat invests in bSI to share this vision and create the relevant open standards.’

Rob Roef, the Vice Chair of buildingSMART Benelux, said ‘we are pleased that Rijkswaterstaat has joined the international membership team as their experience and abilities will give real drive to the development of the new international infrastructure standards being developed. This in turn will then have significant benefit for the use of open BIM in the Netherlands as well as the rest of the world.’

Welcoming Rijkswaterstaat to bSI, CEO Richard Petrie commented, ‘Having such a significant infrastructure owner closely involved with our work will enable faster uptake of digitisation in infrastructure.’

The BCF 2.0 proposal is public on github

The BCF 2.0 proposal is public on github: Please use the issue tracker for feedback. Click on the image for the link.

buildingSMART-ISG (Implementer Support Group) has created a task group for defining BCF 2.0 and the result of this work will be provided before the next ISG meeting in Prague, on the 9 of September 2013. There are lots of improvements proposed, most important are:

  • Support for multiple snapshots/viewpoints on topics.
  • Improved control of colour, visibility and colour was added to visualization. This is a difficult issue as you never know how many models that might be open at the same time. The topic might have been created while two models where opened and is later “covered” by a third domain model.
  • New support for bitmaps on viewpoints. This is to allow for overlays of text, sketches etc in viewpoints.
  • Support for “BimSnipplets”. These are in effect small ifcXML, ifc2x4 or ifc4 files. This is to support eg. provision for voids.
  • Support for “DocumentReference”. Could refer to a file in the topic folder or to an URL.
  • Email added to comments for better identification of authors.
  • A topic comment can now have the status of open or closed. If more granularity is needed “VerbalStatus” can be used. A set of proposed status lists might be provided with the documentation of the format.
  • minor optional improvements like the possibility to index topics was also added.

The improved BCF 2.0 will be backwards compatible with BCF 1.0. The work is being documented on ISG Jira with participants from Catenda, DDS, Iabi, ISG, Solibri and Tekla.

A second task group currently is working on a standardised webservice, so that BCF could be synchronised automatically among various applications and platforms, in future.

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.

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.

Background
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
