AGC’s Winter 2011 BIMForum, Part 1

This article is the first of a two-part series that provides an overview of the AGC (Associated General Contractors of America) BIMForum organization and captures the highlights of its recent event in San Diego. It was focused on the theme, “BIM and Building Enclosures,” given that the building envelope is one of the most litigious and expensive aspects of building construction. The conference had presentations from AEC project teams showing how they used BIM to address the challenges of designing, fabricating, constructing, and managing the building envelope. There were also updates from some technology vendors, including a look at Tekla’s new free model collaboration tool, Tekla BIMsight.

  1. I must say that reading the latest article was somewhat disappointing, mainly because much of this seems old hat as it were. I can reference a number of projects going back as far as 2002 where contractors like Bovis LendLease in the UK were working in the ways described, so I am not sure this is as cutting edge as it seems. The big question has to revolve around how mainstream this is becoming and whether the cladding sub-contractors are getting involved (steel fabricators have been doing this for a while with Tekla), as that is where most of the risk and coordination issues sit. In addition, I know that the likes of DPR are still having to deal with the issues around Revit models being a 3D overlay with 2D base which means that take-offs can’t be done purely from the model(we have a similar situation on a hospital project we are on). I know we want to promote BIM as the way of the future but until the industry (including the software vendors) deal with these kind of issues (file size, interoperability), we are only really playing with the technology and how it could be used.

  2. Chris, I agree with your comments, particularly where you mentioned projects of this nature already being a work process as far back as 2002; in fact I was working with Jacobs Engineering on similar work methods in 2000.

    I am not sure why the industry is so fixated on Revit, the AutoCAD genre of products along with 3rd party products like CadDuct have superior interoperability and still manage good BIM implementation. AutoCAD Architecture, for example, is BIM compatible and also has IFC import/export capabilities since version 2000.
    Bring together products like AutoCAD Civil3d, CadDuct, Tekla (IFC), AutoCAD Architecture, Navisworks, and Plant3D, and you have a very powerful suite of products (all BIM compliant) that do not have the same issues of interoperability and work well together.

    The industry is spending 10s of 1000s of dollars flogging the Revit solution when there is already a viable and, in my opinion, a very good alternative.
