Building Information Modelling (BIM), Integrated Project Delivery (IPD), Level of Detail (LOD), Model Progression Specification (MPS) are discussed in this article on AECbytes about Organizing the Development of a Building Information Model.
Representations of building elements in a BIM, though, are exact, whether they’re intended to be or not, and can give a false indication of the precision actually known at a given point in the design process. … The need for a framework for defining a BIM’s precision and suitability for specific uses becomes obvious.
AIACC IPD Task Force Technology Subcommittee has developed the broad-based consensus around this process:
Paul Audsley, NBBJ Architects
Jim Awe, Autodesk
Jim Bedrick, Webcor Builders (chair)
Dan Gonzales, Swinerton Builders
Mario Guttman, HOK Architects
Atul Khanzode, DPR Construction
Greg Luth, GPLA Engineers
Tony Rinella, Anshen + Allen Architects
John Wynne, Lucasfilm (owner)
