Walter,
I'm not sure about the requirements for multi-prime public projects that you refer to but we use a two phase work agreement with our projects. Phase I is the creation of Revit model including architecture, structural, MEP, interiors and FF&E. The model is complete to show design intent, scope and quality. We work with a CM to maintain budget through the model creation process. The model is then bid or assigned to sub-contractor and suppliers. Following the selection of sub-contractor we enter in Phase II services. In this phase we and our consultants work with the CM, sub-contractors and suppliers using a Virtual/Design/Construct (VDC) big room process to complete documentation to the point of fabrication data. Through this process materials can be acquired and prefabricated when appropriate to the process and the need for many shop drawings can be eliminated.
We split the fee arrangement with Phase I being a negotiated lump sum and Phase II as an hourly fee.

We receive AutoCAD files from our vendors and suppliers for nearly all of our work. We print a cover page with transmittal information. We also print the AutoCAD drawings to PDF's. We Use Blue Beam to mark corrections and notes, and then the shop drawings, or approval files as we call them get returned. We use PDF packages as the file fromat for the PDFs, so that we can transmit a single file that encapsulates multiple multi-page PDF files. We are planning to move to Revit by next year. I'm not sure how the process in Revit would be much different. We would be interested in any other thoughts that were out there.

Does anyone have case studies or know of resources to use as a guide for the proper procedures and the liability issues of using BIM for shop drawings on multi-prime public projects?
Meanng the architects/engineers models used much as 2D CAD drawings would be. It's obvious there are issues, but anything documented? Also how to get from LOD 300 (architect/engineer) to 400 (contractors/fabricators) ?
