New Guide Helps MEP Contractors Navigate BIM

MCAA BIM guideThe Mechanical Contractors Association of America (MCAA) has launched a new guide to help MEP contractors understand how to incorporate and leverage leading edge technologies and processes into their projects’ spatial coordination efforts. Titled Achieving MEP Spatial Coordination Through BIM – A Guide for Specialty Contractors, the document was developed by a task force comprised of members from MCAA, the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) and the National Electrical Contractors Association (NECA), with financial underwriting from the Mechanical Contracting Education & Research Foundation (MCERF).

How LOD 350 Benefits BIM for Building Construction

BimForum 2013 LOD Spec

The BIMForum recently released the 2013 Level of Development (LOD) Specification, which includes a new LOD level – LOD 350. Prior to this development, the AIA G202 LOD definitions left a lot of room for interpretation by designers and engineers, thus creating uncertainty about model integrity by downstream users. General contractors often recreate models from scratch because they can’t rely on the quality of models coming from other project team members. The new 2013 Level of Development Specification changes all this. Continue reading…

Using Point Clouds in Clash Detection

We use Autodesk Navisworks almost exclusively as our primary clash detection tool. However, up until about a year ago, we have only worked with “projected” models – that is, shop drawings in 3D format that convey what the project will look like once that particular system is installed. Combining all of these files into Navisworks usually results in what’s known as “clashes,” or conflicts between systems where certain elements are competing for the same space. Continue reading…
