Autodesk Navisworks Sub Contractors Involved in the Project The BIM TEAM: Typically at minimum 5 Trades Structural / Mechanical / Plumbing Electrical / Fire Protection DON’T FORGET CIVIL!
NAVISWORKS DETAILS
Outside Navisworks A. The Grid System – there is one grid system for the project. This should be provided as a supplemental CAD file to all members of the BIM team. All grid-to-grid dimensions are shown. All files must align to the project grid system. If a file is out of alignment, it is the responsibility of that team member to address and resolve the issue.

PROJECT MAINTENANCE
Models - Coordinator Task Once all the initial models have been generated and you are in the revision process, the models will be changing on a regular basis. When is an RFI necessary? This will be a question that is answered differently from project to project. In any case, the trades will have to produce RFIs as they ramp up for construction. Corrections via RFI process or internal dialog must be made in the models and new revisions provided to the coordinator. The key management issue here is keeping the whole team on the most current models.
Details of a Project A typical day for the BIM coordinator includes: maintenance of project files; relaying vital information between the general contractor and subs involved in BIM; creating and publishing clash reports for the subs; and odds and ends involving CAD technologies.

B. File setup. The use of a naming convention, makes the use of Navisworks easier A naming convention for models, by building: <TRADE>_<Project>_<BuildingName >_NAVIS_RN###.nwc
Therefore, the structural file for Building A in Project 1: STRC_Project1_A_NAVIS_RN000.nwc
