ID Credit Title: BUILDING INFORMATION MODELING (BIM) Credit Intent: Implement an integrated 3D model to optimize material usage and reduce overall construction waste. The general contractor and subcontractors will be able to plan for more prefabrication rather then onsite fabrication since the 3D model will provide accurate quantities, measurements and final location of material in the building since the project has already been built once digitally. The prefabrication of materials in return will reduce the amount of material used due to fabricating it correct the first time and the amount of waste that is generate onsite. Benefits to the project - reduced rework from conflicting trades, reduction of unused or extra material, and opportunity to make corrections before an element is buried by other trades. Requirements for Compliance: Implementation of a BIM plan that identifies trades, site logistics and owner furnished elements where 3D planning and coordination will be used. Staff must be in place that can facilitate the extension of the typical 2D detailing and coordination into a 3D model based coordination and planning process. The staff must be able to help integrate individual trade models into a single consolidated model for review on a weekly basis. Systematic evaluation of each consolidated model will be used to identify and resolve conflicts. A final consolidated model must be agreed to by all parties prior to material release and pre-fabrication. - Model Mechanical, Electrical, Plumbing, Sprinkler, Stairs, Exterior Skin, Site and Interior Partitions in 3D - Consolidate individual models into a single model on an iterative basis - Test all elements for conflicts, collisions, and access - Translate 3D model information into field layout coordinates - Verify installations against the 3D model as trades complete work Submittal: Confirm trades are fabricating, planning and installing based on the agreed properties in the coordination 3D model. Include list of participants in 3D modeling. Submit list of items that will be pre-fabricated for the project.
