Project BIM Execution Plan (BExP)

Tag Process Not everything is solved with clash detection. Complete reliance on that tool underutilizes the power of the coordination software and may cause rework in the field. To minimize this, the McCarthy VDC Manager and/or Project Engineer will perform visual Constructability Reviews of the federated coordination model each week to identify items “beyond the clash”. These are items related to things like, fire rating issues with multiple penetrations, pipes out of walls, code issues, access issues for installation and maintenance, or potential clashes for content that has not been bought out or is not in the model. Every Trade Contractor is responsible for reviewing his/her folders prior to the scheduled coordination meetings. If an item cannot be resolved at the coordination meeting then that issue needs to be drafted onto the Design Issues Log or an RFI. See the example of Review Folders to the right: Trade/System Colors While Trade Contractors can use their standards established by their firm, we will establish a Navisworks Appearance Profiler Color Scheme for each trade system and other model systems in order to facilitate effective 3D Trade Coordination. The Appearance Profiler color settings will be determined in the initial BIM Kickoff Meeting. Typical Corridor Construction Template It is important to establish typical “fly zones” for installation of work. This creates a proactive efficient process not only for modeling but also for the lifecycle cost of the building. The McCarthy VDC Manager and Project Manager will review the Typical Corridor Construction Template with the team at the BIM Kickoff to determine the approach to hierarchy and placement of building systems pathways. Depending on the team’s knowledge of the documents and scope of work, the template can be agreed to at the BIM Kickoff or agreed to after the BIM Kickoff but prior to creation of overhead model content. See examples below:

Area/Model Signoff: We will conduct a “Substantial Sign-off Process” when all coordination team members are satisfied that coordination conflicts have been adequately resolved for the Engineer Review process to occur. All trade contractors involved in the coordination process shall sign McCarthy’s standard 3D Trade Coordination Sign-off Sheet for each completed coordination area. A “BIM Fly-thru Meeting” will be scheduled with the Engineering Team and Owner to review the sign-off models in Navisworks for conformance to design-intent, maintenance accessibility and serviceability. Post-Meeting, Trade Contractors will submit Coordination Drawings for Engineer Review. During and post-Engineer Review Process, Trade Contractors must address any/all comments returned both in PDF format and Model format prior to the start of pre-fabrication. Formal written documentation must be captured for all Engineer Review comments stating the comments have been addressed and satisfy the needs of the Construction Documents. If the trade contractor is utilizing pre-fabrication, the trade contractor must receive coordination drawing approval or approval from McCarthy in writing prior to any pre-fabrication to prevent rework or installation of non-compliant work. Authorized representatives are to be designated by each trade contractor and approved by McCarthy. Post-3D coordination signoff, each trade contractor is required to bring physical drawings to be signed by all other coordination team members. Each trade contractor is responsible for reproduction costs associated with production of hard copy drawings for sign-off.
