UC Davis Earth & Physical Sciences Expansion
This project involved the construction of a 91,000-square-foot, three-story physical sciences teaching and research laboratory building. The earth and physical sciences expansion provides facilities for the Department of Geology, Chemistry and Physics programs, consisting of 27,570 square feet of instructional laboratories and 30,000 square feet of research, academic and administrative offices. The project required abatement and demolition of approximately 31,000 square feet of the existing structures.
The scope of BIM services included establishing policies and procedures for managing the 4D model, FTP site management, training of subcontractors in BIM best practices, multi-disciplinary trade coordination modeling for prefabrication and installation, clash detection reporting and documentation of as-built conditions.
The schedule on this project was extremely aggressive because there was a substantial amount of hazardous material abatement followed by the complete demolition of seven different structures. This work had to be completed before the test pile program could start. This was complicated when the change was made from a precast driven pile system to a displacement pile system, causing a 40-day delay to the project schedule. Flintco created a no-cost recovery plan, and we were able to recover the delay and maintain project completion. All of this work was coordinated using the BIM model.
Flintco established and managed the electronic workspace using an FTP site and file management software. Policies were developed, and subcontractors were trained in the process.
Onsite BIM coordination meetings allowed our subcontractors to coordinate the MEP systems with the architect provided model virtually. The project team was able to identify and avoid more than 300 potential field collisions; this not only reduced the number of field-generated RFI’s, but allowed for better coordination and quality of the materials being installed.
