Design and construction of 839,000 square foot addition & renovation of the GM 6-speed transmission facility, located in Toledo, Ohio. Phase 1 included approximately 532,000 sq ft addition to Plant 2; renovation of approximately 213,400 sq ft. within Plant 1, and the renovation of approximately 21,000sq ft of office area within the same plant. Phase 2 construction included the renovation of an additional 72,000 sq ft. within Plant 2. The plant was built virtually, in 3D BIM, to resolve all of the potential interferences in the design of the structure, mechanical, electrical and plumbing systems before construction. To effectively manage the process, the design-build team, along with the GM project team co-located in a collaborative environment to expedite the design and decision making. The team worked together to provide BIM (Building Information Modeling) services with a lean integrated delivery model in order to manage cost, minimize changes, meet the project schedule and produce a quality performance. The new assembly complex was designed and constructed with sustainability in mind as the team utilized LEED AP project team members. As a result of this fast track, integrated process, the first phase of the GM Toledo 6-Speed RWD Transmission Plant project started in May 2006 and was completed in August 2007. Phase 2 was completed in August 2008.
