GM Silao Transmission Expansion Program

Coordinating standards set by General Motors’ Global Facilities Group with the local design and construction standards of the actual plant in Silao, Mexico was a challenge that could have proved costly for General Motors. Without careful communication and teamwork, extensive redesign efforts could have been required to comply to all codes. SSOE’s understanding of General Motors’ Global Facilities Standards, as well as the local design and construction methods, provided a smooth incorporation of design into construction.

As a result of this close collaboration and understanding, this plant expansion project for a new, eight-speed transmission production line progressed on time and within budget through all three phases, while also meeting all client objectives. Serving as a liaison, communicating with both the Global Facilities Group and local plant officials, SSOE closely monitored the budget and schedule and quickly addressed concerns or nonconforming design elements. A 3D model was utilized throughout the program for integrated project delivery and interactive communication between teams. Representatives from SSOE’s León office attended construction meetings, facilitating the resolution of issues between design and construction.

In addition to project coordination and management, SSOE also provided the program’s Phase I bridging documents and bidding support. For Phase II of the project, SSOE partnered with a construction firm for a design / build delivery, further expediting the schedule. Phase II drawings were provided by SSOE for the transmission plant addition, office and cafeteria expansion, GSC warehouse building, and central utility complex building.

Due to the success of the first facility expansion, SSOE was requested by General Motors to design the project’s Phase III – a design / bid / build, five-bay addition incorporating as-built conditions into the 3D model. SSOE also provided construction administration services.
