Trivers served as a partner for Cooper Robertson and James Carpenter Design Associates for the expanded and renovated Museum of Westward Expansion below the internationally-recognized St. Louis Arch. As part of the competition-winning Michael Van Valkenburgh master plan, the museum envisioned expansion of the underground museum to the west, creating a new western entry into the Arch Grounds and the museum.
Trivers’ involvement in the coordination with the National Park Service to maintain the integrity of a National Landmark was imperative in executing a project that is historically sensitive yet modern in function and form. Trivers worked with our design partners to solve the constructibility issues that were presented in creating a subterranean structure that needed to address high levels of security affording a structure with National Landmark status yet remain open and accessible to the public.
A great deal of coordination was required on this project. Key partners included the Gateway Arch Park Foundation, Missouri Department of Transportation, Great Rivers Greenway, The City of St. Louis, Metro, National Park Service and Explore St. Louis. In addition to collaborating with Cooper Robertson and James Carpenter Design Associates, Trivers worked closely with Haley-Sharpe Design Limited on exhibit coordination.
