General Motors Technical Center

Warren, Michigan

BCA's work on the multi-billion dollar restoration and rehabilitation of the nearly mile-square, 60-building complex began with a Historic Preservation Master Plan that included extensive research in drawing and photographic archives and resulted in a historical evolution and alteration study of each building; a façade survey of all buildings; comprehensive exterior and interior photographic documentation; restoration designs; and a view-shed analysis for proposed modifications and new construction. 

The Master Plan became the basis for BCA's National Register nomination for the entire campus, which successfully argued for a period of significance that spanned the years 1949 through 1970.

BCA subsequently oversaw the Historic Preservation Certification Application that enabled General Motors to secure a one billion dollar tax credit. Concurrently, BCA designed and oversaw the restoration and rehabilitation of the curtain wall systems on the original Saarinen-designed buildings. 

The Michigan Historical Center Foundation awarded the project the 2006 Governors Award for Historic Preservation.
