The 80,000 sq ft building in Chicago’s Fulton Market neighborhood was constructed in the early 1950s as a manufacturing facility. Potential buyers were considering redeveloping the property for use as office space or a data center, and the owner wanted to evaluate the feasibility of adding two occupiable levels (a floor and roof deck) to the existing cast-in-place concrete structure. SGH evaluated the existing structure’s ability to support the proposed vertical addition and proposed strengthening concepts for the gravity- and lateral-load-resisting systems.
