TERRA provided full site civil engineering services including construction documents, specifications, permitting, and construction assistance for Northwestern Memorial Hospital’s (NMH) new Outpatient Care Pavilion (OCP) high rise building in Streeterville. The 27-story OCP building will be a state-of-the-art medical facility located in the NMH medical campus. The civil scope of work for the OCP building includes site demolition, dimensional control, grading and drainage, utilities, stormwater detention, and construction details.

TERRA engineered the grading and drainage of the streetscape surrounding the building. In coordination with CDOT and the project’s landscape architect, TERRA engineered an ADA and CDOT compliant design that matched the aesthetic goals of the project while providing the functional needs for the building occupants and surrounding community. The streetscape improvements around the building were permitted through the Chicago Department of Transportation.

TERRA worked closely with the architect and structural engineer to design the project’s stormwater detention system. The stormwater detention system for the OCP building consists of an underground cast-in-place concrete tank located within the building footprint as the OCP is a lot-to-lot building. Stormwater from the roof enters the tank and discharges to the Chicago sewer adjacent to the building. The stormwater detention design was permitted through the Chicago Department of Water Management.

TERRA provided construction services during all phases of the project to ensure all work was in accordance with the civil design, engineering, and specifications provided. The OCP building is anticipated to achieve LEED Gold.
