The new 95 State office and mixed-use facility consists of a 25-story Class A tower with a 5-story podium ecclesiastical meeting house totaling 640,740 square feet. The building is located in the heart of downtown Salt Lake City, Utah. The project is being developed by City Creek Reserve Inc. with Skidmore, Owings & Merrill, architect and structural engineer, and Okland Construction as the general contractor. It is scheduled for completion in late 2021. The integrated urban design of multiple project components includes a complete rehab of the interconnecting pavilion and tunnel under State Street, connects 95 State to Salt Lake’s City Creek Center, and provides connections to neighboring Harmons retail and parking with a new solar canopy. With a client and owner team interested in the long-term performance of the facility located in a region of high seismicity and close to an active segment of Utah’s Wasatch Fault zone, SOM’s structural engineering design team responded to the design challenges of the new 392-foot-tall tower constrained on a narrow corner site using state-of-the-art performance-based seismic design methodologies and standards.
