|This project involved the upgrade of the mechanical systems that serve the 4-story 56,000 square foot office building, and the lower level of an adjacent 120,000 square foot parking garage. The structural portion of the project included support and bracing of a new chiller and cooling tower on the roof of the parking structure as well as bracing of new cooling units, pumps, piping, and conduits which serve both buildings. Ceiling bracing was designed and detailed in coordination with the project architect. The bracing and support of the mechanical systems were designed for immediate occupancy level forces to help ensure the facility will remain in operation during and after a seismic event.
Structural engineering design and details were provided for the seismic bracing of several CMU and steel stud partition walls on each side of the main egress corridor. This bracing was designed to meet the immediate occupancy requirements of the code as well. In addition to the wall bracing, the stair framing and interior CMU stair walls in the stair towers, were upgraded based on immediate occupancy requirements.
