Salt Lake City and County Building seismic upgrades are now complete

The Salt Lake City & County Building is an active City Hall, so work was performed with minimal disruption to employees and guests. Big-D mitigated noise during working hours by using the traditional “wedge-and-feather method” of stone removal, instead of typical jack hammers and other power tools. This unique method allowed crews to perform work during business hours.

The work conditions in the basement were challenging. Crews were often forced to crouch and crawl to install the receiving system components around the 447 base isolators supporting the building. Big-D is proud to report that 14,400 labor hours were performed on this project with no injuries recorded during construction. The efforts of VCBO Architecture, Reaveley Engineers, and City personnel for helping Big-D deliver the project on time and under budget.
