As part of the planned expansion of the San Francisco Center shopping complex, the historic Emporium Dome had to be raised an additional 60 feet above its original position. Developers at Westfield and Forest City Enterprises naturally turned to Sheedy’s expert engineering staff to design and build a custom platform, temporary support tower, and hydraulic jacking system.

The landmark dome, weighing more than 250 tons, is seen here resting on the temporary tower. After the new shopping center is complete, the dome will be lowered into position atop its new foundation.
