This 7,000 SF deck involved placement of steel beams that cantilevered more than 50% of their length. The structure was then decked and maintained for a period of 4 years while the Convention Center was constructed above. Following construction of the building the work deck was removed at night working from the Express lanes and mainline I-5 in restricted work windows that required careful planning. Building upon that successful installation, ZCC was awarded an additional 160 task order scope additions to construct technical steel installations in and around the new building utilizing ZCC’s in-house ironworker crews.
