Structural Steel

On average we erect more than 3,000 tons of steel annually throughout the region. The projects range from supermarkets to multi-story office buildings, small additions to large hangars, and include steel stairs, mezzanines, and structural canopies. Also, with our own fleet of boom trucks and NCCCO certified operators we are able to respond quickly to your hoisting needs to get the job done.

Working with Archer Western Federal JV, CHG installed 1,400 tons of structural steel for a 110,000 square-foot hangar and operations center. The multi-level operations center consisted of wide flange columns, beams, and steel deck. The hangar portion of the project incorporated long-span box steel construction and was complicated by the fact that there was no grade slab in place during steel erection. Providing a further logistic challenge, these areas were separated by a precast concrete firewall. CHG also installed the steel stairs and railings on the project.

In addition to updates to the 1940’s vintage field house, this project added a fitness center and Olympic-size aquatic center. CHG’s work also included insulated metal wall panels and architectural sheet metal. Working on the busy campus required extensive planning, safety measures and coordination with other trades during construction.

CHG erected approximately 175 tons of structural steel, joists, decking and stairs for the 31,000-square-foot, two-story building situated on an extremely tight site in Seattle. The building houses a full-court gymnasium, two-tiered dining room, a 175-seat black-box theater, a rooftop sports field with overhead netting, and a “sky lab” that can be used as an outdoor science classroom all above a below-grade black box theatre classroom and support spaces.

CHG erected structural steel for two schools in the Bellevue School district; Spiritridge Elementary School and Tyee Middle School. The two projects involved erecting more than 1250 tons of steel, joists and metal decking. Both projects are concrete slab on grade with CMU and steel structure, steel bar joists with steel decking, rigid insulation and a single ply roof membrane or metal roofing. The exterior walls are constructed of steel studs and CMU. Exterior finishes on the stud walls are brick veneer, phenolic panels and fiber reinforced cementitious panels.
