Description

The structure at SFIA is a dramatic 860-foot-long “winglike” roof that presents its profile to cars arriving on the access road while soaring 60 to 90 feet above the floor of a cavernous ticketing hall. This project has the only “Football Truss Roof System” in the world. Smith-Emery performed all of the third party testing and inspection for SFO on this $1billion+ project. Double cantilever trusses support the center span, three-chord “football” shaped trusses. The middle sections were erected first, followed by the outside cantilever and the inside cantilever trusses. The project took 2 years to fabricate in shops in Mexico, the United States and Canada. The complex TKY Connections were fabricated under the close supervision and inspection by Smith-Emery inspectors at Specialty Fabricator XKT Engineering, Inc. in Vallejo, CA. In addition to our typical scope of work, Smith-Emery provided airport shutdown transportation inspection as the large football trusses were barged into the airport and were craned into place.
