Sea-Tac Airport’s new rental car facility required more than 100,000 cubic yards of concrete and 15 million pounds of rebar.

Consolidated Rental Car Facility

Location: SeaTac

Owner/developer: Port of Seattle

Project team: Turner Construction Co., general contractor; Demattei Wong Architecture, architect; KPFF Consulting Engineers, structural engineer; The Conco Companies, concrete contractor; Miles Sand and Gravel Co., ready-mix contractor

The Consolidated Rental Car Facility, which will support all the rental car operations for Seattle-Tacoma International Airport when it opens on May 17, was built on a 23-acre site at International Boulevard and South 160th Street.

The 2 million-square-foot concrete structure has five levels and can hold more than 5,400 vehicles. Each level is approximately 400,000 square feet.

Ready and return activities take place on the first four levels. A pair of spiral ramps provide vehicle access to each level. A quick-turnaround facility on each level includes fueling stations, car washes and a support area.

The fifth level houses an enclosed customer service building with storefronts for the rental car companies and shuttle drop-off and pick-up areas.

In all, the facility required more than 100,000 cubic yards of concrete and 15 million pounds of rebar. Its detention vault runs the length of a football field, and there are six 20,000-gallon buried fuel tanks.

The project was awarded a LEED silver rating, with points earned for using regional materials, exposed exterior walls and structure surfaces, and use of recycled materials such as the fly ash in the ready-mix concrete.
