SPOKANE INTERNATIONAL AIRPORT PARKING GARAGE ADDITION
Park It Here: More long-term airport parking for frequent fliers
Spokane International Airport increased their parking capacity by developing a standalone, five-story concrete parking garage connected by bridges at each level to the existing, adjacent parking garage. An expansion joint was installed to separate the two buildings. For this design-build project, DCI was the civil and structural engineer of record for the site and building. The structure is a hybrid of precast concrete beams and columns supporting cast-in-place post-tensioned slabs. Cast-in-place concrete shear walls provide lateral resistance against wind and seismic forces.
DCI recommended this hybrid concrete design to accommodate the GC’s construction budget and aggressive construction schedule (10 months) and to minimize operational maintenance costs for the facility.
The civil team developed the site’s stormwater system, grading, drainage, horizontal & vertical control details, street and exit revisions, erosion control, and parking stall striping plans.
- Construction was completed in 10 months.
- The parking garage has a total of 1,140 parking stalls.
- The structure is a hybrid of precast concrete beams and columns supporting cast-in-place post-tensioned slabs.
- The lateral force resisting system is an arrangement of concrete shear walls, located away from the corners of the structure to reduce slab cracking from volume change resistance.
