Charleston Airport Parking Structure

Project Size: 990,000 square feet

Architect: LS3P Associates LTD, Charleston, South Carolina

Developer: Charleston County Aviation Authority, Charleston, South Carolina

Contractor: Roy Anderson Corporation, Gulfport, Mississippi

Concrete Contractor: Baker Concrete, Gulfport, Monroe, Ohio

Charleston's accelerated growth in new industries and tourism called for a massive expansion in parking capacity at the Charleston International Airport.

The project is a five-level free-standing parking structure that contains 3,005 parking stalls. A long span framing system provides column free parking. Ductile frames with high strength rebar were used for seismic resistance in both directions, eliminating all shear walls and maximizing sight lines. Structural durability was enhanced through use of custom designed mixes which reduced slab shrinkage during construction and minimized porosity of the hardened concrete.

External helix ramps, one for entering the garage and one for exiting, allow for flat parking areas throughout the garage. Foundations include auger cast piles, pile caps, and grade beams, which were tied together below ductile frames to reduce seismic overturning moments and limit the number of tension piles to less than 4% of the total pile quantity.
