The State of Hawaii issued a design-build competition in 2006 to meet the growing parking needs of the state’s primary airport. This eight-story design-build parking garage includes over 1,700 stalls and is connected to the existing interisland terminal garage at the 7th and 8th floors by a two-level 131 ft. bridge designed to accommodate traffic as well as moving walkways for pedestrians. Construction of the 650,000 SF. parking structure began in September 2007, and was opened to the public in February 2009.

Client Benefits

An investigative program of the project's underlying soil conditions validated that conventional spread and strip footings could be used in lieu of a deep foundation system such as driven piles, as recommended in the RFP. The modification resulted in a more efficient design, serving to reduce construction time and eliminate the negative impacts of pile driving in a confined, busy airport environment. Development of a hybrid precast/cast-in-place structure further reduced impact of site construction on the operating airport. The final building configuration which included a narrower/taller configuration than the State’s RFP documents cleared valuable land for future parking expansion or other uses required by the airport authority.

The Science and Design of Structural Engineering

BASE worked closely with the project team to evaluate several building configurations and structural schemes. The selected parking layout includes a double threaded helix ramp design that allows circulation of two levels in one revolution through the parking garage. The final configuration provided 500 more stalls than required by the design-build RFP. BASE’s understanding of multiple structural schemes, potential foundation types and efficient parking layouts helped the team gain and edge in the design-build competition.
