AECOM has won a contract to design the airport segment of the Honolulu Rail Transit Project in Hawaii.

The contract is worth an estimated $38.8 million.

AECOM is working with the Honolulu Authority for Rapid Transportation, the City and County of Honolulu and the Hawaii State Department of Transportation to oversee the design-build contracts for the rail system’s first two segments, in addition to the final design for segment three, which is the rail transit project’s airport segment.

AECOM will design a 5.2-mile portion of the elevated rail guideway from Aloha Stadium to the Middle Street Transit Center in Kalihi.

“AECOM is honored to work with HART and other local firms in support of this important transportation project,” said John M. Dionisio, AECOM chairman and chief executive officer.

“We look forward to leveraging our significant experience on similar projects around the world to advance the sustainable development of Honolulu’s critical transportation infrastructure.”

The rail system will span 20 miles from East Kapolei to Ala Moana Center, and is slated to open during 2019.
