AECOM Technical Services Inc., a subsidiary of AECOM Technology Corp., is working on a $43.9-million contract from the Honolulu Authority for Rapid Transportation to provide design services for a portion of Hawaii’s Honolulu Rail Transit Project.

AECOM is responsible for the final design of the City Center Section — the 3.9-mile fourth and final segment of the project. The contract includes all of the structural and civil design aspects of the aerial guideway, except for the stations and systems components.

The overall project has an estimated construction value of $5.17 billion and will run 20 miles in its entirety, from Kapolei to Honolulu’s Ala Moana Shopping Center. It is slated to open during 2019.
