| Abstract: |
The Honolulu Rail Transit Project (HRTP) includes the design, construction and operation of a 20- mile grade-separated fixed guideway transit system in Honolulu, Hawaii. The alignment of the project will travel through densely developed areas, over Interstate highways, streams, or existing streets. The majority of the guideway will be elevated to avoid any conflicts with the existing facilities and utilities. Honolulu Authority Regional Transit (HART) retained AECOM to perform the design of the 5.2-mile Airport Segment and 3.9-mile the City Center Segment of HRTP. Precast concrete segmental box girders erected using span-by-span with an overhead launching gantry were proposed to accommodate a 30.6-ft-wide dual track. The paper describes the background and status of the project and provides an insight of key design considerations and approaches, cost-effective structural arrangement for the precast concrete segmental elevated guideway. |
