Typical Span Length: 65 to 150 ft (20 to 46 m) and two 165 ft (50 m) continuous spans.
The HART Metro Contract 3 project is a crucial component of the broader Honolulu Rail Transit Project, focused specifically on the development of a 5.1-mile stretch of elevated guideway for a cutting-edge light rail system.
This segment of the rail network encompasses typical span lengths ranging from
65 to 150 ft (20 to 46 m) and a pair of continuous spans, each measuring 165 ft (50 m).
The substructure has been meticulously designed to withstand high seismic demands, featuring single reinforced concrete piers strategically supported on monodrilled shafts.
Employing advanced engineering techniques, the superstructure is constructed using precast segmental technology. The assembly of the superstructure occurs in a meticulous span-by-span fashion, facilitated by an overhead gantry. This innovative approach reflects the project’s commitment to efficiency, resilience, and the overall success of the Honolulu Rail Transit initiative.
SYSTRA IBT’s role was essential to the project, tasked with the responsibility for detailed design and construction engineering of the elevated guideway.
