In 2012, the Honolulu Rail Transit Project began the construction of a 20-mile elevated rail line. The rail system seeks to alleviate significant traffic issues affecting Hawaii’s most congested city. Kiewit was tasked with the design and construction of the elevated rail guideway. In order to accelerate the construction timeline and maintain a high-level of quality, Kiewit selected a segmental precast span-by-span construction technique to complete the project. The first 10-miles of guideway will consist of 5,200 guideway precast segments which are casted at an off-site casting yard, then delivered onsite for installation. Kiewit designed a twin underslung girder system to complete the span-by-span construction. The installation of segments weighing up to 50 tons each requires a positioning system with a significant amount of force and precision.
