Traylor Bros., as a member of the Shimmick/Traylor/Granite, JV team, is constructing the Honolulu Authority for Rapid Transportation’s (HART) Airport Guideway and Stations Design-Build Contract. The approximately $875 million contract is to design and build the project. The new 5.2-mile elevated guideway will extend from Aloha Stadium to the Middle Street Transit Center Station in Honolulu, Hawaii and includes four stations. This is the third in a series of projects to design and build the Honolulu Rail Transit Project, a 20-mile grade separated fixed guideway transit system with 21 stations.
The joint venture has completed three foundation load tests. The first load test involved drilling a 7.2-foot diameter drilled shaft 125 feet deep and placing rebar cage, load cells, and 4,000 psi concrete into the shaft. A second load test was completed in Ke’ehi Lagoon Park a few weeks later to a depth of 150 feet. A third and final load test using a 9.8-foot diameter drilled shaft to a depth of 250 feet was completed in October 2017.
Drilled shaft production is currently under way. Some drilled shafts will be up to 300 feet in depth due to the soft soils along the alignment. Pier column production is ongoing as well. The team is also nearing completion of the precast yard in preparation for production of the precast box girder superstructure sections, which will be erected beginning in the coming year. Other work upcoming includes station construction, utility relocation, and track installation.
Traylor will play a key role in precast and erection of the guideway segments, while providing other technical, managerial, and construction support.
