As part of a joint venture, Traylor 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.
Drilled shaft production is nearly complete. Some drilled shafts are up to 350 feet in depth due to the soft soils along the alignment. Pier column production is ongoing, with more than 230 columns required along the alignment. The precast yard is up and running, producing segments more than 30 feet wide and weighing between 45 and 65 tons. In addition to casting more than 2,700 segments, the yard is also producing the 5,400 permanent sound walls that will be placed along the entire alignment.
To complement precast operations, three overhead gantries were custom designed and fabricated in Italy. Two gantries are currently in operation with over 60 of the 210 total spans erected.
Other upcoming work includes station construction, utility relocation, and track installation.
Traylor is playing a key role in precast and erection of the guideway segments, while providing other technical, managerial, and construction support.
