HART - Airport Section Utilities by Mitch Mizokami
Utility work on Kamehameha Highway near Pearl Harbor
O
ne exciting sector of work that Nan, Inc. has recently entered into is construction on Honolulu’s Rail Transit System. Nan, Inc. was awarded the Airport Section Utilities Project Contract on August 2014 for $28 million and construction began in January 2015. The project is to relocate utilities in preparation for the new guideway for the Airport Section. The project included the relocation of 7700 linear feet (LF) of wet utilities and 5750 LF of communication, street lighting, and power duct banks through Navy, State DOT Highways, State DOT Airports, City & County of Honolulu Parks & Recreations, HART, and other Private Right of Ways. Included in the wet utility relocations were 1600 LF of 24” water line, 380 LF of 30” water line, and over 1400 LF of 1824” Sewer Line. The most challenging work on the project was the sewer line which required excavation to depths ranging from 5’ to 20’ on Kamehameha Highway, and involved replacing a manhole that collects the flows from 3 4 Nan Inc Spring 2016
separate lines. The manhole is 20 feet deep and requires the 24 hour bypassing of these lines for construction. Included in the communication and power duct banks are lines belonging to Hawaiian Telcom, AT&T, Verizon Federal, Oceanic Time Warner Cable, and the Navy. The procedure requires a significant amount of work and coordination to move over the services.
