City Center Utilities Relocation

The Utilities Relocation project involves the relocation of existing utilities along the rail alignment that will conflict with the future location of the columns for the rail guideway and stations.

Overview

The term “City Center” is used to describe the last segment of the Rail Project through the Dillingham corridor, Iwilei, Downtown-Chinatown, and Kakaʻako. “Utilities Relocation” refers to the removal and reinstallation of existing underground and above-ground utilities along the rail alignment in order to prepare for the construction of the remaining guideway and stations.

Once the utility relocation work is complete in the areas mentioned, the remaining guideway and station construction work can begin. In conjunction with the utilities relocation and the subsequent guideway construction on Dillingham Boulevard, HART decided in 2021 to shift a portion of the alignment to the “mauka” (or mountain) side of the street. This plan is referred to as the “Mauka Shift.” The Mauka Shift will significantly reduce the amount of the utilities that need to be relocated in that area. It will also eliminate the need for straddle-bent columns in that section of the roadway. The result of these changes is a reduction in the schedule by approximately six months and an estimated cost savings of $165 million.

Construction of the guideway will begin at the Civic Center Station location and proceed west toward Dillingham Boulevard while the utility relocation along Dillingham Boulevard is being completed. 

Key step toward completing construction

The City Center Utilities Relocation project will consist of (3) three separate contracts:
  • Downtown Utilities Relocation: This project involves the relocation of utilities from Kaaahi Street to Cooke Street, along Nimitz Highway, and ends at the intersection of Coral Street and Halekauwila Street. The contract was awarded to Frank V. Coluccio Construction Company (FVCCC), and the roadway work began in August 2022. Completion is expected in 2024.
  • Dillingham Utilities Relocation: This project involves utilities relocation work in the Kalihi-Palama area beginning on Kamehameha Highway between Middle Street and Laumaka Street to the corner of Dillingham Boulevard and Kaaahi Street. The contract was awarded to Nan, Inc., and a Notice to Proceed was issued in October 2022. Physical construction is expected to begin in November 2022. Completion is expected in 2026.
  • Ala Moana Utilities Relocation: This project will involve the relocation of utilities from Cooke Street in Kakaʻako to Kona Street near the Ala Moana Transit Center, which will be completed in a subsequent phase of the Project.

The current schedule projects a system completion date of 2031.

Major components
