“City Center” is a term used to describe the last construction in the third segment of the Rail Project, comprised of the Dillingham Boulevard, Iwilei, Downtown, and Kakaako areas. The “Utilities Relocation” project refers to the relocation, or movement, of existing underground and above-ground utilities along the rail alignment to prepare for the City Center Guideway and Stations and the future location of the guideway columns.
The City Center Guideway and Stations construction work, a design-build and contract award, is to be procured and anticipated to be awarded in 2023. Once the utility relocation work is completed in these areas, the City Center Guideway and Stations construction work will begin.
The City Center Utilities Relocation project will consist of (3) three separate contracts:
- Downtown Utilities Relocation: This project involves utilities relocation work from Kaaahi Street to Cooke Street, along Nimitz, and ends at Coral Street along 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 and Laumaka Streets 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. Actual construction is expected to begin by the end of 2022. Completion is expected in 2026.
- Ala Moana Utilities Relocation: This project will involve relocating utilities from Cooke Street in Kakaako to Kona Street near the Ala Moana Transit Center. Procurement for this work will begin at a later date.
The current schedule projects a system completion date of 2031.
About the utilities relocation construction work:
The major scope elements for utilities relocation include storm drainage, sanitary sewer, water main, gas/fuel, electrical and communications infrastructure, and roadway improvements.
Construction crews will “pothole” to confirm the location of the underground utilities, “jet grout” to control groundwater during construction, excavate and place new utility infrastructure, switch the services over to the new infrastructure, remove the old utility lines, and backfill and repave the street.
