Honolulu Rapid Transit Guideway

Honolulu High-Capacity Transit Corridor Project

The Honolulu High-Capacity Transit Corridor Project (HHCTCP) will provide a fixed guideway, rapid transit system from East Kapolei to Ala Moana Center via the Airport. The total length of the elevated guideway is approximately 20 miles and includes 21 stations and a 40-acre maintenance and storage facility. A total of 4,100 new park-and-ride spaces and four new bus transit centers will also be included. The project has been divided into four major segments: the West Oahu/Farrington, Kamehameha, Airport, and City Center Segments. The West Oahu/Farrington and Kamehameha Segments have already been awarded as design-build contracts and are currently under design.

VMS performed two studies on different aspects of the project. The first VE study focused on the 21 stations that are part of the overall system, almost all of which are configured with side platforms.  Each station has a unique palette of construction materials. A Teflon-coated, tensile fabric canopy system is a key design element that is carried between all stations and is always present at the platform level, and in some cases repeated at the station entrances. Entry plazas outside the entrance buildings include colored and stamped concrete surfaces. The total cost of the stations is approximately $600 million.

The second VE study was for the elevated guideway structure for the Airport and City Center Segments. These are intended to be delivered via design-bid-build packages consisting of guideway and utilities construction contracts for each segment. The guideway structure consists of a pre-cast, segmental concrete superstructure supported on cast-in-place columns bearing upon drilled shafts. Balanced cantilever structural sections are being considered for specific areas involving long spans. There are significant construction impacts anticipated for this work related to traffic, utilities, noise, as well as archaeological and historical resources.

VE STUDY RESULTS

For the VE study on the stations portion of the project, the VE team identified and developed 30 VE alternatives to the baseline project design. Of these, 18 were accepted for implementation and 8 were conditionally accepted, for a total PDT-validated cost savings to the project of $104.1 million.

For the elevated guideway VE study, of the 27 alternatives proposed by the VE team, 13 were accepted for implementation, 3 were conditionally accepted, and 3 required more study. The total savings to the project was estimated at nearly $110 million.

VALUE SUMMARY

Construction Cost $1,350,000,000

Initial Cost Savings $214,000,000
