|Client Name:||City and County of Honolulu, Department of Design and Construction|
|Disciplines Applied:||Water & Wastewater Engineering, Surveying & Mapping, Planning & Permitting|
Faced with the possibility of a repeat of a recent break of the existing 42” Beachwalk Force Main (FM) that resulted in a major sewage spill, the Mayor of Honolulu requested that an emergency temporary line be installed within 90 days. RMTC led the design team in this emergency design build effort that included Hawaiian Dredging Construction Co. as the Contractor and City project managers facilitating the progress of the project. With the cooperation of State, Federal and City agencies and cooperation between all members of the design build team, this 6,000 lineal foot, 42” ID bypass line was placed on line in 90 days.
The bypass project was constructed in two phases.
RMTC planners prepared an emergency NPDES permit for the emergency repairs. Surveying was also provided by RMTC
