HONOLULU'S STREET RELIEF
Constructing a new relief sewer under Honolulu's busy Nimitz Highway was a challenging proposition for city and county officials. The $15 million pipeline was bid as an open-cut project, but a creative contractor felt that microtunneling offered many advantages because of poor ground conditions, the potential for soil and ground water contamination, and the possibility of long delays on the busy highway. This article describes that winning contractor's alternative microtunneling methods. Jet grouting was employed to stabilize the weak subsoils and support the new pipeline. An Iseki Unclemole system with a high torque capacity and an oscillatory rotating cutter head was used to excavate through the jet-grouted soil and coral, resulting in a pipeline that was straighter than could have been laid by open trench construction. Both the city and contractor saved money and accelerated their construction schedules with the microtunnel and jet grouting approach.
