Situation
GBI was awarded Phase 1 of the Kihei High School project, located in the town of Kihei on Maui. The school plans to have a capacity for about 1,650 students, with each classroom building accommodating 400 students. The future school was designed to be “net zero energy,” meaning it uses as much energy as it produces. It is scheduled to open in 2021.
Solution
The project consisted of over 311,000 cubic yards of mass excavation, with roughly half of that being solid rock (basalt). GBI created 28,000 linear feet of utility trench, installing a site drain, sewer, electrical, and fire and irrigation waterlines. Offsite improvements included traffic lane widening and Horizontal Directional Drilling 1000’ of 24” casing underneath the Pi`ilani Highway.
GBI will also be the civil subcontractor for Phase 2 of the project.
Notable
One of the unique aspects of the project is a large 2000 ft. long natural channel that will split the 66-acre campus in two. This channel will be carved into the rock surface of the campus, and utilized as a drainage path to water quality basins located at the lower portion of the school.
