Kihei High School, now officially named Kūlanihākoʻi High School, was a long-awaited high school project for South Maui.
Breaking New Ground
Phase 2, which was completed in 2023, entailed the construction of an administration building, two classroom buildings, a library and cafeteria building, and an athletics building.
State-of-the-Art Engineering
The two classroom buildings are identical two-story CMU structures with girls’ and boys bathrooms on each level. Each classroom building holds two modern science labs plumbed in with LP gas outlets for each of the 13 lab sinks. The DWV system for the science labs was done in Rionfuse PE acid waste piping which discharges into an acid neutralization tank.
Athletics Building
The athletics building was plumbed with a total of 53 showers for the boys’ and girls’ locker rooms. The high hot water demand was met with a 2750-gallon hot water heating plant powered by two Nyle C250 heat pump water heaters.
Cafeteria Building
The cafeteria building has a 3000 sq/ft commercial kitchen plumbed with over 50 fixtures and twin 120-gallon commercial electric water heaters. The high occupancy of the building required large boys’ and girls’ restrooms with strict tolerances on fixture locations.
Working Smarter
The majority of the DWV and copper water piping systems for the projects were pre-fabricated offsite. Our fab shop piping and hangers rods for the Cast Iron DWV & copper water piping to length utilizing a Tigerstop CNC saw system. Utilizing a CNC saw cut material waste and increased our material efficiency to over 98%. After cutting, system components were packaged and palletized by building and distributed to the site. Each package contained the necessary fittings, pipe and hangers and shop drawings for assembly onsite. Prefabricating components offsite allowed for smoother and faster installation onsite.
