Oltmans Construction Co. was subcontracted by Castaic High School Construction Inc. and Kemp Bros. to deliver a new, state-of-the-art High School for the William S. Hart Union High School District in Santa Clarita Valley.

Nestled on 60 acres west of Interstate 5, the new campus boasts approximately 250,000 s.f. of classroom, library, administration, gymnasium, locker room, and performing arts space. Complementing the learning spaces are baseball, softball, track, football, and soccer fields as well as basketball and tennis courts.

Oltmans’ scope as the concrete subcontractor included structural concrete, concrete floor finishes, concrete forming, reinforcing, and accessories for their campus master plan. Seven (7) of the twelve (12) buildings are constructed using tilt-up construction methods while the remaining four (4) are a combination of conventional brace-frame and masonry construction with steel substructures. Using global positioning technology, zero wooden stakes were used throughout the construction of this project.

A regional emergency center, the school was designed to accommodate hundreds of local residents as a relief shelter. An on-campus storage vessel contains over 935 tons of water to serve the campus and act as a hydrant for firefighting in the Santa Clarita Valley. The 843-stall parking lot on campus doubles as a stormwater run-off evaporative basin.
