Oltmans 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 the Santa Clarita Valley.

Nestled on 60 acres in a canyon 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 will be baseball, softball, track, and football / 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 4 are a combination of conventional brace frame and masonry construction with steel substructures.
