Arcadia USD completed a multiphase construction and modernization project to update the entire Arcadia High School campus. MHP served as structural engineer for the project, which included extensive renovation to a majority of the campus buildings, as well as the ground-up construction of three new buildings. A new 1,200 seat Performing Arts Center with 40,000 square feet has stage capacity to support up to 150 musicians a new two-story Science Classroom Building at 42,500 square feet elevates the learning experience to modern day standards; and the new 50,000 square foot Student Services Building set the stage for an enhanced student, faculty and administration environment throughout the revitalized campus.

The Student Services and Science Classroom Buildings are two-story structural steel braced frame buildings with significant glazing and brick veneer enhancements. The Performing Arts Center incorporates heights of over 50 feet and open spans of more than 90 feet. Tall, multistory steel braced frames and fabricated structural steel long-span truss were designed to accommodate these features. Incorporation of extensive brick veneer and glazed storefront curtain wall systems required attention to deflection control, while exterior walkways transitioning to interior classroom spaces required critical detailing coordination of depressed framing and slab areas to accommodate necessary drainage.

Renovation of the remaining campus included major upgrades to all classroom buildings, the library and cafeteria as well as replacement of interconnecting walkway canopies and shade structures. Voluntary seismic upgrades were incorporated into the project scope to address vulnerabilities of buildings originally constructed in the early 1950’s. Support of new mechanical systems through addition or replacement of localized roof and ceiling structures, and rehabilitation of damaged floor and roof structures was required to accommodate new loads and address age related building issues.
