Arts & College Preparatory Academy
The Arts & College Preparatory Academy, or APCA, is a tuition-free, public, charter high school in Columbus, OH serving students in grades 9-12. The school has a population of 260 students with a waiting list in each grade. An addition was designed to accommodate this growing demand and to add space for a middle school program.
Osborn Engineering provided full engineering services including civil, structural, mechanical, electrical, plumbing, technology, and fire protection engineering. This project includes a two story, 19,000 SF addition with six classrooms, staff offices, nurse’s office, catering kitchen, prep area and a large cafetorium and stage. A 4,800 SF renovation included repurposing the old cafeteria into classroom space. The addition is served by three rooftop units, two constant volume and one variable volume with electric reheat. An existing rooftop unit mounted at grade was relocated to accommodate the building expansion.
Osborn Engineering designed a new incoming electrical service to support the addition and refed the existing building electrical infrastructure. The design allows for a phased upgrade to the electrical system to minimize power interruptions to the existing school. The lighting design includes energy efficient LED lighting throughout the addition and renovations. A new theatrical LED lighting system and lighting control board for the cafetorium is designed to provide flexibility for a variety of future productions by the students.
The primary structural is bar joist on load bearing masonry walls. The roof of the existing building adjacent to this addition had to be reinforced to meet the additional snow drift demand. Due to budget constraint Osborn had to substitute several masonry bearing walls for steel frame with coldform infill walls. As part of the value engineering exercise, Osborn reduced the floor to floor height by one foot.
Civil engineering included renovation of the parking lot to accommodate the building expansion as well as modifying the existing utilities and ingress and egress for bus and vehicular traffic.
