Cresthill Middle School was a phased addition and renovation project. The original structure, built in the 1980’s was in need of new mechanical and electrical / life safety systems and functional/aesthetic architectural upgrades to accommodate the school district’s learning model. To accomplish this, the project scope required the construction of three new additions and the complete interior renovation of 120,000 square feet of the existing building. The project additions consisted of one two-story classroom and science lab addition, one single-story administration addition, and one two-story commons and cafeteria addition. The classroom and administration addition were steel frame with masonry veneer and the commons addition was built utilizing all structural masonry. The existing building was renovated and completely reconfigured to provide eight new science rooms with prep labs, four new computer rooms, twenty-four new classrooms, twelve new flex-group rooms, fourteen new multiple fixture restrooms, and a completely new administration area. Renovation work included all new ceiling systems, new variable air volume terminal units with DDC Control, new boiler system and hydronic piping, new direct / indirect lighting with occupancy sensor control, new audio visual systems, a complete new fire alarm system, reconfiguration and updating of the fire suppression system, fire life safety upgrades including spray fireproofing and construction of fire rated assemblies, wall covering, new carpeting, new VCT, MMA acrylic resin flooring, new casework, new code compliant stair and rail assemblies at all common stairs, new wood flooring in main and auxiliary gyms, and interior painting throughout.
