The 40-acre Northfield High School campus in Stapleton became the first new high school built for Denver Public Schools in 30 years. The high school broke tradition by grouping buildings into a campus configuration, similar to a college. The design creates flexible learning spaces, classrooms with 21st-century technology, small breakout spaces and a variety of seating areas to foster more student-teacher interaction, inquiry and creativity. The campus includes a two-story, 85,000-sq-ft academic building, a 38,000-sq-ft gymnasium and a sports complex with softball and baseball fields, tennis courts, a running track and a multisport turf field. The academic building houses classrooms, laboratories and a two-story atrium. The gym includes a basketball court, weight and fitness rooms, and locker rooms. RK Mechanical designed, fabricated and installed the mechanical systems for this high school campus project.
