The updated north and south entrances utilize curved and kinked HSS members to support floor and roof areas, with precast concrete and brick masonry cladding. Glass roof canopies cantilever from the wall system at each entrance. The interior monumental stairs required removal of sections of the existing structural system at the second and third floors. The stairs feature HSS members and steel channels boxed with plates, with glass railings and a terraced layout on the lower stair that allows students, staff, and parents to gather for presentations. Overall, the stair layout provides intuitive flow from the lower north entrance to the upper south entrance.
The underground vault is constructed with cast-in-place concrete walls and roof slabs, covered by up to three feet of earth. Invisible from the site, the vault houses electrical and mechanical equipment as well as the primary vault for natural gas service on campus. An elliptical vent structure integrates with the landscaping design at grade above the vault.
Recladding of exterior walls required careful coordination of existing conditions with new cold-formed metal framing backup walls and structural steel relief angles.
