In addition to the design of the equipment tower, CSD was responsible for the design of all access stairs. CSD worked with Nucor to provide a stair layout that met code requirements and accommodate equipment needs and access. Due to the nature of the open structure, stairs and supporting structure required unique design solutions to work with the primary structure. By partially assembling the stair towers on-site, erection of the units was simplified. This also allowed for early stair access without the need for temporary stairs.
