The CH2 Project is the first build to suit data center for the downtown Chicago area and is the tallest multistory data center built to date. The facility is a combination of a four-story data hall adjacent to a four-level structure housing the bulk of the mechanical and electrical equipment. The data hall is approximately 44,200 square feet per floor. The ground floor is a structural reinforced concrete slab on-grade supported by drilled piers extending about 85 feet down to bedrock that supports the electrical UPS rooms, loading dock, office and storage space. Levels 2, 3 and 4 are structural steel composite framing for support of the usable data hall space. The roof is framed with metal roof deck spanning to structural steel beams. The adjacent CUP is a cast-in-place concrete frame.
