Clayco completed a 138,361-square-foot warehouse space with a 27,670-square-foot mezzanine for Health Care Services Corporation (HCSC). The precast and steel structure provides additional warehouse and office space for 300 new employees.
Clayco faced many challenges throughout the duration of the project. The brownfield site contamination was much greater than the developer knew when the land was purchased. To deal with contamination, Clayco had to haul some contaminated soils to an IEPA approved disposal landfill. The team worked with IEPA and engineers to design and contain the contaminated soils under new engineered barriers and keep surface water drainage along the south property line out of the Chicago River. In order to drive the 500 H-Piles 55 inches down to support the new building pad and foundation, the team had to work around buried obstructions, such as concrete, old heating storage tanks, and a filled in shipping canal. A 12-inch two-way reinforced structural slab was designed to sit on the H-Piles and support the heavy paper storage requirements for HCSC. The building serves as a mail processing center and electronic pamphlet production facility with record storage.
