Eugene Sawyer Water Purification Plant

CTLGroup performed a condition assessment of the precast concrete channel slab roof system. Deterioration observed during the visual review included spalled flanges with exposed corroded reinforcement, longitudinal cracking in the flanges, web spalls, and excessive web cracking.

The City of Chicago commissioned a comprehensive removal and replacement program for the roof of the plant. As part of the program, CTLGroup was retained to design a more durable channel slab, which included high performance concrete and enhanced concrete cover over the reinforcing steel.
