Com-ED Midway Load Conversion – Quality Inspection of Conduit and Manhole Installation

Chicago, Illinois

DB Sterlin performed site inspections of conduit and manhole installation for ComEd’s Midway Load Conversion project near Central Ave. from Archer to 57th St. and at locations along 63rd St. in the same area. The inspections were quality checks to ensure that ComEd’s facilities were being installed per contract plans and appropriate ComEd specifications, and to note any deviations. Horizontal and vertical spot checks of proposed facilities were measured, as well as observation and confirmation that utility crossings met appropriate separation requirements. The restoration was also observed to ensure adherence to plans and permit requirements, and overall traffic safety and site conditions were noted. DB Sterlin coordinated with 2 different contractors at 4 to 5 sites.

The scope of services included the installation of concrete encased duct packages, installation of cast-in-place and precast ComEd manholes, including manholes with excavation over 12’ deep requiring extensive shoring systems, and a portion of the conduit being jacked and bored under an at-grade railroad crossing.
