DB Sterlin’s responsibilities included supervision and management of construction activities involving the drainage system (catch basins, manholes, and underdrain installation), electrical system (duct bank, manholes, cable pulling, precast foundation), track installation, track gauging, and third rail installation and gauging, signal installation, and performing trials with test trains. The work included documentation of daily activities, construction inspection, project coordination, and other duties that required the services of an engineer to successfully complete this project on a timely basis and in accordance with CTA requirements.

This project consisted of a full replacement of the track bed on the south Red Line and an upgrade of eight of the stations south of Roosevelt Road. Replacement of the track bed included ties, rail, third rail, ballast, and drainage systems. Station improvements included new canopies, paint, and lighting upgrades as well as new benches and bike racks. Additionally, new elevators were installed at Garfield, 63rd, and 87th stations, making all stations on the South Side Red Line ADA accessible.
