The Red Line is the backbone of Chicago’s rail system, and in 2012, the CTA began its CTA Red Line South Track Renewal project. Cotter provided construction management for this project. The CTA suspended rail service from the Cermak-Chinatown station to 95th Street station for five months in order to completely rebuild and renew the Red Line South infrastructure.
The $425 million project, which provided faster and more reliable service for Red Line riders, involved a complete reconstruction of the supportive track infrastructure down to its foundation, a complete rebuild of tracks, new ballast (the rocks below the tracks), and drainage system improvements. Some stations also received improvements ranging from new canopy, paint, and lighting upgrades to new benches and bike racks. The stations at Garfield, 63rd, and 87th received new elevators, making all stations on the Red Line South wheelchair accessible.
As a subconsultant for this project providing construction management services, Cotter’s field inspectors and engineers monitored and inspected work performed by the contractor, verifying and ensuring conformance with contract documents.
