DB Sterlin served as the civil utility design lead and was responsible for the structural design of various elements of three new CTA structures. Our responsibilities included designing and coordinating all utility connections for the Loomis Stationhouse, Racine Stationhouse, and Morgan Substation. This involved three sanitary sewer connections/force main connections and three electric service connections, all of which were directionally bored under I-290, as well as three water service connections to the new buildings. DB Sterlin also coordinated all utility permits with the CTA, the City of Chicago, and the Illinois Department of Transportation. They performed value engineering for the sanitary sewer design, including evaluating the lift station design and considering options for the electrical equipment pad location for the Morgan substation. Additionally, DB Sterlin developed structural repairs for the existing platform and designed a new reinforced concrete ramp and platform extension.
This program includes major track renewal, renovation of Racine Station, and construction of a new substation at Morgan Street. The scope of services includes the reconstruction of the Racine stationhouse, which will feature a new elevator and stairs, a platform extension, repairs to the existing platform, and a new ADA-accessible ramp at the Loomis entrance as well as reconstruction of the Loomis stationhouse. Traction power upgrades for the new Morgan Street substation and in-kind upgrades at the existing Hermitage substation are also included. Modifications to the existing overpass bridge structures at Loomis, Racine, and Morgan are required and will require coordination with CDOT and IDOT
