The scope of services for this project consisted of Phase II professional engineering services including structural engineering design, detailing, and CADD support services for the rehabilitation of this 100-year-old facility. DB Sterlin’s scope of work included the preparation and submittal of contract documents involving structural analysis of four (4) Main Spans of the new track work and its supporting structures. Design calculations, complete detailing, and applicable construction documents were completed for these supports, including the column splice design, bent design, bearing supports, and required bracing, for the complete Construction package, along with providing specifications and special provision documents. DB Sterlin also provided Quality Control/Quality Assurance reviews of the pre-final plans, quantities and cost estimates, staging, and temporary shoring construction documents prepared by HNTB for the balance of the Project. DB Sterlin is responsible for future shop drawings reviews for portions of the new main track work and building construction to be completed.
Wilson Station is a major transfer station on the Chicago Transit Authority Red Line, with more than two million passengers each year. The $203 million project, due to be completed in 2014, will replace the existing station built in 1923. The completely rebuilt, modern, and the accessible station will serve as a new transfer point between Red and Purple Express service and will include the rebuilding of the stationhouse, construction of two new auxiliary entrances, and dual platforms to allow transfers between Red and Purple Line service, significant track and structural work, and restoration of the 1923 stationhouse façade. The project is part of the CTA’s $1 billion modernization and expansion of the Red Line.
