A joint venture of Fluor and Walsh Construction has won a $1.2bn contract from the Chicago Transit Authority (CTA) to design and build the $2.1bn Phase One of the Red and Purple Line Modernization (RPM) Program.
The RPM is a plan to rebuild the century-old rail lines north of Belmont and improve CTA rail service. The largest capital project in CTA history will expand capacity and improve infrastructure along the most used rail lines in the region.
Under the contract, approved by the Chicago Transit Board, the Walsh-Fluor team will be responsible for building new Red and Purple line track infrastructure.
The project includes designing and building new elevated tracks along a 1.9-mile section in Chicago, including new bridges, support structures and existing tracks.
Work will include reconstruction of the Lawrence, Argyle, Berwyn and Bryn Mawr Red Line stations into larger, 100% accessible stations and century-old track structure totalling six miles.
The team will also build a rail bypass at Clark Junction north of Belmont station to improve service reliability on the Red, Purple and Brown lines, increase train speeds, ease overcrowding on rail cars, and provide capacity for projected future growth.
The JV will install a new signal system on 23 track miles between Howard and Belmont, which will improve CTA train flow and increase service reliability.
The Walsh-Fluor joint venture and the CTA will hold public meetings in 2019 as design and construction planning begins on the exciting project. They will work with local communities and CTA customers on construction impacts to neighbourhoods and service.
Announced in 2014, the $2.1bn RPM Phase One project is fully funded by federal and local money. The project will begin in the first quarter of 2019 and is scheduled to be completed in early 2025.
Stantec Consulting Services has been appointed as the team’s designer.
The Chicago Transit Board has also approved a separate contract of $20.9m to HNTB Corp as programme manager for the Red Line Extension (RLE).
The three-year contract includes seven one-year options to extend the contract, to provide consistent support in future phases of the project.
The proposed 5.3-mile extension will include four new stations near 103rd Street, 111th Street, Michigan Avenue and 130th Street.
