Red Purple Modernization (RPM)- Phase I
Project Overview: A $2.1B program to rebuild a 9.6 mile stretch of track, stations, structures, and related systems to double passenger capacity and bring the Red and Purple rail lines into a state of good repair for the next 60 to 80 years. Benefits include reduced travel times, improved access to job markets and destinations, as well as improved access to people with disabilities. CTA RPM - Phase I includes Lawrence to Bryn Mawr Modernization (LBMM) which rebuilt tracks and support structures throughout Lawrence, Argyle, Berwyn, and Bryn Mawr Stations and Red-Purple Bypass (RPB) which constructed a rail bypass north of Belmont Station allowing CTA to address capacity constraints caused by an outdated rail intersection used by 3 CTA rail lines.
Our Scope: As a subcontractor to Walsh Fluor Design Build Team (WFDBT), CSS managed testing & commissioning efforts, tracks resolution of deficiencies, and maintains signal maintenance logs. CSS successfully performed commissioning services and tie-in circuitry cutovers of Addison Relay House and Barry Relay House. We further support the Design Build Team by conducting QA audits, coordinating Testing & Inspection (T&I) efforts, and assisting in systems related Safety & Security verifications.
Red Line Extension (RLE) - Mainline Design Build Project
Project Overview: A $2.9B project to extend 5.6 miles of track beyond the current 95th St. Terminal to 130th St. with accessible stations at 103rd St., 111th St., Michigan Ave. near 115th St., and 130th St.. The largest project in CTA history, RLE aims to provide faster connections from the Chicago's far south side to the rest of the city, increase access to affordable transportation for residents, and serve as an economic catalyst for the community.
Our Scope: As a subcontractor Walsh Vinci Transit Community Partners (WTCP) and partners, CSS is performing signal systems design services, signal manufacturer field & resident engineering services, and signal and communications Safety & Security Certification support services on the project.
