- Washington & Wabash CTA Station
Our team provided engineering and construction management services for the new Washington & Wabash Chicago Transit Authority (CTA) station in the heart of historic downtown Chicago. The new station provides more efficient travel through the Loop for commuters, as well as tourists visiting theaters, Millennium Park and Grant Park. With its unique wave-patterned glass and steel roof canopy, the new structure is designed to draw visitors downtown and blend with the eccentric steel and open structure of the nearby Jay Pritzker Pavilion.
Phase 1 entailed demolition of the Madison/Wabash Station to allow room for construction of the new station. The Randolph/Wabash Station remained open to serve patrons during construction. Phase 2 involved construction of the new station. Priorities included maintaining safe vehicular and pedestrian traffic, detailed staging plans approved by the City and numerous adjacent businesses, procurement and delivery of materials within limited space, and daily removal of spoils and demolition debris. Phase 2 ended with full occupancy of the new station and a grand opening celebration. Phase 3 included demolition of the Randolph Station, and completion of all landscaping and civil street items.
This project required extensive collaboration with CTA to avoid disruptions or delays that would impact other trains entering and exiting this Loop circuit. Critical tasks included prompt approval of shop drawings to expedite the steel fabrication process; input and approval on preferred communications equipment; testing and implementation of upgrades to the train control system; and procurement and installation of uninterruptible power supplies (UPS) and proper switchgear to avoid power outages and disruptions.
