SQN provided quality management support for CTA’s Garfield Green Line Station Rehabilitation project. The project restored the stationhouses to a state of good repair and enhanced key components of the station, including the existing operational station, bus turnaround, historic 1892 former “Alley L” station and track structure, roadway, and median. Additional improvements included elevator and escalator upgrades and platform canopy extensions.
