Purpose and Background

This presentation was recorded at the ASCE Construction Institute Summit 2025.

This presentation explores the Chicago Transit Authority's (CTA) Red and Purple Modernization (RPM) project, a transformative infrastructure initiative designed to enhance capacity, safety, and service reliability on some of the busiest transit lines in Chicago. The RPM project involves the complete reconstruction of track infrastructure, modernization of stations, and the introduction of new technologies like a signal and communication system. The presentation delves into the complexities of urban transit engineering, emphasizing the need for phased construction to maintain service during upgrades. It also highlights the extensive stakeholder engagement, environmental considerations, and logistical challenges involved in a dense urban environment. Special attention is given to the project’s phased approach, community coordination, and sustainability initiatives. Attendees will gain insights into large-scale transit infrastructure design, execution, and the integration of modern solutions to legacy systems.
