Dollar Value of Project:
The new State/Lake CTA station will replace the more than 100-year-old existing structure with a modern, fully accessible rail hub with wider platforms and a host of customer amenities, built to 21st Century design standards. It includes wide balconies open to the public facing north and south that create scenic overlooks of State Street, including an up-close view of the landmark Chicago Theater. The bold architectural design is in keeping with recent signature stations, such as the 95th Street Terminal, the Washington/Wabash station, and the Damen Green Line station.
The scope of work for this project includes Phase II design engineering for the preparation of the plans, specifications, and estimates (PS&E),for the rebuilding of the elevated Chicago Transit Authority (CTA) station located at the intersection of State Street and Lake Street in downtown Chicago.
Garza Karhoff Engineering is providing structural engineering services for the design and construction plan development for the new platform design. The existing platform structure is to be removed and completely rebuilt using structural steel beam, rolled wide flange, angles, and built-up steel box sections, supporting precast concrete planks for the typical spans and cast-in-place concrete for the center span. The platform will consist of nine spans of approximately 50 feet and one span of 86 feet.
