Professionals Associated selected as surveyor of record for the largest construction project in CTA History

 

Professionals Associated has been selected as the surveyor of record for Phase I of the CTA RPM project – the largest construction project in CTA history.

The CTA RPM (Red and Purple Modernization Program) is a multi-year, multi-billion-dollar construction project. The project consists of rebuilding the Lawrence, Argyle, Berwyn and Bryn Mawr stations, and all of the tracks and support structures for more than a mile adjacent to the stations. The project also includes a Red-Purple Bypass north of Belmont station trains, which will modernize the century-old Clark Junction where Red, Purple and Brown Line trains currently intersect.

As the surveyor of record for this project, Professionals Associated will be responsible for controlling the location and positioning for all phases of the project, including the new stations and their associated supports, new tracks, flyover support structures, and utilities associated with the project. Professionals Associated will also be responsible for establishing a monitoring program for structures in and around the project to check for any movement that would have an adverse effect on those structures while construction is taking place.

Professionals Associated was selected from a wide field of candidates by the Walsh/Fluor design and general contracting joint venture based on our previous experience in railroad infrastructure surveying. We have served as the surveyor of record for both the CTA Dan Ryan Red Line Reconstruction and the Ravenswood Loop Connector projects. Our ability to provide skilled personnel for the project, real-time sharing of project information and data between our field and office, use of modern surveying equipment and software, and competitive pricing to provide the best value were also determining factors.
