ISTHA I-90 Smart Corridor Intelligent Transportation Systems (ITS)

JWI provided Phase III construction management and engineering services for the ISTHA SMART Corridor ITS along the Jane Addams Tollway (I-90).

PROJECT BACKGROUND

The overall project scope included the installation of Intermediate Power Distribution Center facilities, which support ITS devices such as camera, Microwave Vehicle Detection Systems, a Weigh In Motion system, and 300 active Lane Control signs. We also provided final inspection of the new fiber optic system, 14 ducts along I-90, totaling nearly 1.8 million feet.

JWI’s many roles included oversight of ITS elements and installation documentation. Our team also provided CADD drafting services for various ITS elements as well as structural drawings. We also provided Watch and Protect staff who managed and documented all fiber installs.

We provided Professional Engineering Services, site and construction inspection, monthly reporting, and documentation of daily activities, issues, materials, material testing, and construction issues.

As contractors for external projects installed the underground Fiber/ITS power infrastructure (1.5 million feet of conduit total), JWI was responsible for proofing and inspecting all hand-holes for installation quality, which involved all median conduit and Gantry bases. These were broken up into separate median contracts.

During these inspections, JWI found and documented many issues, including item differences between contracts. To better serve the project, JWI created several logs and reporting systems, which documented each item/length of conduit. This, in turn, allowed the GC to make timely and effective resolutions to keep the project on target.
