Reagan Memorial Tollway (I-88) Roadway and Bridge Rehabilitation Construction Management
In 2012, the Illinois Tollway launched the 15-year, $14 billion “Move Illinois” capital program to improve mobility and access, relieve congestion, reduce pollution, and create new jobs throughout the region. The $360 million Reagan Memorial Tollway (I-88) repair and improvement project is part of this capital program.
IEI was contracted by the Illinois Tollway as a prime engineering consultant to provide Phase III construction management and engineering services (inspection and supervision) for on-call contract task orders for the I-88 Roadway and Bridge Rehabilitation Project, overseeing a $42 million construction budget. IEI managed two primary task orders for this project.
The initial task order included mainline patching and rehabilitation, structure rehabilitations, ditch grading, drainage improvements, and miscellaneous safety improvements along 10 miles of I-88. The second Task Order, which is expected to be completed in Fall of 2021, encompasses the rehabilitation and improvement of an additional 5.5 miles of I-88, the removal of a deteriorated 3-span bridge over the Illinois Prairie Path, and the installation of a cast-in-place three-sided box culvert. IEI was involved in both the design and construction of this project.
The Construction Management phase of this project involved managing cost and schedule and the coordination of information with stakeholders. The site conditions made it critical for for the entire team, including the Tollway PM, the GEC, the Designer, the CM, and the contractor to coordinate activities. IEI implemented CM techniques that helped with constructability, staging, and scheduling for the construction of the culvert.
- To reduce the impact of construction on I-88 and Prairie Path users, the existing bridge was removed under staged construction utilizing a counterflow lane to maintain full traffic lanes. Additionally, the roadway embankment was constructed filling around the culvert to allow for the Prairie Path to remain open to bicycles and pedestrians.
- By re-engineering the original precast design with a cast-in-place design, obstacles such as crane use in proximity of overhead power lines, limited access, and lack of staging areas were eliminated, increasing safety and helping to streamline the job’s schedule.
- A section of the culvert framework was built on a sliding railing system. After pouring the first section, the entire framework was pulled out and repositioned to pour the subsequent three sections, helping to save significant construction time.
- The team was able to place concrete with a conveyor that was moved for each section of a pour and lifting the machine under the bridge and using outriggers on the concrete blocks.
- Haul roads were constructed on either side of the tunnel, behind the existing piers, allowing for progress to continue on wing wall construction and final finishes while maintaining forward progress of the tunnel itself, all which contributed to the project’s timely completion.
- The team’s plan for construction sequencing took advantage of the dry seasons and allowed for a gain of 35 days of float in the construction schedule.
By applying our signature INGENUITY to all aspects of this project, we were able to provide more scope within the same schedule, leading to greater value delivered. Construction of the pedestrian culvert was completed on time and within budget opening the Prairie Path to users on time allowing the Tollway to meet commitments to project stakeholders. IEI’s team received a 4.26 of 5.00 (Exceeds Expectations) performance evaluation from Illinois Tollway for this project.
