This critical infrastructure project was designed to improve freight and commuter rail operations, reduce congestion, and enhance regional connectivity near one of the nation’s busiest transportation hubs, O’Hare International Airport. We provided construction engineering services for this multi-year, multi-contract effort, managing complex staging, agency coordination, and regulatory compliance to ensure safe and efficient execution across active rail corridors.

KEY CONTRIBUTIONS:

Bridge Construction
We are constructing an 1,800-foot-long, 13-span railroad bridge that will carry Union Pacific Railroad (UPRR) over the Canadian Pacific Kansas City (CPKC) Railroad’s Bensenville Yard, Metra’s Milwaukee District West Line, and Franklin Avenue.

Structural Engineering
We are installing more than 40 million pounds of structural steel to support two active mainline tracks.

Substructure Installation
We placed over 16,000 cubic yards of concrete and three million pounds of reinforcing steel, supported by metal shell piles, H-piles, and nine-foot-diameter drilled shafts.

Construction Staging
We managed complex construction staging across multiple seasons and coordinated with overlapping contracts to maintain progress and minimize disruption.

Regulatory Compliance
We coordinated with the Federal Aviation Administration (FAA) to ensure compliance with 14 CFR Part 77 regulations and we submitted FAA Form 7460-1 to verify that construction elevations.

Rail Agency Coordination
We worked closely with UPRR, CPKC, and Metra to ensure all work was executed safely and efficiently within active rail corridors. We maintained uninterrupted rail service and adhered to each agency’s safety protocols and operational requirements.
