Chicago O’Hare International Airport Structure Inspection – Cook County, Illinois

The complex network of bridges, tunnels, and culverts at Chicago’s O’Hare International Airport is critical to both aviation operations and ground transportation. This infrastructure supports the safe and efficient movement of passengers, vehicles, and aircraft across the airfield and surrounding roadways. The project provided comprehensive inspection services to assess, document, and preserve the condition of these essential structures, ensuring ongoing operational safety and reliability.

Detailed Inspections for Safety and Compliance
DB Sterlin conducted National Bridge Inspection Standards (NBIS) and Element Level inspections on five bridges, including three highway structures and two aircraft taxiway bridges. Structural inspections were also performed on three tunnels and one culvert. Many inspections required close coordination with the Chicago Department of Aviation to manage airside access and maintain safety during highway lane closures. These field assessments provided critical insight into the current condition of each structure and identified both immediate and long-term maintenance needs.

Engineering for Accuracy and Regulatory Compliance
DB Sterlin prepared detailed Structure Condition Reports for all bridges, tunnels, and culverts, documenting existing conditions and providing actionable recommendations for rehabilitation and repair. All NBIS inspections were completed with the required IDOT forms, ensuring compliance with FHWA, IDOT, and CDOT standards. This rigorous documentation supports public safety, regulatory adherence, and strategic infrastructure planning.

Supporting Long-Term Infrastructure Management
The inspections form a key component of the Chicago Department of Aviation’s proactive infrastructure management program. By conducting biennial and element-level inspections of O’Hare’s 14 bridges, 21 culverts, and seven tunnels, DB Sterlin provides the data needed to prioritize maintenance, plan rehabilitation projects, and extend the service life of critical structures. This program ensures that the airport’s infrastructure remains safe, operational, and capable of supporting growing aviation demands.

Built for Reliability
The Chicago O’Hare International Airport Structure Inspection project goes beyond routine compliance. By combining meticulous field inspections, detailed reporting, and expert analysis, DB Sterlin helps protect vital airport infrastructure while supporting the safe and efficient movement of passengers, aircraft, and vehicles. The project ensures that O’Hare’s bridges, tunnels, and culverts continue to serve as a reliable backbone for one of the world’s busiest airports.
