1343562: Grade Separated Service Roadway A3/A4 at Chicago ORD Int'l Airport

Chicago Department of Aviation is soliciting bids on design and construction of Grade Separated Service Roadway A3/A4 at O'Hare International Airport (Solicitation 1343562), with proposals due October 14, 2026.

The scope encompasses a grade-separated service roadway system including bridge structures, roadway improvements, utilities relocation, and associated site work to support airport operations and enhance vehicular circulation in the A3/A4 terminal area. The project involves multiple construction phases with earthwork, structural concrete work, pavement installation, and utility coordination across the airport's operational environment. Work must comply with Federal Aviation Administration standards and Chicago municipal requirements. The contractor must manage temporary traffic control, environmental compliance, stormwater management, and phased construction sequencing to minimize disruption to active airport operations. Contractor selection criteria include qualifications, experience with airport construction projects, safety protocols, and demonstrated ability to perform in an active commercial aviation environment with constraints on equipment staging, material delivery, and work scheduling around flight operations.

The project is funded through O'Hare Modernization Program capital improvement sources. Place of performance is O'Hare International Airport in Chicago, Illinois, where coordination with active airport operations is a material performance requirement.
