Challenge: Coordinating removal and relocation of critical runway infrastructure while minimizing impacts on air travel.
Solution: Close coordination with FAA, CDA Operations, and the Contractor to ensure all work was performed in off-pea hours and any work requiring closures of Runway 9L was well planned and executed to eliminate the need for additional closures.
Result: A successful relocation of Runway 9L approach lighting that facilitates the future construction of the Elgin O’Hare Western Access.
Milhouse provided Phase III engineering services for relocating the Runway 9L Approach Lighting Sequence flashers (4753C). In addition to construction inspection and management, the CM team was responsible for coordinating all work with FAA and CDA and ensuring all construction met Tollway, FAA, and CDA standards.
This project included the relocation of O’Hare’s Runway 9L Approach Lighting Sequence Flashers (ALSF) to accommodate the future construction of I-490. The major work on the project required shutting down and demolishing the existing ALSF and constructing a new structure, including foundation piers, MSE wall, structural steel, and a grated walkway over future I-490. New ALSF light bar towers were installed on the new structure and powered by all new wires that were installed without splicing through the entirety of the existing ALSF system through both existing and new underground duct bank and handholes. This project also included site clearing, earth excavation, landscaping and erosion control.
