Client: Chicago Department of Aviation

Location: Chicago, IL

This project was performed in 2 phases. Phase I included the installation of two (2) new fuel transmission mains from a point starting on the northwest side of the proposed Central Deicing Facility, south along the western edge of the Deicing Facility and then east to the existing 16” lines near Concourse E and F. Prior to the 16” tie-ins, enabling work was needed to switch the feed of the Cargo Vault to feed off the existing 16” mains as well as modifying the controls at the super satellite and the East and West pump pad facility.

Phase II consisted of the construction of 2-20” transmission fuel mains, starting from the west airfield near the proposed Truck Rack Facility and traveling east toward the terminal core, south of concourse E/F. The fuel main scope included seamless single wall piping, coatings, protective backfill materials, isolation valve vaults, high point vents, low point drains, leak detection and cathodic protection systems conforming to the latest ATM standards governing aviation fuel piping. The scope also included the required system flushing and testing to ensure conformance to the latest industry standards. Existing mains were drained of fuel and filled with grout slurry with sections being demolished and removed.
