This document is a Scope of Work (SOW) for a federal contract opportunity to modernize the storm drainage system at the Chicago Air Route Traffic Control Center (ARTCC) in Aurora, Illinois.
The SOW includes two projects: 1) Modernize the storm water drainage in the Administration Wing basement, which involves excavation, installing a precast concrete basin with a sump pump system, and connecting to the facility's existing storm water system; and 2) Modernize the storm drainage on the north side of the Automation Wing basement, which involves excavation, replacing storm water lines, installing new manholes and a dry swale system, and restoring the pavement and landscaping. The estimated project cost is over $650,000.
A related pre-solicitation notice was issued seeking interest from small, disadvantaged, veteran-owned, and woman-owned businesses to potentially set aside the contract. The FAA's Southwestern Region is seeking responses by 3:00pm CDT on November 25, 2024, which will be used for market research purposes only and will not result in a contract award.
