This project requires a contractor to provide all labor, materials, and supervision for replacing gas-fired boilers and steam generators with steam-to-hot water heat exchangers and duct-mounted humidifiers at Green House Homes 201 and 202, located at the Captain James A. Lovell Federal Health Care Center in North Chicago, IL. Work must be phased to minimize disruption to occupied homes and FHCC operations, with humidifier installation limited to a one-day event per home. Due to hydronic re-heat system sensitivity, all work must start and finish between May and October. The project budget is between $500,000 and $1,000,000, with a completion timeline of 270 calendar days after notice to proceed. This opportunity is set aside exclusively for Service-Disabled Veteran-Owned Small Business (SDVOSB) firms.
