The procurement seeks a qualified firm to provide comprehensive water treatment services including professional testing, chemical provision, equipment operation and maintenance, and consulting services across multiple airport facilities. Required deliverables include monthly site visits, quarterly Legionella testing across 16 buildings, annual equipment inspections, staff training, and specialized laboratory analysis. The contractor must provide continuous monitoring and automated control of water treatment chemicals for condenser water systems, chilled water loops, hot water heating systems, and cooling towers at various facilities including the Main Terminal, Concourse B, CVG Centre, and the Preconditioned Air System. The annual condenser water make-up consumption requirements are substantial, totaling approximately 16.9 million gallons across all facilities (12.47 million gallons at Main Terminal, 1.375 million gallons at Concourse B, and 3.127 million gallons at CVG Centre), with central chilled water consumption of 20,230 gallons recorded at the Main Terminal. Questions must be submitted by January 26, 2026 at 11:59 pm, with answers posted by January 29, 2026 at 11:59 pm. Proposals are due by February 5, 2026 at 2:00 pm Eastern Time, with interviews scheduled for the week of February 16, 2026. The contract will be effective from March 1, 2026, through February 28, 2029, with KCAB retaining the option to renew for two additional one-year periods.
Minimum qualifications require the contractor to be a water treatment service company with at least 10 years of experience treating similar-sized hydronic systems, possess certified laboratory capabilities within 24-hour travel distance, and demonstrate relevant quality control certifications. The contractor must maintain a Certified Water Technologist on staff, provide contractor-furnished equipment including electronic metering pumps and a cloud-based monitoring application, and offer 24/7 emergency response within four hours of notification. The contract includes annual price adjustments based on the Consumer Price Index for the Cincinnati/Northern Kentucky metropolitan area, capped at three percent of the current annual contract price. The contractor must maintain comprehensive insurance coverage including commercial general liability ($2,000,000 to $10,000,000), automobile liability, workers' compensation, and unemployment insurance, with KCAB named as an additional insured. Kentucky resident bidders receive statutory preference in accordance with Kentucky Revised Statutes, with preference equal to the preference given by their home state.
