About this file
This is a Construction Cost Estimate document for the Kenton County Airport Board's North & South Aircraft Rescue and Firefighting (ARFF) Stations Mechanical, Electrical & Plumbing (MEP) Modifications & Tank Installation project dated June 13, 2025. The project involves comprehensive renovations at both ARFF facilities to transition from Aqueous Film Forming Foam (AFFF) to Fluorine Free Foam (F3). The North ARFF station renovation encompasses 1,270 square feet in the truck bay and 116 square feet in the mezzanine tank area, while the South ARFF station includes 1,350 square feet in the truck bay and 274 square feet in the mezzanine tank area. Primary deliverables include demolition of existing systems, installation of new 2000-gallon polyethylene foam storage tanks, centrifugal chemical processing pumps, distribution piping, electrical modifications including wiring and conduit installation, and associated infrastructure upgrades. The mandatory pre-bid meeting and site visit is scheduled for November 6, 2025, at 10:00 am at ARFF South Station, with bidder questions due by November 20, 2025, at 11:59 pm and final bid submission deadline of December 4, 2025, at 2:00 pm. The contractor must commence work within 10 calendar days of receiving the Notice to Proceed, with design and construction completion targeted for July 2026.
The total estimated project cost is $229,915, with the North ARFF station estimated at $127,937 ($92 per square foot) and the South ARFF station at $101,977 ($63 per square foot). Direct costs total $154,851 across both locations, with Division 21 Fire Protection comprising the largest expense category at $120,000, followed by Division 5 Metals at $11,800 and Division 26 Electrical at $11,951. The estimate includes General Conditions at 12 percent, General Contractor Overhead and Profit at 18 percent, and a 15 percent contingency. The project is funded through CAPEX with a total approved budget of $660,000, which includes the $229,915 construction estimate plus $109,000 contingency reserve. A proposal bond of at least 5 percent of the total bid amount is required from all bidders. Known project risks include potential reduced fire suppression effectiveness, higher costs due to foam product availability constraints, required firefighter retraining, and specialized storage and disposal requirements for the new foam system.
