NIGP 94151: Heat Exchanger Maintenance and Repair

NIGP 94151 Heat Exchanger Maintenance And Repair, an Item code, covers the annual cleaning, inspection, and performance testing of shell and tube heat exchangers in industrial and utility facilities, including eddy current testing and tube removal services. The City of Tampa's procurement for condenser cleaning and testing at its Waste to Energy facility exemplifies the scope: comprehensive tube cleaning (main condenser, dump condenser, and LP heater tubes), mandatory nondestructive testing on a percentage of tubes, and associated labor and material costs. State and local governments solicit this work primarily through cities and municipalities operating waste-to-energy plants, power plants, district heating systems, and other thermal-generation or industrial facilities that depend on heat-recovery equipment for ongoing operability.

The most recent activity in this code comes from Florida, specifically the City of Tampa's IFB for condenser cleaning and testing at its McKay Bay Waste to Energy facility (Solicitation 25P00355), due October 2, 2025, with an estimated contract value of $90,000 and a three-year term plus optional two-year renewal. The City of Tampa solicitation includes provisions for Underutilized Women and Minority Business Enterprise and Small Local Business Enterprise participation, with bid discounts up to 5% for U-WMBEs and SLBEs. Bidders must demonstrate a minimum of five years of experience in shell and tube condenser cleaning and eddy testing and comply with OSHA regulations and facility-specific health and safety protocols, with Commercial General Liability, Automobile Liability, and Worker's Compensation insurance required.
