NIGP 96241: Heat Treating and Tracing Services (Including Refractory Dryout)

NIGP 96241 Heat Treating and Tracing Services (Including Refractory Dryout), an Item code, encompasses mechanical system installation and replacement work at municipal and school facilities, though recent state and local solicitations show activity narrowly concentrated in HVAC and irrigation infrastructure projects rather than the legacy thermal-processing scope the code name suggests. State and local governments buy complete system replacements, including equipment removal, installation of controllers and components, ductwork and piping integration, electrical and plumbing work, and system commissioning under this code. Issuing bodies include municipal public works departments and independent school districts; School District U-46 in Kane County, Illinois and the City of DeBary, Florida appear as recent buyers. Solicitations specify compliance with current energy codes, prevailing wage requirements where applicable, mandatory pre-bid conferences, performance and bid bonds, insurance thresholds, and liquidated damages for schedule delays.

Recent opportunities span Illinois and Florida. School District U-46 issued IFB 4042526 for Heat Pump Replacement at Fox Meadow Elementary School in South Elgin, Illinois with a sealed-bid submission deadline of February 25, 2026 at 1:00 PM CST through the Bonfire eProcurement System, requiring a mandatory pre-bid meeting on February 10, 2026, substantial completion targeted for August 7, 2026, and liquidated damages of $1,000 per calendar day for delays. The City of DeBary, Florida posted Bid 03-15 for Rob Sullivan Park Irrigation Improvements, converting irrigation infrastructure to a Hunter system with an engineer's estimated cost of $90,000, a 45-calendar-day completion requirement, a mandatory pre-bid conference on March 25, 2015, and a bid submission deadline of April 10, 2015 at 10:00 AM. Both solicitations required comprehensive contractor qualifications, extensive technical compliance documentation, and coordination with existing building or park systems.
