NIGP 91818: Boiler Chemistry Consulting

NIGP 91818 Boiler Chemistry Consulting, an Item code, encompasses preventative maintenance, chemical testing, emergency repair services, and operational support for chiller and boiler systems at state and local government facilities. Recent solicitations show state and local governments buying monthly chemical testing (hardness, alkalinity, chlorides, nitrite, phosphates, pH, conductivity, and biological activity monitoring), routine preventative maintenance on cooling towers and boiler equipment, startup and shutdown procedures, alarm documentation, 24/7 emergency repair response, and system commissioning. Issuing bodies include city housing authorities, community development authorities, and county facilities departments; the City of Phoenix Housing Department and City of Madison Community Development Authority both solicited chiller and boiler maintenance and replacement work under this code in recent months. Work is performed at multiple government-owned residential and operational properties, with contractors required to hold state-level licensure (Arizona Registrar of Contractors or equivalent), manufacturer-specific certifications such as NBIC Code "R" Stamp authorization, and often Davis-Bacon prevailing-wage compliance.

The code shows recent activity concentrated in Arizona, Wisconsin, Georgia, and Florida. The City of Phoenix Housing Department posted IFB FY27-086-03 for chiller and boiler system maintenance across multiple City-owned housing properties with offers due August 24, 2026, requiring five years of prior experience, five-year firm fixed pricing with Davis-Bacon labor rates, and mandatory 24/7 emergency response at four-hour on-site target. The City of Madison Community Development Authority issued RFB 15052 for boiler and domestic hot water system replacement at three residential properties with bids due July 17, 2026, specifying furnishing and installing six Lochinvar Knight high-efficiency boilers and associated equipment on a fixed-fee, all-inclusive, not-to-exceed basis with weekly certified payrolls and prevailing-wage compliance. Both solicitations carried background screening requirements due to unescorted access to private residences and mandated comprehensive insurance coverage within 14 calendar days of award.
