NIGP 49092: Thermal Analysis, Thermogravimetry, and Thermal Conductivity Apparatus

NIGP 49092 Thermal Analysis, Thermogravimetry, and Thermal Conductivity Apparatus is an Item code under which state and local governments procure specialized instrumentation and field services for measuring thermal properties of materials, geological formations, and engineered systems. Recent solicitations show two distinct procurement patterns: university research institutions acquiring laboratory instruments for thermal conductivity and gas analysis (including sensor upgrades and software), and municipal engineering departments engaging contractors to conduct field thermal conductivity testing in support of building energy retrofit feasibility studies. The City of Madison's geothermal test bore-well project exemplifies the latter—a turnkey field engagement measuring formation thermal conductivity over an 800-foot bore depth to inform HVAC system redesign, with all work performed on a compressed schedule and fixed-price basis. Universities and municipalities are the primary issuing bodies under this code, with research institutions focused on analytical equipment and municipalities focused on site-specific thermal characterization tied to sustainability and resilience planning.

Wisconsin and Mississippi represent the most recent activity, with the City of Madison issuing an IFB for the geothermal test bore-well (due August 24, 2026) and the University of Wisconsin-Madison and University of Southern Mississippi each soliciting thermal analysis systems and sensor upgrades (due July 17, 2026 and June 8, 2026, respectively). The Madison project requires contractor mobilization in September 2026 with final deliverables by December 2026, offering a concrete near-term opportunity for firms with geothermal drilling, borehole characterization, and thermal testing capabilities. The University of Southern Mississippi's sole-source procurement of a TPS Anisotropy Upgrade sensor software from CTherm Technology ($14,400 with academic discount) signals the specialized nature of this equipment market, where vendor lock-in and narrow technical compliance requirements shape procurement strategy.
