Incumbent Analysis (see Incumbents section for more detail) The solicitation for HVAC upgrades at Mammoth Cave National Park shows a closely related prior contract, 140P5326P0011, awarded to Prosperity Partners Cr for $143,000 (05/18/26–10/22/26). The prior work is described as “MACA - RE-COMMISSION VC HVAC,” which appears to involve HVAC system commissioning/recommissioning activities at the same park and facility type, suggesting continuity in HVAC-related scope and familiarity with site conditions.
