Incumbent Analysis (see Incumbents section for more detail)
This solicitation appears to have a closely related prior contract for the same Yellowstone National Park wastewater headworks scope, with Jacobs Government Services Company as the awardee on 140P2023D0006-140P2024F0438 (value $406,143; 09/18/24–09/30/25). The prior work is described as “Mammoth Temporary Wastewater Treatment Plant, Headworks Improvements Design Services,” which aligns with the current effort to construct the Mammoth Wastewater Treatment Plant headworks/supplemental headworks building. The design-focused improvements for the temporary headworks appear to be a continuation into implementation of the headworks upgrades at the Mammoth facility.
