Solicitation Amendment for Wastewater Treatment Plant Preventive Maintenance Services for U. S. Embassy in Harare, Zimbabwe

The U.S. Department of State, specifically the U.S. Embassy in Harare, Zimbabwe, has issued a solicitation amendment for wastewater treatment plant preventive maintenance services. This Special Notice was posted on October 27, 2025, and represents a civilian agency contracting opportunity classified under NAICS code 562998 (All Other Miscellaneous Waste Management Services) and PSC code Z1ND (Maintenance of Sewage and Waste Facilities). The amendment modifies the existing solicitation number 19Z11526Q0003, with an effective date of October 17, 2025. The primary purpose of this amendment is administrative in nature, updating the contract documentation to include Defense Base Act (DBA) Insurance requirements in the pricing summary sections. This Special Notice alerts potential contractors to the modifications made to the original solicitation before submitting their proposals.

The amendment's key objective is to ensure that all pricing submissions reflect DBA Insurance costs in the updated pricing summary, which appears on pages 5-7 of the revised solicitation. The submission deadline for interested contractors is November 10, 2025. The underlying contract covers a base year plus four optional one-year periods, with two primary contract line items annually: wastewater treatment plant project management services and operator training, plant testing, technical analysis, and technical report development. While the Special Notice does not indicate a small business set-aside, it does not explicitly state eligibility restrictions, suggesting that qualified contractors meeting standard federal contracting requirements may participate. Contractors responding to this opportunity should carefully review the amendment pages 2-4 alongside the updated pricing summary to ensure compliance with the revised DBA Insurance requirements.
