The U.S. Fish and Wildlife Service requires professional mold detection, remediation, and moisture mitigation services for Quarters #1 at the Culebra National Wildlife Refuge in Puerto Rico. The estimated construction budget is between $15,000 and $21,000, with a performance period of 90 calendar days from July 1, 2026, through September 29, 2026. This is a total small business set-aside that will result in a firm-fixed-price contract. Work must comply with federal, state, and industry standards for mold remediation and indoor environmental quality. A site visit is scheduled for June 10, 2026, and questions are due by June 12, 2026.
