The U.S. Fish and Wildlife Service awarded a purchase order to S3 Solutions One LLC, a Service-Disabled Veteran-Owned Small Business, for janitorial services at Culebra National Wildlife Refuge in Puerto Rico on September 23, 2026, with a ceiling value of $159,965.00 under a Total Small Business set-aside. The order is firm-fixed-price and runs through September 30, 2031 with a base period of October 1, 2026 through September 30, 2027 and four optional one-year extensions. Performance takes place at Culebra, Puerto Rico, and comprises restroom sanitation, kitchen cleaning, floor care, window cleaning, waste management, and exterior maintenance across two zones (Administrative Building/Maintenance Shop and Quarters/Housing Unit). The contractor furnishes all labor, supervision, equipment, and EPA-compliant consumable materials. All contractor personnel require federal background clearance prior to work initiation. Performance standards mandate 95–100% compliance rates with zero tolerance for unreplenished restroom supplies during operating hours; non-compliance triggers mandatory re-performance within 24 hours at contractor expense and potential contract termination.
