Det. Approving Consolidation of CT Req - CI Mosquito and Herbicide Treatment, 02032026_Redacted.pdf

This is a Consolidation of Contract Requirements Determination document for Craney Island Mosquito and Herbicide Treatment services in Portsmouth, Virginia, issued by the U.S. Army Corps of Engineers–Norfolk (NAO) in June 2022.

NAO proposes to consolidate two previously separate requirements—aerial mosquito treatment and aerial herbicide treatment at the Craney Island Dredged Material Management Area—into a single contract. The mosquito treatment involves applying Bacillus thuringiensis (Bti) granular and liquid larvicide and Undiluted Naled (Trumpet EC) across approximately 600 acres per treatment occurrence, with up to 18,400 acres treatable annually. The herbicide treatment consists of a single annual application of Habitat herbicide at 6 pints per acre covering 250 to 750 acres between September 1 and November 30. The contract period includes a base year with four option years, with a total estimated value of $17.5 million under NAICS code 561710 (Exterminating and Pest Control Services). NAO intends to award a single contract via Simplified Acquisition Procedures (SAP) under FAR Part 13, with 100 percent set-aside for small business, due to time-sensitive performance requirements and relatively simple technical specifications. The procurement history shows seven of nine past acquisitions were awarded to Eastern Aviation, LLC (formerly Crabbe Aviation, LLC), with minimal competition. The Consolidation Benefit Analysis demonstrates that consolidation saves approximately $50,000 in acquisition and administration costs while providing increased quality and efficiency through unified contractor coordination. The document concludes that consolidation is both necessary and justified and will serve the Government's best interests while providing maximum practicable participation by small business.
