Project Management and Technical Oversight SupportThe contract is for Project Management and Technical Oversight Support under a subcontract arrangement, aimed at delivering technical and administrative assistance related to reporting, scheduling, and coordination efforts with the U.S. Army Corps of Engineers within an IDIQ task order framework. The work will focus on ensuring seamless alignment with USACE requirements through structured project oversight, data management, and timely communication channels. The North American Industry Classification System code 541611 indicates that the services fall under Management Consulting Services, suggesting a primary emphasis on advisory and operational support rather than direct construction or engineering execution. The contract was posted on June 17, 2026, and is administered by the W075 Endist San Francisco office under the Department of Defense, though specific performance locations, point of contact details, and set-aside classifications are not provided. There is no defined place of performance listed, indicating potential flexibility in where the work may be performed, possibly including remote or distributed operations. The absence of a solicitation number suggests this may be a follow-on or non-competitive subcontract under a broader existing agreement. The contract's structure implies ongoing support duties tied to multiple task orders, requiring adaptability, compliance with federal reporting standards, and consistent collaboration with a major federal agency.
