Summary
The notice states the Marine Corps Installations Command (MCICOM) Headquarters Contracting Office (Naval Support Facility Arlington, VA) intends to negotiate and award a sole‑source modification to the MCICOM Professional Services Support (PSS) IDIQ (reference PRO M9549425D5001-5003). This posting is a Notice of Intent / Special Notice (not a solicitation) intended to inform the public and to determine whether other responsible sources can meet the highly specialized requirement; it does not itself constitute a request for proposals. The presolicitation record indicates related solicitation materials (solicitation documents and access instructions) are provided via DoD portals (PIEE/eb) rather than as a public buyer-hosted PDF on the SAM.gov page, and no buyer-hosted solicitation PDF for this specific modification was located in the retrieved authoritative pages.
