The U.S. Secret Service issued this RFI for market research to identify qualified construction management firms under NAICS 541330 that can support future construction, renovation, design-management, and related task-order work, potentially through a future BPA or IDIQ. The anticipated requirement is nationwide across Government-owned or leased facilities throughout the United States and its territories, including secure, occupied, operational, and time-sensitive environments. Work may span the full project lifecycle and include physical security enhancements, electronic security systems, infrastructure and building systems, and preventive or corrective maintenance. USSS seeks firms, including small and socioeconomic small businesses, with organizational capacity, technical expertise, security capability, geographic reach, bonding and staffing resources, and the ability to manage concurrent significant-value task orders and provide cleared personnel when required. Interested firms should submit a completed vendor questionnaire, a capability statement of no more than three pages, up to three relevant completed projects from the past three years, supporting documentation, and SAM.gov registration or applicable certification evidence electronically in searchable PDF.
