About the Contract
The DiPSS contract is a Five-Year, Multiple-Award, Indefinite Delivery/Indefinite Quantity (MADIQ) Master Contract designed to provide logistical, life and mission support services, as well as operations and maintenance (O&M) at various U.S. Department of State installations worldwide, particularly in high-threat contingency environments. The scope covers a full range of services, including Life Support, Logistics (LSS&L), and O&M, to the Department of State and other U.S. government agencies under Chief of Mission Authority.
The Diplomatic Platform Support Services (DiPSS) Master Indefinite Delivery/Indefinite Quantity (IDIQ) contract provides comprehensive support services for U.S. Department of State and other U.S. government facilities worldwide, with a primary focus on high-threat contingency environments in the Middle East and South Central Asia. The contract enables the procurement of critical logistical and operational services, including life support, program management, facility maintenance, construction, renovation, and operational support across global government installations. Services encompass a wide range of critical infrastructure and mission-support functions designed to enable U.S. government operations in complex and challenging international environments.
Recent task orders demonstrate the vehicle's versatility, with contract values ranging from approximately $2 million to $179 million and covering diverse mission requirements such as vehicle maintenance, consulate decommissioning, returning detainee support, and Afghan relocation efforts. Advanced C4 Solutions Inc. (Ac4S) has emerged as a notable prime contractor, winning multiple task orders focused on logistics and operational support services. The task orders are primarily funded by civilian agencies within the State Department, such as the Bureau of Counterterrorism and Bureau of Near Eastern Affairs, and are predominantly awarded on a firm fixed-price or time and materials basis. While the original solicitation was set aside for small businesses, recent task orders have not maintained a specific small business set-aside designation, suggesting flexibility in contractor eligibility as the contract matures.
