John Liu

John Liu serves as a procurement professional within the Federal Protective Service East CCG Division 1 Acquisition Division, part of the Department of Homeland Security’s Office of Procurement Operations. He is responsible for managing the acquisition of protective security services and integrated surveillance systems critical to the safety of federal facilities. His work directly supports the agency’s mission to ensure operational continuity through the timely deployment of qualified personnel and advanced security technologies. Liu primarily handles service-based contracts under NAICS 561612, focusing on contract vehicles for security guard services, patrol operations, and related protective measures, ensuring compliance with federal acquisition regulations and performance-based outcomes. Liu maintains consistent working relationships with key contractors including GXC MAX INC, FLATTER, INC, and ENPROVERA CORP, all of which have demonstrated sustained performance in delivering security personnel and ancillary protective services. These partnerships are characterized by long-term contract execution, performance evaluations, and contract modifications to adapt to evolving facility security needs. His procurement approach emphasizes vendor reliability, compliance with security clearances, and adherence to performance metrics outlined in task order solicitations. Liu’s contracting portfolio reflects a strategic balance between open competition and small business participation, with 75% of acquisitions conducted without set-aside and 25% reserved for Total Small Business Set-Asides under FAR 19.5. While he does not routinely prioritize 8(a), HUBZone, or SDVOSB set-asides, his consistent use of small business set-asides demonstrates a deliberate commitment to fostering competition among qualified small entities in the security services sector. His technical expertise is narrowly focused on NAICS 561612, exclusively procuring security guard and patrol services for federal buildings and critical infrastructure. This specialization requires deep familiarity with DHS security protocols, access control integration, and workforce deployment standards, positioning him as a subject matter expert in physical security procurement within the federal domain.
