DiAnn Calderon Carty serves as a key procurement lead within Acquisitions - AQM Momentum (19AQMM) under the Department of State, where she oversees the acquisition of critical facilities support services essential to the safety and operational continuity of U.S. diplomatic missions worldwide. Her role centers on managing end-to-end contracting cycles for infrastructure maintenance, security systems integration, and technical services that sustain embassy and consulate operations abroad. She ensures compliance with federal acquisition regulations while aligning procurements with the agency’s strategic priorities in mission readiness, security modernization, and facility resilience. Her portfolio is exclusively focused on facilities support services, requiring deep expertise in lifecycle management of physical infrastructure and embedded security protocols. Carty maintains long-standing relationships with a select group of high-capacity contractors, including PBG Consulting, LLC, CGI Federal Inc., AMD International Technologies LLC, Pütz Security AG, and KADIAK LLC_DGI-ATI II LLC_Property & Environmental Management Inc. These partnerships reflect a preference for established firms with proven international capabilities in security engineering, facility operations, and technical services delivery. Her contracting patterns emphasize performance-based outcomes, task-order contracting under indefinite-delivery vehicles, and rigorous vendor performance evaluations to ensure mission-critical service levels are consistently met. There is no set-aside activity in her procurement portfolio; all awards are competed fully and openly under the unrestricted category. This reflects a strategic emphasis on leveraging broad market competition to secure the highest technical capability and global scalability, rather than socioeconomic set-asides. While small business participation is not formally prioritized in her award structure, all solicitations remain fully compliant with FAR requirements for fair and open competition. Her primary procurement focus is exclusively under NAICS 561210 (Facilities Support Services), encompassing integrated security operations, environmental management, facility maintenance, and technical support for diplomatic infrastructure. She specializes in procuring services that combine physical security, IT-enabled facility monitoring, and compliance with State Department security standards, requiring contractors to possess international operational experience and certification in force protection protocols.
