Khristina Matthews-Sandoval

Khristina Matthews-Sandoval serves as a Contract Specialist within the W2SN Endist Japan office under the Department of the Army, responsible for managing the full lifecycle of construction and facility modernization contracts critical to sustaining U.S. military readiness in the Indo-Pacific region. She executes complex acquisitions for infrastructure projects including institutional buildings, housing, hangars, and maintenance facilities, ensuring compliance with FAR and DFARS regulations while aligning procurements with the Army’s strategic infrastructure priorities. Her role involves negotiating terms, evaluating technical proposals, and administering performance-based contracts to deliver mission-critical facilities that support Army and Air Force personnel and their families. Matthews-Sandoval maintains long-standing relationships with a core group of experienced contractors, including L1 Enterprises Incorporated, Gilbane Federal, Maeda-Samsung-KGC-Onaka Joint Venture, ICHIKEN CO LTD, and Toyo Construction Co., Ltd. These partnerships reflect a preference for established firms with proven expertise in military construction environments, particularly those with prior experience in Japan-based projects and familiarity with DoD standards. Her contracting approach emphasizes reliability, quality control, and schedule adherence, often leveraging task-order and indefinite-delivery/indefinite-quantity (IDIQ) mechanisms to respond efficiently to evolving facility needs. Her procurement portfolio reflects minimal use of socioeconomic set-asides, with 91.7% of awards issued under unrestricted competition and only 8.3% designated as Local Area Set-Asides under FAR 26.2. This pattern underscores a mission-driven focus on operational urgency and technical capability over socioeconomic preferences, though she remains compliant with all applicable small business regulations and actively considers qualified small businesses when they meet technical requirements. Matthews-Sandoval specializes in NAICS 236220 (Commercial and Institutional Building Construction) and 236118 (Residential Remodelers), with additional focus on 238110 (poured concrete structures) and 238220 (plumbing, heating, and air-conditioning systems). Her expertise lies in procuring integrated construction services for high-standards military facilities, requiring deep knowledge of military construction codes, environmental compliance, and facility sustainment requirements across austere and high-density operational environments.
