Ying-Yen (Patricia) Chang

Ying-Yen (Patricia) Chang supports the Department of the Army’s 0413 Aq Hq Rco-hi in managing mission-critical procurement activities that sustain military readiness across the Pacific region. She oversees the acquisition of facility maintenance, logistics, and infrastructure-enabling services essential to installation sustainability and operational continuity. Her portfolio includes contracts for construction equipment leasing, environmental compliance support, and mission-critical community services, ensuring that Army installations maintain resilient energy systems, functional telecommunications, and compliant operational environments. Chang’s work directly enables the agency’s strategic priorities through timely, compliant, and mission-aligned contracting actions. Chang maintains consistent working relationships with a core group of contractors including HAMASAKI CONSTRUCTION LLC, PHOENIX V LLC, SURECAN LLC, HONOLULU DISPOSAL SERVICE, INC., and PERRY MANAGEMENT CORP OF SOUTH DAKOTA, L.L.C. These partnerships reflect a focus on regional vendors with proven capabilities in construction support, waste management, facility operations, and specialized logistics. Her contracting patterns indicate a preference for established, locally rooted vendors capable of delivering complex, multi-year services under tight operational timelines, often requiring coordination across military, civilian, and environmental stakeholders. Chang’s procurement strategy reflects a balanced approach to socioeconomic contracting, with approximately one-third of awards structured as Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to small business participation. While the majority of acquisitions remain open to all competitors, her consistent use of small business set-asides signals a strategic emphasis on fostering local economic resilience and expanding vendor diversity within the Pacific theater. Her primary procurement focus lies in NAICS 532412 (construction and mining equipment leasing), NAICS 624190 (individual and family services), and NAICS 813110 (religious organizations), indicating a unique blend of infrastructure support, social services, and community-based contracting. This reflects an integrated approach to sustaining both physical and social infrastructure on Army installations, requiring nuanced understanding of non-traditional defense service delivery models.
