Tiffany Chang

Tiffany Chang serves as a key procurement professional within the U.S. Army Engineer District Walla Walla, supporting the agency’s mission to deliver critical civil and military engineering solutions across the Pacific Northwest. She manages a diverse portfolio of acquisitions focused on infrastructure resilience, including the procurement of hydraulic systems, flood control components, and hydropower facility upgrades. Her work directly supports the design, maintenance, and modernization of dams, levees, locks, and associated water resource infrastructure, ensuring operational readiness and public safety through timely and compliant contracting practices. Chang maintains strong, ongoing relationships with a core group of specialized contractors including JR MERIT, INC., NORTHBANK CIVIL AND MARINE, INC., NORTH WIND GENERAL CONTRACTORS LLC, KNIGHT CONST. & SUPPLY, INC., and TRANSCO INDUSTRIES, INC. These vendors provide specialized engineering services, marine construction, and mechanical component supply tailored to complex water resource projects. Her contracting approach emphasizes long-term vendor collaboration, technical proficiency, and performance reliability, particularly for projects requiring precision in fluid systems, concrete structures, and civil marine works. A strong advocate for small business participation, Chang consistently prioritizes Total Small Business Set-Asides under FAR 19.5, with nearly 70% of her awards designated for small businesses. This reflects a deliberate strategy to foster local economic development and enhance competition among qualified contractors with demonstrated expertise in civil works and infrastructure support. Her contracting patterns show minimal use of other socioeconomic set-asides, indicating a focused reliance on broad small business eligibility rather than niche programs. Her procurement activity centers on NAICS categories including 335999 for electrical components, 326291 for rubber products used in mechanical seals and gaskets, and 333996 for fluid power pumps and motors—critical to dam gate controls and hydraulic systems. She also procures specialized machinery under 333998 and technical services under 541519, demonstrating deep domain expertise in mechanical, hydraulic, and digital systems supporting federal water infrastructure.
