Xuejiao Sun

Xuejiao Sun serves as the primary contracting professional for W071 Endist Seattle, a critical civil engineering and infrastructure unit within the Department of the Army. Responsible for managing the full lifecycle of construction and engineering acquisitions, Sun oversees contracts that sustain and modernize military installations across the Pacific Northwest. Their work directly supports the agency’s mission to enhance installation resilience through heavy civil engineering, environmental remediation, and hydraulic infrastructure projects. Sun handles complex, mission-critical procurements under FAR Part 36, with a focus on design-build, construction management, and integrated service contracts that require technical coordination across engineering, environmental, and facility operations disciplines. Sun maintains enduring relationships with a core group of specialized contractors, including RDC JPA Architecture, FinCantieri Marine Repair LLC, Walsh Federal LLC, Absher Construction Co., and Big River Construction Inc. These partnerships reflect a preference for firms with proven expertise in marine construction, heavy civil works, and specialty trade execution. The working relationship patterns emphasize long-term collaboration, performance-based outcomes, and compliance with stringent military construction standards, often involving joint site assessments and phased delivery models to ensure operational continuity. A strong commitment to small business participation defines Sun’s socioeconomic contracting strategy, with 75% of awards designated as Total Small Business Set-Asides under FAR 19.5. Women-Owned Small Business set-asides are also consistently prioritized, reflecting a deliberate effort to expand economic opportunity within the defense industrial base. The agency’s procurement approach minimizes no-set-aside awards, reinforcing a culture of inclusive contracting that aligns with Department of Defense socioeconomic goals. Sun’s technical focus centers on NAICS codes 237990 (Other Heavy and Civil Engineering Construction), 561730 (Landscaping Services), and 541380 (Testing Laboratories and Services), reflecting expertise in infrastructure resilience, site remediation, and environmental compliance. Procurements frequently involve erosion control, stormwater management, geotechnical testing, and nonhazardous waste disposal services, demonstrating deep domain knowledge in military installation sustainability and environmental stewardship.
