Capt Justin Rainier

Capt Justin Rainier serves as a key procurement lead within the W7NU Uspfo Activity Ohang 121, part of the Department of the Army, where he oversees the acquisition of critical infrastructure projects essential to military operational readiness and force protection. His responsibilities include managing the full lifecycle of construction and facility modernization contracts, with a focus on commercial and institutional building construction, utilities, and site improvements. Rainier ensures compliance with federal acquisition regulations while aligning procurements with the agency’s strategic priorities in resilience, energy efficiency, and communications infrastructure upgrades. He plays a central role in translating mission needs into solicitation requirements and award decisions that support long-term installation sustainability. Rainier maintains collaborative relationships with a diverse pool of contractors specializing in military-grade construction and facility maintenance, particularly those with experience in Department of Defense environmental and security standards. While no single contractor dominates his portfolio, he consistently engages firms with proven expertise in government-funded infrastructure projects, including those certified under socioeconomic programs. His contracting approach emphasizes performance-based outcomes, rigorous oversight, and contractor accountability to ensure delivery of mission-critical facilities on schedule and within regulatory compliance. A strong advocate for small business participation, Rainier prioritizes Small Business Set-Asides under FAR 19.5, with approximately two-thirds of his acquisitions reserved for small businesses. This reflects a deliberate strategy to foster competition and expand opportunities for disadvantaged, HUBZone, and service-disabled veteran-owned firms. His contracting patterns demonstrate a consistent commitment to socioeconomic goals, ensuring that small businesses play a meaningful role in sustaining Army infrastructure. His primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), where he manages projects involving barracks, administrative facilities, and support structures. He also routinely procures services under NAICS 721110 (Hotels and Motels), primarily for transient lodging and billeting operations. Rainier’s technical expertise spans building codes, energy retrofits, and utility system upgrades, making him a specialized practitioner in military construction and institutional facility modernization.
