Sheila Winston-Vincuilla

Sheila Winston-Vincuilla serves as District Contracting Chief for W2SD Endist New England under the Department of the Army, where she leads the acquisition strategy for critical infrastructure sustainment and modernization across New England. Responsible for managing complex construction, environmental remediation, and security systems contracts, she ensures alignment with Army installation readiness goals and federal procurement regulations. Her portfolio encompasses full lifecycle project support—from planning and design to construction and long-term facility maintenance—emphasizing resilient, compliant, and mission-critical outcomes. She oversees the full spectrum of contracting actions, including sealed bids, negotiated procurements, and task order management under indefinite-delivery vehicles. Sheila maintains consistent working relationships with key contractors including AGATE CONSTRUCTION COMPANY, INC., AGM MARINE CONTRACTORS INC, EDWARD PAIGE CORPORATION, ENVIROLOGICS INC, and JP SOLUTION LLC. These partnerships reflect a preference for firms with proven expertise in military-grade construction, hazardous material remediation, and integrated security systems. Her approach prioritizes performance-based contracting, with a focus on technical compliance, safety standards, and schedule reliability. She fosters collaborative vendor engagement through pre-solicitation outreach and post-award performance reviews to ensure mission success. Her procurement strategy reflects a balanced commitment to socioeconomic goals, with approximately one-third of her awards designated as Total Small Business Set-Asides under FAR 19.5, while the majority remain open to all competitors. She actively supports small business participation without relying on specific set-aside programs like 8(a), HUBZone, or SDVOSB, instead favoring broad small business eligibility to maximize competition and innovation. Sheila’s primary technical focus lies in NAICS 236220 (Commercial and Institutional Building Construction), 561621 (Security Systems Services), and 562910 (Remediation Services). She routinely procures services related to facility upgrades, perimeter security integration, groundwater and soil remediation, and utility system modernization—domains requiring deep regulatory knowledge of DoD environmental standards and construction safety codes. Her expertise ensures that acquisitions meet both operational readiness requirements and federal sustainability mandates.
