Donna S. Hammock

Donna S. Hammock serves as a Contract Specialist within the W075 Endist Sacramento office under the Department of the Army, where she plays a pivotal role in executing acquisition strategies to sustain and modernize critical military infrastructure across the Western United States. She manages the full lifecycle of procurement actions for engineering services and heavy civil construction projects, ensuring alignment with Army installation readiness goals and environmental compliance standards. Her portfolio includes complex, mission-critical contracts for facility maintenance, land development, and infrastructure resilience initiatives, requiring rigorous adherence to FAR regulations and technical specifications. Hammock maintains consistent working relationships with a core group of experienced contractors, including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, DMZ BUILDERS, FAR WEST CONTRACTORS CORP, and ALEUT CONSTRUCTION LLC, all of which possess demonstrated expertise in military-grade construction and site development. These partnerships reflect a preference for contractors with proven performance in challenging terrain and regulated environments, often requiring specialized certifications and experience in federal construction standards. Her approach emphasizes reliability, past performance evaluation, and contract compliance over volume-based vendor selection. Her procurement patterns show a strong preference for open competition, with 62.5% of awards issued without set-asides, while actively supporting small business participation through 8(a) competed contracts (25%) and total small business set-asides under FAR 19.5 (12.5%). This balanced approach ensures market competitiveness while fulfilling statutory obligations to promote socioeconomic diversity in federal contracting. Hammock’s primary technical focus lies in NAICS 541330 (Engineering Services) and 237990 (Other Heavy and Civil Engineering Construction), reflecting her specialization in geotechnical, environmental, and infrastructure projects. She procures services such as site grading, drainage systems, erosion control, and facility upgrades that support Army base operations, demonstrating deep familiarity with military construction requirements and environmental remediation protocols.
