Chantal Rosales Cornelius

Chantal Rosales Cornelius serves as a Contract Specialist within the Public Buildings Service’s R4 (AMD) Acquisition Management Division, where she plays a pivotal role in executing complex construction and infrastructure support contracts for federal facilities. Her work directly supports the agency’s mission to deliver secure, efficient, and sustainable courthouses and office complexes through integrated design, construction, and maintenance services. She specializes in managing full lifecycle procurement actions—from solicitation and source selection to contract award and administration—focusing primarily on water supply and irrigation systems critical to federal building operations and environmental compliance. Her primary contractor relationship is with McKenzie Construction & Site Development LLC, a trusted vendor with deep expertise in site development and infrastructure integration for federal projects. Rosales Cornelius fosters collaborative, performance-based partnerships with this contractor, emphasizing compliance, schedule adherence, and quality control in the delivery of mission-critical utilities systems. Her procurement approach prioritizes transparency, risk mitigation, and long-term operational readiness, ensuring alignment with GSA standards and federal building codes. She maintains a steadfast commitment to socioeconomic diversity, directing 100% of her procurements to Women-Owned Small Businesses (WOSB), reflecting a deliberate strategy to expand opportunities for underrepresented entrepreneurs in the federal construction sector. This consistent focus on WOSB set-asides underscores her dedication to equitable contracting and the broader GSA mandate to promote small business participation in federal infrastructure development. Her technical domain centers on NAICS 221310—Water Supply and Irrigation Systems—where she procures specialized services including potable water line installation, stormwater management, irrigation infrastructure, and utility coordination for federal building sites. Her expertise lies in navigating the intersection of civil engineering requirements, environmental regulations, and federal facility standards, ensuring that all acquisitions meet stringent performance, safety, and sustainability benchmarks.
