Della Ljungkull

Della Ljungkull serves as a Contract Specialist within the Public Buildings Service’s R5 Acquisition Management Division, where she plays a pivotal role in managing the acquisition of construction, renovation, and facility support services for federal buildings nationwide. Her responsibilities encompass the full lifecycle of contract execution—from solicitation and source selection to award administration and performance monitoring—ensuring compliance with FAR regulations and agency mission priorities. She specializes in procuring mission-critical infrastructure upgrades, including interior renovations, building systems modernization, and operational support services, aligning acquisitions with the GSA’s strategic goals for sustainable and efficient federal facilities. Ljungkull maintains consistent working relationships with key contractors, most notably MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, with whom she has developed a track record of successful project delivery. Her procurement approach emphasizes collaboration with experienced general contractors and specialized trade firms, fostering long-term partnerships built on performance reliability and regulatory adherence. She actively engages with vendors capable of delivering complex, multi-trade construction and facility services under tight federal compliance standards. Her contracting patterns reflect a strong commitment to small business participation, with nearly half of her awards structured as Total Small Business Set-Asides under FAR 19.5, complemented by a significant portion awarded through 8(a) competed procurements. This demonstrates a deliberate strategy to expand economic opportunity for disadvantaged businesses while maintaining competitive rigor in sourcing high-quality services. Ljungkull’s primary procurement focus centers on NAICS 236220 (Commercial and Institutional Building Construction), with substantial activity in plumbing, heating, and air-conditioning systems (238220) and other building equipment contracting (238290). She also routinely procures janitorial and landscaping services (561720 and 561730), reflecting a holistic approach to facility lifecycle management. Her technical expertise lies in integrated building systems procurement, where she ensures compliance with federal energy efficiency, accessibility, and sustainability mandates.
