Non-competitive delivery order federal contracts represent a substantial segment of federal procurement, with total obligations approaching $38.8 billion across nearly 448,000 awards. The average award size of approximately $86,600 indicates a prevalence of mid-sized transactions rather than a few large contracts dominating the market. Historical trends reveal a marked increase in both award counts and total obligations starting in the late 1970s, suggesting a growing reliance on this contracting method over time. Agency concentration is notable, with the Department of State, Federal Acquisition Service, and Department of Veterans Affairs collectively accounting for a significant portion of obligations and awards, reflecting their operational scale and procurement needs. Vendor concentration is also evident, as a handful of contractors, including undisclosed domestic awardees and major defense and services firms like Lockheed Martin Services and Dyncorp, capture large shares of the obligated funds. For analysts, this data underscores the importance of monitoring agency-specific procurement patterns and vendor dependencies within non-competitive delivery orders. Contractors and procurement researchers should consider the implications of limited competition on market access and pricing dynamics, as well as the strategic positioning of dominant vendors. Overall, this page highlights the scale and concentration inherent in non-competitive delivery order contracting, providing a critical lens for evaluating federal procurement efficiency and market structure.
