William B. Zucconi

William B. Zucconi, a sole proprietor based in Madison, Connecticut, provides expert witness testimony and litigative case support services to the Department of Justice's Civil Division as a full-and-open prime contractor with no small business set-aside designation. Zucconi operates without subcontractors, performing all work directly.

Zucconi's entire federal footprint concentrates with a single customer agency — the DOJ Civil Division accounts for all 21 awards and 100% of combined potential value ($275 thousand). The vendor has maintained a sustained relationship with the Civil Division since October 2021, securing purchase orders on a repeated basis for expert witness services across complex federal litigation. Recent representative awards include a $14,991 purchase order issued February 18, 2026 for expert witness and litigative case support (ultimate completion February 17, 2029); a $14,991 purchase order issued January 21, 2026 (ultimate completion January 20, 2029); and a $31,866 purchase order issued September 26, 2023 for expert witness services (ultimate completion September 30, 2026). Individual award ceilings have ranged from $2,725 to $35,791, with most falling in the $13,000 to $16,000 range. All awards carry time-and-materials contract structure and two-to-three-year performance periods, reflecting the ongoing nature of the Civil Division's litigation docket.

Activity has remained relatively stable. The vendor received five awards in 2022 and five in 2023, two in 2024, four in 2025, and two in the first quarter of 2026. Seven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $138 thousand, representing approximately 50% of Zucconi's total potential-value exposure and therefore a significant recompete risk window. The vendor does not appear on any named IDIQs, GWACs, or BPAs — all awards are direct purchase orders from the Civil Division itself.
