About the company
Foth Infrastructure & Environment, LLC, a De Pere, Wisconsin-based professional consulting firm, operates as a prime contractor providing expert witness services and litigation consulting to the Department of Justice on a full-and-open basis, with no small business set-aside designation across its federal portfolio. The company is structured as a limited liability partnership competing in the open market for specialized legal and environmental consulting support.
Foth's federal work concentrates narrowly on DOJ litigation and expert services. The vendor's nine recent prime awards total $1.5 million across combined potential and obligated value, with 100% of work classified under NAICS 541713 (All Other Legal Services) and PSC code support for expert witness and environmental assessment work. The top three customer agencies — the Department of Justice's Environment and Natural Resources Division (6 awards, $1.4 million combined potential value), the DOJ Civil Division (2 awards, $38 thousand), and the Army Installation Management Command Southwest Region (1 award, $24 thousand) — represent the entirety of the portfolio. The Environment and Natural Resources Division anchors 93% of combined potential value, establishing strong customer concentration around DOJ environmental litigation work.
Recent representative awards include a $583,334 purchase order from the DOJ Environment and Natural Resources Division for expert witness services under time and materials pricing, awarded August 20, 2026 and running through February 1, 2031; a $19,878.90 litigation consulting purchase order from the DOJ Civil Division awarded January 27, 2025 with ultimate completion December 26, 2025; and a $18,243.50 litigation consulting purchase order from the DOJ Civil Division awarded May 2, 2025 with ultimate completion January 7, 2026. All work is performed in De Pere, Wisconsin. The vendor carries no parent contract vehicles, does not sit on GWACs or agency-wide IDIQs, and generates no subcontract footprint — the nine awards are entirely prime work with no sub-awards recorded in the source data.
Activity is sparse and episodic. The vendor received three awards in 2012 (the earliest in the data), one in 2016, two in 2020, two in 2025, and one in 2026, with no meaningful growth trajectory over the past decade. Of the nine awards, only two remain active beyond 2025; the remainder are either completed or completing within months of the current date. Recompete exposure is minimal given the small award volume and the concentration of value in the single $583,334 expert witness engagement extending to February 2031.
