Wapsi Valley Archaeology, Inc.

Wapsi Valley Archaeology, Inc., headquartered in Anamosa, Iowa, provides Phase I and Phase II archaeological surveys, geomorphological studies, architectural documentation, Historic American Buildings Survey (HABS) and Historic American Landscapes Survey (HALS) work, and cultural resource management consulting to the U.S. Army Corps of Engineers as a prime contractor under a single-award Indefinite Delivery Contract. Wapsi Valley is a Department of Transportation-certified Disadvantaged Business Enterprise and a Subchapter S corporation that competes predominantly under small-business set-asides, with 100% of recent awards issued as prime contracts (no subcontract footprint).

The vendor's footprint is narrowly concentrated on USACE civil works programs in the Upper Mississippi River watershed across eight Midwestern states. Seventy-two awards in the source span from 2006 to May 2026, generating $21.4 million in combined potential value, of which $7.4 million (35%) has been obligated. The top customer by award count is the broader Department of the Army Corps of Engineers (48 awards, $9.2 million potential value), but the Engineering District St. Paul—a subordinate command—generates the highest dollar value (13 awards, $11.9 million combined potential). The Engineering District Rock Island (8 awards, $218 thousand) and the Department of the Interior Fish and Wildlife Service Region 3 (3 awards, $25 thousand) complete the active customer set; all four entities account for 100% of recent awards.

Wapsi Valley's work flows through two primary parent vehicles: an Indefinite Delivery Contract (W912ES22D0011) valued at $10 million, competitively awarded September 30, 2022, as a Total Small Business set-aside and extending through September 30, 2027, which has generated 37 task orders worth $6.5 million combined potential value, and an older Indefinite Delivery Contract (W912EK17D0001) with 27 task orders valued at $992 thousand. The newer IDC is the dominant vehicle; representative task orders include a $979,091.60 fixed-price delivery order for cultural services consulting during the planning and mitigation phase of the Fargo-Moorhead Metro Flood Diversion Project (awarded March 27, 2023), a $509,263.40 firm fixed-price delivery order for HABS and HALS documentation with unmanned aerial system overflight and Light Detection and Ranging capture supporting the same flood risk management initiative (awarded April 23, 2024), and a $1,882,404.29 delivery order for multidisciplinary cultural resource management services (awarded March 13, 2025). Smaller awards include Phase I archaeological surveys (ranging from roughly $13,272 to $90,513), geomorphological studies, historical property management plan development, and desktop literature assessments. All delivery orders use firm fixed-price structures without additional set-aside designations at order level, indicating Wapsi Valley competes across both set-aside and full-and-open task-order competitions under the parent IDC vehicle.

Activity has grown from 9 awards in 2022 to a peak of 16 in 2024, then declined to 6 in 2025 and 2 in 2026 year-to-date. Five awards with ultimate completion dates in the next twenty-four months carry combined potential value of $3.4 million, representing recompete exposure. NAICS coding reflects the core work: 69 awards fall under Research and Development in the Social Sciences and Humanities (NAICS 541711), with the remainder under All Other Professional, Scientific, and Technical Services. Primary Performance Specification Classification codes span Special Studies/Analysis for Environmental Assessments and Archaeological/Paleontological work, and Natural Resources/Conservation services. The vendor's geographic footprint of performance spans Moorhead, Minnesota; Fergus Falls, Minnesota; Kellogg, Minnesota; Knoxville, Iowa; Wever, Iowa; Mackinaw, Illinois; Anamosa, Iowa; Quincy, Illinois; Hull, Illinois; St. Paul, Minnesota; North River, North Dakota; Andalusia, Illinois; and Fountain City, Wisconsin—all anchored to Upper Mississippi River watershed civil works, habitat restoration, and flood control projects.
