Prairie Engineers, P.C.

Prairie Engineers, P.C., an SBA-certified women-owned small business (WOSB) and 8(a) Program Participant based in Columbia, Illinois, delivers surveying, mapping, landscape architecture, forestry, and environmental services to the federal government predominantly as a prime contractor (97% of recent awards). The firm is a self-certified small disadvantaged business operating as a Subchapter S Corporation, with five named joint-venture subsidiaries (Prairie-Benham LLC, Whiskey Oscar Sierra Bravo JV, Prairie-Fgs JV, Prairie-Geo JV, and Prairie-Hanson 8A JV), each carrying women-owned and economically disadvantaged women-owned small business certifications.

Prairie Engineers' federal footprint centers on the U.S. Army Corps of Engineers, which accounts for 76 awards ($37.4 million combined potential value) representing approximately 82% of the prime portfolio. The top five customers by award count cover 96% of recent awards, but the top-value ranking is anchored by a single $50 million Blanket Purchase Agreement with the Department of Agriculture Forest Service (awarded March 2026 for the Land Management Integrated Resources National BPA, valid through March 2033). The Corps' three regional districts—St. Louis (57 awards, $8.3 million), Vicksburg (2 awards, $15.7 million), and Little Rock (2 awards, $5 million)—fragment the Corps' buying pattern, though all drive the same capability profile. The Department of the Air Force Air Mobility Command placed six awards ($3.6 million) for facility assessments and repairs at Scott Air Force Base.

Prairie Engineers' service portfolio spans hydrographic surveys (automated and manual), boundary and ALTA surveys, dredging support, tree planting and forestry management, environmental restoration and prairie reconstruction, geotechnical investigations, bridge inspections, and architectural and engineering design support. Recent representative work includes a $319,425 delivery order for a certified ALTA survey of a 6.59-mile railroad stretch at Military Ocean Terminal Sunny Point (February 2026, ENDIST St. Louis); a $650,114 delivery order for Black Creek Watershed RFP work (July 2024, ENDIST Vicksburg); a $628,057 8(a) sole-source award for Upper Mississippi River Restoration (September 2024, Corps); a $700,020 tree planting and forestry delivery order at Clarence Cannon National Wildlife Refuge (September 2023, Corps, under an 8(a) competitive set-aside); an $894,886 repair and construction contract for multi-systems and egress stair at Scott Air Force Base Building 1700 (May 2022, Air Mobility Command); and the $50 million USDA Forest Service LMIR BPA (March 2026) for nationwide project management, inspection, natural resources consulting, environmental restoration, and engineering support.

Prairie Engineers holds five active indefinite delivery vehicles, all with the Army Corps of Engineers. The $9.5 million RPO Tree Planting and Forestry IDIQ (Competitive 8(a) set-aside, through August 2028) has generated multiple delivery orders up to $700,000. The $5 million Architecture and Engineering Services IDC with Little Rock District (Competitive 8(a), through April 2028) has supported value engineering studies and A-E design work. A $7 million multiple-award hydrographic survey IDC and a $6 million surveying and measurement vehicle (Memphis Valley District) underpin recurring task orders for boundary surveys, hydrographic work, and dredging support. The three largest active IDCs—W912P921D0033 (52 task orders, $4.9 million), W912P916D0012 (31 task orders, $2.4 million), and W912P917D0022 (29 task orders, $4.1 million)—are all Army Corps of Engineers vehicles supporting design, surveying, and engineering work across districts. The newly awarded $15 million Architect-Engineer Surveying and Mapping Services IDC with ENDIST Vicksburg (total small business set-aside, through September 2030) extends Prairie Engineers' reach into the Vicksburg district's civil works portfolio.

Prairie Engineers' award concentration by NAICS reflects its core capability: Surveying and Mapping Services (93 awards), Landscaping Services (30 awards), Support Activities for Forestry (10 awards), Engineering Services (8 awards), and Architectural Services (7 awards). PSC codes align—87 awards under Architect and Engineering (Landscaping) and 27 under Natural Resources (Forest Tree Planting) PSC categories. Activity has remained stable at 14–21 awards per year over the past five years (2022–2026), with 2024 at 20 awards. However, sixteen awards (combined potential value $1.6 million) face ultimate completion in the next twenty-four months, posing modest recompete exposure; the $50 million USDA Forest Service BPA and the recently awarded $15 million Vicksburg IDIQ represent significant new capacity and multi-year security against immediate recompete risk. Across recent sub work, Prairie Engineers has delivered sonar-derived hydrographic surveying and topo surveys as a subcontractor to Dewberry Engineers, Stanley Consultants, and HDR Engineering on Corps and Air Force projects. Combined potential value across all 149 awards stands at $120.4 million, with $18.6 million obligated (15% utilization), signaling substantial unexercised capacity on parent vehicles and a sustained pipeline for federal civil works and environmental restoration missions.
