Stockwell Engineers, Inc.

Stockwell Engineers, Inc., based in Sioux Falls, South Dakota, is a self-certified small disadvantaged business providing specialized cadastral boundary surveying, topographic and hydrographic mapping, aerial surveying, GIS support, and related architect-engineering services to federal agencies, overwhelmingly as a prime contractor (96% of awards) across multiple indefinite-delivery contracts and set-aside vehicles.

Stockwell competes predominantly under Total Small Business set-asides on its parent IDIQ vehicles. The company's recent prime portfolio splits between open full-and-open delivery orders issued against larger IDIQs and set-aside task orders. Substantive recent work includes a $3.4 million firm fixed-price delivery order from the Army Corps of Engineers Engineering and Support Center St. Louis for surveying services (award September 2025), a $4.57 million USAF Operations GIS support contract from ENDIST New Orleans running through May 2025, a $3.9 million architect-and-engineering survey and mapping delivery order from DISA St. Louis (August 2024) under Total Small Business set-aside, and a $317,344 hydrographic and topographic surveying delivery order for Missouri River survey work from USACE Omaha (April 2026) under Total Small Business. A $2 million USDA Forest Service Rocky Mountain Region cadastral boundary surveying IDIQ (September 2021) has recently spun off task orders; Stockwell also holds newer IDIQs from the Forest Service Northern Region ($5 million, September 2024, through September 2029) and the USDA NRCS ($3 million, March 2026, through March 2027).

Customer concentration is acute. The Army Corps of Engineers ecosystem dominates the award count and dollar volume: USACE Omaha District alone accounts for 25 awards ($57.3 million combined potential value), and the USDA Forest Service Rocky Mountain Region accounts for 7 awards ($22.2 million potential value). Together, these two customer families represent 73% of all awards and 85% of combined potential value. Within the Corps, the Omaha District IDIQ W9128F22D0029 (awarded January 31, 2022) carries a $45 million ceiling and has generated 14 task orders worth $16.6 million in combined potential value; this vehicle anchors most of Stockwell's prime work. The Kansas City District single-award IDIQ ($5 million, May 2026) and the St. Louis District IDIQs contribute additional steady-state task-order volume. The Forest Service and NRCS work focuses on cadastral surveying, boundary monumentation, and easement surveys on National Forests and Conservation Service lands across the Mountain West and Great Plains.

Activity has remained relatively flat year-over-year — 11 awards in 2022, 11 in 2023, 6 in 2024, 9 in 2025, and 7 in 2026. Five awards with combined potential value of $7 million face ultimate completion inside the next twenty-four months, presenting recompete exposure. The vendor's subcontract footprint is minimal: three recent subs under AECOM Technical Services and The Compass PTS JV for levee rehabilitation surveying and flood risk mapping hydrology work (March 2025 to December 2025) account for only 4% of the portfolio.

Stockwell holds a portfolio of five active prime IDIQs: the $45 million USACE Omaha District multiple-award vehicle (NAICS 541370, Surveying and Mapping Services), the $5 million USACE Kansas City District single-award IDIQ (May 2026, Total Small Business, NAICS 541370), the $3 million USDA NRCS single-award IDIQ for professional land surveying (March 2026, Total Small Business), the $5 million USDA Forest Service Northern Region single-award cadastral surveying IDIQ (September 2024, Total Small Business), and the $20 million USDA Forest Service Rocky Mountain Region multiple-award A&E cadastral boundary surveying IDIQ (September 2026, Total Small Business, five-state coverage in Colorado, Wyoming, South Dakota, Nebraska, and Kansas). Task orders issued under these vehicles run firm fixed-price with individual ceiling values typically capped at $500,000, though larger integrated delivery orders can exceed that threshold. The Omaha District IDIQ has been the primary production vehicle, supporting hydrographic surveys on the Missouri River, boundary surveys at military installations (Fort Carson, Buckley Air Force Base, Fort Leavenworth, Ellsworth Air Force Base), utility potholing at Minot Air Force Base, dam monitoring, and GIS support. USDA work centers on cadastral surveying at Black Hills National Forest and Nebraska National Forests and Grasslands through the Rocky Mountain Region IDIQ, and easement boundary surveys through the NRCS contracts.

Stockwell was registered in SAM.gov as a small disadvantaged business beginning in 2011, and maintains active certifications as a Subchapter S corporation. The company's capability statement emphasizes Professional Land Surveyor licensure in applicable states, PLSS (Public Land Survey System) retracement and resurvey expertise, photogrammetric mapping, LiDAR data collection, aerial photography, hydrographic and topographic analysis, CAD deliverables, and GIS data management — supporting military installation management, water resources infrastructure, forest management, and conservation easement programs. Recent work locations span the Midwest, Great Plains, and Mountain West regions, with primary performance in Sioux Falls, South Dakota.
