What Stockwell Engineers does
Stockwell Engineers, Inc. is a privately held, for-profit civil engineering firm founded in 1981 (originally Naughton Stockwell Engineers) and headquartered in downtown Sioux Falls, South Dakota, with a second office in Yankton. With an estimated 11–50 employees, the company delivers four integrated service lines under one roof: civil engineering (municipal infrastructure, street/highway design, water and wastewater treatment, drainage, flood plain mapping, land development), landscape architecture (parks, streetscapes, trails, urban design, sports complexes), land surveying (ALTA/NSPS, boundary, topographic, and specialized hydrographic/bathymetric and drone surveys), and EPC (engineering-procurement-construction) delivery for renewable energy digesters and industrial wastewater facilities. Its technical toolset includes AutoCAD Civil 3D, GPS/GNSS surveying, hydrographic sonar equipment, and drone-based aerial survey.
The firm serves a diversified base of public- and private-sector clients across nine named verticals: state and federal government (South Dakota Department of Veterans Affairs, USDA Forest Service, US Army Corps of Engineers), municipalities (Sioux Falls, Yankton, Brandon, Hartford, Harrisburg), education (University of South Dakota, University of Sioux Falls), healthcare (Sanford Health, Good Samaritan Society), agriculture/dairy (Boadwine Farms, Full Circle Dairy, Mill Valley Dairy), and industrial and renewable energy customers. Projects span at least ten states including South Dakota, Iowa, Minnesota, North Dakota, Montana, and Nebraska, though the operational core remains the Sioux Falls/Yankton region.
Revenue is generated through project-based professional-services fees that are custom-quoted by scope and complexity; no public pricing is disclosed. Go-to-market is sales-led and relationship-driven, with a proven record of contracting with government agencies for over 25 years, and delivery is fully direct with no resellers or intermediaries. EPC engagements add procurement margins and construction-management revenue on top of design fees.
