What SEH does
SEH (Short Elliott Hendrickson Inc.) is a 100% employee-owned multidisciplinary professional services firm founded in 1927 and headquartered in St. Paul, Minnesota. The firm employs more than 900 engineers, architects, planners, scientists, and technical professionals delivering infrastructure, transportation, water, environmental, and building-related services to public and private sector clients across the United States and several Canadian provinces. Its service portfolio spans the full project lifecycle — from planning and funding advisory (including its branded FundStart service) through engineering design, architecture, environmental compliance, construction administration, and asset management — across more than 35 discrete service lines covering highways, bridges, airports, water/wastewater, rail, land development, GIS, drone surveying, and trenchless technology.
The firm operates a horizontal professional services platform organized around client segments: state departments of transportation (MnDOT, WisDOT), municipal and county governments, federal agencies (notably the U.S. Army Corps of Engineers), institutional/nonprofit clients, and private developers. Revenue is generated through project-based, fee-for-service contracts priced individually by scope, complexity, and duration, typically awarded through qualifications-based selection and public sector procurement. Work is delivered through a combination of in-house staff and joint ventures (e.g., Himalayan Consultants JV, Parsons, Barr, and the SEH Design|Build subsidiary), with the firm also operating a related engineering subsidiary, RAM Companies.
Customer relationships are anchored in long-tenured public-sector engagements — the Twin Ports Interchange (MnDOT), Coulee Region Transportation Study (WisDOT), and Upper Mississippi River Restoration (USACE St. Paul District) all signal multi-year, high-visibility anchor projects. In 2026, the firm formalized an enterprise AI strategy by appointing a Director of AI and expanded its Florida footprint with a new Panama City office targeting the Northwest Florida market. Its employee-owned ESOP structure, 98-year operating history, and ACEC/ASCE/WTS industry recognition in 2026 collectively characterize a mature, relationship-driven infrastructure services platform.
