TKDA is a 114-year-old, employee-owned civil engineering and architecture practice with ~300 staff across six regional offices. The tech stack is heavily weighted toward CAD and infrastructure modeling tools—AutoCAD Civil 3D, Revit, ArcGIS, and domain-specific hydraulics software (WaterCAD, HEC-RAS, SWMM)—reflecting a firm built around design-phase delivery rather than software-driven operations. Hiring remains minimal and senior-skewed, suggesting a mature, project-based labor model rather than scaling.
TKDA combines engineering, architecture, and planning services across industrial and manufacturing, transportation, building and sites, and water infrastructure markets. The firm operates six offices spanning the upper Midwest and West Coast, taking on work from municipal stormwater and wastewater systems to commercial and industrial site development. Project scope spans feasibility through construction administration—stormwater management, pump stations, utility infrastructure, wetland delineations, and treatment facility design. Active pain points center on contract acquisition (public and private), cost control on complex infrastructure work, and regional expansion, particularly in Milwaukee.
Primary stack includes AutoCAD Civil 3D, Revit, ArcGIS, and MicroStation for design delivery. Specialized hydraulics modeling via WaterCAD, HEC-RAS, SWMM, and traffic simulation tools (VISSIM, CORSIM) for infrastructure analysis.
Headquartered in Bloomington, Minnesota. Offices in Chicago, Duluth, Milwaukee, Minneapolis/St. Paul, San Bernardino, and Seattle serve clients nationally across industrial, transportation, water, and building sectors.
