SEG International is a 51–200-person civil engineering practice focused on sustainable site design across retail, residential, hospitality, and mixed-use sectors. The tech stack is dominated by Autodesk tools (Civil 3D, Revit, BIM 360, Navisworks) plus GIS and hydraulic modeling software—a mature, standards-based CAD workflow. Active projects center on BIM implementation and hydrologic modeling, but pain points around clash detection, QA/QC rigor, and automation suggest the firm is mid-transition from traditional CAD-centric delivery toward integrated digital workflows; leadership hires (Director of Engineering roles) indicate a push to formalize processes at scale.
Notable leadership hires: Director of Engineering, Engineering Director
SEG International was founded in 2009 as a sustainable civil engineering consultancy and has completed nearly 4,000 land development projects nationwide. The firm serves public, private, and government sectors across retail, fuel centers, fast food, residential, multifamily, mixed-use, hospitality, religious, office, and healthcare verticals. Core services span site selection, entitlement process management, hydrologic and hydraulic modeling, construction administration, and urban planning. The engineering-heavy headcount (12 of 17 active roles) reflects a project-delivery model; active work on BIM standards implementation and large-scale reorganizations suggests operational scaling.
Primary stack: AutoCAD Civil 3D, Revit, Autodesk BIM 360, Navisworks, GIS, ArcGIS, HEC-RAS, and MicroStation. HydroCAD and Smartsheet also in use.
