Sungate Design Group

What Sungate Design Group does

Sungate Design Group, P.A. is a privately-held civil and environmental engineering consulting firm headquartered in Raleigh, North Carolina, founded in 1991 and operating as a North Carolina professional corporation (License C-0890). The firm provides a full suite of water-resources and sustainable site-design services, including hydrologic and hydraulic modeling, stormwater management, sediment and erosion control design, environmental permitting, drainage and roadway design, bridge replacement hydraulics, stream restoration, and professional land surveying (boundary, ALTA, topographic, and subdivision surveys). Service delivery relies on industry-standard engineering software (HEC-RAS, HEC-HMS, HydroCAD, OpenRoads Designer, AutoCAD, Microstation, GEOPAK, ArcGIS, Carlson, Trimble) rather than proprietary technology products.

The firm's customer base is concentrated in North Carolina public-sector clients. It is NCDOT-prequalified across 14 work codes (hydraulic design, erosion control, roadway design, environmental permitting, stream mitigation, and others) and has completed more than 500 bridge replacement projects spanning all 14 NCDOT Divisions. It has served continuously as Town Engineer for the Town of Carrboro since 1995 and provides on-call consulting to the Town of Holly Springs since 1998, with additional municipal work for the City of Raleigh and Town of Wendell. Leadership consists of President Josh Dalton (owner since 2011) and Vice Presidents Brian Elam and Randy Howard, supported by a technical team of engineers, a CAD manager, a registered land surveyor, and an administrative manager.

The business model is professional services fee-for-engagement, with project-based contracts under NCDOT prequalification, multi-year municipal retainer and on-call agreements, and direct engagements with private landowners and developers for land surveying. The firm holds SPSF certification through North Carolina's Unified Certification Program, which provides access to small-business set-aside procurement vehicles. There are no disclosed software products, recurring SaaS or licensing revenue streams, or operations outside North Carolina, and no external institutional capital or M&A activity is reported.
