What AEC does
AEC, Inc. is a privately held, employee-owned civil engineering and landscape architecture firm headquartered at 50 Warm Springs Circle in Roswell, Georgia, with an additional North Atlanta office. Founded in 1990 by Charles H. McMillan III, the firm delivers integrated site design services spanning projects from under one acre to more than two thousand acres across the Southeastern United States, operating under professional licensure in ten states (Alabama, Florida, Georgia, Mississippi, Oklahoma, Pennsylvania, North Carolina, South Carolina, Texas, and Tennessee).
The firm operates as a professional services practice, organized around six service lines: Civil Engineering, Land Planning, Landscape Architecture, Arborist Services, Property Services, and Water Resources. Its delivery model combines master planning, site/civil engineering, landscape architecture, water resources (stormwater management, floodplain modeling, NPDES permitting, wetland mitigation), and arborist expertise within a single firm. Notable technical capabilities include LEED-certified and sustainable site design (e.g., the ASHRAE Headquarters LEED-EB Platinum project, UGA Veterinary Medical Center bioretention/wet pond/cistern system), and conventional tools such as AutoCAD, hydrology/hydraulics modeling, and GIS integration with municipal systems.
Revenue is generated on a project-by-project professional services basis through direct client engagement, with no publicly disclosed pricing. The go-to-market motion is sales-led and relationship-driven, targeting enterprise and institutional customers across five primary segments: commercial and residential developers, government and municipalities, healthcare facilities, educational institutions, and (to a lesser extent) energy and utility providers. Marquee clients include Costco Wholesale (multi-state warehouse rollouts including the 700th warehouse in Apex, NC), TopGolf, the University of Georgia, Health Management Associates, Verizon Wireless Amphitheater, the City of Roswell, and Orchards Communities. AEC has accumulated regional industry recognition including multiple ACEC Engineering Excellence Awards, AIA Honor Awards, and Atlanta Regional Commission awards between 2002 and 2016.

AEC competitors and assessment
Company assessmentDirect peers
- McAdams: Durham, NC-based civil engineering, land planning, and landscape architecture firm serving commercial, residential, and municipal clients across the Southeast. Directly comparable to AEC in integrated site design and licensing footprint, with a similar size and client mix.
- WithersRavenel: North Carolina-headquartered civil engineering and land development consultancy with practices in land planning, water resources, stormwater, and surveying. Comparable regional Southeast firm offering the same core civil/site services AEC provides to developers and municipalities.
- Halff Associates: Texas-based employee-owned engineering and architecture firm with civil engineering, landscape architecture, water resources, and land planning practices expanding across the South. Comparable to AEC as a mid-size, multi-discipline regional firm serving developers, municipalities, and institutions.
- SEPI Engineering & Construction: Employee-owned Southeast engineering firm headquartered in Raleigh, NC, providing civil/site design, transportation, environmental, and surveying services. Direct peer to AEC in ownership structure, regional focus, and core civil engineering practice serving developers and public clients.
- HGOR: Atlanta-based landscape architecture, urban design, and planning firm with significant mixed-use, commercial, and parks practice. Directly comparable to AEC's landscape architecture discipline, sharing Atlanta roots, Southeast client base, and similar award-winning project types.
- Thomas & Hutton: Savannah, GA-based multidisciplinary engineering and consulting firm with strong Southeast presence in civil/site design, landscape architecture, water resources, and land planning. Comparable mid-size regional competitor to AEC across overlapping service lines and Southeast geographies.
- Freese and Nichols:
Broad incumbents
- Stantec: Global engineering, architecture, and environmental consultancy with substantial site development, water resources, and landscape architecture practices in the Southeast. Competes with AEC for site design and municipal work, though as part of a much broader service portfolio across infrastructure, energy, and environment.
- Kimley-Horn: One of the largest US civil engineering and land development consultancies, with extensive site design, landscape architecture, and planning practices across the Southeast. Comparable to AEC as a multidisciplinary site engineering and planning firm, though far larger and offering broader transportation, environmental, and water services.
- KCI Technologies: Mid-Atlantic and Southeast engineering consultancy offering site/civil, transportation, environmental, and water resources services. Comparable to AEC in core civil engineering practice, though larger and broader in geographic and service scope.
