What A.D. Engineering does
A.D. Engineering (ADE) is a site civil engineering consulting firm founded in 2005 by Adam Driver and headquartered in Chattanooga, Tennessee. The firm provides professional engineering services to local development clients across southeastern Tennessee, with a service scope spanning planning, site layout, grading, stormwater design, water system design, sewer system design, and permit applications. ADE operated as a small practice (1-10 employees) anchored by a senior team that included Adam Driver, Donna Shepherd, Mike Hodges, Tiffany Farley, John West, and Wiatt Wehunt, serving as an integral part of the regional development community for nearly two decades. The firm's go-to-market was direct, relationship-driven sales to locally based developers, with no disclosed productization, software platform, or technology differentiation beyond standard civil engineering deliverables.
On August 1, 2024, A.D. Engineering was acquired by Kimley-Horn, a national planning and design consulting firm with nearly 9,000 employees across more than 135 offices. The combination brought ADE's local site civil engineering expertise into Kimley-Horn's South Regional operations, with Adam Driver continuing as President of the Chattanooga operations. The two firms had collaborated on prior projects for many years before the combination, which Kimley-Horn described as aligned with its strategic plan to invest in exceptional people and local markets. Following the acquisition, ADE no longer operates as an independent entity.

A.D. Engineering competitors and assessment
Company assessmentBroad incumbents
- AECOM: AECOM is one of the world's largest engineering and infrastructure consulting firms, offering site civil, water, environmental, and land development services that overlap with ADE's core practice area, though at global enterprise scale.
- Kimley-Horn: Kimley-Horn is A.D. Engineering's parent company following the August 2024 combination; it is one of the largest U.S. planning and design consulting firms (nearly 9,000 employees across 135+ offices). It overlaps directly with ADE in site civil engineering, planning, grading, stormwater, water, and sewer design, but at vastly larger scale and with national disciplinary breadth.
- HDR Inc. HDR is a large U.S. engineering, architecture, and consulting firm with site development, water resources, and transportation practices that overlap materially with ADE's site civil and water/sewer design services.
- WSP Global: WSP is a major global engineering consultancy with substantial site development, water, transportation, and environmental practices. It competes for the same types of development-driven civil engineering engagements that form ADE's book of work.
- Stantec: Stantec is a global engineering, architecture, and environmental consulting firm with extensive site development, water, and community development practices that overlap with ADE's offerings. It competes broadly for municipal and developer civil engineering work in the southeastern U.S.
Direct peers
- Barge Design Solutions: Barge Design Solutions is a Nashville-headquartered engineering, architecture, and surveying firm offering site civil engineering, planning, water resources, and land development services. As a mid-sized Tennessee engineering consultancy, it most closely mirrors ADE's model of regional site-civil and land development practice.
- KCI Technologies: KCI Technologies is a privately held, multi-discipline engineering firm with site/civil, transportation, water, and environmental practices. Its mid-size, employee-owned model and southeastern U.S. footprint make it a comparable peer for ADE.
- Mead & Hunt: Mead & Hunt is a mid-sized U.S. engineering and architectural firm with a strong site/civil, water, and land development practice across the Southeast. It is a credible peer for a regional site civil consultancy like ADE.
Regional players
- TranSystems: TranSystems is a consulting firm focused on transportation and infrastructure engineering with complementary site civil and water resources practices, serving similar public- and private-sector development clients.
- Gresham Smith: Gresham Smith is a Tennessee-based (Nashville HQ) planning, engineering, and design firm with strong southeastern U.S. presence. It offers site civil, land development, transportation, water, and environmental services that directly overlap with ADE's Chattanooga-focused practice, competing for many of the same developer clients regionally.
