United Consulting

What United Consulting does

United Consulting is a privately held, multidisciplinary engineering consulting firm founded in 1990 and headquartered in Norcross, Georgia. The firm delivers six integrated service lines — Geotechnical Engineering, Environmental Consulting, Construction Materials Testing (CMT), Special Inspections, Automated Instrumentation, and Building Enclosure Consulting and Testing — to public-sector agencies and commercial/industrial developers primarily across the Southeastern United States. Its underlying technology stack combines a 10,000-square-foot accredited testing laboratory (USACE, AASHTO, GDOT, and CAB of Georgia) with field-deployed automated instrumentation (robotic total stations, Shape Array Accelerometers, and remote sensors) and the Metafield reporting platform for integrated soil, concrete, masonry, and asphalt data. United Consulting is licensed in 27 states and operates 11 offices across Georgia, Alabama, Florida, Texas, and California, supported by a workforce of 101-250 employees under a founder-led management team (Reza Abree, P.E., CEO; with three founding members still active after 36 years).

The firm's go-to-market is direct professional services sales to enterprise and government clients, evidenced by a project portfolio spanning GDOT infrastructure, Hartsfield-Jackson Airport, the Atlanta BeltLine, Chick-fil-A, Murphy USA, Microsoft, Northside Hospital, and multiple healthcare and education systems. Pricing is not publicly disclosed and is structured as project-based, fee-for-service engagements scoped per client. Revenue mechanics depend on per-project consulting hours, laboratory testing volume, and instrumentation deployments; the firm has completed over 25,000 projects for 3,000+ clients since founding. Marketing is conducted through LinkedIn, Facebook, the monthly 'The Dirt' newsletter, and industry seminars, with brand equity reinforced by ACEC Georgia awards, APWA recognition, and 10+ years of top-25 Atlanta engineering firm rankings.
