Goodwyn Mills Cawood

Goodwyn Mills Cawood, which trades as GMC, is an architecture and engineering firm headquartered in Montgomery, Alabama, with more than 20 offices across eight southeastern states. Its own materials describe a practice more than 75 years old. The firm combines architecture with civil, structural and transportation engineering, environmental services, surveying and landscape architecture, which lets it carry public projects from site planning through construction administration. Education and workforce facilities are a core market: GMC designed the $32 million Center for Welding and Automation Excellence that Greenville Technical College opened in Simpsonville, South Carolina in August 2026, a 44,000-square-foot building carrying 122 welding booths and 16 robotic welding stations. The Montgomery office alone employs more than 100 people.

Recent GMC work spans building types that rarely sit in one firm’s portfolio. Protective Stadium in Birmingham is an 835,000-square-foot venue built to hold up to 42,000 people for NCAA Division I football, professional soccer, concerts and other events. Montgomery Whitewater turned an Olympic-standard recirculating whitewater course into a downtown venue the city expects to draw roughly 300,000 visitors a year. Add Huntsville City Hall, the East and South Science Halls at UAB, Middle Tennessee State University’s Stephen and Denise Smith Student-Athlete Performance Center, Goodlettsville Elementary School, Jessie Davis Park in Douglasville, Georgia, and a $30 million emergency department expansion for MUSC Health.

That range comes from the discipline mix. Under one roof GMC provides architecture and interior design; site civil, water, transportation, geotechnical and mechanical, electrical and plumbing engineering; landscape architecture and planning; surveying; environmental services; GIS and permitting; coastal engineering tuned to waves, tides, sand and shoreline ecosystems; and a disaster recovery practice for communities rebuilding after storms.

Water is a substantial line on its own, covering treatment and distribution, wastewater treatment and conveyance, stormwater, water resources and ecological mitigation. It sits alongside aviation, roadway design and construction engineering and inspection under the transportation side of the practice.

The geographic footprint now stands at 27 offices across eight states. Alabama holds ten: Andalusia, Auburn, Birmingham, Daphne, Dothan, Eufaula, Huntsville, Mobile, Montgomery and Vernon. Florida adds Lutz, Orlando, Pensacola, Sarasota and Tampa. Georgia adds Atlanta, Augusta, Brunswick, Cartersville, Duluth and Savannah. South Carolina adds Charleston, Columbia, Conway, Greenville and Rock Hill, with further offices in Charlotte, Nashville and Brentwood, New Orleans, and Williamsburg, Kentucky.

The firm traces its founding to 1947 as an engineering practice, with architecture folded into the business in 1986 and landscape architecture, transportation engineering and environmental services added later. Corporate offices are at 2660 Eastchase Lane, Suite 200 in Montgomery, and project bids are routed through bids@gmcnetwork.com.
