SAM, a leading provider of geospatial and surveying services, has acquired Donaldson Garrett and Associates, Inc., Land Surveyors (DGA), for an undisclosed amount. This corporate acquisition sees SAM buying the established surveying firm, known for its comprehensive land surveying and specialized services. Founded in 1991, DGA has built a reputation for quality and ethical practice, operating from offices in Macon, GA, and Charlotte, NC.

DGA offers a wide array of commercial professional land surveying services, including topographic, boundary, as-built, transmission line, pipeline, HAZMAT, and easement surveys. The firm also provides highly specialized services such as high definition construction stakeout, forensic litigation support, and precise optical tooling and laser alignment for industrial manufacturing equipment nationwide. Additionally, DGA conducts above and underground mine surveys, with MSHA Parts 46 & 48 trained personnel, and holds professional registration in 12 southeastern states.

This acquisition is a strategic move for SAM to expand its service capabilities and geographic footprint. DGA's deep expertise in niche areas like mine surveying, industrial alignment, and forensic support complements SAM's existing offerings, allowing for a broader and more specialized service portfolio. The integration of DGA's G-DOT prequalified status and its strong presence across the southeastern United States will enhance SAM's regional market penetration and client reach.

The transaction underscores SAM's commitment to growth through strategic corporate acquisitions, integrating DGA's established client base and specialized skill sets. The combined entity is expected to deliver enhanced value to clients by offering a more comprehensive suite of surveying and geospatial solutions. This move aims to strengthen SAM's position as a premier provider in the industry, capable of addressing complex project requirements across diverse sectors.
