Who We Are

Committed to Customer Satisfaction

Since 1975

Our story began in 1975 when Ed Davis and David Brown founded Davis Labs (now Davis & Brown), which offered services in waste treatment, engineering, and laboratory analysis for plants in the Florence area. It became clear early on that many of the plants we worked with needed significant repairs and upfit to continue operating efficiently, so in the early 1980s, we decided to combine our engineering and construction expertise and merge with North American Construction Company (NACC).

Today, all business units are consolidated under NACC. Davis & Brown is a wholly-owned subsidiary of NACC, and the two businesses are commonly referred to by their acronym: NACCDB. The company proudly provides construction, engineering, and environmental services in the Florence/Darlington area.
