ABC was founded in 1950 when seven contractors gathered in Baltimore, Md. to create an association based on the shared belief that construction projects should be awarded on merit to the most qualified and responsible low bidders. The courage and dedication of those seven contractors – Charles Mullan, C.K. Wells, Jr., Philip Cloves, Ernest Shultz, Edward Colwill, Charles Knott, and Edward Dickinson – helped to quickly spread the merit shop philosophy, within time making ABC the fastest growing association in the United States. Today, ABC is recognized as one of the leading organizations representing America’s business community and the merit shop construction industry.
