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. Their courage and dedication to the merit shop philosophy spread rapidly, and within time, ABC became 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 U.S. construction industry. We look forward to welcoming each of you to our ABC family and to the Home of Merit Shop Excellence. Thank you for visiting.
