Associated Builders and Contractors is a national construction industry trade association representing more than 21,000 members. Founded on the merit shop philosophy, ABC and its 68 chapters help members develop people, win work and deliver that work safely, ethically and profitably for the betterment of the communities in which ABC and its members work. ABC’s membership represents all specialties within the U.S. construction industry and is comprised primarily of firms that perform work in the industrial and commercial sectors.
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.
