Associated Builders and Contractors (ABC) is a national association for merit shop construction and construction related firms. ABC represents 23,000 firms in 79 chapters. ABC is the contractor's voice in legal matters and helps to ensure that the most qualified lowest bidder may be awarded construction projects.

The Blue Book of Building and Construction is continually updated with information to bring buyers and sellers together. The Blue Book provides a central database to find information, request work, or place bids on the bid management system.
