ABC History



Building Minds. Building Skills. Building Futures.

Principle. Integrity. Strength. Quality. Just a few words that describe Associated Builders and Contractors, Inc. (ABC). Started modestly in 1950 by seven contractors in Baltimore, ABC has grown to a membership totaling 21,000 firms in 70 chapters throughout the U.S., proving that the pooling of resources continues to be a valuable approach to addressing common industry challenges.

ABC Keystone, the local Chapter established in 1959 and located in Rapho Business Park, Manheim, PA, covers a 10-county area in South Central Pennsylvania.

  • Promoting, protecting, and defending free enterprise in construction.
  • Promoting, protecting, and defending principled competition for our members.
