The Pile Driving Contractors Association (PDCA) is an organization of pile driving contractors that advocates the increased use of driven piles for deep foundations and earth retention systems. To do this, we:

• Promote the use of driven pile solutions in all cases where they are effective.
• Support educational programs for engineers on the design and efficiency of driven piles and for contractors on improving installation procedures.
• Encourage and support research that will improve the reliability, usefulness, and cost effectiveness of driven piles.
• Give contractors a larger voice in establishing procedures and standards for the installation and design of driven piles.
