Certification

There are two groups offering certification specifically related to post-tensioned concrete construction:

  • Post Tensioning Institute: PTI has certification programs for manufacturing plants and for individuals:

    • Manufacturing is certified for Unbonded Single Strand Tendon Fabrication Facilities (about 95% of U.S. production is certified under this program) and Prestressed Concrete Strand manufacturing (this is afairly new program--only 6 plants are certified, all in China).

    • Individuals must first be certified as Level 1 (fundamentals), then can go for Level 2 (either as an inspector or as an ironworker for bonded post tensioning installation). A new certification for slab-on-ground installer/stressor is in the planning stages.

    • More information on PTI certification programs.

  • Ironworkers Union: Developed by Jim Rogers at Evaluation and Certification Services (publishers of Post Tension Magazine), this program offers two programs, to certify installers of single strand unbonded post-tensioning installers and bonded post-tensioning installers. Rogers says they conducted over 2000 exams in 2007 and are ahead of that pace in 2008. Learn more about iron worker certification.
