| COMMITTEE CHAIR MEMO ASA Contractor Qualification Committee I have been in the shotcrete business for over 50 years. I started as a laborer in the good old “gunite” days. Back then, there was no certification, or strict OSHA safety programs, but we did have a lot of beer to wash down the day’s dust. However, our crews had heart and worked as a team— nobody got hurt and quality was good. By Chris Zynda Success in the shotcrete industry takes HEART, hard work, and a commitment to quality. Over the last 50 years, I’ve seen a large increase in “stateof the-art” equipment, sophisticated mixture designs, and admixtures for the shotcrete process. Computerized batch plants are light years ahead of the plants from the late 1960s and 1970s. Concrete pumps designed for wet-mix shotcrete use have been redesigned for increased reliability and performance to accept the challenge for today’s fast-paced advancement of shotcrete more widely into the concrete construction industry. The official ACI Nozzleman Certification Program has been available for the last 17 years and has helped make acceptance of the shotcrete process much more widespread. This certification has helped, yet in some ways, it’s also hurt our industry. In my area of the country, I have heard many instances where small concrete pumpers think just having a pump qualifies them to shoot shotcrete. Some don’t have insurance or contractor’s licenses, have very limited knowledge of the details required for successful shotcreting, and lack accountability for the quality of their work. I’ve also heard of individuals who have an ACI Nozzleman Certification and view it as a license to work as a free agent for any contractor who has a concrete pump, though those contractors may have little personal experience or other crew members experienced in all the details required to successfully plan, coordinate, shoot, finish, and cure shotcrete. As one of the original ACI Committee C660 members charged with developing the ACI Nozzleman Certification Program, it was never our goal to have the ACI Nozzleman Certification Program even hint of going in this direction— where the only requirement for a quality shotcrete job is a certified nozzleman. The nozzleman is certainly an important part of the crew, but it takes the complete shotcrete team (owner, project manager, pump or gun operators, nozzleman, finishers) employed by an experienced contractor to consistently produce quality shotcreted projects. Our ASA Board of Direction Position Statement #1, “Shotcrete Contractor and Crew Qualifications,” provides further specifics (www. shotcrete.org/media/pdf/ASAPositionPaper_Board_1.pdf). In the spring of 2016, after much discussion, the ASA Board of Directors accepted the challenge to develop a Contractor Qualification Program (CQP) and created a standing committee—the Contractor Qualification Committee (CQC)—to both develop and administer the program. The ASA CQP is intended to be a straightforward 6 Shotcrete | Winter 2017 www.shotcrete.org
