As we welcome new volunteers into the leadership industry. I believe that the American Shotcrete of ASA, I encourage each person to enter these roles with the Association is at a crossroads. Behind us stands primary goal of advancing ASA’s mission and to contribute to the legacy of a century of growth and setbacks, its growth. Recognition and credibility should be secondary innovation, and prestige in concrete construc- goals for all of us, although there can be no doubt that adding tion.

Some of these have been met. I’d people we reach, promoting awareness of the standards and like to use my first memo to call to action all sitting members science behind good shotcrete, and enhancing the reputability of the respective ASA committees to double their efforts to of our organization. meet the remaining objectives. The time is now. It is my privilege to call many of ASA’s members my personal friends. Those who know me also know that I am inspired by those titans of our industry who have chosen to take the high road—to never cut corners in mixture design or application, to submit their work to rigorous scrutiny, and to take seriously the obligation to uphold these principles when no one is watching. I would like to recognize past ASA Presidents and influential members who carried that torch: Pete Tatnall, Curt White, George Yoggy, Patrick Bridger, Rusty Morgan, Lars Balck, Larry Totten, Michael Cotter, and Chris Zynda, among others. It is my hope that every member of ASA understands the obligation to strive for excellence—an obligation that goes hand-in-hand with claiming the credibility of membership in the organization. Shotcrete has led me to some of the most exciting projects of my career—jobs that pushed the limits of engineering to breathtaking effect. As one of the most versatile construction methods available to us, shotcrete—done right—has the potential to carry new construction, infrastructure rehabilitation, and environmental engineering into the future. It is our job to ensure that we are there, too, with sound knowledge and excellent practices to help push the industry forward. I have every confidence that ASA will lead that advance with the help of its committed members. As part of this new generation, I am grateful for the efforts of my colleagues, among them Marcus von der Hofen, Marc Jolin, Scott Rand, Lihe John Zhang, Frank Townsend, Ezgi Yurdakul, Mason Guarino, Cathy Burkert, Randle Emmrich, and Marc Jolin. I look forward to doing my part to see that the Strategic Plan is implemented and our established goals for the next year are reached and surpassed. As this year’s President, I am honored for the opportunity to energetically represent ASA, to promote shotcrete as an advanced and sophisticated construction method, and to advocate for the highest standards in its execution. 2 Shotcrete • Spring 2016 Committee Chair Memo ASA Membership Committee By Tom Norman First and foremost, I would like to express across the industry.
