2019 ASA Outstanding Shotcrete Project Awards

The American Shotcrete Association (ASA) announced the recipients of its 2019 Outstanding Shotcrete Project Awards.

The recipients were honored at the 15th Annual ASA Awards Banquet held in conjunction with World of Concrete, Feb. 4 in Las Vegas, Nev. These awards confirm and demonstrate the exceptional advantages of shotcrete placement of concrete.

“We’re excited to showcase these outstanding 2019 winning projects. They exemplify how shotcrete placement creates high quality, durable concrete construction in a wide variety of applications. The projects demonstrate the inherent benefits of shotcrete, including enhanced sustainability, creativity, efficiency, strength and flexibility,” said Charles Hanskat, ASA Executive Director.

The winners were selected by an awards committee comprised of shotcrete professionals who dedicated their time and invaluable expertise, including Lars Balck, Cathy Burkert, Axel Nitschke, Ryan Poole, Scott Rand and John Zhang.
