Productivity in the Concrete Industry—Why Has it Stagnated and How Can ACI Help?

Productivity in the U.S. construction industry has been flat for 50 years, while productivity of U.S. industry in general has nearly doubled in that same time frame. Why? And what can ACI do about it? This session will explore answers to these and other questions and will include presentations from designers and contractors offering their perspectives on how ACI can help confront this very important industry issue. Moderated by Cary Kopczynski, with speakers Oscar Antommattei, Mike Schneider, Mario Garza, Mike Tholen, and Cary Kopczynski. Tuesday, March 30, 2021 (11:00 AM - 1:30 PM)
