"A 50-year-old person isn't as robust as a 16-year-old," Bob Bea, a professor emeritus of civil engineering at UC Berkeley, told the Bay Area News Group. "And neither is a 50-year-old dam. Most of our infrastructure dates back to this time period. It's now in its old age - the geriatrics phase - and we are still using a reactive approach to manage these systems. We wait until we have a big problem. It is much more cost-effective and safe to be proactive than waiting to fix something after an infrastructure disaster."
"I have not heard or read about any significant deliberations of the major risks that face our country today and tomorrow. Sad for the U.S.," said Bob Bea , a University of California Berkeley engineering professor who is a long-time expert in human-caused disasters.
