How’s this for a serious Throwback Thursday – more than 30 years ago, following the 1989 Loma Prieta earthquake, Interactive Resources, Inc. was enlisted on an emergency basis to evaluate the condition of Candlestick Park, which was hosting the third game of the World Series during the tremor. The City of San Francisco called on Interactive Resources, Inc. because the firm had provided structural engineering services for a massive five-year project in the 1980s to repair corrosion-damaged joints in the pre-cast concrete stadium. In 1989, Interactive Resources, Inc. simply knew the stadium construction better than anyone. We dispatched a response team of engineers and architects to perform a visual post-earthquake inspection and to perform immediate repairs. Ten days later, the World Series was able to resume at the stadium, repaired to its original condition. We recently found and converted a VHS tape of the news coverage of our investigation to digital, and for the first time in the era of social media can share this footage, including interviews with our founder and president Tom Butt and founder John Clinton (if you can’t wait, skip to 5:44 to see Tom!).
