Anybody remember stories of substandard concrete from China, just earlier this year?
How long do you suppose it would take for that to show up in a spectacular way, if significant quantities of it has been used in the dam?
I’m betting less than 20 years, with minimal possibility that its detected in time to repair.
(This assumes no assist from a Taiwan firecracker.)
I don’t know about 20 years, but I expect, considering all of these stories about substandard construction, that sometime in my lifetime (I’m 22) that there will be a serious incident up there.
