Melinda Terry of the North Delta Water Agency, our source for the arresting numbers on pile driving and tunnel muck in our recent newsletter, reports that she had the wrong number for consecutive days of pile driving.
If there are about 1,000 piles total to be installed according to Appendix 3C in the BDCP Plan chapter 3, then 1,000 (total piles) ÷ 30 (avg # installed per day) = 33 days. In total there will be 1,000 X 700 = 700,000 pile driving strikes over 33 days.
OK, so that’s fewer strikes than originally estimated. Still, raise your hand if you want to be around while 700 strikes per day are delivered for weeks.
