Well, we finally got the permit on April 5th, and the PB started last Thursday on April 18th! In the first week, layout Thursday, dig done on Friday, steel completed by Tues, Inspection on Wed (and getting Verizon to re-run a cut fiber to the house from where the PB installed the post for the inspection sign!), and Shotcrete done on Thursday. Today, apparently was a day of rest.
Thanks to all who provided insight to help me make decisions in the design phase!
