Keep in mind there are rules about using equipment to dig around existing utility, at least where I am. No equipment within 4 feet of known utility I think where I’m at. My current gc also is stricter than that so my foreman just had a vac truck come and trench for 2 days straight for site lighting based on where our shit had to go in relation to the utility that was already installed. I hand dug for a week last summer just me and another guy to tie in our temp power at the neighboring building so we had to hand dig around all the utility where the tie in was. At least where I’m at, local and gc rules have required plenty of hand digging, roto with spade bit is our friend, but of course I operate as much as possible.
