“I was doing this in and around Dallas Texas so I’m sure you’re correct about the depth along the east coast they can go as deep as they need to go , but I was familiar with work in Texas mostly shallow work.”
Well, howdy neighbor,
I’m in the Dallas area as well. Live in an unincorporated community up on the northern periphery of the metroplex. You’re probably right about that. Probably the biggest risk in Texas when tunneling is hitting old abandoned oil and gas wells.
Yeah hello, I live in East Texas now Longview.
No even back then there was a lot of infrastructure below ground.There was an engineering crew that their full-time job was going around and and identifying objects and obstacles and informing the crews so they wouldn’t hit hit anything. it was a major job.
