So this is by far not only the biggest sewer replacement I've done but also by the absolute worst. So to start off I get a call and the guy told me his sewer had collapsed, he had 3 companies out there and they all tried to auger it and no luck, so he basically called around to see who could do it ASAP, and even though we are busier than a one legged man in an ass kicking contest we said we would start the next day. Did a locate to see where it was collapsed and we started digging. It was according to the locate right by the garage. Garage is two years old, I think you can see where I'm going with this. The sewer did an offset under the garage. We're sure that the guys who built a garage drilled a piling either beside or just above the sewer (damn lucky they didnt hit the water either)The ground is extremely unstable so we backfilled the hole, told him the situation and the price was going to change. Since the ground wasnt stable at all, we put shoring in an it was still collapsing on the walls we couldnt shore. Now we have to bore through the collapsed pipe with a special tool I've never used then do our trench less pipe replacement. We can't locate the sewer at the point of the property line so we basically were digging blind, not to mention there was no cc to be found, so couldn't even use that theory. luckily we found the exit point by the house and where it entered into the city sewer. Took us today and yesterday with all of the bull****. And to top it off it's no corrode pipe which is the pipe made of tar paper, total junk. Headed back Monday to get their new sewer line in. By far probably the worst case scenario. I'll throw some pics up Monday.
