    Default (Peoples gas) hbk engineering gas main hit

    Last week the new company called hbk just got there first high-profile hit. A contractor hit a 36" med. pressure gas main. Contractor states "the med pressure main was never marked out" but the locator told the contractor that this med pressure main was in his dig area. The W/P guy (hbk) came out and mark the main but never marked out the drip and the contractor hit that drip. My question is why did the W/P guy from hbk let the contractor dig that close to a main with the excavator to begin with?

    Excavators will do as they decide even if you have given them good information. I had marked three phase of electric primary in a parking lot. They were tearing up the parking lot, the buildings were in use and not being demolished, with a large track hoe. I went out front and told the job foreman that the lines read shallow and to hand dig around the marks. He go on the radio and told this directly to the track hoe operator. We were talking out front and ten minutes later we heard the fuses blow and the traffic signals go out. We went back to the track hoe and looked at the three primary cables torn up. Of course the operator said he did not think they were as shallow as he was told.

    Before that I had a ticket for a lot of digging at a school. I marked the area of the ticket and made a point to meet the excavator's foreman. I told him I marked the are of the ticket but outside the area of the ticket there was a second gas service and if he were going to dig further to call in an additional ticket. After I left he dug further than the area of the ticket and hit the second gas service.

    We can advise them or even try to command them but they will do as they choose regardless of us.

    I agree with PL . the answer to your question will be the same the rest of our lives. we mark and then they will cut and then they will damage . some excavators are lucky and then there are those that are unlucky . some are unlucky over and over . In the end, we ALL make mistakes. Life will go on as normal.....

    I've had utility operators themselves ask if I wanted them to "scrape down to" a line I was potholing for them. They think they're helping by using excavators within the tolerance zone. If it were me, I'd have made every effort to schedule a standby operation for this work, or to be on site (but I am certified to watchdog this line). Heck, I reach out to my customer if there is a MP line above 10" conflicting with the dig site, or sometimes even when smaller lines are in high affect areas (Schools, Hospitals, Public Buildings, etc). If there is an accessible drip, it gets it's own stake detailing as much.

    White it is easy to blame the locator, and a drip is a feature that generally should be designated, it was most likely within the tolerance zone of the marks laid for the 36" main... and you aren't ripping a drip out of a 36" steel main with hand tools, for sure.
