  • Interesting Job

    I have a friend who is an Electrical Contractor. We have worked together for over 30-years on different projects. About 10-years ago I got him stated work as an Expert in Construction Litigation as well. He called me today and asked me to help him with one of his cases.

    This is a project which includes a couple of 200' feeds which are in 4 conduits. This is a new project and there is already a problem before the job has been completed. For whatever reason he is pulling all of the wire back out of the conduit.

    The problem is one of the fittings pulled apart and he noticed the conduit was not fully inserted into the fitting and the conduit had large sharp edges which had not been reamed. Anyways now he wants me to send my seesnake through the rest of the conduits to inspect the rest of the fittings.

    I never thought of using my seesnake in that way but I guess it will work. I just hope the non reamed joints will not hurt my push rod.

      mark, you think that is bad, try running into 4'' sheet metal for a dryer vent.

      you'll be ok as the electrical fittings have a long sweep and the push will be much easier than plumbing lines. is this emt or ridgid.

      the transmitter will have a difficult time penetrating the steel pipe. 512hz. works great on cast iron, not steel. keep track of your footage and changes of direction to help locate.

      ps. if you need a helping hand, i can bring out one of my older, on the shelf cameras

      will work for food

        Okay last night I ran a KD-200 mini camera through the 4” conduits. This project is at a High School so we could not start the work until after 4:00 P.M. and we finished just before midnight. The guy who hired me had also hired an Electrical Contractor to pull all of the wires out of the conduit before I ran the camera through it.

        I believe what started the problem I was looking at is one of the runs which is under the raised floor pulled apart and it was noted the EMT had sharp edges from cutting the conduit. Each run was 200’ long but I had pull boxes at 110’ and 170’. I found the limit of the push rod to be right around 100’ and a couple of sweeps. As such I had to run the 110’ run through both ends to get a complete picture of what was going on.

        An inspection of the inside of the conduit revealed in many cases the EMT was not fully inserted into the fitting. In addition many of the EMT ends were bent, had sharp edges or were covered in dirt. In some cases the EMT was as much as 3” from being seated against the shoulder in the fitting. You could actually see the lock screw only caught the conduit by the very edge of the conduit which left a large bend in the end of the conduit. Along with the dirt in the conduit I noted rocks, rusty nails, a broken compression ring and half of a clothes pin.

        All in all the camera did a good job of inspecting the inside of the conduit. When the limit of the push rod was reached I wished it had been a lateral so I could have just flushed the water closet to get that last 10’.

            Rick,

            The Project Manager and State Inspector watched me the entire time. They were really impressed with the results so I might get a lot more work out of them. I believe this is just one building in one school out of 20-schools they are working on.

              You'll get more work and the electrical contractor will get a lot less work. LOL

                The update is they now want me to video after the new stuff is installed to show the old contractor what his job should have looked like.

                      Rather than a training video this will be used to show the other Contractors Insurance Company how he should have done it. With prevailing wages you’d think this stuff should not happen.

                        mark, i saw electrical ,emt fittings with an inspection hole in the fitting at the joint. this was on a large fitting (1.5''). sort of like some of the sprinkler rod couplings we use. this way an inspector or installer could have caught this without all the rework.

                          So you will end up unintentionally instucting them how to perform the work correctly, an ad-hoc training session more or less.

                            i had an interesting job these last few days. there was aburied 2'' pvc 200 amp 3 phase conduit that blew out a few days ago. the line ran from an electrical main panel 180' away in another building, underground to feed the panel in a movie production co.

                            with all the hot weather we've had these last 2 weeks, the temporary power cords to bypass the underground was not going to handle the air conditioning demands.

                            the contractor hired me on day 2 to locate the buried conduit and problem area. i ran my color mini seesnake and within 1 foot the lens got smeared with cable lube. at this point all i could do is push and feel. at 40' i felt a little resistance. i marked the line just outside the building at 1'9'' deep. i continued to locate at 50'. 9'' deep and 60' 9'' deep.

                            the next day they called me back as they attempted to swab the line clean and lost the rag that was tied onto the pull rope. this time the line was clean enough to see the real issue. at 40' there was the scortched pipe. i then located the rag at 103' in and at 23' in from the other side. still a 3' spread between the 2 marks. both 9'' deep.

                            today, the third day i used my 7/8'' k-60 machine to retrieve the rag out of the pipe. i then jetted the line with 3000# 5.6 gpm jetter to wash out the pvc. removed lots of cement slurry that had formed around the old wire. appears that the pvc was broken at the 40' and then the pipe was buried in concrete to protect the shallow depth.slurry got in along with ground water. 20 years later the wires shorted out.


                            still getting hung up at the 103' mark where the rag was, i videoed the line from the 23' direction and located a 1/2'' pvc sprinkler pipe had penetrated the top of the conduit. along with more cement slurry.

                            so after 3 trips and 4 hours of work, the problem is solved and conduit is repaired. the electricians come tomorrow to repull the 4 wire feed into nice clean pvc conduit.

                            without the camera, jetter and snake, the power would still be out and the contractor would be digging up the concrete to replace the entire underground. this was all fixed with less than 10' of conduit.

                              how about the sewer line that was pierced by a core sample drilling rig?

                              i was called to a small medical complex last week to figure out why the sewer is plugged up and the last plumber had to cut off his snake.

                              i ran my seesnake out 74' into the stopped up line. trying to get a strong signal, i backed it up to 25' to start tracking it. yipes th eline is already 7'6'' deep. after marking every 10' i got to the dead end at 74'. i moved a parked truck that was where my camera homed in on.

                              guess what? under the truck was some fresh asphalt (6 months). it was a soil core sample done in 2 spots of a 50 spot parking lot. at 8' deep the sewer was hit by a 6'' diameter core.

                              after discussing my findings with the dr. in charge, i was informed that the sewer had backed up 4 hours after the cores were drilled. this was 6 monts ago. it has been backing up every 2 weeks since. you would have thought that the dr. would have put 2 and 2 together

                              once the problem was discovered the blacktop was hand dug by another co. in 3 hours. half the dirt had already washed down the sewer at this time. 2 cleanots were installed and the line was jetted to wash out the remainding debris.

                              the seesnake allowed me to find the problem, even thought the pipe was full of sewage. too bad the dr. didn't use some common sence prior to snaking the line for 6 months.

                              rick.
