Can't get a straight answer from dslreports.com so hoping maybe someone has some experience here and can help me with pricing.
I am giving a quote to replace aging telephone wiring. It's starting to rot (been in the rain to long) and needs to be replaced. I will be hanging 100ft of conduit around the building to run the wires through. What would you charge to run and hang the conduit 15 ft above ground? It will involve drilling a hole in the concrete, and then putting the clamp on with a concrete screw. It is PVC conduit and we will be using a ladder for access. |

If you can't figure the conduit quote out, I'd be questioning your capability to do the job. P&E is basic beginner stuff. Seriously though, do not use plastic conduit outside. Use EMT and either pull boxed or pre formed turns. You're gonna lose money on this since you've never done it. Either that or the customer accepts a grossly high bid. |

I've never ran wiring through conduit before so I don't know what an acceptable hourly/standard bid is. I do all of the IT work for this customer. I wired another one of her building phone systems but it ran through a basement, no need for the conduit. |

The price I quoted is for EMT conduit with die cast compression fittings and a couple weatherproof j-boxes. I never use PVC exposed. As an aside, electrical estimating is what I do for a living. I understand. They won't pay near that around here though. Thanks for your help, I will use EMT conduit instead of pvc. |

Pull up the website for the IBEW local in your area. They usually hate the wage rate sheets posted. That will give you an idea of the maximum labor cost for your area. Adjust accordingly, include your materials and a markup you are comfortable with. |
| It's a realy weird setup. The old lines go every which way around the building and they all eventualy end up in a 66 block.When Frontier & I was down there upgrading their dsl speed, he measured the noise margin and said the cables are all over the place, spliced into each other yadayada. The plan is to rip them out and install new new Cat5 plenum cables to carry 8 lines, even though they only have 5 lines there will be room for expansion. |

I'm not sure I would use PVC for a run that long outside suspended. You're going to get a lot of sag unless you double up on anchors. Do you think EMT conduit (metal) would be better perhaps? Absolutely. PVC unless made specifically for the task, is not UV resisitant. What are the walls composed of? If wood siding, conduit staples will suffice and the job will go quickly. Stucco would require clamps and take longer and be more expensive. |

Don't bother trying to string a pull string as you install the conduit. That may be okay for 20 feet or so, but at this length, get ahold of a fish tape. Just remember ells at corners or you're nowhere fast. Be a hero and pull 2 IWs. ETA Just read concrete. Tilt Up? Rent a powder actuated Ramset to drive the fastener in for the clamp. Practice a WHOLE lot to minimize spalling. You most likely need no more that a light .22 load. The older the building, the harder the wall. Beginning to understand VacaDuck's quote? |

Yeah, they use to have 8 phone lines but I talked with her yesterday and she said they will never have 8 phone lines again. Their only going to have 4 + the fax line and no more. We only have one corner thankfully. |

I have a hammer drill but its still going to be a long job. |

You don't say what size conduit????? A single phone line ......1/2" conduit or a phone cable?.........1 1/2"- 2" Personally I wouldn't use PVC but would go with rigid. Well anyhow I would charge between $15 to $maybe 25 per ft depending on size. 1/2" conduit |

You will need a conduit larger than 1/2" to take more than two cables. When we run conduit for data lines, we run 1" conduit for 2-3 CAT5. (job specs, cables could fit in a 3/4") |

Just saw your post. The reason I am running it through conduit is to last a lifetime. The old cables have been in the weather so long they are starting to rot. |

I didn't pick up on your location, EMT isn't allowed outside in some places so watch out for that, and don't forget about condensation and rain. eta If it's going to be visible it will look like rusted shit in a couple of years. I am in WV. It will be on the outside, thats why I wanted to use plastic so it don't rust. It's going to be under the eve of the building so I don't think it will be too exposed but its still out there. |

Vaca knows better, but I think you need a clamp every 4 feet. Thats a lot of drilling for anchors. with EMT you need a strap 3 feet from the box and every 10 feet there after. Also use mini's to keep the emt off the concrete. water can pool and ruin your pipe over time. and compression fittings. |

Op needs to maximize profit. Materials are the killer if he needs emt. Hell, multi million dollar bids are common place in the world I play in. It's not even serious money unless I need to talk to the boss, which is anything over 15 million. |
