    #8 THHN labor units

    Have about 80,000' that needs THHN pulled through existing parallel 2" emt conduits. Basically 100' horizontal and 40' vert. We usually use about 9 hours per M but I'm thinking this can be reduced a bit due to qty. and parallel sets. Any feedback would be appreciated. Thanks

    Are you pulling into conduit that already has conductors in it? If so, that's going to slow things down a bit.

    No empty conduits. Would really like to get feedback on this pull scenario. Thanks.

    Is 40' the total vertical amount, or is it 20' up, 20' down? Lift work or on the ground? Is that 80,000' of total cable or sq footage of the facility? Will splices need to be made up or can the pulls be done </= 4 quarter bends, or w/o j/pull boxes?

    Also, how are you paralleling #8 wire within Code?
    Electricians do it until it Hertz!

    I would not discount the hours at all.

    You are speculating there will be a savings, and it appears there will be.

    You would be guessing on how much to discount at this point. If you get the job, then you're planning with the forman/PM how to save.
    I would want to keep that savings for the reward of my good planning

    I wouldn't concern myself if some competitor labors the job by saying "4 men/6 days" or something.

    40' total vert. There will be one pull box in run, no splices. What code when your referring to paralleling?

    The original post referred to savings on labor for parallel runs. JFletcher thought that was a reference to electrically in parallel, not mechanically in parallel, i.e. same origin and destination.
    You cannot generally parallel smaller than 1/0 wires to get higher ampacity for the circuit.

    I think it is time for you to trust your own instincts. I have seen many of the questions you have asked and even a few private messages or the last couple of years. I am just not sure what your company structure is, what power you have to make decisions and whether you have people in your company to ask questions of. Remembering that the purpose of being in business is to make a profit, the price you should give is the price that is appropriate for ALL of the circumstances surrounding this issue. If it is a competitive bid the right amount is the amount that covers your overhead, and is JUST enough to be lower than the second competent bidder. If it is a negotiated customer that amount is again enough to cover overhead and reasonable profit. Usually higher than a low bid situation due to value added service, but not high enough to be taking advantage of the customer.

    All of that said, break it down. How much time to get the guys going. How long to set up a pull. How long to pull. How long to clean up. You are either going to be right or wrong.


    I know what I don't know, and I know where to go to find it!
