    I figure labor takes about 3x longer to install conduit overhead versus underground.

    Underground conduit goes from point a to point b as the crow flies generally, not always though. Overhead will usually have obstacles and need to follow building surfaces sometimes necessitating the use of pull boxes mid run.

    Come wire pull time, underground runs generally use less wire since they are usually straighter. That leads to faster pulls, because again, there are no extra pull boxes mid run that we need an extra person to watch or help feed wire into, etc.

    I do as much underground as possible on any given job.

    Running conduit overhead sometimes means running conduit at the tail end of the job when the construction schedule is even more compressed, I like having my underground finished at the start of the job before the job turns into a chinese fire drill.

    if you are pulling feeders, it's probably a little bit faster pulling into the ground.
    if you can set your spools up at the gear, the wire goes into the ground pretty
    effortlessly.

    the setups of spools tuggers and whatnot is where the labor is saved.

    a time honored tradition is that the electrician pulling the wire should be the
    one who ran the conduit. this way, if they were an idjit, it's a self inflicted wound
    trying to pull the wire.

    if you know what you are about, you can pull long feeders by yourself. it's not
    commonly done, but it's doable.

    longest i've ever pulled solo is 500 MCM aluminum simpull, underground, 700'.

    the trickiest deal is getting it started. i use maxxis tuggers to get the pulling head
    in the pipe, and then go to the other end, and use a targetcam to watch the pull
    while i'm pulling.

    off grid remote camera. 4 mile range. 6 hour battery life.
    can view up to six cameras at a time.

    the maxis triggers.... i won't pull wire without them.
    Very very helpful. Thanks

    The only way I know if a pull will be easy is if I ran the conduit. If I'm going to be pulling the wire the pull will be easy.
    I've heard that but why does it make a difference whether or not you have the person who ran the conduit install the wire? Thanks

    If the person who installs the conduit KNOWS he will be the person who pulls the wire, he tends to do a much better job installing the conduit so it's easier to pull.

    cause some people are dipsnits, and poor mechanics, and will put in stuff in a
    way that takes three times as long to pull as it should. if it can be pulled at all.

    you ran it, you pull it. oh, there two LB's, one in a corner, back to back,
    in the middle of a 350' run of two inch? and one is an LR,'cause you didn't have an LB?

    so you pull 190', and then get to an LR, and then pull it out and figure 8 about 200'
    of it on the ground, and then pull it in, so it all fits in the LR? and it's got soap on
    it, 'cause the purchasing agent saved $11 by not buying simpull?

    you pull it. have fun.

    The primary reason I run as much conduit under the slab is the total length of the up-coming wire pull.
    The drops from conduit installed from above are longer than the stub-ups out of the slab to a receptacle for example.
    I try to run as much as possible under the slab. No one cares if the PVC is running at angles, unlike exposed conduit runs.
