    Plans call for Underground MT Conduit?

    I am putting together an estimate and I am still fairly new to the industry. I have a set of plans with plenty of underground feeder that needs to be installed and most is in PVC, but one of my runs calls for 4" run of MT conduit. I can't find any reference to what exactly they're asking for, as far as I know MT conduit doesn't exist? Any ideas what they could be asking for?

    Probably EMT... though I would never bury it.

    Is it a US based design?

    Maybe this stuff? http://www.marshall-tufflex.com/mt-supertube

    I don't think it is found in the NEC

    That was my thought, EMT would just rust after a couple years.

    It is a US based design.

    I guess I will just put in an RFI.

    But why PVC everywhere else except that run? RFI for sure.

    I don't work construction, but I'm pretty sure they're asking for a spare conduit.

    Agree. I'd still get it verified.
