Plans call for Underground MT Conduit?

[jschwarzenbach]

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.

MT = Empty

Agree. I'd still get it verified.
