    You left out a few details, like wall thickness for one. Fixed, or in a positioner / rollers?

    They won’t let you see the estimate? Have you ask?

    Default it is fixed pipe...

    its schedule .40 they are using it to tunnel under the beltway in VA. It doesnt move you lay on ground to get the bottom and work your way around. then they push it in 20' and add another piece.

    Schedule 40 has a wall thickness of .75. I assume stick on the root and wire after that?

    Between 5 hours and 3 days. Depending on the welders skills, fit-up and working conditions.

    If they're riding you just tell'em "I'll be done when I get done, and not a minute F***ing sooner"
    They'll either back off or fire you. A win-win either way.
