Would someone be able to give me a ballpark number for wage rates for superintendant, Senior level fitter and helper for a sprinkler install in Wisconsin? Large industrial project, 30ft high roofs, a Standpipe, several wet systems, two dry systems. Not real complex.
Off forum would be preferred of course. I'm trying to verify an estimate and the wage rates seem a bit low. Craig L.

Pipe size is specified as a number and wall thickness as a schedule. The wall thicknesses were "Standard" weight, "extra-strong" and "double extra strong" this standard was established in 1927 by the American Standard Association. STD is identical to schedule 40 for NPS, XS is identical to schedule 80 for NPS and XXS wall is thicker than schedule 160. These designations of pipe strength are still in use today mostly in process plants. Make sure that what you are providing is what is specified by the EOR. I have seen where the plant specified standard weight pipe for sprinkler systems and the contractor went and installed schedule 10 pipe without waiting for plan approval by the plant's engineering team and the contractor had to remove all of the schedule 10 pipe and replace with schedule 40, the only good thing was the hydraulics worked for the schedule 40 also. Have a fire safe day.

American National Standard Weights and Dimensions of Welded and Seamless Wrought Steel Pipe ANSI/ASME B36.10M-1995. DoD guidelines required schedule 40 piping in many applications and require grooving to be cut, not rolled, something that cannot be done with schedule 10.

The EOR must be wanting to increase the robustness of the riser for some other reason. Hopefully he doesn't require threaded joints or there may be some guys looking for larger wrenches than they're used to using (and maybe some larger muscles than they have). While some might quibble that "standard weight" could now be argued to be Sch 10 for sprinkler mains and risers based on industry usage, I don't think they'd win an argument with the EOR that when he said standard weight, he meant Sch 40.

What is that supposed to mean? I've had more contractor confusion over that statement and I've been trying to find if there's a requirement for the riser to be Schedule 40 instead of allowing it to be Schedule 10 within the NFPA 13 Standard. So far I haven't found anything that dictates pipe weight for a riser. Anyone have any insight to offer? Craig L.
