Labor Units for MC Cable Feeders

Our software doesn't have labor units for MC cable with anything larger than three #10's. I'm being asked to VE a project from pipe and wire feeders (3-500kcmil & 1-#3G, for example) to copper MC. Is there somewhere I can get good labor units for this installation? We don't use much of it here but it looks as though the AHJ is going to allow it.
 
My book for 3-350 Interlocked Armored Cu cable says .14/ft @6' .18/ft @10' ..21/ft @15' .25/ft 20'

The fittings are expensive and labor intensive

You also need to rent pulleys and shieves and rig them up prior to pulling

THEN there is the cost of the Interlocked Armored cable......it's very expensive

No way will it be cheaper than pipe/wire

The fittings are no longer expensive or labor intensive unless the MC is liquid tite. Arlington and Bridgeport both sell very reasonable fittings. Installation is generally not that difficult either. Unless the installation is over a large span that has a delicate "floor" like above already installed T-bar. Properly thinking things out will generally work. For example a small trapeze spaced 5-6 feet and you could actually set a regular tugger on one end with a rope across them and just pull. Typically you are working exposed. For that what we call Mini's also called conduit hanger with bolt work very well or a piece of strut to the ceiling and a one piece conduit strap. assemble to ceiling and just pop the mc in one strap at a time.

have you considered running parallel aluminum MC? Obviously this would be much less expensive and would break the pulls onto lighter more manageable chunks. Large MC has become very versatile and cost effective and can be obtained with the full size EGC required for parallel feeders.
