How many actually order day to material( boxes, wire, conduit etc.) based of what was carried in the estimate?
So what are you referring to exactly ...conduit, cable and wire can't be ordered from estimate? Why not? Routings know at bid time different then after coordination in field is what I'm thinking .From a practical standpoint for the most part you cannot do it. You'll end up with an excess of some material and a shortage of other material. Fixtures, receptacles, plates, panels, transformers are a different story.
I'm not following you.I started each project with somewhere around 80-85% of the estimated.
Packages (Fixtures, Gear, Generators, etc...) were purchased per the estimate. Conduit, boxes, wire, miscellaneous.... I would start off buying in the neighborhood of 80% of what the estimate showed, this would allow me to put out quantities large enough to get good prices but not over buy as Rob points out.I'm not following you.
Because the amounts are never correct. Some things are under estimated other are over estimated. Left over material usually goes in the dumpster at the end of the job. If you ordered 85% upfront that might work out with little waste. You don't want to over order $20,000 worth of wire because that will go to the scrap yard.So what are you referring to exactly ...conduit, cable and wire can't be ordered from estimate? Why not?

Got it.Packages (Fixtures, Gear, Generators, etc...) were purchased per the estimate. Conduit, boxes, wire, miscellaneous....

On the last big project that I worked was a new building 62 stories loads of 750 kcmil feeders. This was the first time in my career that I saw the wire pull reels ordered from the estimate. Normally we pull in a True tape which measures the length of the run. Seems that the home office was worried that the foreman on some jobs were padding the wire orders. 20 extra feet on hundreds of runs and he's buying a winter house in the Boca. So anyway they decided that the PM's would order all of the large wire. Well in came the wire and when many of the pulls were done there was 75', 80', 100' extra due to field conditions. Some ended up being short. Didn't work out the way they planned.Got it.
