Really? Ok...thanksA truck pulling a big trailer or a lawn tractor pulling a small trailer.
I haven't seen the site terrain. What are you thinking of using?Really? Ok...thanks
I'm really not sure. Haven't bid much of this type of work.I haven't seen the site terrain. What are you thinking of using?
A trailer can be unhitched while the truck does other things.
Can't bend 1-1/2 & 2" RGS by hand? Assuming not very easy at all and power bender much easier????I think that you'll some sort of flat bed truck or box with a rig to cut and thread the pipe and make bends. You'll need a generator on the truck to run the threader and bender, a pipe vise, and some sort of material storage for couplings, etc. A trailer would work but that depends on the terrain and trailers can be a nightmare to back up in close quarters.
You can use a manual Chicago style bender but for that much pipe you'll loose your shirt.Can't bend 1-1/2 & 2" RGS by hand? Assuming not very easy at all and power bender much easier????
Thanks so generally speaking that's about 1/2 hour of labor for a 10' length so 80' would take about 4 hours of labor( with 2 men).It seems to me that two can work easy and still add a stick every 15 minutes.
Unless I miss my mark, you are asking from an estimating perspective on this. If so, my two cents is STOP. You are putting WAY too much thought in to it. Use the labor standards established by your company. If you don't have GRC underground standards, then come up with a multiplier, probably about .6 and live with it.A few questions related to this.
1. THis job is a year long and all outdoors. I think it makes sense to account for "weather days" meaning the men start working and due to rain etc. have to wrap it up but get paid for full day. So I would account for "lost time" say 1/2 day lost per man/women for certain amount of days per month or look at hisotrical weather data and figure more or less based on month. Say April has more rain and Feb has more snow etc. Make sense??
2. So you think it's unreasonable for 2 electricians to be able to install 100' RGS in an 18" trench in a 7 hour workday? A straight run with no bends? Each end would end up in handhole where they would have to cut and thread only one end? Remeber they get lunch and there would be some setup and breakdown time so if I had ot guess the actual allotted time for install might be a 4-5 hour window? So 2 men 4-5vhours? Seem like they could get a lot more in.
I agree but thats what they want.Why does it have to be RMC? Is this underground? Why can't it be PVC with RMC 90's?
