Do you personally know the guys who will be doing this? Have they done the same type of install before? Might be good to check in with them if it's unknown then you're dependent on what kind of random 2 guys can do.
x4 though, right?
Yes.. but for my example just a TOTAL of 10-15 sticks whether it's one run or 4 runs.
Yes shop guys. How bout if we're talking about your guys who've done this before?
I know, waste of money. And it's for communications and it's concrete encased. Really stupid.
Then your numbers are fine. Guys who do this work all of the time will put in far more conduit per day than you're estimating for. The biggest obstacle versus PVC is the weight of RMC which is about 103 pounds per length.
Yea someone actually told me they could put in around 250’ a day…that 4 men on an7 hour shift . I found that to be quite a lot of 4” RGS in a trench in one day.
If you have a trench box the conduit has to be brought in from the end as the cross braces go across the bottom of the box.
No one I work with has done rigid underground that size after 2 inch they've gone parallel runs the costs just never have worked out. Again rigid underground is the odd guy out unless you're building a multi acre classified industrial superstructure.
25 sticks per person a day may be doable but is everyone 25 to 30 and build like an athlete who can do this for 3 weeks straight. They'll get more efficient but will also get warn out. With breaks that per person setting one every 15 min but you need two guys minimum so that's every 7.5 min one needs to go in and be threaded on.
