Pipe installation man hours issues.
Pipe installation man hours issues.
(OP)
I have posted 2 attachements below. One from estimators piping man hours manual 5th addition and another from a contractor who priced some work for us.
The contactor got a value for a straight pipe run handling and erecting of 0.72 man hours per meter for a DN200 pipe. They also claim this came from the Estimators Piping Manhours Manual edition 3.
So we used the attached which a snap shot from Estimators Piping Manhours Manual edition.
For an 8 inch pipe they have 0.48 Man hours per foot. So if there is 3.28 feet in a meter then this will be 0.48 x 3.28 = 1.57 man hours per meter. This is double compared to the contractor who priced the work.
I hope I am doing something very stupid here as it is really a problem. The actual pipework feeds some chillers and it isnt the most easy to get to.
Could someone please give me their take on this?

You quote edition 5 for your list, you say he quotes edition 3?? If you use the same base document it might help....
Any of these generic estimating tools take the rough with the smooth so that some take a bit longer and some a bit less, but on average it takes that long. If there is a lot of pipe to do then maybe the average comes down as the workers get more efficient.
Who knows?
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
