I got a contractor to erect a facility with some duct work. The pipes have been delivered and, after taking measures on how they are placed at the site, for every pipe there has to be one or two of the parts to be cut to length and a flange welded on again.
Now my contractor tells me, such is extra work as he expected all pipes to fit perfectly, while my point is that it's impossible to fit20' long pipes with some knees in it so accurate that no cutting/welding is necessary. So he should have expected such work and also have priced it in in his contract. I have the feeling, he wants to try for every extra nickle and dime he can get from me.
Who is right? The contract itself states only "installation delivered of pipes" with a drawing and lengths.
