Hi,
I'm dealing with a weasel contractor and I need another estimators opinion.
Using John Page's manual I get a, labor only, breakdown, per flange, that looks like this:
DN250 (10") ASTM 106B std wt pipe & Class 150 slip on flange.
Handling, into and from the shop is not included in this calculation.
Flame cutting 0.56 hrs.
Assembly, tack welding, manual welding (GMAW or MIG) with 3 X 9mm (0.35") fillet welds 5.3 hrs.
Supervision & visual inspection are included in the 5.3 hrs.
NDT & blast/paint are not included in this calculation. There is no PWHT.
Where did I go wrong?
Thanks in anticipation.
