To what extent is shop labor included in material costs? With increases in shop fabrication, this could be a big issue. Clearly there is labor that goes into the manufacture of every product, but at what point do we draw the line? For example, if a steel truss is manufactured in a shop and then shipped to the job site, is the cost of the shop labor included in the cost of the material? What if an entire kitchen is prefabricated? As in, purchased from a kitchen manufacturer, not manufactured off site by the project contractor. Would that differentiation matter? (This is for a 2.2 project.)

Also, if we have to pay a patent fee to use/adapt a product technology, is that considered to be part of the product cost?
