Fabrication Labor

I'll answer the question you DIDN'T ask first. In LEED-NC 2009, you don't get any credit for stuff that's manufacturered within 500 miles of the project site unless it's also extracted/harvested within that zone.Now, about the question you did ask--there are a couple of ways of distinguishing materials cost from installation cost. One is by what happens on site (installing stuff) as opposed to what happens off-site (making the stuff). Another is by who does it--a supplier makes the stuff, and a contractor or subcontractor installs it. The latter is cleaner because you'll have invoices showing the value of the material as it is transferred from one entity to another. So I'd say that you can try to count the fabrication labor in your material cost, but be prepared to have it questioned and/or rejected.

I suppose you can do it this way but as Nadav suggested I would be prepared to have it questioned. In a sense the whole building is being assembled on the jobsite. Yet construction labor is not counted toward MR credits. This sounds like it has a lot in common with construction labor, rather than factory labor.

Rebar - Typically when we purchase rebar from a commercial rebar supplier/fabrictor embedded in their material price delivered to the job is fabrication cost of cutting and bending the rebar. When we hire a concrete subcontractor the rebar typically but they will buy straight bar lengths take it to their shop and cut and bend before bringing to the site. Are we correct to assume in both cases this cutting and bending cost should be included in the material cost?

Yes, but I would be consistent in applying this methodology to all of your MR documentation.
