I know this is kind of out there, but we have a situation where the GC has only provided unit pricing for wall assemblies (per sf) and not a cost breakdown of the individual components. Using a typical wall detail, and the recycle content info from the drywall, metal stud, and insulation cut sheets provided, can I use the Assembly Calculator and come up with a cost/sf, that would contribute to MRcr4, then apply that to the total sqft of wall built, and get the USGBC to accept it? I realize the logical thing to do is to got back and get the component pricing, but we are getting short on time and I don't know how cooperative the GC will be at this point.

Charles - My first approach to your response was to follow your logical reasoning and get the pricing but your situation sounds challenging. I wasn't sure if the assembly methodology would be acceptable but a USGBC staffer indicated to me that it is acceptable to treat the wall as an assembly and use the weight calculation method. Good luck finishing your documentation!

Thanks Michelle. Hopefully it won't come to that; but as a last resort, it's certainly better than walking away from the points altogether.
