NC-2009 MRc4: Recycled Content
Roof anchors are permanently installed - can they be included in the calculations? I've seen them specified in Division 7 under roofing, Division 11, and perhaps can bu under Division 10. I ask as Division 11 is not to be included in the calculations, but 7 and 10 are.
Thank you,

The recycled content percentage on the product data sheet is given as a range. What should I do?
Is the default average recycled content value of 25% for steel still allowed?
Can site materials, such as soil, be included in the MR credit calculations?
Are there recycled content claims that I should be wary of?

Where have roof anchors been specified for your project?
If your Project’s Specifications called out rooftop anchor devices in Div07 as a “Roof Specialties,” or in Div05 “Metal Fabrications,” include them in MR Credit calculations. If specified in Div11 as part of “Window Washing” or “Maintenance” equipment systems, exclude the devices from the calculation.
In any case, the cost of such devices is usually negligible relative to a project’s total material cost. Whether you include them in the MR calculation will probably have little effect, either way, on the overall Credit percentages.

Thanks Jon for providing this sound advice. I would anticipate the anchors would be specified in Division 07. I agree that the cost of these items will be fairly small and hence the impact will be negligible.
