FAQs about MRc4 :

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?

Can I count FSC-certified MDF toward both MRc4 and MRc7?

If I have one cut sheet that meets the LEED 2009 requirement to upload 20% of cut sheets by cost, for this credit, is that acceptable?

I have recycled content information for a product, but it doesn’t specify whether it is pre-consumer or post-consumer. What should I do?

The recycled content percentage on the product data sheet is given as a range. What should I do?

The manufacturer can't give me product-specific recycled content data, but they say that they fall within the national industry average. Can I use that?

NC-2009 MRc4:Recycled Content

Question about cut sheets

My project uses lot of steel and that is a very large portion of the total material budget. The supplier has not provided cut sheets to confirm the recycled content of steel. My other material items with recycled content (to which I have cut sheets) does not reach the 20% by cost threshold. Do you think since 25% default recycled content is a conservative value, LEED would still accept it without cut sheets for 20% of the material cost?

Magda - That is a good question and a situation I have not run into before. If any other LEEDusers have, please chime in. Here's my suggestion: Instead of not providing anything, I would backup the cost of the steel with some documentation from the contractor and then provide the Reference Guide stating the default 25% post-consumer waste value.
