NC-2009 MRc4: Recycled Content
We completed the design of our project in 2013 and start construction in 2014. Some of the Declaration letters we received from the Manufacture (To Whom it may Concern) are dated before the start of our project. Is this acceptable or do I have to ask the contractor to provide an updated one.
Thanks

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?

Rezkar - I've never had a review team question the dates on my backup documentation. That said, I request recent information (~less than 3 years old) from manufacturers as part of my quality control process.
Three years is my own rule of thumb but it might be helpful to you; however, it is not set in stone. For instance, for steel I look at the mill certificates and ensure the backup from the manufacturers corresponds to the date to the steel was procured.
