Hi. I have two projects were the contractor has given me the recycled content (RC) information of structural metal products. But, the cost of each product has not been itemised. In other words, for example I have: Angles with their RC, steel tubes with their RC, wide flanges with their RC, etc., but I have only one material cost for the total of all of those elements. My question is, can I make an average of all of the RC contents and use that average to calculate the cost contributing for recycled content? There are no weights to convert it into am assembly
