Per CIR ruling dated 1/28/08, we feel there may be some flexibility in CSI classification of materials and how that qualifies a material for inclusion in Recycled Content (and other Materials & Resources credits) calculations. The particular material of concern here is "RF Shielding" panels to be installed in the MRI facility of our hospital expansion project. These panels are typically classified under CSI Division 13 for accounting purposes, because they are a specialty item. However, the panels are being custom fabricated in a shop, for this project, of a few simple materials, mainly: urea-formaldehyde-free recycled MDF and copper sheeting Because of the high recycled content of these two materials, we would like to include them in our recycled content calculations. We feel that because of the simplicity of this component, and our subcontractor\'s ability to break out the cost of each material and recycled content data, that we should be able to claim credit. Please verify.
