Previous CIRs indicate that the mechanical and electrical components are to be excluded from the calculations for Materials & Resources credits 3, 4, 5 & 6. Please confirm that the total material cost excludes these components as well. The total material cost will either be the actual material costs of the Div 1-10 subcontractors or 45% of the total construction cost of the Division 1-10 subcontractors.If items from division 15 or 16 are assembled locally and can be included in the numerator for the total of the Regional Materials calculation, should the materials cost from division 15 and 16 be added to the denominator as well? Please clarify
CORRECTION, 10/25/05: To attain the materials cost using the default calculation option: begin with the total subcontractor charges (to the General Contractor) for CSI MasterFormat 1995 Divisions 2 through 10 ONLY (instead of all Divisions, as indicated in the original ruling). Applying 45% to this number (as the Letter Template does) will result in a conservative estimate of the materials costs in those Divisions.-----------------------------------------------------Original ruling:To use the default 45% calculation to generate a total materials value, project teams must enter total subcontractor costs of all MasterFormat Divisions. This is noted in the LEED v2.1 Letter Template. The resulting cost solely represents materials in Divisions 2-10 (currently this is not indicated in the Letter Template, but should be). These Divisions include the principal items that are considered in MR Credits 3 through 6. Materials in Div 11 through 14 are optional (item by item), and if included must be added to the numerator and denominator of the equation.If a project team chooses not to use the 45% default calculation to generate a total materials value, then follow the guidance provided in MR Credit 4.1 CIR ruling dated 8/29/2003: Materials in CSI MasterFormat Divisions 2 through 10 must be included. If a project team chooses to include additional items as part of the base material costs it should do so for all relevant material credits, which include MR Credits 3, 4, 5 and 6. See the MRc4.1 8/29/03 ruling for further details. Applicable Internationally.
