Our project includes a geothermal system. When calculating the total material cost I wonder in which division of the CSI masterformat should the cost of this system be accounted for. The installation of the thermal system consists of drilling the holes, filling them up with some special concrete type material and then putting in tubes. If I understand correctly the cost of the materials needed should not be counted in the calculation of the total material cost. Can anyone confirm in which CSI category these activities are to be placed and consequently if they count for the calculation of the total material cost?

I would include site work in Div 2 and the rest in Div 15. You may have some grout aroung the boreholes that would be in Div 3 but it isn't internal to the building.

Do I understand correctly from your assessment that I can include the metal from the geothermal tubes drilled 200'+ down in MR4 content (say even the basic 25%) in division 2 for my LEED2009 project? This is a very high cost item that would highly increase my recycled content figures I was led to believe I could not include as a part of Div 15 mechanical.

No, I would not include the cost of the tubes in MRc3 because they would be specified in Div 15 as part of the geothermal system. The best analogy would be AHUs which also are expensive, contain a lot of metal and are also not counted in MR credits. I think that only your site work would count.

My understanding regarding this issue is as follows:
LEED credits MRc4 Recycled Content, MRc5 Regional Materials, MRc6 Rapidly Renewable Materials, and MRc7 Certified Wood require the tracking of material costs for the project that fall into the following CSI MasterFormat 2004 Divisions 03 – 10, 31.60.00 Foundations, 32.10.00 Paving, 32.30.00 Site Improvements & 32.90.00 Planting.
For projects that are utilizing CSI MasterFormat 1995, the applicable divisions are as follows:
Divisions 3 – 10
Special Foundations and Load-Bearing Elements 02450 – 02490
Bases, Ballasts, and Paving 02700 – 02790 & 02335 (subgrade work)
Site Improvements 02820 – 02830 & 02850 – 02860
Plantings 02905, 02910, 02920, 02930, 02945 & 12810 (interior plants)
I am thinking that all of the Geothermal work falls outside of those specifications sections. Please let me know if I am looking at this incorrectly because I am working on a project right now that would be affected if there are portions of the geothermal work that would apply to the materials tracking numbers.
