Our project is a 185,000 SF lab. The lab is served by a Satellite Energy Plant (SEP) of 6,265 SF, being constructed concurrently, but on a separate site. We intend to apply for certification for only the lab building and not the SEP. Both buildings are currently under construction and the contractor is tracking the materials and providing us submittals for the MR Credits. However the contractor is not able to separate the materials\' submittals (e.g. steel) for the two buildings, without considering it a change-order or requiring a re-bid from the sub-contractors. We foresee the SEP materials to be a very small portion of the materials used. We have detailed cost estimates based on construction documents that give us a split between the two buildings. We would like to use these cost estimates to calculate and thus split the relevant material quantities in the contractor\'s submittals so that we can count the materials appropriately for the lab building in our certification documentation. Is this approach acceptable to you? If not, can you suggest another approach, that would be acceptable given our circumstances, that would avoid a re-bid or change order?
