WE are working on a LEED ND project and are currently incorporating the LEED requirements in the project specifications. We are trying to cover in the specs what the contractor needs to document and submit .By reviewing the dynamic credit forms (templates) for some credits, I am noticing that there is not much upload requirements as there would be in the LEED NC forms for similar credits. For instance, neither credit GIBc13 nor GIBc15 seem to require any documents to verify efficiency values, recycled content, model numbers, etc. - Normally, letters from manufacturers and/or technical cutsheets, are required to support the project team and contractor claims to earn such credits. Is LEED ND less stringent in documents submission?
