General Contractor is working on the base building, which is required to be LEED CS certified. There is a tenant in the base building that is beginning construction prior to the fundamental commissioning of the base building. Will the tenant need to hold off on connecting to the base building RTUs until the base building has completed its fundamental commissioning? We do not want the construction of the tenant work to interfere with the LEED certification of the base building and vice versa.

I would assume that the RTU's will need to be commissioned before the VAV boxes (?) associated with the tenant-finish can be commissioned. As long as this is the case, I would not think that the tenant-finish portion of the work would have an impact on the CS portion. In the meantime, connecting to the system should not be an issue as long as the CS systems are following the commissioning process.

we have a very similar situation which is taking place - the pre-functional testing of the core & shell energy systems has been completed, and functional performance testing procedures are ready to be executed. based on a scheduling issue, the tenant - who will not be pursuing LEED CI certification - is about to commence their installation, in advance of the Core & Shell commissioning activities being completed.
assuming the tenant is to proceed with their installation, can we proceed with the commissioning activities and include the terminal equipment (eg. VAV boxes) associated with the tenant fit out within the core & shell certification? or does the HVAC equipment need to be fully commissioned prior to the tenant work commencing?

From your description, I am going to assume that the CS includes the primary systems, and probably the AHUs. From the CS commissioning standpoint, you do not need to commission the tenant terminal devices, although I could see a case where them being installed, even partially, would help in fully testing the central equipment. Similar to what Chris said (a very smart person by the way), as long as the CS systems are fully tested and documented there should be no issue, but it might delay your submittal some.
