We are working on an office CS project which is being built to suit for a single tenant. The tenant will fit out the core and shell with a LEED-CI project that is being designed concurrently throughout the CS construction. The CS CD's indicate designed recycling rooms at given sizes in given locations. A dedicated recycling storage area will be built on the ground level, however on the remaining floors, the tenant has requested that the Owner hold the construction of the recycling rooms so that they may instead be constructed in tenant preferred locations. It has been proposed to annotate the core and shell recycling rooms as being "provided by Owner in during tenant fit out per LEED requirements and in tenant preferred location". The recycling rooms would remain similar in size and centrally located on each floor. The Owner would still provide the recycling rooms, but the construction would not occur until the fit-out. Does anyone have experience with this type of approach, and if so, what are the recommendations for documenting this scenario?
