In Core-and-Shell projects, where the fit-out is not part of the scope of the developer, we can't be sure about the final layout. We develop a feasible interior layout as is mandated in the Reference Guide. We will include this layout and the recommendation to provide views in the Tenant guidelines, and will include credit requirements so they can modify the layout maintaining the credit compliance. However, we are not in a position to make the layout mandatory through a Sales/Tenant agreement. The reference guide does not require that in the credit. But in the Core-and-Shell introduction it says that designs out of the scope of CS, should require a Sales/Tenant agreement. Do you have any experience with this credit in Core-and-Shell and help us to define if it's mandatory to have the Sales/Tenant agreement?
