Prior to demo/During construction we have installed MERV 8 on the return air units. But after construction the replacement of the filters is managed by the building management.

The base building HVAC system uses 100% outside air. Therefore there are no return grilles. I am assuming that the requirement for filtration then is not applicable?

Is a CI project required to replace the filters of the main building AHU? The project is a 5000 sf office space tenant in a 162,000 sf building (no AHU's in the space).
