We are investigating the possibility of some renovation work. At the smallest it would be a connector from a second story walkway/hall over to an existing escalator platform. At largest it could be 8,000 sf of new second level floor space used for storage area or meeting room. The total facility size is 881,000 square feet. This amounts to less than 1% of the total facility. I believe the project would just require us to follow the LEED EB requirements for alterations, as we are within the 1-5 year documentation period - certified under LEED EB 2.0. There is another thought that it would be a new submittal under LEED CI. This is not a "tenant finishout". The facility owner is in charge of the renovation and while that area would be inaccessible during construction the building would not close. Please advise.
