In which construction phase can I certify my building?

Construction phase of an office building is consisting of multi stages. Those stages are including but not limited to; excavation stage, concrete skeleton stage, block work and plastering stage, curtain wall stage, MEP construction stage, interior finishing stage, exterior finishing stage, landscaping and landscaping stage and so on. Now, I bought a new building that its skeleton ONLY had been finished and still the rest of construction stages not developed until now. I am planning to develop that building to be a green building through applying green activities in construction and design phases. I want also to register the building under LEED for Core& Shell rating system v2009. My question is regarding SSp1: Construction Activity Pollution Prevention. Can I achieve this prerequisite by implementing an ESC plan starting from this stage until the end of construction phase? The current building situation as mentioned is simply a concrete skeleton consisted of two basements, ground and six typical floors.
