I have few clarification of whether the old constructed portion material should be considered for all the materials credits.

The building has been developed by the developer which including the structure (column, beams, roof, operable windows etc. for G+8 floor). They have not started any interior work. At that stage, the building has been procured by our client and replacing the operable window with Aerocon block wall. The client has not demolished any structure except lift which has been changed little bit.

Client is constructing the interior in phase wise. (i.e G+2 floors will be completed within 6 months from now and will be occupied and operated. Then remaining all other floor interiors will be started one by one and every 6 months one floor will be completed & occupied. All the floor interiors will be completed and occupied by 3 years from now.

By considering the above project description, we have two queries.

1. For MR Credit’s calculation, if we consider only the materials involved & construction waste generated under the scope of work done by our client will be okay or should we consider the materials & construction waste generated by the developer who has done till the structural development.
2. By considering the whole building will be completed & operated by 3 years from now, but the first phase (i.e G+2 floors) will be completed within 6 months from now, how to go ahead with certification. I mean when should approach Green Building Council for documentation. Should I submit the documentation once first phase is completed (i.e G+2 floors).

Hope your experience will be helping us to overcome this issue. Your reply at the earliest will be highly appreciable.
