I am working on a neighborhood project in Egypt , and we have been thinking to use LEED v4 for ND Plan , it is stated on usgbc official website that Plan: certification is available to your neighborhood-scale project if it’s currently in any phase of planning and design and up to 75% constructed

The project is currently in the schematic planning phase , and we would like to apply and acquire the certificate as soon as possible and before construction which will help in marketing for the residential units for the project, so i was wondering about the possibility of applying for the LEED certificate after finalizing the design stage is that possible ? and if yes , how can this be achievable when there is a prerequisite GIBp1: Certified Green Building which is impossible to achieve while the project hasn't started construction yet !

and what is the expected timeline for acquiring the certificate??
