Which system NC or CI?

I am currently working on an airport terminal renovation project; 2 seperate terminals (non-contiguous) will be renovated (intending to register as 2 seperate projects). The scope of the project involves primarily interior renovation, interior walls, some restroom fixture replacement, some ceiling upgrades, some flooring and lighting upgrades, but will not be for either entire terminal, and will include no major mechanical systems, building structure or building envelope. The building is airport owned with only a few tenants. Can the CI rating system be used for certification? Or is it more appropriate to use another rating system?
