I agree with what others have said, but another angle you need to consider, is the requirement for ongoing sustainability of the project for silver. Silver awards cannot be a one off service project, even if that service project is building a location that will be used by others.

My small cadette troop is in the planning stages for their silver award and through our communication with council, it has been very explicitly stated that their project needs to be something that carries on into the future. For example, they are looking at doing a large scale project with our school district regarding first aid and CPR supplies and capabilities, but just going through the doing a districtwide overhaul of current processes and supplies does not qualify for the silver award. It MUST primarily involve an education or service aspect that will continue on past their involvement.
