text: A narrative is a comprehensive summary that could be published (in the newspaper for example) and should include such things as the definition of the project scope and limits, the purpose/intent/result of the project, the materials to be used, schedule, costs, funding sources, etc., as well as name of the owner, designer, inspector, and contractor.  Keep it clear, simple, and easy for any common person to understand.  Do not drown your reader in details.
