Where can you find an index to the sheets included in a set of plans?

An index to the sheets included in a set of plans is typically located on the key sheet. The key sheet serves as a reference that lists all of the individual sheets included in the plan set, often providing a brief description of the contents of each sheet and its corresponding sheet number. This allows users to easily navigate through the plan set and find specific details or sections quickly.

In contrast, while the cover sheet may contain general project information, it usually does not detail the specific sheet index. The detail sheet focuses on particular construction details and specifications, rather than providing an overview of the entire set of plans. The title sheet, while it provides essential information like project title and location, also does not typically include an index of sheets but may contain other project-related information. Therefore, the key sheet is the most appropriate option for locating the index.
