Which of the following elements is NOT typically found on a key sheet?

The key sheet in a set of construction plans serves as an overview and is designed to provide essential information at a glance. This includes the project title, which identifies the project being undertaken; a location map that illustrates where the project is situated; and an index of sheets that lists all the drawings included in the plan set for quick reference.

In contrast, traffic control details are usually not found on the key sheet. These details are more technical and specific to the construction plans themselves, typically appearing in their own designated sheets within the larger plan set. Traffic control details require a level of specificity and precision pertinent to the construction or operational context, which is not suited for the broader, summarizing purpose of a key sheet. Therefore, the lack of traffic control details on the key sheet aligns with the function and design of this element in plan sets.
