What role do notes play in MEP drawings?

Notes in MEP (Mechanical, Electrical, and Plumbing) drawings serve a critical function by providing additional information and clarifications that support the visual representations and technical details found in the drawings. These notes can include specifications, installation instructions, material types, and other relevant information that helps ensure the accuracy and proper implementation of the project. By including notes, engineers and architects can communicate essential details that may not be readily apparent from the drawings alone, thereby reducing the possibility of misunderstandings and enhancing the overall clarity of the plans.

In this context, while measurements and completion status might be referenced elsewhere, the primary purpose of notes is to enrich the documentation with contextual insights rather than to replace any requirements for precise dimensions or to cost-effectively track progress.
