Why are annotations important in MEP drawings?

Annotations play a crucial role in MEP (Mechanical, Electrical, and Plumbing) drawings because they provide essential details and clarifications that are necessary for the installation and understanding of the project. They serve as a guide for contractors, engineers, and technicians by clarifying specifications, installation methods, materials to be used, and important dimensions that may not be immediately clear from the visual representation of the drawings alone. Without these annotations, individuals working on the project could misinterpret the drawings, potentially leading to errors in installation or construction. This importance underscores why clear and comprehensive annotations are vital for successful project execution in the MEP field.
