What is the purpose of a legend in MEP print reading?

The purpose of a legend in MEP print reading is to explain symbols and abbreviations used in the drawing. Legends serve as a key reference for interpreting the various symbols that represent components, systems, and other critical information within the drawings. This helps users to accurately understand the intentions of the designers and ensures that the technical details are appropriately interpreted.

Legends are essential for anyone involved in the construction, maintenance, or inspection of MEP systems, as they can greatly aid in clarifying the meaning behind the graphical representations found on blueprints or schematics. Without a legend, it would be challenging to decode the complexities presented in MEP drawings, leading to potential misunderstandings or errors in implementation.
