What is the purpose of elevation drawings in MEP design?

Elevation drawings play a pivotal role in MEP (Mechanical, Electrical, and Plumbing) design by depicting the vertical relationships and heights of systems within a building. These drawings illustrate how various components will be installed relative to each other and in relation to the overall structure, providing critical information about clearances, equipment locations, and interactions with architectural elements. By capturing the vertical dimensions, elevation drawings facilitate coordinated installations and ensure compliance with design specifications and codes, allowing all involved trades to understand how their respective systems fit into the space.

This focus on vertical relationships is essential in a multi-story or complex building environment, where knowing the height and placement of systems such as ductwork, piping, and electrical conduits can significantly impact both aesthetics and functionality of the design. While other types of drawings serve different purposes, elevation drawings specifically clarify how these components will come together in three-dimensional space.
