What is an MER?

Definition: What Does the Term MER Mean?

An MER stands for the mechanical engineer of record.

When a project is designed that requires mechanical design and planning, a mechanical engineer is hired. This project’s, mechanical engineer, will provide a professional stamp on the design documents that indicates their authorization to develop the plans as well as their responsibility for their accuracy and engineering competence. In many instances, the project will require that a special inspector inspect the project to ensure compliance with the MER’s original intent and design drawings. This special inspector will relate any concern or issue on the project, regarding mechanical design, to the MER. The MER is capable of accepting field deviations that have been noted by the special inspector. In many instances, the MER may not visit the project and will rely on the special inspector to relate any issues or deviations from what the MER had designed. The MER is considered a part of the design team along with the structural and electrical engineer.
