MEP stands for Mechanical, Electrical, and Plumbing engineering. MEP engineering is the science and art of planning, designing, and managing the MEP systems of a building. An MEP design company specializes in these skills and is also known as mechanical, electrical, and plumbing engineering consulting firms. MEP engineers partner with other disciplines to help design buildings, and they are responsible for ensuring that the mechanical components of a building, such as the HVAC, are working properly. They also perform other consulting services, such as reviewing designs from other engineering firms for code compliance, troubleshooting MEP systems that aren’t operating correctly, optimizing central utility plant designs, and short circuit coordination and arc flash analysis studies. MEP engineers are uniquely equipped to help building owners stay under budget, maximize their investment, and make strategic decisions about materials, processes, and technologies.
