An MEP engineer (Mechanical, Electrical, and Plumbing engineer) is in charge of setting up, integrating, and also making sure that the entire MEP system is working in the buildings. They focus on projects like residential, commercial, and even industrial buildings, where the HVAC, the electrical wiring, the lighting, and the water supply systems are designed and implemented to ensure maximum comfort, safety, and efficiency.

MEP engineers join hands with architects and contractors to incorporate such systems as a part of the whole building approach, emphasizing compliance with codes and guidelines. A significant aspect of building projects is the proper functioning and longevity of which these engineers oversee installations, diagnose problems, and give recommendations for equipment advancements.
