Systems Within the Structure: Why MEP Integration Has Become a Foundational Engineering Priority

Mechanical, electrical, and plumbing systems were once treated as building accessories — components layered into a structure after the primary engineering decisions had already been made. That model is no longer viable. As MEP networks grow in complexity, weight, and spatial demand, structural engineers must account for these systems from the first day of design, or risk consequences that compound well into construction and beyond.
