The Overengineering Problem in MEP Design (en Inglés) - Charles Nehme

In modern Mechanical, Electrical, and Plumbing (MEP) design, engineering has become increasingly sophisticated, yet not always more efficient. Across projects of every scale-data centers, hospitals, commercial towers, industrial facilities-one recurring issue continues to quietly inflate costs, reduce efficiency, and complicate operations: overengineering.

This book is written to address that issue directly.

Overengineering is rarely intentional. It emerges gradually from conservative assumptions, fragmented communication, liability concerns, outdated practices, and a design culture that often equates "bigger and safer" with "better." The result is systems that are oversized, under-optimized, and more complex than necessary. While they may satisfy initial design expectations, they often fail to deliver long-term operational efficiency, flexibility, and sustainability.

The purpose of this book is not to criticize engineering caution-safety and reliability are non-negotiable in MEP systems. Instead, it is to challenge unnecessary excess, and to encourage a more balanced, performance-driven design philosophy. One that respects both engineering rigor and real-world efficiency.

Through practical insights, systemic analysis, and real-world observations, this book explores where overengineering originates, how it manifests across different building systems, and what can be done to correct it. It is intended to help engineers move from conservative estimation to intelligent precision.

Ultimately, the goal is simple: design what is needed, not what is assumed.
