MEP Engineering & Building Systems by Use Cases for Mechanical, Electrical, Plumbing, Fire Alarm, and Low-Voltage Systems

Real-World Scenarios for Renovations, Upgrades, Expansions, and Code

By: Practicing Engineers Network

Modern building projects are no longer dominated by new construction. Today’s engineers are far more likely to be asked to modify, extend, replace, or integrate systems within existing buildings—often while those buildings remain occupied, partially undocumented, and governed by multiple generations of codes.

MEP Engineering & Building Systems by Use Cases was written specifically for that reality.

This book provides a practical, use-case-driven engineering framework for working on Mechanical, Electrical, Plumbing, Fire Alarm, and Low-Voltage systems in renovation, tenant improvement, retrofit, and code-driven upgrade projects. Instead of abstract theory, each chapter is structured around real-world engineering scenarios that mirror how projects actually unfold.

Inside, you will learn how to:

• Evaluate and verify existing building systems

• Identify code triggers and AHJ requirements early

• Safely extend and upgrade MEP systems without overloading capacity

• Integrate fire alarm, security, access control, CCTV, IT, and BMS systems

• Coordinate multi-discipline tenant improvement projects

• Execute phased construction and system cutovers in occupied buildings

• Prepare defensible documentation for permitting, inspections, and closeout

Every chapter follows a consistent, repeatable template that includes:

• Use-case overview and project triggers

• Applicable codes and standards

• Existing conditions assessment methodology

• Step-by-step engineering design process

• Worked practical examples

• Text-based diagrams and system sketches

• Common pitfalls and how to avoid them

• Engineer’s checklists for field and office use

This structure allows the book to function not only as a reference, but also as a working template that engineers can adapt directly to real projects.

Who This Book Is For

• Practicing MEP and low-voltage engineers

• Engineers working on renovations and tenant improvements

• Junior engineers and designers learning real-world workflows

• Engineering managers and reviewers

• Contractors and system integrators seeking better coordination insight

Whether you are extending an electrical panel, replacing HVAC equipment, adding fire alarm devices, integrating access control, or coordinating a full tenant build-out, this book provides a clear, defensible engineering roadmap grounded in real practice.

MEP Engineering & Building Systems by Use Cases is not a code book—and it is not a theory textbook. It is a field-tested engineering playbook for professionals who design, coordinate, and deliver building system modifications in the real world.
