No other book shows you how a real skyscraper actually gets wired — from first estimate to final drawings.
Most electrical engineers graduate knowing the theory. Nobody teaches you how to size a medium voltage distribution system across 76 floors, how to coordinate five transformer substations, or how your schematic design load estimate compares to what actually gets built.
That gap is what this book fills.
Written from the engineering record of a real high-rise project in New York City, this is a step-by-step walkthrough of how a building's electrical distribution system gets designed — from the first VA-per-square-foot estimates in Schematic Design through the final panel schedules and one-line diagrams in Construction Documents.
The book covers:
-
Building classification under IBC and how occupancy type drives every electrical decision
-
Load estimation methods for residential, commercial, amenity, and MEP floors
-
How to develop a one-line diagram from scratch and refine it across design phases
-
Medium voltage strategy and transformer substation placement in tall buildings
-
Emergency power systems — generator sizing, ATS coordination, and legally required standby
-
The gap between SD estimates and CD actuals — and what it teaches you about contingency planning
-
NEC Articles 220, 620, 700, 701, 702, and 230 applied to a real project
This is not a textbook. It is what a senior PE would tell you on your first day working on a skyscraper, if they had the time to write it all down.

The most common question junior engineers ask when they start working on residential high-rises is how to size an apartment feeder correctly — and which NEC method to use at which phase of design.
This free worksheet answers that question directly, drawn from Chapter 4 of the book. It covers the Standard Method, the Optional Method, and multi-unit feeder sizing using NEC article 220 III, with worked examples from the real project and a pro tip on which method belongs in SD phase versus CD phase.
