By Joel Brenner – Project Director, Group PMX
Skyscrapers are more than the offices, residences, observation decks, and public spaces most people experience. Behind their visible height are hidden levels that support the building’s essential systems, from mechanical equipment and structural transfers to fire-safety and refuge areas. These spaces may not appear on elevator panels or public floor plans, but they are critical to how tall buildings operate safely and efficiently.
Joel Brenner was recently featured in Newsweek discussing the concealed floors inside skyscrapers and why these behind-the-scenes spaces matter to building performance, safety, and long-term operations.
