How New York Built the World's Thinnest Skyscraper that Should Fall Over

World's thinnest skyscraper construction: how engineers built a 1,428-foot tower on a 57-foot site next to a 90-year-old landmark they weren't allowed to touch. A standard New York yellow taxi is exactly as wide as this building. To build it, engineers didn't just build a foundation — they drilled 200 rock anchors 30 metres into Manhattan schist to hold the building DOWN. They built two shear walls using 14,000 PSI concrete, four times stronger than standard. This documentary covers the full engineering and construction process—the impossible physics of building on a 57-foot strip of land, just 12 inches away from a protected 90-year-old landmark. From the foundation to the facade to the final storm, we cover the extreme engineering and hidden disasters nobody has explained before. What's in this video: How 200 rock anchors were drilled 30 metres into Manhattan schist to hold the building DOWN How 14,000 PSI concrete and 5.5 million feet of rebar were built into two shear walls on a 57-foot site How an 800-tonne tuned mass damper was built and calibrated to a 7.5-second period inside the penthouse How a 75-foot swimming pool was engineered to stop it acting as a battering ram during building sway How a 2-tonne marble bathtub was hoisted 800 feet up the exterior and guided through an open glass panel Subscribe to NEXTGEN MANUFACTURING to understand the incredible machines, blueprints, and megaprojects that built our world. #SteinwayTower #Megaprojects #HowItsMade #USA #FactoryTour #Engineering #StructuralEngineering #Construction #InsideTheFactory #Penthouse #Skyscraper #FullProcess #Aviation #Trending ⚠️ IMPORTANT: ABOUT THIS VIDEO ------------------------------------------------------------------- This is an educational documentary analyzing the engineering and construction of public infrastructure, based entirely on open-source information.
