To build foundations in the wet soil adjacent to the Hudson River, engineers constructed a 3,500-foot-long concrete underground "bathtub". This prevented the Hudson from flooding the excavation site and became a marvel of civil engineering. IV. Economic Symbiosis and the Globalized City
Before the construction of the complex, Lower Manhattan was defined by narrow, winding Dutch-settlement streets and early 20th-century skyscrapers built on small lots with severe setbacks. The WTC broke all established rules of this environment:
Module 3: The History of the World Trade Center - 911 Memorial
The Port Authority razed 16 acres of active, small-scale industrial and electronic shops (the famous "Radio Row") to create a singular massive superblock. This permanently de-mapped several historical streets, detaching the complex from the traditional Manhattan street grid.
The dedication of the World Trade Center on April 4, 1973, marked a physical and psychological shift in the skyline of New York City. Standing at 1,368 feet (North Tower/1 WTC) and 1,362 feet (South Tower/2 WTC), the Twin Towers were briefly the tallest buildings in the world. However, their true impact lay in their relationship with Manhattan. Spearheaded by David Rockefeller and the Port Authority of New York and New Jersey, the project was designed to aggressively pull the economic gravity of the city back to Lower Manhattan. II. Architectural Scale and the Grid Disruption
Instead of using a traditional grid of heavy interior columns, engineers Leslie Robertson and John Skilling moved the load-bearing columns to the outside perimeter. This left the floor plates completely open and column-free, offering massive acre-sized workspaces that financial corporations demanded.
