How They Built Skyscraper Foundations Without Modern Excavators

Long before modern excavators and heavy machinery existed, engineers were already building massive skyscrapers that still stand today. So how did they do it? This video uncovers the forgotten engineering methods used to construct deep skyscraper foundations using hand tools, steam-powered equipment, and sheer human labor. We explore caisson foundations, compressed-air chambers, and the extreme dangers workers faced beneath city streets. From early New York and Chicago skyscrapers to groundbreaking foundation techniques, this story reveals how ingenuity and brutal effort shaped modern cities. These early builders laid the groundwork—literally—for the skylines we recognize today.
