How They Built a Skyscraper ON TOP of an 80-Year-Old Building

Here is the full breakdown of how they built a skyscraper ON TOP of an 80-year-old building, pulling off a true engineering marvel. In this structural engineering breakdown, we explore the impossible engineering required to construct Hearst tower directly above a historic structure without crushing it. Building over historic structures requires revolutionary overbuild construction techniques, from extreme deep foundations to complex load transfers. If you want to understand the skyscraper engineering process behind these crazy construction projects, watch closely to see exactly how the old and new merge perfectly in this incredible mega build. What do you think is the hardest part of retrofitting historic buildings like this?
