The Race To Fix San Francisco's Biggest Construction Mistake!

San Francisco’s tallest residential skyscraper is the 645-foot-tall Millennium Tower. Since its completion in 2009, the building has sunk several inches into the soil, and it is also leaning 26 inches at the top. A plan for retrofitting the sinking and leaning tower has been proposed, with an initial estimated cost of $100 Million. But the plan had to be revised due to an unexpected problem and now the cost of the revised fix increased from the initial $100 Million to an estimated $500 million. With millions of dollars at stake, for the engineers it's a race against time to fix this sinking and tilting building.
