China's 117-Story Megatower Is Already Failing — Engineers Are Calling It a Nightmare

China's 117-Story Megatower Is Already Failing — Engineers Are Calling It a Nightmare Goldin Finance 117 in Tianjin, China topped out in 2015 at 1,957 feet, once among the five tallest buildings on Earth — and then stood open to the weather for over a decade after its billionaire developer Pan Sutong lost roughly $20 billion in a stock market collapse in just days. This video breaks down the real engineering behind China's tallest unfinished skyscraper, from the record-setting concrete pumped over 600 meters high to the corrosion, carbonation, and freeze-thaw damage a decade of open-air exposure actually causes to steel and concrete. We explain why simply "finishing" a stalled supertall is nearly impossible, why no engineer wants to sign off on a decade-old structure with incomplete records, and how Tianjin's Yujiapu financial district — built as China's answer to Manhattan and left empty for years — tells the same story at a larger scale. If you're into China's megaprojects, abandoned skyscraper stories, and engineering documentaries, this is the definitive look at the tower that may finally reopen more than a decade late.
