How a $500M Ice City is Built in 30 Days | Mega Construction

Once a year, an army of 10,000 workers builds a $500 million megacity out of nothing but solid ice. Larger than Vatican City and constructed in just 30 days, this massive logistical operation depends on ice harvested a full year in advance to survive the summer heat. To build 14-story towers in -20°F, engineers use specialized low-temperature steel and thermal bonding to prevent the structure from shattering like glass. From 93 miles of waterproofed cabling to a 1,700-foot ice slide, every second is a high-stakes race against the elements. Watch as they transform raw river water into a glowing metropolis—engineered to shine for 60 days before melting back into the river forever. 吴戟槐树 Bilibili: space.bilibili.com
