1. Sinkhole City

When sinkholes collapse, so does everything on top. There’s a price to pay for not hiring a professional. A blazing fire destroys a residential tower and parked cars are suddenly crushed when the garage itself abruptly collapses. A Minneapolis bridge fractures and falls during evening rush hour, and bold, wacky designs translate into blueprints for the ridiculous. A newly built section in a Paris airport unexpectedly crumples and a newly built tower fails from a new technique. Finally, a 57 story high condo in downtown Manhattan is tall but not straight.
