Clues to any of those problems will be clear only after the rescue operation ends, recovery begins and engineers dig all the way to the bottom of the debris pile, Mr. Peraza said. While no definitive conclusions could be drawn from the surveillance video, which was shot from a distance and reveals only one perspective of the disaster, some of the engineers reviewing it last week said it seemed to suggest that the failure began at a specific point near the bottom of the structure perhaps as far down as the parking garage beneath the building, or on the first few floors. Kemper Arena. But other structural engineers said that some level of corrosion was common in old buildings and was unlikely to bring a building down on its own. Progressive failure can also occur in fully constructed structures.

Generally, it is rare that a building is collapsed dur to foundation failure unless it is constructed on expansive soil. The extreme rarity of major building collapses in the United States deepens the mystery, engineers said, especially considering that Champlain Towers South had remained upright for four decades and had no obvious failure before much of it tumbled to the ground.
