The interior work had also started on the lower floors. 5 Disastrous Foundation Failures in New York City, Top 6 Energy-Efficient High-Rise Buildings in the World. 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. A third alternative using jack-piles was then considered. On January 15, 1919, a tank containing 2.3 million gallons of molasses burst and flooded the neighborhood.
