Any number of factors might cause engineering to go awry. This type of structural design is mainly famous for multi-story construction as it reduces the thickness of the slab and overall height between the floors.

As a result, in 1975, record rainfall of nearly 7.5 inches of rain per hour (almost 42 inches a day) strained the dam to its limit. Following the disaster, the creator of the Pal-Kal method, Eli Ron, was arrested and convicted of 23 negligent deaths as well as negligent assault on the remaining victims.

This necessity was met, and a plan for supporting pits with post-tensioning cables to resist the earth pressures was formulated. Gregg Schlesinger, a contractor and lawyer in Florida, said that cracks and a kind of crumbling in the concrete known as spalling, also identified in the 2018 report, should have been a red flag if it seemed serious at the time.

The same idea holds for the reinforced concrete pilings deeply buried, vertical supports on which the entire building sat, said David Peraza, a structural engineer at Exponent, an engineering and scientific consulting firm. Hence they need to be placed at a minimum depth.
