But the deep piles would have provided stability, Mr. Peraza said. 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. 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. Previous landslide deposits failed again. A temporary lift was constructed to help in moving equipment to various floors. The failure is now a case study for physics students.

Also, the adjacent post-tensioned reinforced concrete car parking structure collapsed. Thus, the strength of soil supporting the vertical support was lost and the building collapsed due to settlement. The concept of progressive collapse of structures was not much known to the engineers before the failure of the Ronan Point Tower.
