Rönesans Rezidans
Japanese Architect and Engineer Yoshinori Moriwaki also interpreted the collapse of Rönesans Rezidans. He said that the length of Rönesans Rezidans played a part in its collapse. A long building is fine but should use friction piles. Friction piles would have increased the price of the whole project by about 10%. The stakes would go all the way down to where the ground is more stable. He said that even though it fell over, there was actually not much damage to the structure. No matter how strong the building is, a bad foundation can lead to the building collapsing. According to some sources the building was constructed on a floating raft system which is a system used when the ground under a building is too soft  for friction piles.
