Report: Evidence of extensive corrosion in collapsed US condo

Corrosion was obvious and documented prior to the 12-storey building’s sudden collapse, which killed 98.

Video released by a team of United States federal investigators shows more evidence of extensive corrosion and overcrowded concrete reinforcement in a Miami-area condominium that collapsed in June, killing 98 people. The National Institute of Standards and Technology also announced Wednesday that it will conduct a five-pronged investigation into the Champlain Towers South collapse, which will be led by Judith Mitrani-Reiser. “We are going into this with an open mind and will examine all hypotheses that might explain what caused this collapse,” Mitrani-Reiser said.
