Mehrooz Zamanzadeh, a Pittsburgh-based corrosion engineering expert, told ABC News on Wednesday that any cracks and spalling on the Champlain Towers South should also be examined to determine whether the vibrations from the construction next door played any role in the structural integrity of the condominium. Regardless, Zamanzadeh said the accelerated deterioration and corrosion of the Champlain Towers South was a critical factor in the partial collapse. He called for mandated corrosion inspections of buildings as well as a recertification process shorter than the town’s current 40-year term. ABC News

Water filmed pouring into garage of Miami condo minutes before it collapsed is likely part of the flooding and leaks that have corroded the building’s metal and concrete for decades, expert says

• Corrosion engineering expert Dr. Mehrooz Zamanzadeh told DailyMail.com he believes the disaster at Champlain Towers South was the result of accelerated corrosion of the building’s lower level
• This corrosion was likely caused by the salt in both the chlorinated pool water and in the sea water flooding the lower level
• Salt water corroded the concrete and steel in the rebar, reducing the thickness of these support structures
• Photos from the site show thinning concrete on the rebar in the garage area, a 2018 report found ‘failing’ waterproofing on the pool deck area and residents complained of longstanding flooding in the garage
• The new video of the moments before the collapse also shows ‘there is leakage and flooding due to more likely than not accelerated corrosion of load-bearing members,’ he said
• The video, posted to TikTok by Adriana Sarmiento, shows water gushing from the ceiling of the gated garage
• It was filmed at 1.18am on June 24 – 7 minutes before the building collapsed at around 1.25am
