Italian construction engineer Riccardo Morandi, the bridge designer in Genoa, who killed 43 people this week, claims four decades ago that this building requires constant maintenance to remove corrosion due to the effects of sea air and pollution.
The RAI state television broadcasts a snapshot of the report that Morandi wrote in 1979, 12 years after a bridge was signed in Jan, with the name AP informed. Morandi stated that at that time there was already a "known loss of chemical surface resistance of concrete" as a result of sea air in the port city and pollutants from the nearby steel plants. According to his own words he decided to write about it, because this degradation is particularly "confusing" because of the "aggressiveness" of corrosion, which was not registered in similar constructions in other environments
