Days pass in a partially collapsed building in Miami, and as rescue work continues, questions will arise as to how a 12-story building could collapse in 11 seconds.
Moreover, new evidence and details are beginning to emerge that will help experts determine the causes over time.
Since last weekend, the US media has released documents showing a significant decline in facilities south of the Champlain Tower.
This is the case Letter sent to apartment owners last April It warned that “the decay of concrete” was “accelerating” and that the damage was “beginning to multiply exponentially.”
The letter, sent by Jean Wodnicki, president of the Champlain Towers Southern Homeowners’ Association, was intended to explain to tenants why the 2018 renewal increased to about 9 million. Nearly $ 16 million Three years later.
Chaplain Towers South is a 12-story, 100-plus-unit condominium located off the coast of North Miami.
According to city data, the building was completed in 1981.
The building is subject to repairs as current regulations establish that this type of construction must pass an inspection in 40 years to confirm their habitat, which can be inspected by specialists and get its restoration, local officials said.
An engineering consultant, Frank Morabido, was hired in 2018 to make an initial assessment of the process, which he noted in his report at the time. “Lots of cracks” And landslides in the building’s underground parking lot.
This study found severe damage to the concrete slab below the pool deck – it “exhausted its useful life” – and problems at the entrance “cause significant structural damage to the structural concrete slab. Below these areas.”
By 2021, the building was in poor condition, as Wodnicki mentioned in his April 9 letter.
“Notable damage, as in the garage, Significantly worsened after initial inspection “, He wrote in the letter to which the newspaper was first approached USA Today.
“When you look at chipped (cracked) concrete, the remodeling that holds it together rusts and deteriorates beneath the surface,” Vodniki said.
Vodniki also noted that “concrete decomposition” “accelerates” “The roof condition has gotten much worse.”
“New problems have been identified. In addition, costs are rising every year. This is the highest number we have today, from the estimated $ 9,128,433.60 in Frank Morabito’s 2018 report,” he explained.
Wodnicki further warned that “it is not possible to know the extent of the damage of the base recirculation until the concrete is opened and broken.”
“Often the damage is more extensive than can be determined by examining the surface,” he said.
The letter, written to residents, gave them a darker picture than they had been given regarding the condition of the building, they say after the 2018 inspection.
Many of the survivors of the collapse say they were told the building was “in very good condition” at the time.
It is unclear whether the items identified in Wodniki’s letter are linked to the decline.
Experts warn that making hasty decisions about the causes is too quick, and although studies have determined “major structural damage” they do not warn that an immediate collapse is likely to occur.
This type of damage often occurs in older buildings, especially those facing the sea, and this does not mean that they are at risk of collapsing.
