The condominium board of directors needs to answer for this one. Let’s see the most recent facilities audit.
Yup!
If you haven't already, have a look at a report from a PE in 2018.
""At the ground level of the complex, vehicles can drive in next to a pool deck where residents would lounge in the sun. Mr. Morabito in 2018 said that the waterproofing below the pool deck and entrance drive was failing, “causing major structural damage to the concrete structural slab below these areas.”
The report added that “failure to replace the waterproofing in the near future will cause the extent of the concrete deterioration to expand exponentially.”
The problem, he said, was that the waterproofing was laid on a concrete slab that was flat, not sloped in a way that would allow water to run off, an issue he called a “major error” in the original design. The replacement would be “extremely expensive,” he warned, and cause a major disturbance to residents."
And that area of the worst structural issues he found sure looks like it's right in the area where the building collapsed first. Near the pool area.
The most significant structural issues begin around page 7 of his 2018 report.
