In a sense. Quite recently, they say, engineers did routine checks.
There are engineers and their are engineers. Perhaps they were not qualified. The cracks showing that there is a danger of
building collapse do not suddenly appear., unless there is an earthquake that did not happen. The cracks build up
gradually more than enough time to be discovered by a competent engineer. Most likely reported by the condo
occupant.
Just sloppy construction and not paying attentions to details. And there are the coverups for some unknown reasons.
