why wait for the facts? unless someone wrecked their car into the jobsite, this failure occurred during construction where the building standard is "good enough", once that level is reached then it's off to the next job, I see this standard in everything here, so of course there will be plenty more mistakes than a country whose standard is "as good as possible". I imagine there's an official construction inspector that monitors progress and safety, but is there really? unskilled workers doing the job while bosses are napping/scrolling and not supervising, it's not surprising . it would be surprising if this wasn't worker error and I'll be happy to be proved wrong after the investigation, you can tell me so if it turns out that way, and I'll do the same (after I'm proved right????)
