Look, stuff happens and when it comes to dealing with people's lives it's vitally important to “measure twice and cut once”. The China building collapse of the Lotus River Garden building is a sad testament that this doesn't always apply.
I believe there have been some workers that didn't make it out alive. This could have been worse and glad there weren't people living inside (if they were that would have been premature since the surrounding areas were still being developed).
I'm just shocked like something like this could happen when you have so many “eyeballs” on the project.
What makes this even scarier is that these so called engineers are spring up building all over the world with building codes just like the one in the picture above (building laying on their side).
