I’m a fan of the Chinese Doom Scroll Substack where the author translates a selection of posts from Weibo. Great set on nannies today. But also this on the Hong Kong fire:

“Heard a Hong Kong architect talk about the skyscraper fire recently and he mentioned a shocking bit of logic.

Why were these skyscrapers getting their outer wall renovated at the same time? Why do all 8 buildings need scaffolds builded? Why have the scaffolds been there for over a year?

The reason is actually because no Hong Kong construction company has that many workers to work on all those buildings at once. You need thousands of people working at the same time for that, and once the work is done, those workers will have nothing to do and nowhere to go. So normally, you would build scaffolds on the buildings one by one and work on them one by one.

But in that case, it’ll be really hard for the construction company to get the money from the homeowners up front all at once, and it’ll be a slow process getting the rest of the funds, and there’s no guarantee you’ll get all of it. The construction company wrapped all the buildings up so they can get the downpayment all at the same time, but they can still only work on one building at a time. This way, the scaffolds stay on the buildings for a very long time. Over a year, in this case.

It’s because these buildings stayed wrapped up for so long that the bamboo dried out. Once a fire broke out, the risks is really high that it’ll spread to other buildings. Normally, the gap between the buildings was enough to prevent fires, but the extra width of the bamboo scaffolds made the gap smaller, causing this multi-building fire. So the biggest reason for this accident is bad construction order policy. They shouldn’t have wrapped all the buildings up for so long, just so they can get more of the downpayment.

I don’t know whether or not this Hong Kong architect was right, but if it’s true, then this is a very important lesson to learn. There should be laws made that if skyscrapers are getting worked on at the same time, the safe distance between them needs to be recalculated to avoid multiple construction projects going on in high density areas to prevent a similar situation.”

Comments say, “I don’t know if it’s possible to make a law that skyscrapers are not allowed to be taller than how high the escape ladders can reach or how high the fire hydrants can pump.”

“The last building to get renovated is so sad. It has to be all wrapped up for several years.”

“Hong Kong people are so polite. If it was me, due to my health reasons, I wouldn’t be able to put up with it for more than a month before I got frustrated.

"Hong Kong has one of the most laissez-faire economic systems in the world. For instance, their outstanding (and profitable) subway system is privately owned."

Which was also true, at one time, of NYC's subway. The one August Belmont (property developer and race horse breeding financier) built in 1904. But when he wanted to build a second line the politicians, greedy to share in the revenues, refused to let him do it without cutting them in on the deal. That was the seed of New York City's destruction of the subways (where it is today).
