One of my favorite YouTube channels is the B1M. Apparently it is the most subscribed-to channel focused on construction. If you don’t already subscribe, you can do that over here.
Below is a recent video about Australia 108 in Melbourne. It’s still under construction, but it is topped out and it is now the tallest building in the country at over 300m. That makes it a “supertall.”
When you’re building this tall, it can make a lot of sense to segment and occupy portions of the building before construction is fully complete. Among other things, it helps to manage risk. And that’s exactly what they’ve done here.
