Great video! I liked watching the counterweight being installed too. The funny part though is that the excavator sounds like a vacuum cleaner! 🤣

Another fine video, John!! Fun to watch BERG's big Komatsu high-reach demo excavator working on the concrete-framed building. Another commenter (Construction Watcher) made a comment about wishing to see the boom installed; I agree with him, that part of the installation process would have been good to see. I wonder if the secondary counterweight that was installed behind the first one was a custom installation made to counter the front-end weight of the demo boom and crusher. Great video, thanks for continuing to post these fun demo videos. Keep them coming!

Thanks, John. It's great fun seeing a concrete muncher doing what it was designed to do. You got some good shots of installing the counterweight on the excavator. I would have enjoyed seeing the boom installed. Do you know why the contractor painted the color codes on the columns. I don't remember seeing that on other jobs. What is the orange paint visible on the penthouse at 8:40, for example. It looks like a very large bucket of paint was spilled. I was surprised to see a "finish" slab on top of the structural concrete on each floor. I suppose that made installing the under-floor ducts easier, but that doesn't explain it on the roof deck. Was that normal practice on this kind of construction?

I was sorry I missed the boom. They didn't install it until the next day, and lately it has been pretty busy around here. The operator is working from a demolition plan, and the color codes help keep him oriented. (Did I take out 6 columns, or just 5?) The orange paint up top does look like something spilled. I have seen big splatters created when an excavator crushes a can of paint left in a building, but I don't know how this one was created. The layered concrete struck me as rather odd. I don't know the history of it. Usually when I see layers, it is a thin layer on top put there for a terrazzo floor.

@@JohnZWetmore Thanks, John. I did see that this building had underfloor ducts for power and communications, and I can see that would be hard to include in the pour of the structural elements, but not in the roof.

Is all the steel being reclaimed out of the concrete?

That job is going to take a while!, surely they must clear away some of the rubble as they go or they will end up with a pile of concrete and metal as high as the original building!

They use the rubble to help the excavator drive into it to reach higher grounds.

super, your "pede's"...
