Start of the demolition of the switch room to the old power plant at Purdue University (Ignore me talking to an Exponent reporter, you're still not getting this video).
Looks like a very well engineered and built old building. Seems a shame to have to demolish it. It would look a lot better, if it weren't for the giant, rusty, duct works exposed on top.
Clamshell not very effective in this case. Wrecking ball seemed to do the job slowly but surely. Super cheap way of doing things vs the paperwork involved with explosives. Old crane using probable 11-15 litres of diesel per hour vs a huge 75 tonne long reach excavator that probably costs $400,000 new and has endless systems to go wrong.Video is 24 minutes long. Leave him for 10 hours with that ball and see what is left.
I’d put the wrecking ball on Line it up turn the boom at least 245 degrees away from the building,wide open back towards the building and hope you don’t miss and turn the crane over.
lol they do? anyway the clam shell you dont see too often but it works and its precise if not slow to bit off load by load, I just hope if they are going to be ripping down buildings they let the students of the class take part, they can use the practice, and let them take care of their own, its rightfully the schools, and the place of the professors and students that are going to be specialized in the trade. you know
Hydraulic high reach excavators with shear and gripper attachments are more efficient that cable supported clamshells and wrecking balls. The high pressure hydraulics generate a much greater force to gripper attachments and shear attachments (I Beam slicers)
The modern high reach excavator attachments can be adjusted 360 degrees to pull a beam or column or wall down from any angle. The old cranes have to be assembled in sections at demolition sites and disassembled and prepared for transport once the demolition is finished. Very time consuming.
Wouldn't an implosion been faster and more cost effective? This guy is taking forever to do one little thing. Not a good use of time and money, especially when the crane operator is losing the battle with a very well constructed building. If it were me, I would have saved the building and repurposed it instead of demolishing it.
quite the contrary its the cheapest and most cost efficient way it just takes a while. As far as re-purposing, some buildings may look fine on the outside, but many times when neglected like this, a building can be beyond repair unless the someone is willing to submit massive funds to repairing it to even make it safe. Unfortunately most universities aren't really that good at preserving history
Those steel beams were mighty strong, and not just that, they were very, very heavy, if this building here had a steel structure made of those kind of steel beams, and then it came to tearing it down, you might be talking about a pretty risky task that will require extra care, a steel beam lands on an excavator, the excavator would either need massive repairing or otherwise be scrapped. Those steel beams on the twin towers, if one falls from a good height and hits lands on another building, there’s a some decent damage to that building, at the base of the twin towers in between, there was a small Mariott building, when the south tower collapsed, because of all the falling debris, the Marriott building looked like an earthquake cause the middle of it to collapse, when the north tower collapsed the Mariott building was look like nothing but charred ruins and debris

What a dreadful waste of time. The clam shell was useless, the ball not much better. A high reach with shears could have had this wall down in a fraction of the time and sorted the materials.
