    How those excavators will be lift up or back on the exact ground level? What is the process of that. As they are 105 + ft down and digging the ground. . What they do to lift up the excavators to make them reach at ground level or any top to bottom they made temporary path or small road

    These deep excavations are mesmerizing when you are standing at the edge... it feels very surreal to see a giant box excavated out of the earth. The Georgia Hotel rebuild was 110ft deep - very impressive.
    To those saying conveyor belts would be better, it really just doesn't work in this environment, this is a hard heavy material, and a conveyor belt would have a hard time lifting it vertically. At an incline, it would literally need to be wrapped around the inside of the excavation in a spiral to get useful production volume, and just would not be practical. Triple handling the load between three excavators that are sitting in place is actually not that bad efficiency wise - when they need to move, that's where major efficiency impacts occur. Regardless, it's a slow methodical process and strict safety rules for shoring and stabilization need to occur throughout the process. Near the end, cranes with claw buckets are used to extract the last of the material, and often it's incorporated as ballast within the core pour if the material is suitable. As a last step, large cranes hoist these 120,000+ lb machines out of the whole like little toys. Next time you walk by a site like this, stop and appreciate, they are marvels!

    I’ve seen multiple comments about a conveyor system. The steepest angle a standard conveyor works at (around 30 degrees) would require a much larger hole or many conveyors to get to the bottom. Either way they would be in the way of the shot Crete shoring process, excavation and the constant changing depth would require constant modification to the system. A drag slat conveyor or bucket elevator system would possibly work but again the angle is probably too great as those max out at near 50 degrees, are not typically modular, usually aren’t longer than 100 ft and again would need to be constantly modified to accommodate excavation/ would be in the way of the shot Crete shoring process. This is the most efficient way to do this in this depth/footprint of excavation…… that why it’s basically done this way everywhere.

    • @richardcox8409
      @richardcox8409 Před 5 lety +9

      The angle required would have been too steep at some point to function properly and that pit is way past that point.. The different materials it would need to transport out would be a factor and would also impact the operational angle in addition to placing a size restriction on the material that can be loaded on the conveyor therefore possibly requiring more equipment and manpower to break down.. You could do it in stages but they take up a lot of room and would be in the way but your comment certainly brings a few ideas to mind...like a hydraulic powered, varying angle, wall hugging, modular step conveyor system, or maybe a vertical screw tube system..you could prob adapt an existing scissor lift platform and add conveyors as a conceptual design....im just thinking out loud here Im no expert but your light bulb inducing comment caught my attention

    I am amazed at all of the armchair quarterbacks proposing clamshells or conveyor belts to do this excavation. They so obviously know nothing about construction sites in a downtown core and the challenges that go along with them. But common sense should tell them that the companies contracted for this job just might have a little knowledge about what they are doing. These jobs are put up for tender and the lowest bid usually gets the job. Sure some contracts are awarded on a cost plus basis, but those are usually government contracts or large utilities like nuclear power plants and hydroelectric dams. Even then the costs have to be justified and are scrutinized every step along the way.

    Good job. We are going to have such a job, digging 10 meters (one third of yours). We will make a ramp while excavating and send dump trucks down to load the excavated soil. At the end, the excavator will dig the ramp from bottom to top to finish the job. In your case, with 105 ft, I don't think ramping would be possible. Have you considered this alternative?

      They spent $2.3 million to do the 48” bore holes. Forget about the beach, should have lowered the ground to sea level 300 foot around the money pit.
      Once at sea level either sink a wall as in this video or a sheet pile like they did on the beach, would cut any flood tunnels. Dig down slowly like an archeological dig.
      Since the pad looks to be about 40 feet above sea level, they would need to only sink a pit about 140 foot to bed rock and reveal all attempts at searching as well as flood tunnels and hopefully a money pit?
      Only hitch is if there are caves or cracks with access to water lower down and fill up from below hard to seal and pump out.
      Had they done this 4 years ago they could have saved money, dug through the winter with a covered pit and we would have had some kind of resolution, show is getting kind of boring with constant rehashing of what we already know.

    Pretty easy lift. The large Cat excavators weight between 80000lbs and 200000lbs so if they are the largest ones then about 100 short tons. They look like 352F's which are in the 120000lbs range so about 60 tons or so. A 200 ton wheeled crane like a Liebherr LTM1160 would make short work of lifting each of the excavators out of the hole.

    Fabulous video!! I am from NYC, and have never seen an excavation go that deep, since in many parts of NYC rock is not too far below the surface. The deepest I have seen for building foundations go down perhaps 50 to 60 feet. This video is impressive at 105 feet to bottom grade. Looking at this excellent video, I have a few questions: I see the tiebacks in the excavation walls. What kind of geology exists there in Vancouver? No hammering was evident, but a single-tooth ripper was in use. I saw that rock was a good ways down. Spoil had to brought up via relay, from excavator to excavator, working on benches to get the spoil loaded into trucks. Another question: The excavator at the street level was digging at maximum depth, well before bottom grade was reached. How was the spoil pile against that corner finally removed? I am guessing by clamshell? Thanks for posting this fine video. As a construction buff, I always enjoy seeing how things are done in different parts of the world. Thanks again for posting this.

      Usually the shoring walls (the concrete-covered walls that you see in the video ) act as the outside form for the actual walls of the building. There isn't an space left when they;re poured. Sometimes they even spray shotcrete directly on the shoring wall and finish that with trowels, that makes u the inside walls of the parkade.

      There's a reply below: conveyors aren't good at lifting heavy stuff. You'd have to build a massive spiral of conveyors, or an elevator. Either wouldn't be much more efficient than the excavators. You're only losing significant power efficiency when the excavators move on their tracks.
      A better question is why they didn't leave in a spiralling ramp as they went that trucks could drive down, and then excavate the ramp bottom-up at the end. Wouldn't even need to lift them out that way.

  • @SteamCrane
    @SteamCrane Před 5 lety +2

    Gotta wonder what they were thinking. It would have been much more efficient to use a medium size Manitowoc or similar crane with a moderately large clamshell, with front end loaders instead of hoes feeding the pile for it to dig. Wouldn't even need to be a very big crane to beat this production rate, and footprint on the street wouldn't be much larger than the hoe up on the surface. These mid-size cranes are readily available to rent, so you don't need to buy one. Agreed that conveyors might have trouble with the big rocks they turned up. This is a real misapplication of excavators. One or 2 would still be needed for the detail work that excavators are good at.
    Not rocket surgery!
