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
They used a heavy lift crane like this one th-cam.com/video/C79Ejh4RfLs/w-d-xo.html
I've seen helicopters used to pull machinery out. But this looks like a pretty populated area, so they most likely used a crane
Derrick crane
@@dave_in_florida oh okay
@@agartha8942 Here are the same excavators at a different site th-cam.com/video/EE36cai9y18/w-d-xo.html being lifted out.
With the price of Vancouver real estate, they went this deep to get 8 stories of underground condos with the sales pitch stating, "Bedrock View".
rock garden terraces.
With starting prices for 450 square feet starting at the low low price of 8 million dollars. Lol.

Cool video, I've just been watching a company excavating some foundations in Manhattan, got me wondering how they do it and I found your video. Thanks for taking the time to put it all together.
Amazing how level, plumb and the hole is. Great job!
No doubt they were looking at the plans upside-down.
Underrated comment
Lol
Crap we were supposed to build up!
Nice. We finished boaring pile ons in Melbourne 150ft down into the swamp. This is lovely work to see.
@Slopalong Joe lol fanks
Extreme Excavator work! Really amazing.
Great job and VERY nice drilling and shooting!
Cool urban construction video. I'm looking forward to recording the same in Chicago as soon as it gets warm again here.
Wow... this is cool. Thanks for sharing!
That's a deep one! must be twice as deep as anything I've ever worked on, very cool to see.
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 had actually wondered how they got the excavators out, as the only crane i could see was that tower crane.

Great video, super. Greatings from Poland
Pretty amazing piece of work.
Superb work, and in the video we only see the result of the real critical work : to do the contention walls to avoid collapses. That is the structural key of the whole further works, if you imagine the soil load against all that long and tall wall you can get scared. Congrats to those who calculated and made that critical part and thank you for upload video.
Looks like they drilled in anchors.. wonder how they managed to not hit utilities of the buildings surrounding the site.
@@frontrowal8656
Anchors (the machine for that is visible, mostly covered with tarps, 2:12 for example) and spray on concrete (visible in the vid around 1:12, right rear corner) and probably steel mesh (not shown afaik).
Magnifica perspectiva de un solar en construcción y el empleo por parte de una de las excavadoras de una especie de uña en el lugar del cazo.No lo había visto en obras en España!!!!!
Waauuu...amazing..👏👏
I like when building owner think about parking space. We need this guy in Krakow.
My old man worked for Lafarge and before Lafarge came around, he's been on almost every jobsite in city, including rebuilding the footing under lions gate bridge, Stanley park side, I went with him on that job, BC Place Stadium, skytrain etc, it's endless. This hole is shallow compared to some of the buildings
Wow, omg, u are a national hero!
That is gonna be one heck of a pool once completed.
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.
Came across this construction site, using a conveyor to extract the dirt from a swallow pit imgur.com/a/KdhPeP8
@@Zepfancouver Those pictures illustrate what I’m talking about. The angle becomes a problem as the depth increases. In a shallow hole it would work. But realistically…. 2 349 excavators would still be much faster/more cost effective on that site too.
Line it with decorative tile and you have a pretty
impressive swimming pool.
LOL I'd call that a drowning pool, myself :-D or a submarine pen.
A time lapse video showing this would have been one of the best things to happen, oh well, thanks anyway
I"ve casually seen a few deep excavations in Vancouver - like the Canada Line section of Skytrain. What is that blue-grey ground material and how deep does it go? It seems endless and not to bad to work with for stability and consistency. Looks like glacial (marine) till - but sooo deep
Being that close to the edge my stomach would have butterflies every time I reached inside the hole to scoop material.
wow...great catch here.....getting those excavators out must have been something to see for sure....surprised they didn't hit water down that deep...* thumbs up from ....... ;-)

Yeah it'd would've been nice to see the removal of the excavators. Thanks for sharing!
There was water, they were just managing it with those bypass pumps. The large yellow structure is the tower crane. Pretty cool site.
*I dig as deep as that trying to find a pair of matching socks every morning*
😂 too true!
@rats arsed I can't wear them long with a hole I get bothered by said hole and ultimately go hulk on the hole and tear it until it can't be worn by hulk anymore.
@rats arsed the good one have one hole, the bad have more then one :-)
you made my morning with that simple but very relateable (sp?) comment!
Great job 👍😊✌️
Great job ❤
Those are some realistic looking RC toys.

Like these -"donsiggio" TH-cam Page th-cam.com/users/donsiggiovideos?view=0&sort=dd&shelf_id=1
Some places have sinkholes. This one looks like a shithole. Unless of course you give us a follow up and turn out to be a DTT. Then it would really be something right?
i miss the part when they got the excavators out the hole
great video anyway, good job
They use cranes and lift them out
Great video bro
Impresionantes mega construcciones .😱😱😱
any simpler machinery for this ?
a shovel?
This is "Umbrella Corp" - beginning.
You mean, BENINGING (:
A very large Manitowoc 7 yard cable clam shell bucket crane up top be more efficient.Could reach most of pit floor.
Nice job.
yah clamshells have really gone out of style for some reason
Brian Branson Still used in beach front dredging and break water jetty rocks alot. New ones are hydraulic .I learned on pure friction rigs.
will this place end up requiring like a permanent bilge pump?
I wonder if they were tempted to just keep digging and see where they ended up?
That's one deep hole..cool video btw.
That's what she said.
I saw an excavation like that , when they make one of the Casino in the Las Vegas Strip, they use the depth , to put the parking garage in the bottom.
Interesting which one on strip or off
I love to see a video on how you got those big digger out of the hole
Cormac Keenan A crane
Manitowac 18000. All out in 8hr shift.
nice cuts nice video :)
Damn, thats hella deep!
How did they do waterproofing of basements? What was the methodology? Was there in soil backfilling between basement walls and pit walls?
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.
Good work...
What type of material was that I seen no shoring on the sides!
They call it shotcrete (spray-on concrete) - Drilled holes in wall for tie rods, installed meshing then spray on concrete, like this th-cam.com/video/o-6wNyYChV0/w-d-xo.html a site (Alberni by Kengo Kuma) not far from here.
That would be a really great place for a building once they're finished excavations.
impressive. imagine the planning that goes into a project like this. is it still under construction now? (June 2019)
Yes it is forum.skyscraperpage.com/showthread.php?t=186101&page=66 Pictures and comments on the progress.
어마어마하군요
I wonder how many cool artifacts, bones, fossils, etc are digger up and never found in construction like this. They just get relocated and used as clean fill somewhere.
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?
Anyone know the soil type for this part of Vancouver?
Looks like very hard clay from these angles, and from the types of equipment being used.
Shale Rock, compacted mud and clay. This construction site is only 350 metres from the shoreline so the hardpan on this dig began only a few metres from the surface. (Disclosure: I'm no expect or geologist.)
Rock flour, very common in this region. It can be found as far as west Langley.
They did this in Seattle way back with steam electric shovels and conveyors that loaded barges and dumped it into the bay. Denny regrade I believe
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.

In DC, almost all new construction has deep excavation
What are the cylinder things for at 7:00? It looks like a tunnel that men can climb down, but for what? How high up does it go?
Those are catch basins, they don't go higher, they're about 10 to 15 feet deep, it catches water that trickles down into the parkade. They're installed with pumps so they can be drained when needed.
@@Zepfancouver Thanks, awesome. So they're drains under the whole building that pump water out? Amazing!
Is it legal not to have the scaffold stairs end with a 20 foot ladder? what if someone is injured and needs to be evac'd?
They need to dig, shore and shotcrete that area as they dig down. I guess it's needless work to build and breakdown scaffolding.
what is that retaining wall method called? is it a Diaphragm cut off wall?
Shotcrete method - Drilled holes in wall for tie rods, installed meshing then spray on concrete, like this th-cam.com/video/o-6wNyYChV0/w-d-xo.html a site (Alberni by Kengo Kuma) not far from here.
Thanks for the great video! My question is: how is the excavator retrieved from the pit/excavation ?
I missed the egress of those excavators, I knew the day is was going to happen but I had to work that day.
Here are the same excavators at a different site th-cam.com/video/EE36cai9y18/w-d-xo.html being lifted out.
One day I will capture an excavator being lifted out of the pit.
There is one in Portland, Oregon that is 8 parking levels. Don't know how many feet.
Khadijah Brown average story level is 10ft...so 8 storys...this is 10.5 storys down...it is deep.
I have a question. What if the excavators are down there while it’s raining really hard. Will it start to flood down there?
At 1:14 - 2:00 - 3:16 and 4:20 I see only one pump getting the water out. I guess that's all they needed to control pit flooding.
4:51 The topside excavator is working blind.... the operator can't even see into the pit.
they've got cameras
nice
The Claw! I have a CLAW sighting!
SUPER
So are the side walls slurry walls? How did they get the excavators out afterwards?
Yes, shotcrete (concrete spaying 1:06 ) Heavy lift crane.
Looks like good operator skills was involved in this,
How do you square something like that up
matt motta Lasers and a survey crew.
Thought this was one of those billionaire basement stories: guy buys small house in London, Manhattan and can't go up so they dig down. More than one story from England where they had to leave the backhoe down in the hole. Took it down in pieces and couldn't fit the pieces up.
Why didn’t they use a conveyor?
Because that would of been to easy and they couldn't of charged as much for the work
I was thinking the same thing. Probably would be a huge chunk of change to make a custom setup then to have it not be used again or for at least a long time and having to keep it somewhere afterward until needed again or until scraped or sold. Sounds like a headache really to me lol. I could be way wrong tho idk.
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
@@richardcox8409 They have different kinds of converyers.
That's a good point about the angle but you could have a converyer that has buckets and you would only need minimum angle.
They probably just made best with what they already had.
I thought about the belts that have the small bars on them after i posted and never thought of buckets like a dredge...and yeah Im with you on the "just made the best"
How do ya clean the corner out?
500 day laborers
Nice
how long did it took to dig that deep? how much was it? I wanted to see how u guys were able to take that huge excavation machine out from the base.
It took 10 months. I don't know how much it costed, I would like to know. I don't work for NorLand Limited. I missed the removal of the excavators, was at work that day, NorLand Limited posted a great video of removing the excavator on a different project norlandlimited.com/news/lifting-two-excavators-100ft-deep
@@Zepfancouver wow 10 months, not bad. Thanks
My question is where do they put all the dirt that comes out of the hole. I dig a small hole in my backyard and I struggle to get rid of it.
Dump trucks haul it off
They dig another hole somewhere else and put it in there!
ORGANIZED CoNfUsioN Lmao your right
Land fills
Talented operators.
Nice video of an interesting job.
Having worked all my life in foundation and piling I have a fair idea.
When working down there, you have to trust those who designed and executed the anchors rods !
men love hole work.
What type of excavation is this? What 's the name for this excavation method?
I not sure what you would call this kind of excavation, I would call it ' Get it done method '

In NYC the unions would have 250 people on that job. 1 to operate the excavator and the other 249 to "supervise".
Lol that's pretty good....here in Australia things are very similar at times...especially our local council workers....I remember once I drove past some local works and someone had spray painted a sign that said.....more padded shovels required...says it all.
You're thinking of city workers buddy. UNION for life
Yeh well unions can be a bad thing also.....building sites being held to ransom by unions over the most stupid things...we have one atm here....a 300million dollar high rise tower stopped because the government acused them of getting underworld figures here to stand over workers that complain about unsafe working conditions. And at the other end of the spectrum we have unions that demand unrealistic wages for workers...e.g..$38 per hour for a site cleaner....picking up offcuts!!! And wonder developers go bust!!! So union for life my ass!!!
It was at the 104 ft Mark when they realized you can’t actually dig to China and the new trade route was doomed to fail.
umm i get having saftey regs but why in the hell do the guys working down on the floor have on fall protection? 🤔
Just the rebar workers. They're sometimes 10ft or more up on the rebar curtain tying rebar.
The workers will often leave the fall protection on for working at height in the hole like climbing up on columns etc. Also climbing in and out of the hole to lunch room and tool crib to get fall protection every time they need it takes considerably more time .
How did u get the excavators out of there and the balance of the soil
With a crane like this one th-cam.com/video/C79Ejh4RfLs/w-d-xo.html and the last of the spoils with a clam shell bucket crane like this th-cam.com/video/GD-TQzdHbOU/w-d-xo.html
Hey Zep - some narration would've been really nice here. Some Qs: 1 - are the four retaining walls coated in concrete, what keeps them from collapsing? 2 - Around halfway point, those extended backhoes could no longer reach down below, so how did they remove this loose material? 3 - does anyone know why the Burrard Place Tower needed to go so deep for its foundation? 4 - How many dumptrucks did this require to remove so much material?
Drilled horizontal tie back rods and meshing and shotcrete (concrete spaying) - I missed that part, maybe clam shell bucket like this one th-cam.com/video/GD-TQzdHbOU/w-d-xo.html - Parking, 9 or 10 levels. - How many dumptrucks? Guess exactly right and win a condo suite in the building 😉
@@Zepfancouver I suppose one could work out how many dump trucks it took by knowing 1- how many cu yds each truck holds, 2- exact dimensions of pit. Relatively easy math equation.
@@brianbrewster6532 No, because you are implying every dump truck gets filled exactly the same amount every time.
@@jamestrotter7852 Nice, and you also assume many other variables, Math is amazing but the instant an assumption is introduce math is just a toy.

crazy
How do those dozers and digger buckets get out of the hole eventually?? This is amazing

I'm trying to capture an excavator egress, not easy, i get home from work and they're gone.
Surely they could use conveyor belts for the finer stuff!
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.
Nice swimming pool.
Surely they have heard of conveyors and cranes..
They're using a dredge bucket at a dig not for from this site th-cam.com/video/GD-TQzdHbOU/w-d-xo.html "Alberni by Kengo Kuma"
А ленту конвейерную поставить нельзя? Как на элеваторах
Almost reaching the earths crust lol
wondering if the walls are natural or did they make slurry walls prior to the excavation ? Anyone here know?
Has they dug down, drilled holes in wall for tie rods, installed meshing and shotcrete like this th-cam.com/video/o-6wNyYChV0/w-d-xo.html a site not far from here.
At about the six minute mark that bottom excavator started to remind me of the times I have tried to repair broken relationships.
Lol...Distanced and maybe a little out of reach.
@@Zepfancouver and still digging!

Very impressive, how come bigger machines weren't used ?
Lots of reasons, but one would have been limitations around removing the spoil from the site.
Wow.
