Huge Retaining Wall Failure on My Toughest Building Site Ever
HTML-код
- Опубликовано: 3 окт 2024
- join me as I tackle my toughest building site ever, where we face a huge retaining wall failure on a steep site with a 17m height variation from the bottom of the road to the top. In this video, we’ll dive deep into the challenges of constructing a driveway retaining wall and building the foundations while dealing with a neighbour's failing retaining wall. Watch as we handle 3000 metres of steel and 64 cubic metres of concrete to stabilize this challenging building site. If you’re interested in construction, retaining wall failures, or building on steep sites, this video is for you!"

Nice to see someone in construction actually explain what theyre doing.
Wife and I looked at this section...... this video re-enforces our decision to not....
The owners must have literally won Lotto to build that, on that site..
Couldn’t imagine the cost of the siteworks
Good effort Josh! I hope the land was cheap!
Big fan of seeing the whole process of this build, you break it down so nicely 👍
Awesome stuff. This one definitely needs a cost summary of these different stages. This is not an untypical build for Wellington so it would be great that people have an idea of the actual "hidden" costs that go into builds like this.
Great job Josh just love your videos thanks for posting
We have those consents with disappearing and appearing features here in Blenheim.. Amazing what magic happens when a council employee moves into the street..
Keep up the great work!!
Cool to see Kiwis working with steel, I naively thought everything was timber framed out there 🙈.
well done on the project so far Josh. Looks like a logistical nightmare but you're tanking it.
Interesting that the engineering plans for the retaining wall specifically note "Existing Ground no slope" (@ 2:11) however there appears to be a very steep slope in front of the wall (@ 3:35) which will significantly reduce the capacity of the poles. I am surprised the inspecting engineer signed this off given this is noted on the plans.
I noticed that as well, not sure how this was signed off
Where the slope stops is treated as the start of ground?
Looks like a fun project to be on hopefully they got section cheap enough my god that's a lot of earthworks
the groundworks with the retaining wall probably cost more than the whole bungalow
Second floor stairs are fun to climb when some thing is forgotten
This land screams "land like this would never be developed anywhere else) so loud this has to be in Wellington
I now back up the comments I put on the first video. Who the hell would build on such a site and who the hell in council would approve it. Just look at the hill up behind it even.
Brave project, but that slab will likely stabilize the hill for all the neighbours. They should be thanking you.
The land would have to be cheap, because this build is going to cost a fortune. I hope the views are worth it. We have a section in New Plymouth, which sits on old swampy ground. Thankfully we bought it 25 years ago very cheap. There's an old house which we did up and got repiled, but there is enough space for another property, but it has to be compact and multi level. We had Geotech done and they said piles would have to go down 10m to the hardpan. We were going to build a modern Japanese themed townhouse over 3 floors, but the budget was 1M, so we sat on the idea. Now we are thinking of a multi level tiny home as an Air B&B. The plan is a 4.5 x 4.5m footprint over 3 floors with an additional 4th floor loft space. We can build up to 11m with a discretionary 12m maximum height, which means if we built this, it will be a mini skyscraper. The views from the top floor will be very good, but it's going to be interesting to see what an Engineer says. My Wife is an Engineer, but not structural. We might need some steel? Not sure? Maybe fine with 145mm thick studs, braced with ply and colorsteel on the outside. It's not going to be cheap, but it won't cost 1M.
Investigate hammering railway lines down the 10m. Cheapest way to go down that depth in either swampy ground or hill sites.
@@DiscoFang The geotech guy did say maybe it needed H beams. We have a high water table too, so drilling a hole will be like drilling a well.
@@JustyburgerYep lines are h or I beams. And you don’t drill, you drive. Could be done in a matter of days.
@@Justyburger40 years ago when I was first introduced to spec building, a mentor used used railway lines here on steep sites in Wellington. And I mean steep, not like Josh’s here. They were cheap, good quality steel, and again, cheap. I think they were 5 or 7m standard length, and you just weld another on as required until bearing resistance is met.
We are just about to start building on a slope this scares the shite out of me lol😂
I guess the membrane on the slope will eventually breakdown, unsure what happens then?
It takes a brave man to price a job like that.
Far out that looks expensive!
Great work! How did you get around not having a traffic management plan for the concrete trucks and construction work? I had to do a concrete driveway, literally had to block off the whole entire road for a 4 hr pour 🤔
Keen to know the cost. Looks so expensive D:
Is that Gary Dalton boring those holes?
why not do the retaining wall with poured concrete/rebar only. The beams seem like a very high cost
Few hundred k in ground works at least. Intense stuff an stressful build

How is the retaining wall up the back 10:22 youd hope thats been done very well!
Drilled into rock .... 🤣🤣🤣🤣🤣🤣
Braced all your retaining poles? Just call a pro😂
who came up with such a stupid idea to use wood instead of steel and concrete for this wall
I’m guessing these treated poles have proven themselves over time, to be ok’d by the engineers. After all, they use them a lot for house supports too, as seen in his other videos. Here in 🇨🇦, we tend to use those mega concrete blocks on engineered concrete footings, even the jumbo Allan blocks work too. 🤙
Cant you build concrete retaining wall
this does not look cheap. I am pretty sure that ground work will cost a bomb. I thought this look like Oriental parade or some where there is a sea view. I cannot see any. I cannot understand why the owner spend so much money on retaining wall to look at someone's roof top. I was wondering how much would the retaining wall cost? and where is the place?
