Really love these videos especially how Stuart has made an effort to visit Abu Dhabi in order to make the video, that's dedication 😄
It must have been a great sacrifice to stay in a 5* hotel. That's dedication to the channel right there 🤣
Abu Dhabi
oh yeah I've corrected it lol
I hope you expensed the hotel and bar bill 😊
Life is hard as a RUclipsr 😜
Guy came out of nowhere and starts making 10/10 videos. Love it.
His other channel has 300,000 subscribers, but I completely agree; these videos are amazing.
@@JLL12345 i knew i had seen him somewhere
@@JLL12345 property diy, proper Dubai, proper engineering.
I really appreciate the work that went into that model. Great job!
Thank you very much!
Really interesting! Also I genuinely chuckled at the "1 hotel" unit joke 😄
Glad you liked it!
This new Proper Engineering channel is Proper Interesting
Thanks!
Another brilliant video. I wish you were my lecturer when i studied engineering in college, i might have actually learnt something 😂.
Wow, thank you!
I've been waiting for this upload Stuart,
I cant believe the engineers knew how much the central column was going to tilt, so built it on a wonk from the beginning, that's just amazing 👏
Thanks Stuart. Fascinating structure…especially given the soil conditions. Also a great explanation! Cheers
I think that you possibly overlooked the fact that the swimming pools, situated at roughly half way up are on the opposite side of the lean, and so their weight is also acting as a cantilever, also aiding in the stability of the building.
I’m afraid Im the design you cannot assume the weight of the swimming pool will help balance the building in your calculations. Simple reason is at some point in the future the pool will be drained for refurbishment/repair and the building still needs to be structurally sound during that period.
Fascinating stuff. I'm enjoying this channel as much as Proper DIY.
Glad to hear it!
I love how your videos keep popping up for me, proper quality for such a new channel
I’ve always had an interest in engineering and architecture despite knowing very little about it. Love these videos Stuart, it’s like revealing the secrets of the magic circle!
Thanks Leo!
Can't wait to see you build a multi story leaning extension to your workshop Leo.😀
Paul, your knocking it out of the park with these videos. Thanks for making us aware of the modern miracles that are in plain sight, that we -sometimes; don't even spot.
Glad you like them!
Very cool. This new channel is fantastic! I saw where your three lifts video got a shout out in Tom Scott's newsletter last week. Well done!
Awesome! Thank you!
Your "rough and ready" models/visual aids are amazing!
Great stuff Stuart, even with having been in structural steelwork for 42 years I love these videos, makes a massive change from portal frame buildings, schools etc that we build week in week out.
If you ever want to visit a fabrication workshop I am sure we could fit you in.
Regards
Steven
Glad you enjoyed it. I may take you up on that - at some point in the future I will be doing a video on steelwork and it would be great to get good footage of real fabrication etc.
Loving these video's Stuart. Another informative and interesting insight. Thank you.
Glad you like them!
Great video. I lived in the UAE for 7years and never failed to be amazed by the variety and complexity of the buildings that were constantly being built.
To the west from Abu Dhabi my guess would be it was built leaning towards Mecca. What a nice touch.
I spent 18 months in Dubai living there. It was a mistake. I should’ve lived in Abu Dhabi instead. Much more civilised place. Wonderful wonderful architecture. The Sheikh Zayed mosque and the Louvre in particular are just absolutely out of this world.
When they built the Humber bridge the towers were built looking in so the weight of the bridge sections pulled the towers level.
Why was civil engineering never mentioned whilst I was seeking career options at school? It is truly fascinating. Thanks for the insight.
Fascinating and very interesting. Thank you.
Love these engineering explanation videos,, there are a lot of blokes who don't understand engineering, these really inform and entertain
Another excellent video. Thanks for all the work you put into them.
Excellent, and superbly explained !
I come for the research, model building, great dialogue and un intimidating explanation for the interested layman.... went away very happy... thank you sir.
Glad you enjoyed it!
That was fantastic, really enjoy the miniature models! Makes a change from the ubiquitous 3d animations on 99% of videos.
Thank you very much!
Another great video Stuart. Thanks
Thanks 👍
Fantastic video !!! thank you Stuart
Glad you enjoyed it
I’m loving this new channel, it’s fascinating stuff. Thank you for sharing
Glad you enjoy it!
Class as always Stuart.
Really great video Stuart, very interesting and well presented, I really love them. 2 other thoughts, I'm so glad that the wonky brush (I think you said that's the correct engineering term) the finest that Poundland could sell, didn't make it over from your other channel. Also you could in due course start a 3rd channel showing Archetectural models 101. Terrific content please keep it coming.
Glad you enjoyed it
I absolutely love this channel, top notch content
Another excellent video. Thank you Stuart!
Glad you enjoyed it
Brilliant video!
Glad you liked it!
I’ve worked in Engineering since I was 18 I am now 55. I just love the technical stuff. We can do anything if we want and have the money. Sometimes I have to say to my colleagues, think if it is necessary before you do it. What return are you going to get for what you want to do? Great video and fantastic explanation. Thank you.
I guess for the next one you could talk about Blatimore bridge?
Love the new video series. Was there in November, they just love tall/ unique buildings
Now I know why my Jenga Towers keep falling over. Not enough friction or mass in the foundations. And all them triangles on the outside too! 🙏🏽
A brilliant explanation as always Stuart and yet again a superb model.👍
Glad you enjoyed it
Excellent....never too old to learn. 👍
Another super video thanks Stuart
Glad you enjoyed it
I only came across your channel a few days ago, and I have to say I love the style of video / the info etc.. I am finding some of the usual engineering channels I usually listen to are starting get a bit subscriber based inflated ego syndrome. Subscribed! 👍👍
Welcome aboard!
That’s definitely dedication to duty to travel to Abu Dhabi for a RUclips video! Interesting building I didn’t know existed. Thanks Stuart for your sacrifice and sharing your knowledge.
Thank you very much
Fascinating. Loved it.
Great video Stuart. Very informative in terms of tourism and structural engineering 👍👍
Glad you enjoyed it
similar designed in lean as the Leadenhall Building except that is not about overhangs but I think was the wind and floor loadings
Thanks Stuart!
loving this channel! how interesting
Great video, Stuart.
Many thanks!
Wonderful video! I really appreciate your analysis of the engineering but I have a hard time appreciating the aesthetic 😂
so thats what its called, interesting. nice one steve
Even if I don't understand everything... I really enjoy seeing and finding out about these buildings you show us. They are always interesting and you do explain it all very well. 🥰
Glad you like them!
Thanks Stuart, another interesting and entertaining tour and explanation, another great model too !
Next engineering question, how is that large water tank supported in the loft of your out-building and how will you get it out ? 🤔
Your new channel is absolutely wonderful.
I enjoy(ed?) Proper DIY, but that was from an "OK, that's good way to do." perspective.
This is opening my eyes to new concepts. Thank you.
Thank you very much!
Best channel on youtube.
Now this is the best comment I’ve ever had!
I was involved in an exhibition at ADNEC in 2011 and had to visit the construction site for Capital Gate a number of times. At one point I was taken up to the helideck and that was quite thrilling. The Project Manager did say they had pressing deadlines and the response of the Emiratis to problems was to throw money at it so in the relatively small site, there were over 1500 workers. Quite how they didn't constantly bump into each other I don't know.
Great video Stuart, very informative. Your model is impressive and certainly helped us understand the design techniques involved👍
Glad it was helpful!
So the two rumours that I was told about this building were firstly the football stand is integral to the construction as a counter weight to the lean, secondly they had all but finished the building of the building and sheikh Khalifa said but where will my helicopter land and the pad on the top was very much an afterthought and when they put it on. The engineers couldn’t prove that it wouldn’t topple the building, but it didn’t, but also no helicopters land on the pad.
One other thing is you had a great view of the US embassy from your bedroom.
1st one - not true. 2nd one - true. You will notice the helipad is still directly on top of the core which helps a lot.
I was completely unaware that "wonk" was an engineering term. I have been using engineering parlance for years, and didn't know.
That's an incredible building. Building the core on the 'wonk' (engineering term 😉) is very interesting. I wonder if the engineers just kept adding floors until it was straight or were the initial calculations spot on and 35 floors was the original plan? 🤔
I used to work in one of the teams that looked at this. I understand that the straightness of the lift (elevator) core was a key issue - if the weight of the building pulled the core over too much then the lifts wouldn't work.
The calculation of the amount that you have to build the thing out-of-plumb is complicated by the fact that concrete actually shrinks over time. The amount it shrinks depends on a lot of things, including how fresh the concrete is when load is applied to it. The calculation did represent the building being built floor-by-floor, in order to get as good a feeling for how out-of-plumb to build it.
I've not heard of any complaints, so I guess it must have been close enough.
Good insight
@@properengineering, thank you. Thanks for putting up videos that go into some of the technical aspects of these things so clearly.
Brilliant Stuart!👏
Thanks
Excellent
Thanks
After Tom Scott's retirement due to old age, this channel appears to be a proper successor.
Really good video, thanks!
Glad you liked it!
Excellent video Stuart - and, a nice holiday for you too 🤣
Another great video
Glad you enjoyed it
Interesting stuff Stuart! Looking forward to more of these videos!
If I may ask: do you travel to the UAE for yourself, or were you there for business? I'm asking because I wonder how one would end up there 😄
Very interesting. I have no connection to engineering whatsoever. But I enjoy listening to you explain these things. I like your other channel as well.
Thank you very much!
Well done Stuart. 👍🇺🇸
Thanks
How about your take on the "Cheesegrater", The Leadenhall Building? That would make an interesting vid. No concrete core there!
Superb! Nicely done Stuart. Does this building use the space in the lattice for cooling, like the one at 80 Canon St, in your previous video?
Really enjoyed this video Stuart, thank you very much. So on a slightly different engineering theme I found myself pondering what I shall call "Big sticky uppey towers" and there different methods of construction. EG - St Johns Beacon (Liverpool) CN Tower (Toronto) appear to be self supporting or free standing. As opposed to the Centre Point Tower (Sydney) and the Space Needle (Seattle) which appear to need external bracing and I wondered why ? my guess is weight and winds but I was just a mere Bus Driver so I know nothing really.
You get the choice of internal or external structural elements. The external ones are visible and more susceptible to corrosion and fire, the internal ones cost you floor space and flexibility.
You would have been a great teacher. Maybe you'll get some guest lectures out of this!
Great video again, what’s next? Can he top it? Thanks Stuart 👍😃
Superb insight, are you going to build one of these in next weeks Proper DIY 🤣🤣
I'm afraid I think I've already spent enough time on this building as it is!
Does the building move in high winds atall Stuart??? Not sure I'd enjoy those floor to ceiling windows on the overhanging section if it was moving around too. I read they adapted floor to ceiling glass in Trump Tower after people found it too stressful when it first opened. I guess cutting edge engineering can clash with people's tolerances at a certain point.Thanks I found it most interesting.
I’m sure it does move but probably less than is noticeable - there is a limit in the design codes which they need to be under.
Great video, but I wondered if there was also some element of stability due to the fact that the centre of gravity of the structure is still above the foundation?
Amazing video as always, mate. I chuckled at the hotel units LOL. Bold of them to rely on piles-in-tension. What happens if an earthquake hits and the dessert sand is liquefactioned? The thing start leaning an ungodly amount??
Anothwr fantastic video.
Glad you enjoyed it
Its a bit like the "geodetic" framework of the old Vickers Wellington Bomber. Real clever engineering.
Yes very similar
It all must depend on research and development, so when such activity exceeds such parameters then obviously we enter a different outcome . There is obviously no reason to explore such outcomes . But human nature being what it is , it’s inevitable that such boundary’s will be pushed .
It will look good once the scaffolding has been taken down !
Another excellent piece of information. Did the video come about from a holiday or a holiday because of the video?
I was working there
Great video. Unusual fact, you can watch The Flintstones in this hotel, but not in the other emirates, because they don't like the Flintstones but the people in Abu Dhabi Do!! (Couldn't resist, please don't unsubscribe me!!)
😂🤣🤪👍
Pretty sure 1 hotel is equal to 4 house! Or did my childhood lie to me
Stuart, what is the scaffold-like structure draping the non-leaning side of the structure? Is it structural to the main tower? Thanks for your interesting video.
who cleans the windows ?
WOOW stunning video cheers ,,what is your trade m8 ?
Civil Engineer
i dont know mate, maybe they calculate it so it fkin stands and not falling
Are the diamonds on the Hancock Center in Chicago also a DI grid?
I guess there are no pianos in the hotel rooms
I hope you expensed the hotel and bar bill 😊
Of course
"wonk" - LOL
Any American viewers would possibly have laughed at you "knocking up a model"😂
So they don't just counteract all the forces by filling the swimming pool with heavy water then? 🙂
I’m afraid you can’t use the weight of the pool to help the overturning calculations in case at some point in the future the pool is drained for refurbishment/maintenance.
i sense in the 70's 80's before all this computer stuff, you would have been a top after dinner speaking draw
But why?
Why go though all this complexity and cost to build yet another over the top Arab hotel?
There are no space constraints, line of sight or air rights issues.
If the owners were real businessmen they would keep controll of costs and build an extravagant hotel upright.
Amazing what you can do with CAD, engineering nous, and some slave labour.
😄😄 Wonk
