it is funny how we even think that a country that constructed the oldest wall in the world, a country that has been able to cater for the housing needs of its population of over 1.3 billion people, a country with the highest number of skyscrapers in the entire world will be erecting pre fabricated building here and there without considering so many factors. Very funny. Here in 9ja self, our local masons consider direction of wind in setting up certain things

The only thing why China things are cheaper is cos they are the master of machinery. They are very very advanced technologically.
Secondly, they don't pay much to their staff and lastly the most important one
they don't kill themselves with many laws and policies like the US.

Prefab homes are great but no one in the west will allow purely starked home up to 6 storeys simply because it's not safe to live in.

China and the Soviet build some of the shittiest construction, endangering the life of their people simply because regulations are non-existent in those climes.

When building a high rise, gravity load is a lesser consign than wind load and its effect on the building. How would a stalked building behave when the wind comes calling?

Laudbtc:
Engineers in the house, kindly help me review this estimate for electrical wiring because I feel it’s a bit too much

rationalmind:


The first video actually agrees with him. See the bolded part.

PS I did not watch the second

n3xt:


Chinese don’t have engineers. They only have shitty builders.

I’ll be following up this 28 hours build to know when it’ll collapse since it wasn’t build to Europe, US and naija building code.

I was hoping to see carpenters, iron benders, concreters working on the 10 storey building like we always do here

Why should China be assembly a house like cars? They still have a lot to learn.

In Nigeria, there’s always a problem for every solution.

Good morning!

Tiztonio:

Thank you sir for this in-depth quotation. Would help


Materials are too expensive here in benin. 16mm rod is being sold for 7700 naira

Greenarrow01:
Moreover China even built a pre cast skyscraper of 50 something storey building in 19 days. That's a skyscraper. They did it in 2015. People are still living there oooo wind no dey come that side. He dey run from them

Ok. I’ll suggest you read Precast Concrete Structures by Kim S. Elliott (2nd Edition) to get more info on precast structures built to Eurocode EC2.

I recommend the 2nd edition because it came with lots of updated researches.

You’ll also find in the book design exercise for 10 storey precast skeletal frame.

Im not so close to home, I’d have shared few pages from the book.

Don’t take me too serious though. I’m just advanced baba lat with lots of materials and books on modern architecture.

somehow:


People pay thousands of dollars just to go watch these engineering miracles.

7 out of the 10 longest bridges in the world are in China.

I bought a FULL 16mm rod for 8,000 naira in Ibadan.

Kudos to the seller, I have not seen 16mm that full before in these parts.

Badgers14:


8k for 16mm

Na wah, last I checked (sometimes early last year) it was 4200 or so.

I should have stocked up, by now I for don blow

But seriously though, things are getting wayyy out of hand now.

I wonder the audacity u use to type this flawed comment. You are so wrong. You really need to be englitened. Incase you don't know, the Chinese have the highest investment on research and development in the whole world. I have lived with the Chinese so I know what I'm saying.

Are we talking about completely stack modular homes here or bridges?
The two may involve a lot of structural engineering work but their performance and behaviour under loads are different.

n3xt:


Smiles.

You really need to go back and understand why I wrote what I wrote

It’s just a sarcastic remark. I know I am fantastically wrong.

Right here we were told Chinese build shitty structures.

In engineering there's what is called minimum and maximum stresses which a material can be subjected to before it can fail. Those materials used to install that building have been subjected to those stresses. I wonder why u stigmatized them. That's perhaps because u are short knowledged

abdulwastecx:


Precast concrete is different from prefab home. The video of the Chinese 10 storey building was made off modular materials, not precast concrete.

High rise building frames can be built with precast concrete, at least. The keyword there is frame and concrete.

You can't bring up a purely stack Chinese modular home without frames or shear wall as a Chinese miracle and turn around to change mouth to start talking about precast concrete. The beams of most high-rise building here in Nigeria are built with the precast concrete element. The girders(beams) of most bridges in Nigeria are built with precast concrete which can either be reinforced or prestressed concrete element. They do this because it is cheaper and easier to control the concrete quality at the beam yard.

"is your compound floor sealed" what do you mean sir?

Responding to the bolded.

Have you seen the firm’s proprietary Bcore stainless steel slab? I am sure it wasn’t used solely for aesthetics.

The modular units were built on the Bcore slabs.

———-

I tried looking up the company doing this amazing job, they’ve been round for a while now and have dozens of verifiable developments that have not fail or fall.

My apologies for the precast/prefab mix up.
Few pages back, I shared that precast is the future before the Chinese story came up.
