Logic? Are you an expert in construction of super skycrapers or are you just guessing?

That's not logic. Some towers get the cladding quite early, some not.

, I know some towers get clad as early as the first floors shape up. But this tower in particular is not giving any signs that the cladding will start any soon.
That's just my opinion. We can't know what is behind the scenes after all.

hehe, I remember you said the first half of this year and that means before this July . We're almost in March now. But I hope your speculations will be just right. I want to see them starting it asap as well.

So still 4 months to go. I don't know if they'll start with the cladding until then, but i really hope it. And i think it's not impossible .

shoppingmall cladding begin.
shoppingmall will be open first at 2014

Nice render there inno. Didn't know there are earthquakes in Korea? To withstand 7.5 earthquake suggest is a very strong building.

You right Tandax
7.5 earthquake is very strong(guess even japan over 7 earthquakes is rare)
Seoul is pretty safe area from earthquakes.
Last earthquke in seoul was 6.0 at 1906

Magnitude means nothing for structure safety, as probability of hypocenter right underneath the building is 0,(0)%. 9+ intensity earthquakes happens relatively often in central and southern Japan. Last such wasn't that far away - just in 1995, in Kobe.

Built to endure wind speeds of 80 m/s? That is A LOT. A category 5 hurricane (basically as bad as they get) is usually around 70. And if my engineering knowledge isn't too far off, I'd guess that is what they set as the "base wind speed" to dimension the tower for. I'd say the structure itself is built to handle a fair bit more than 80 m/s.

Then again, that 80 m/s is probably only calculated to occur on the uppermost fifth of the building. Wind speeds increase with increasing altitude, so it's pointless to base the dimensions of the lower floors on the maximum wind speed 550 metres up in the air.

9+ intensity as in richter scale magnitude? The 1995 Kobe earthquake was only 6.8 magnitude and the March 11 2011 earthquake in Northeast Japan was 9.0 magnitude which was only one of five events thats ever recorded 9+ on the richter scale in the world. I wouldn't call that 'relatively often'.

Thanks for your concern

I heard HONGKON financial tower design endure 63m/s which completed in 1998(20mg peak that is 20years return typhoon wind speed)

So lotte tower probaly design endure for 80m/s(i heard from lotte tower exhibition center staff. If i'm wrong i will modifie data).
(Seoul annual average wind speeds is 30m/s)

Futhermore lotte tower designed with carbon structure for prevent total collapse when airplane crash to tower such like a 911.

Magnitude is magnitude, intensity is intensity.

There has been no 9.0 magnitude earthquake in Japan. It was deep in ocean, more than 100 km away from Japan. Magnitude can only be measured in hypocenter. Anything outside is shaking intensity. It was 7 to 8 in Sendai and 7 in Tokyo. 6.9 quake in 1995 caused more than 9 intensity along the fault.

Inno didn't specify 7.5 of what, but looks like it was magnitude that was meant. But building hardly withstand 7.5 if it strike right underneath it.
