Miami’s First Supertall Tower Breaks Ground The 100-story building requires special foundations and a pendulum-like device to prevent swaying
Wall Street Journal ^ | 11-1-22 | Deborah Acosta

Miami’s Waldorf Astoria residential tower, poised to be South Florida’s tallest skyscraper, is a test case for new techniques meant to enable the more than 1,000-foot tall building to withstand hurricane-force winds and remain stable near sea level.

Developers broke ground on the building’s foundation in downtown Miami in October. The 100-story tower, which resembles a series of glass cubes stacked on top of each other, will feature 205 hotel guest rooms and 360 luxury condo residences. It would be the city’s first supertall structure, and the tallest residential building south of New York City when completed around 2027, according to the development team.

Supertall towers, which architects tend to define as buildings that rise at least 300 meters, or 984 feet, have been common in cities such as New York and Chicago. But no one has succeeded in building one in Miami.

That looks like a sheetrock screw

Not giving a CC to read the story…

What is this “pendulum like device”?

How does it work?

I think the city water is potable.

I inspected all the rebar, concrete and post tension cables on a 17 tall floor concrete courthouse building with no sheer walls, it didn't stop swaying until around the 14th floor when the giant Showa shock absorber sway braces were installed.

some of the workers were getting seasick. There were some weird things that didn't make sense to the workers that I had to enforce for the design engineers who stayed in daily contact with me. For example, things like 5000 psi concrete in the perimeter columns but 8000 psi on interior columns, I had to watch closely and tell them no, "I just talked to the engineer and was you can't put that 8000 in that column"

If I wasnt there every minute it would not have been built anywhere near as engineered

WTF!? Is that what it is supposed to look like?

It’s typical “look at me” architecture that’s rampant today. Just designing something different to get attention, with no consideration of art or beauty. It’s the same sad state that “art” has been in for a long time.

It looks like the architect spent all of a few seconds with his kid’s blocks to come up with this non-design.

Surprisingly the structural engineering is not generally the divider between success and failure of structures like this.

The temptation to make a “Statement” or create a “surprise” is the big problem. The designer comes up with weird shapes (like the box stacK) or the gee-whiz skywalk at the Hyatt Regency that had a disaster 35 years back and the design team can’t handle the little details for execution or frivolous things like water tightness or foundation execution.

In my opinion as a former builder, Frank Gehry is one of the biggest offenders in this category. Look up a list of his buildings or failures. Law suits for decades.

The builders of the Titanic said it was a ship,that would never sink. We know how that turned out.

Here is one that has been on/off again for ten years in Chicago.

That’s a Santiago Calatrava design. He’s both an engineer and an architect, so his designs are spectacular, but he’s a one-trick pony. All of his buildings look very similar.

sometimes they dont get built as designed and little details can make a huge difference. For example, properly encapsulating the post tension tendon ends on the outside edges of the building gets left behind, (because it is very difficult hanging off the side as access disapears then it gets covered with cladding ), eventually the wedges rot and let go . So many times I had to build the case, prove the tendons werent properly capped, convince management it was a critical safety item and follow it through to completion

Somebody got the idea for that building design, from watching a 2 year-old stack letter blocks.

Hurricanes will divert themselves after seeing how easy it would be to knock those boxes down. Al-Qaeda and the Taliban would not even bother to fly planes into that building, expecting that it would collapse on its own sooner or later.

Science denier! And that whole sinking story is misinformation.

They didn’t build it to Florida code.

No worries. Only the first floor will be affected.

Miami and many coastal cities are experiencing salt water intrusion. A serious situation for sure.

Thanks. Nearly went into that field fifty-five years ago, but....

Problem with Titanic was they did not watch for icebergs which ar eknown to frequent in north Atlantic.

But more serious problem was there were not enough life boats for all aboard. Now the maritime law requires all cruise ships must have enough life boats for all passengers and crew aboard.

WHich is why I am booked on my 48th cruise in January 2023.

South Florida high rise condo? Anyone ever hear of Surfside?

Maybe they can get the engineering team that did the bridge at FIU.

Sure.

And the Titanic was unsinkable, too.
