Here's an example of a freeway overpass column that was repaired after years of corrosion. All poured concrete, even the high end stuff on this building, has imperfections and will degrade to some degree over time. Someone posted photos of such imperfections about a year ago. I think the concrete on this building would be better with an outer coating.

^ I'm sure the concrete will be maintained properly. This is a $1 billion building where billionaires reside.

Paint serves no functional purpose and is a maintenance nightmare. Once a building is painted, it has to repainted every few years. This is quite expensive and is a completely needless expense.

Paint can also harm buildings. For example, painting brick can trap water and lead to rapid disintegration of the brick. Concrete is not affected in quite the same way, but it still traps moisture.

In my opinion, raw material is always better looking than paint. Exposed raw materials are typically used with expensive/durable material while paint is normally the cheapest option for covering up cheap material. While concrete is seen by some people as cheap, I view it as modern masonry and masonry should (almost) never be painted.

That's my opinion at least. I've seen far too many brick and stone homes around here ruined by paint. They become less desirable and eventually fall into disrepair. Long term, the raw brick and stone homes are worth much more.

When done properly concrete needs no protective coating. The pantheon is doing just fine after nearly 2000 years. In many instances applying an impermeable coating will actually shorten the lifespan of a structure.

Highway overpasses are not made of he same grade of concrete. It is likely the concrete for that column was poorly formulated or poured in bad conditions. If in really bad shape, a penetrating epoxy coating can be used to prevent further spalling. It is unlikely that the concrete work on 432 will be so badly done that it will crumble and require that type of treatment.

One can be sure, that on a building like this, especially one as costly and as prominent, that the architectural concrete for the columns and spandrel beams used will be of the highest quality. Concrete has been around since the Roman times, and has been improved with time. Degradation of concrete can occur with improper or inadequate concrete mix design (improper ratio of water/cement, admixture additions), inadequate cover of concrete over reinforcement, improper placement procedures, segregation of the aggregates, dirty water in the concrete mix, inadequate protection in cold weather (causing freezing), evaporation of the water in hot weather, among other variables.

As another person noted, the Pantheon in Rome is doing quite fine, thank you.

There will be no painting of the exterior of this building. Paint peels, degrades, and has to be renewed. Can you imagine repainting a tall structure like this? It would be impractical, first of all, and the cost would be prohibitive. Not to mention the safety of those performing the task. As defiler notes correctly, when concrete is done properly, no protection is necessary. Also, the highway requirements are somewhat different, in that the primary purpose is often just functional and structural, whereby 432 Park Avenue's exterior concrete is architectural as well as structural. The appearance of this ultra-luxury building on the Manhattan skyline is paramount. I am sure that the design mix was very carefully determined, and rigorously tested. In addition, each batch of concrete arriving at the job site is tested.

I have seen buildings with perfectly white concrete dating back at least 50 years that look fine without any glaring imperfections, I just wonder how different this concrete is to that kind.

How does this differ from other types building materials used? Bricks don't like vibrations and tend to crack. Glass and steel cladding need to be replaced afther 30-40 years because they look all worn out, their seals starting to fail, color loss, windows that become hazy....Synthetic, false concrete panels, thin layers of nature stone do even worse. They tend to come lose afther x years endangering pedestrians. Full nature stone buildings? Eaten away by sore rain that falls in our cities....

I wonder if it's possible to treat concrete with a transparent aquaphobic coating?

Even the billionaires that wind up residing here will not look as closely at the concrete (zoom lens within feet) as the twenty members that post here. Lol

After many days off, the 59th street cam is back in service, although the top of the building is currently out of view





But since it conserved the same position, it make it easy to do a gif with the progress of the last few weeks...

I have been very impressed with this project. Compared to One57 and 1wtc there have been minimal delays.

No está. No se como funciona eso, pero supongo que al estar todavía en construcción, no lo incluyen aún.

Esa información, todos los edificios en 3D, así como las imagenes satelitales, están alojadas en gigantescos servidores, y se cargan via internet al acceder a ellos, todo el que accede ve lo mismo. Es muy poco probable que unos lo vean y otros no.

Hola,
Puede descargar modelos 3D para usarlos en Google Earth desde https://3dwarehouse.sketchup.com/
Buscas por ejemplo '432 Park Avenue' y entras en la página del edificio, le das a descargar (download) y seleccionas el archivo KMZ.
Abres el Google Earth, vas a 'Archivo' -> 'Abrir...' y seleccionas el archivo descargado, y te llevará directamente a su ubicación.
Espero haber solucionado las dudas
--------------------------------------------------------------------------
Hi,
You can download 3D models for use in Google Earth from https://3dwarehouse.sketchup.com/
Search for example '432 Park Avenue' and enter the building's page, hit download and choose the KMZ file.
Open the Google Earth, go to 'File' -> 'Open ...' and choose the downloaded file, and will take you directly to it location.
I hope I have solved the doubts

I wasn't talking about other buildings. But to answer your question, the way this differs from other types of building materials used is that this one is concrete.
