A little about skyscrapers.
They talk and write a lot now about the fact that in our climate conditions, and especially in the absence of experienced specialists in Russia, it is dangerous to build skyscrapers.
But, for example, in Toronto, which is very close to us in climate, high-rise buildings are built perfectly.
There are also places with much more difficult conditions: seismically active Japan, Singapore, where it is necessary to drive 200-meter (!) piles for the soil to withstand (by the way, we only use 30-meter piles), the Emirates with their sandstorms and wild heat.
And similar construction is going on everywhere.
As for the skyscraper «Federation», from the point of view of «physical life» this skyscraper will stand for more than 100 years.
It is taken into account that the condition of the structures and engineering systems will be constantly monitored.
But this period is much longer than the «moral» one: when the tower is finished, it will inevitably become a little outdated.
All that can be done is to try to level out this process by making changes during construction.
The construction of «high-rises» is a kind of technological challenge.
In accordance with Russian state standards, they are classified as structures of the first level of responsibility, which means they require careful consideration at the design stage.
Until recently, one of the main problems of high-rise construction in Russia was the lack of building codes and regulations for buildings taller than 75 meters, which is why each high-rise project required individual approval from many institutes (Research Institute of OSB, Federal State Unitary Enterprise KTB ZhB, GSPI, Research Institute Mosstroy, FAPS (Rostroy), which increased the cost of construction and its duration.
But now we can breathe a sigh of relief: last year, the regulatory framework for high-rise housing construction, which had been developed over several years, was finally approved.
As officials explain, this process was delayed because the framework itself is very complex; many specialists were involved in its development, who “honed” the sections of this document in detail.
Moscow stands on fluvioglacial sands and clays, and a number of experts categorically advise against building heavy buildings on them.
This is not New York or Kuala Lumpur, which are firmly established on rocky ground. The mass of even the smallest Moscow high-rise is 150,000 tons, and it is unknown how the soil will behave in 10-15 years.
However, in fairness it should be noted that the construction of 60-story skyscrapers in Singapore, erected… in the middle of the ocean, and Las Vegas, which grew up on the sands of the Nevada desert, and the «high-rises» of Monte Carlo, built on the water, have been thoroughly criticized.
In response to such attacks, other experts say that although Moscow land is not the most ideal site for construction, it is quite possible to work on it.
You can build on almost any soil, if you do it correctly.
In other words, the problem is not in the soil, but in the qualifications and integrity of the builders.
