Prospectives of Constructing the Tallest Buildings: Beyond the Vertical Race Since the beginning of the 21st century, humanity has experienced a true revolution in tall building construction. The Burj Khalifa (828 m) in Dubai, the "first kilometer skyscraper" Jeddah Tower (1008 m, construction suspended), marked new technological and ambitious horizons. However, it is now obvious that the era of simple pursuit of size is coming to an end. The prospects for constructing the tallest buildings are no longer determined by the question "how high?", but by more complex challenges: "why?", "how sustainable?", and "at what cost?". Economy and symbolism: from prestige to utility Initially, ultra-tall buildings (over 300 m) were symbols of national or corporate prestige, "vertical visiting cards". Today, their economic model is being questioned. The cost of construction grows disproportionately with height due to difficulties with foundations, wind loads, logistics, and life support systems (elevators, water supply, evacuation). The key indicator — the ratio of leased area to total cost — turns out to be inefficient for many ultra-tall buildings. The future, perhaps, lies in mixed-use (mixed-use). The tallest buildings will not be just office towers, but vertical cities that combine residential apartments, hotels, offices, shopping galleries, cultural and recreational spaces. This increases economic sustainability and social dynamics. An example is the Shanghai Tower (632 m), where, in addition to offices, there is a hotel, museums, and observation decks. Technological breakthrough: new materials and "smart" systems Further growth is impossible without innovation: Materials. Concrete and steel have reached their limits in terms of strength-to-weight ratio. Prospects are linked to carbon fiber, graphene composites, and ultra-light metal alloys. Experiments with self-healing concrete containing bacteria that "heal" microcracks are already underway. Constructive solutions. T ... Read more
