Another milestone for the prefab construction industry will be attempted by Broad Group, a Chinese Construction Company. The company will attempt to build the world’s tallest skyscraper in as fast as 90 days! The skyscraper, “Sky City One” will stand 2,750 feet (838 meters) and will take 1/12 of the time that the world’s current tallest building, the Burj Khalifa, took. Sky City One will be 33 feet taller than the said building. The secret behind the rapid is prefabrication. Before construction on site even begins, 95% of the building will have already been finished.
Broad is also the same company that built the New Ark Hotel—a 15-story building that only took a week to build. The same modular and prefab construction principles were applied to the hotel building. Taking from its success with the New Ark Hotel, Broad will now attempt to construct a 220-story skyscraper that is supposedly able to withstand a magnitude 9 earthquake.
Broad further says that Sky City One is earthquake resilient and can accommodate as many as 100,000 people. It will also have leisure and retail facilities. The 220 floors will be connected by 104 elevators and will cover a total of 10,800,000 sq ft of usable floor space. As for its energy consumption, the skyscraper will consume only 1/5 of the energy of a usual building, thanks to green practices that will be applied. This includes thick quadruple glazing and thick exterior wall that will increase the interior insulation of Sky City.
And the cost of Sky City One? The estimate is around $628 million. That is a lot cheaper compared to the $1.5-billion Burj Khalifa.
The plan to launch Sky City One is a commendable effort to put prefab buildings at the forefront of the construction industry. After all, it highlights everything that’s positive about prefab buildings: economical, inexpensive, fast, and durable.
