Watch: 10-storey building constructed in China in just 24 hours, here's how

After hitting headline in 2011 for construction of a 15 story Ark Hotel in Changsha in just 46.5 hours, a privately owned manufacturing enterprise in China, Broad Group, has done it again. This time, it has developed a 10-story apartment building in just 28 hours and 45 minutes in Changsha, China. firm, Broad Sustainable Building has been expanding  architecture, engineering, and construction (AEC) industry by using  installations of prefabricated, factory-built structures that are mostly shipped in 3D forms as foldouts. Even n, to construct 10-story residential high-rise in such a short span of timeframe required company ample manpower, at least three cranes, and a large number of builders on site to get structure standing. 

In time-lapse foot that company shared on its website as well as social media handles, its on-site crew is seen cutting a new edge in of industrial invation by constructing a 10-story steel apartment building in just over a day. This obviously was made possible after China-based enterprise bolt-toger modular units kwn as “Living Building System”. 

broad group used pre-manufactured components, including walls, kitchen, bath, and floors that are folded out to a span of 39.3 feet by 15.75 feet by 9 feet high and are n able to fit into a standard shipping container to be transported to construction site where it is assembled. Although, assembling a building this tall, even when 3D components of buildings and mechanical systems are all in place can be a tough feat, as can be seen in nearly 5-minute foot shared by group. 

Board explains techlogy on-site, saying that ahead of construction, floors, walls, windows, and glass; electrical and mechanical equipment; AC and DC power, lighting, water supply, and drain; as well as sanitary facilities, are all completed in factory using pre-construction and conceptual design process. company’s 5D Macro-BIM helps preassemble at least 95 percent component reducing work at construction site to “minimal.”

In factory, engineers connect bolts, pre-ready water supply, drain, and electrical systems so that structure can be occupied immediately. Broad constructs walls out of CTS Slab panels, which are stainless steel with bending rigidity. parametric building components are also cost-effective.

'Extremely simple onsite installation..' says company

In video, Chinese-based group explains, “extremely simple onsite installation” — just tighten bolts and connect water and electricity”. company also claims that it has tested its construction methods to withstand earthquakes that measure 9.0 on Richter Scale despite its speedy build time. components carry a longer life span and recyclability. panels can last thousands of years and building itself can be "disestablished" and moved or taken somewhere else. In 2010, Broad group used its invative construction methods and environmental-friendly techniques to build pavilion for massive Shanghai World Expo.
