The RAUIE has prepared for you a review of 5 innovative building technologies that helped China take a leading industry position.
Top 5: "Green" concrete
Traditional construction in China does not stand still. Chinese researchers have developed a new type of concrete using natural soil. New green, low-cost concrete, developed by Xinjiang Communications Construction Group Co., Ltd's research team, also uses construction and industrial waste.
According to the company's report, a new type of concrete will help halve both the cost of construction and the construction time. It can be widely used in the construction of roads, railways and airports, agriculture, forestry, water protection, electricity and mining projects. The commissioning of a new type of concrete was planned for this year, however, due to the current situation, mass production will begin only in 2021.
Top 4: Bcore CTS
Technology that allows you to build multi-storey buildings in one night. Plate CTS (Core Tubular Stainless) is a strong building material, consisting of two panels, fastened with core pipes. The material is 10 times lighter than concrete, and its anticorrosion properties are 100 times more effective than that of carbon steel. This ensures material durability and earthquake resistance.
The technology was borrowed from the aviation industry, in which similar plates were used for the production of space capsules. However, in aviation, the plates had a honeycomb design, which made their production extremely expensive. In 2016, BSB found a way out, replacing the honeycomb with round pipes and significantly reducing the cost of production. In 2018, the company invented a unique furnace for mass production of CTS plates.
To date, BSB has put the production of CTS-plates on stream. In 2018, the company was able to build a 4-story residential building in just a night. The company later erected a 57-story building in 19 days. BSB is currently building the Sky City Tower in Changsha, China, which should be the tallest building in the world.
Top 3: Modular Construction
Surely many of you have heard of the incredible pace of building a hospital for coronavirus infected in China. The 1000-bed Hoshenshan Hospital was built in just 10 days. The unprecedented pace of construction contributed to the technology of modular construction.
The main feature of the application of modular construction technology in China is its integration into housing construction. The pace of urbanization in China is gaining momentum, so people need to be provided with housing as soon as possible. Modular hostels come to the rescue, which are built literally in a few days and provide thousands of citizens with housing.
Top 2: BIM Modeling
Building Information Modeling (BIM) not only allows you to build a building with minimal cost and in the shortest possible time, but also contributes to the effective operation of the building during its life cycle. When using BIM, a construction object is considered as a whole, and a change in one of the parameters entails an automatic change in the parameters and objects associated with it. In addition to the width, height and length of the building, BIM also optimizes the time, cost, environmental aspects and sustainability of buildings.
Despite the fact that China introduced this construction technology recently (in 2002, although the first use of technology in the world dates back to 1986), at the moment, China is a leader in the use and development of BIM. The technology allows you to create objects of complex design and shape, a proof of this is the Phoenix Media Center in Beijing. The outer shell of the center consists of 3800 glass panels of various sizes. In 2017, the building received the Outstanding Structure Award from the International Association for the Design of Bridges and Engineering Structures.
Top 1: 3D Printing in Construction
China was the first country in the world to use 3D printing technology for building construction. Many experts argue that in the future it is 3D printing that will become the main method of construction. Among the main advantages of the technology are speed, environmental friendliness, as well as minimization of costs.
The Chinese company Winsun uses recycled and industrial waste as the material for construction, while the cost of one five-story building with an area of 200 square meters is only 4800 dollars. At the moment, Winsun is helping to prevent the spread of the coronavirus pandemic: the company managed to manufacture 15 isolators for patients with COVID-19 with showers and eco-toilets in just 1 day.
The company keeps its technology in the strictest confidence: any shooting in the company's workshop (which, incidentally, was also done using 3D printing) is prohibited, a limited number of people have access to the printer itself.
However, it is too early to say that 3D printing will become the main construction technology in the near future. The printer can not yet produce complex architectural structures. Also, the cost and complexity of creating the printer itself remains a big problem. However, already now many countries are showing interest in this construction technology.
