Entering Chinese Architecture: "Witness" China's Speed, Prefabricated Buildings Promote Green Development

Under the major examination of the epidemic, the Huoshenshan Hospital was built in 10 days and the Leishenshan Hospital was built in 12 days. China State Construction Group Corporation (hereinafter referred to as "China State Construction Group") has created a world-renowned "China Speed".

At the end of the big test, China State Construction Group actively participated in the construction of the project to "make up for shortcomings". Its China Construction Third Bureau undertook more than 10 Hubei Ping-Eye Integrated Hospitals, and the service was revived after the epidemic. Strengthen scientific and technological innovation, promote "green construction, smart construction, and construction industrialization", China State Construction Group promotes the green development of the industry.

Recently, a number of media groups followed the network communication bureau of the Central Cyberspace Administration of China and the State-owned Assets Supervision and Administration Commission of the State Council.

China State Construction Group was formally established in 1982. It is one of the investment and construction groups with the longest professional development in my country, the earliest market-oriented operation, the highest degree of integration, and the largest scale in the world. In China, China State Construction Group has invested in the construction of more than 90% of skyscrapers over 300 meters, three-quarters of key airports, three-quarters of satellite launch bases, one-third of urban integrated pipeline corridors, and one-half of nuclear power plants. One out of every Chinese uses a house built by Chinese architecture.

From "Shenzhen Speed" to "China Speed"

In the 1980s, during the construction of Shenzhen International Trade Building, the tallest building in China at that time, the China Construction Third Bureau under China State Construction Group innovatively adopted the unprecedented large-area internal and external cylinder synchronous hydraulic slipform construction technology, which greatly improved the construction efficiency and speed, creating the "Shenzhen Speed" of three days with one building.

On January 23 and 25, 2020, when the Wuhan epidemic was raging and a special hospital was urgently needed to treat patients with new coronary pneumonia, China State Construction Group successively received the construction tasks of Huoshenshan and Leishenshan hospitals.

The Party Group of China Construction Group issued a mobilization order to the whole system as soon as possible, and played the main role in the Third Bureau of China Construction Group. The 11 subsidiary companies are rushing to the Starry Night, and 40,000 builders will fight in Wuhan to give full play to the world's leading construction capabilities and the advantages of the entire industry chain to quickly build an efficient and sound on-site management system. Formulate "hourly" combat maps, widely apply advanced technologies such as building industrialization, and promote project construction with high quality and efficiency.

In the construction of the Huoshenshan and Leishenshan hospitals, China State Construction Group has given full play to its advantages in the entire industry chain and supply chain. More than 2,500 large equipment and transportation vehicles, more than 4,900 containers, 200,000 square meters of impermeable membranes, as well as a large number of cables and wires, power distribution boxes, sanitary ware and other materials arrived in Wuhan in just a few days to provide a guarantee for the overall acceleration of hospital construction. In the end, the Huoshenshan Hospital was built in 10 days and the Leishenshan Hospital was built in 12 days, creating a world-renowned "Chinese speed".

Regarding the construction of Vulcan Mountain and Leishen Mountain Hospital, on January 31, 2020, at a press conference in Geneva, World Health Organization Director-General Tedros said: "I have never seen this kind of mobilization in my life."

From February 4, 2020, the Vulcan Mountain Hospital admitted the first patient, to April 15, 2020, the Huoshenshan and Leishenshan Hospitals were closed. The "Two Mountains" Hospital has cured a total of 4,879 discharged patients. They has made outstanding contributions to Wuhan's fundamental transformation from "people waiting for bed" to "people waiting for bed" and achieving major strategic results in the fight against the epidemic.

It is understood that since the fight against the epidemic, China State Construction Group has built 119 medical facilities across the country to provide a strong guarantee for the prevention and control of the epidemic.

Carry forward the "spirit of fire and thunder" to help Wuhan's public health system "make up for shortcomings"

In the post-epidemic revival, the Hubei Provincial Government issued the "Three-year Action Plan for the "Ten Major Projects" for Reinvigorating and Reinforcing Shortcomings after the Epidemic, ranking the public health system to make up for the shortcomings project at the top of the "Ten Major Projects". China State Construction Engineering Group is actively involved in the construction of the project to "make up for shortcomings". Its China Construction Third Bureau has undertaken more than 10 Hubei Ping-Eye Integrated Hospitals, including 4 projects in the Wuhan Public Health "Four Districts and Two Hospitals" project. Yunjingshan Hospital is the largest hospital among them, and local media call it the "permanent version" of Thunder God Mountain Hospital.

According to reports, Yunjingshan Hospital has a total construction area of 252,500 square meters, with 1,000 beds and 1,000 beds reserved for construction. After the project started in November 2020, in the face of a 245-day tight schedule, more than 3,000 builders carried forward the "spirit of fire and thunder". 200 managers and 1,300 workers celebrate the New Year on the spot, and work does not stop during holidays.
