html On June 30, Xintian Primary School in Caidian District, Wuhan City, Hubei Province was completed and entered the acceptance stage. The school was built by China Communications Construction Company No. 4 Harbor Engineering Co., Ltd. and is a Sino-French Wuhan ecological demonstration The important livelihood project of the supporting construction project in the eastern part of the city will be put into use in September and will welcome thousands of new students.It is reported that the supporting construction project in the eastern area of the Sino-French Wuhan Ecological Demonstration City is an urban complex project and is jointly developed by the CCCC Consortium in the "investor + EPC" model. This project applies the sustainable development technologies and experiences of China and France in the fields of urban planning, design, construction and management to the construction of a demonstration city. After completion, it will become an open platform integrated into the "Belt and Road Initiative" and lead the high-quality development of the Yangtze River Economic Belt. It will be a model new city for development and a beautiful window to showcase the achievements of "modernization, internationalization, and ecology" in the construction of Greater Wuhan, and create a model new city for the integration of Chinese and foreign cultures and a world model new city for sustainable development.

Implementing the "Two Mountains" concept to create a low-carbon demonstration city
CCCC Fourth Harbor Engineering Co., Ltd.'s construction includes 13 municipal roads, 4 schools, and 1 water system project, with a total contract value of approximately RMB 16 billion. Liu Zhenzhen, manager of the supporting construction project for the eastern area of the Sino-French Wuhan Ecological Demonstration City of China Communications Construction Company No. 4 Harbor Engineering Co., Ltd., introduced that Xintian Primary School is a "four-school co-construction" project undertaken by the bureau in the eastern area of the Sino-French Wuhan Ecological Demonstration City. One of the projects (Xintian Primary School, Xintian Middle School, Xintian High School, Tanghe Primary School), there are 24 teaching classes, which can provide thousands of students studying at the same time. This will further improve the local education environment and infrastructure conditions, and more It can well meet the educational needs of school-age students and the expectations of residents in the jurisdiction for high-quality educational resources.

On March 26, 2014, the Chinese and French governments signed the "Letter of Intent on Cooperation on the Construction of a Sino-French Eco-City in Wuhan", and the Sino-French Wuhan Ecological Demonstration City was officially settled in Caidian District, Wuhan City. According to the requirements of 3 years to form a prototype, 5 to 8 years to develop an image, and 10 years to be basically completed, efforts will be made to build a city of Sino-French cooperation, a low-carbon demonstration city, a city of industrial innovation, and an ecological and livable city. The accelerated construction of four schools including Xintian Primary School has become a microcosm of the implementation of this major plan.
reporters learned that in the construction of municipal road networks and campuses, builders implemented the sponge city concept, using permeable paving, and using sunken green belts on the side strips to store rainwater and provide road flushing and cleaning within 3 days. The amount of water used for greening irrigation will maximize the accumulation, penetration and purification of rainwater.
"The 'Four Schools Co-construction' project was designed by French architects. At the beginning, we deeply implemented the 'Two Mountains' concept, integrated design and construction, strictly abided by safe and civilized construction regulations, and formulated detailed We will adopt a standardized project management plan to continuously reduce pollution and add green," said Li Xiangqian, Secretary of the Supporting Construction Project of the Eastern Area of the Sino-French Wuhan Ecological Demonstration City of CCCC Fourth Harbor Engineering Company.
Prefabricated buildings Improve efficiency and save energy
Take out your mobile phone and "scan" the QR code posted at the construction site, and you can quickly check the key points of the construction process of each process. The QR code for technical explanations allows the project department to "live" innovative process training "stand up. Zhou Jun, chief engineer of the supporting construction project in the eastern area of the Sino-French Wuhan Ecological Demonstration City of CCCC Fourth Harbor Engineering Co., Ltd., said: “Based on the actual situation of the project, we also produced a QR code for technical explanations of masonry, plastering and other processes. It records the process flow and construction technology, allowing front-line workers to learn new process processes anytime and anywhere. "
In 2019, the country revised the " Unified Standard for Reliability Design of Building Structures" and set higher standards for construction projects. Prefabricated buildings have become a major trend and direction in the construction engineering industry. The builders of China Communications Construction Company No. 4 Hangzhou have adopted a large number of prefabricated building construction techniques in school construction. The assembly rate of the main structure of the school in the "Four Schools Co-construction" project has reached 50%. Among them, the constrained steel tube concrete prefabricated building and grid structure are used can effectively improve work efficiency, reduce the loss of wood molds, and reduce the use of steel bars.
BIM technology equips project construction with a smart "brain"
It is understood that the Sino-French Wuhan Eco-City project involves multiple majors such as housing construction, water systems, roads, etc., with multiple work stations running in parallel. At the peak of employment, there were nearly 700 workers on site personnel. In order to play the game of multi-professional and multi-work site construction, the project team made scientific deployments from the beginning, actively used BIM technology, and injected wisdom into the progress management and difficulty management of different work sites and different processes.
"The BIM smart operation and maintenance system of the supporting construction project in the eastern area of the Sino-French Wuhan Ecological Demonstration City of CCCC Fourth Harbor Engineering Co., Ltd. is a three-dimensional visual model built with BIM technology. It contains multiple subsystems and can realize visual management of the entire construction process." Teng Feng, safety director of the supporting construction project in the eastern area of the Sino-French Wuhan Ecological Demonstration City of CCCC Fourth Harbor Engineering Co., Ltd., said that this is equivalent to installing a "brain" that can perform intelligent analysis and provide intuitive solutions for building construction and operation and maintenance.
In response to the problems of large number of workers, scattered large equipment such as tower cranes, and increasing difficulty in safety management and control, the project team of CCCC Fourth Harbor Engineering Co., Ltd. fully used information technology and artificial intelligence to create a cloud data monitoring platform and smart construction site . It achieves real-time feedback on illegal operations of on-site workers and the working conditions of special machinery and equipment, and injects "smart chips" into project safety management.
