The Wujiang COFCO Project of the East China Company of the China Construction Second Bureau adopts the prefabricated construction to unlock the "double carbon" password

Recently, a high-quality livable project in the Yangtze River Delta region with both international and regional characteristics, the project of the No. The project is located in Wujiang District, Suzhou, which is known as the "House of Silk".

The construction land area of the project is 38,447.1 square meters, with a total construction area of 97,052.19 square meters, of which the underground construction area is 26,903.3 square meters and the above-ground construction area is 70,352.4 square meters. There are 7 high-rise residences on the ground, and a parking garage on the ground floor. Different from the previous traditional construction operation mode, the interior wall panels and floor slabs of the project are assembled by prefabrication, with an assembly rate of 34.52%. From the source of construction technology, green energy saving and environmental protection are guaranteed, and new construction technology is used to drive the transformation and upgrading of the construction industry.

Prefabricated buildings help the "dual carbon" strategy

Under the background of the country's implementation of the "dual carbon" strategy, the construction industry is one of the important areas to realize the "dual carbon" strategy, and the prefabricated buildings are highly efficient and energy-saving, and the whole life cycle or carbon emissions can be reduced by more than 40%. It has become an important technical path to achieve "carbon peak" and "carbon neutrality" in the construction industry. As a construction project in the "dual-carbon" period, COFCO Wujiang project actively integrates the concept of green construction development, and makes positive contributions in reducing manual work, wet work, on-site work, improving project quality, and improving construction efficiency.

During the construction of the project, the prefabricated laminated panels and interior wall panels are uniformly molded on the production line of the prefabricated factory, cast and formed in a centralized manner, and transported to the construction site in the form of finished products. It only needs to be connected to the main structure through certain anchoring measures. One commander on site and three to four hoisting workers can complete the workload that required the same number of workers in three to four days in one day. Building a house in a "building block" style greatly reduces the labor intensity of open-air and manual work on the construction site, reduces carbon emissions during the construction process, and achieves both promotion and improvement of civilized green construction and cost reduction and efficiency enhancement.

High-quality assurance builds a livable life

The quality of buildings is closely related to people's daily life, and the quality of prefabricated buildings has attracted people's attention. Over the years, China Construction Second Engineering Bureau East China Company has been committed to the field of prefabricated building construction under the leadership of "Su Xianxin Labor Model Innovation Studio". Through standardized design, factory production, assembly construction, information management, and intelligent application, the appearance and use quality of the building have been greatly improved.

For example, prefabricated interior wall panels organically combine the installation process of lightweight partition panels with the material of aerated concrete blocks, which not only retains the material characteristics of lightweight infill wall masonry such as energy saving, fire protection, heat preservation, sound insulation, and durability, but also has the advantages of quick and easy installation on the construction site similar to ordinary light steel keel gypsum board and other lightweight partition walls. In the decoration and decoration construction in the later process, only a simple batch of putty paint can be carried out to achieve hardcover delivery, which saves a lot of decorative materials and eliminates the hidden danger of falling off in the later stage caused by the excessively thick decorative layer. The construction efficiency is more than three times that of traditional masonry walls, which greatly reduces manual masonry construction errors and human errors, and enhances the comfort of people's living while improving the construction quality.

Introducing the old and bringing forth new ones to reduce costs and increase efficiency

With the rapid development of cities, energy resources are becoming increasingly tight, the cost of living is gradually increasing, the concept of reducing costs and increasing efficiency, low-carbon cities, and green life is quietly sprouting.

While absorbing the prefabricated construction concept of the main structure, the project continues to explore and practice a series of prefabricated components such as prefabricated lintels, road substrates, waterproof sills, door opening reinforcement frames, and formwork for strong and weak electrical boxes. Actively promote innovative processes such as stereotyped steel molds and tooled templates that are vigorously promoted in the industry, while saving costs, effectively avoiding the dust risk of on-site construction, realize the concept of green management, and help the country realize the beautiful vision of green construction in which lucid waters and lush mountains are invaluable assets.

It is reported that the Wujiang COFCO project is scheduled to be delivered and put into use in April 2023. The builders are driven by "green + high efficiency" two-wheel drive, empowered by "low carbon + quality" dual-core, and ingeniously built to bring a new butterfly change to the Suzhou area, and will provide a high-quality livable environment for more than 600 families.
