Prefabricated PC Assembly Houses in Baoding City

Baoding City has made remarkable progress in the field of prefabricated PC assembly houses, covering various aspects such as typical projects, technical features, policy support, and industrial development.

In terms of typical projects, the Anyue Jiayuan Community affordable housing project (Phase I) stands as a benchmark for prefabricated (PC) residential buildings in the Beijing-Tianjin-Hebei region. This project adopts a prefabricated assembled monolithic concrete shear wall structure, consisting of seven residential buildings with a total construction area of 73,750.03 square meters. Buildings 1 and 2 are 27 stories high, with the underground floor to the fourth floor above ground constructed using cast-in-place concrete, and the fifth to 27th floors assembled with prefabricated concrete components. The kitchen, bathroom, and decoration all employ prefabricated processes, achieving an assembly rate as high as 61%, ranking among the top in the country in terms of installation height and assembly rate. This project not only validates the feasibility of prefabricated technology in high-rise residential buildings but also provides a replicable technical model for the industry.

Regarding technical features, prefabricated PC assembly buildings achieve industrialization of construction by producing prefabricated components (such as beams, slabs, columns, and walls) in factories and then transporting them to the site for hoisting and assembly. Their core advantages include:

• Green and environmentally friendly: Reducing on-site wet operations and lowering dust and noise pollution, in line with sustainable development requirements;
• Resource conservation: Standardized production of components reduces material waste, and construction water consumption is reduced by about 60% compared to traditional methods;
• Quality improvement: The factory environment is controllable, with component precision reaching the millimeter level, reducing common quality issues;
• Shortened construction period: On-site operation time is reduced by about 30%, significantly improving construction efficiency;
• Labor optimization: Mechanized operations reduce reliance on skilled workers, alleviating labor shortages.

At the policy support level, Baoding City has issued the "Implementation Rules for the Management of Prefabricated Buildings", clearly stipulating construction proportion requirements:

• All newly built affordable housing and government-invested projects shall adopt prefabricated construction;
• Newly built public buildings shall, in principle, adopt prefabricated construction, with priority given to steel structures;
• The proportion of prefabricated construction for newly built commercial housing with an area of over 50,000 square meters in the central urban area shall be no less than 50% of the above-ground area. These policies promote the large-scale application of prefabricated buildings through a combination of mandatory and guiding measures.

In terms of industrial development, Baoding City has formed a collaborative model across the entire industrial chain, establishing nine component production enterprises covering categories such as concrete, steel, and wood structures, with an annual output value of 7.03 billion yuan, directly driving employment for over 3,700 people. As of now, the city has cumulatively constructed 11.624 million square meters of prefabricated buildings, ranking at the forefront in Hebei Province in terms of industrial scale and market application.
