Construction Speed of Fully Prefabricated Houses
The construction speed of fully prefabricated houses is relatively fast, with varying construction times for houses of different scales and types. Small houses can be built in as little as 2 hours, large villas in about 4 hours, and some high-end decorated projects take 7 days.
The construction speed advantage of fully prefabricated houses is significant, with its core lying in the factory prefabrication of components and rapid on-site assembly. Taking fully reinforced concrete prefabricated houses in rural Henan as an example, these houses use standardized components that are produced in the factory and then transported to the site for assembly through mechanized lifting and bolt connections. A few workers can build a set in just 4 hours. When construction speed is at its fastest, the main structure of a small house can be erected in 2 hours, while a large villa may take 4 hours. This efficient construction method benefits from the precise processing of components and the simplification of on-site operations, reducing the steps of formwork erection, concrete pouring, and curing in traditional cast-in-place construction, and significantly shortening the construction period.
For larger-scale and more functionally complex projects, the construction speed of fully prefabricated houses is also competitive. Taking a high-end decorated prefabricated house in a new energy factory in Wujin District, Changzhou, Jiangsu as an example, the project took only 7 days from foundation construction to overall completion. This indicates that fully prefabricated houses are not only suitable for the rapid construction of residential buildings but also meet the high time requirements of industrial buildings. Behind its rapid construction is a highly integrated design concept, where building structures, equipment pipelines, and decorations are pre-integrated in the factory, and only modular assembly is required on-site, achieving one-stop rapid delivery from foundation to high-end decoration.
Key Factors Affecting Construction Speed
The construction speed of fully prefabricated houses is influenced by component production efficiency, transportation conditions, and on-site assembly techniques. The automated production lines in factories can achieve mass production of components, but transportation distance and road conditions may limit the transportation efficiency of large components. In addition, the degree of mechanization of on-site operations and the proficiency of workers also directly affect the assembly speed. For example, using high-precision lifting equipment and standardized connection nodes can reduce on-site adjustment time, while a professionally trained construction team can complete assembly tasks more efficiently. These factors collectively determine the overall time from design to completion of fully prefabricated houses.
