Prefabricated House Economic Utility
The economic utility of prefabricated houses is primarily reflected in aspects such as cost, construction period, environmental protection, quality, and service life.
Significant cost advantages: In European and American countries, the labor costs for traditional construction are exorbitant. Taking the United States as an example, construction workers earn at least $200 per day, with skilled workers earning up to $500. Additionally, there is no overtime culture, resulting in a combination of labor and material costs that make the construction of a single house cost at least one million RMB. In contrast, a prefabricated house produced in China costs only 200,000 RMB per unit, offering extremely high cost-effectiveness. In rural areas of Henan, China, the cost per square meter of a prefabricated house is just over 300 RMB, highlighting a significant price advantage.
Substantial reduction in construction period: Compared to traditional construction methods, prefabricated houses significantly shorten the construction cycle through modular production and on-site assembly. For instance, a real estate project in Shanghai adopted modular construction, reducing the completion and delivery time from 2.5-3 years to just 1 year. A public housing project in Shenzhen, Guangdong, utilized 6,028 concrete modules for assembly, resulting in a substantial reduction in construction time compared to traditional methods. In rural Henan, a prefabricated house can be built in as little as 4 hours, demonstrating remarkable efficiency improvements.
Outstanding environmental benefits: Prefabricated houses complete most of the construction processes in factories, reducing on-site construction pollution. Fujian Province has achieved a reduction of over 70% in construction waste by developing prefabricated assembly-type buildings. A public housing project in Shenzhen, Guangdong, significantly reduced noise, dust, construction waste, and traffic congestion through on-site cast-in-place connections, aligning with the trend of green building development.
Strong quality controllability: Prefabricated houses adopt a parallel operation mode in factories, combined with automated three-dimensional warehouses and intelligent production lines, enabling refined and standardized production. With advancements in construction technology, the precision of component production continues to improve, resulting in better quality stability compared to traditional on-site construction and effectively avoiding quality fluctuations caused by human factors.
Long service life: Taking prefabricated houses in rural Henan as an example, their designed service life is up to 70 years, comparable to that of traditional brick-and-mortar houses. Moreover, due to the controllable quality of factory production, the maintenance costs during long-term use are lower, further highlighting their economic utility.
