Guiyang Prefabricated Assembly House

The prefabricated assembly house in Guiyang is a building model where building components are prefabricated in factories and then assembled on-site. It features high efficiency, environmental protection, shortened construction periods, good quality, strong adaptability, and excellent performance. It is widely applied, and related enterprises are developing well.

Advantages and Characteristics

• High Efficiency and Environmental Protection: Water consumption per square meter of building area can be reduced by over 60%, and energy consumption by over 30%, effectively minimizing resource waste.
• Labor and Time Savings: By transferring a large amount of 'on-site work' to 'factory work', labor costs are reduced by about 70%, and construction periods by about 30%, enhancing construction efficiency.
• High Construction Quality: Building components produced in factories are marked with QR codes. Scanning these codes provides information on manufacturing and installation, such as production dates, workers involved, raw materials, and inspection quality, ensuring precise and efficient on-site assembly.
• Strong Adaptability: Given Guiyang's mountainous terrain and humid climate, the modular design and dry construction methods of prefabricated assembly houses reduce on-site wet work, minimize disturbances to the mountainous environment, and improve construction efficiency and quality control.
• Excellent Performance: Light steel structures and composite insulation wall systems are commonly used, offering excellent thermal insulation and moisture resistance, suitable for the local climate. The structural system undergoes 3D modeling and node optimization using BIM technology to ensure assembly accuracy and seismic performance. High integration allows for pre-installation of water and electricity pipelines in factories, reducing on-site cross-operations. Some projects also incorporate green building materials and energy-saving technologies to enhance overall building energy efficiency.

Application Status

It is expected that by the end of 2025, the newly started prefabricated building area in Guiyang will account for more than 60% of the newly built building area. From 2021 to 2023, the newly started prefabricated building area has increased year by year, and the proportion has also continuously increased. Currently, there are more than 20 cooperative projects among enterprises, covering ordinary housing construction, schools, factories, etc. Several affordable housing and rural revitalization projects in the area have adopted this building model, demonstrating good adaptability.
