What Are the Prefabricated Housing Solutions

Prefabricated housing solutions mainly include modular construction solutions, box component assembly solutions, and customized prefabricated housing construction solutions. Details are as follows:

Modular Construction Solution: This solution breaks down the entire building into multiple independent modules. These modules are manufactured in a factory, covering building elements such as ceilings, floors, and water and electricity pipelines. After manufacturing, the modules are transported to the construction site for assembly. Taking the affordable housing project in Shenzhen, Guangdong as an example, five residential buildings nearly 100 meters high were assembled from 6,028 concrete modules. Compared with traditional construction methods, this solution significantly shortens the completion and delivery time, reducing it from the original 2.5 to 3 years to 1 year, while also reducing on-site labor by about 50%.

Box Component Assembly Solution:

• Overlapping Assembly of Upper and Lower Boxes: Suitable for constructing buildings up to 12 stories high. In non-seismic areas, boxes below 5 stories may not need to be connected, relying on their own weight and friction for stability; in seismic areas or for taller buildings, connections are made through methods such as post-tensioning, casting full-length balconies or corridors, bolt connections, and pouring concrete structural columns in reserved chain slots.
• Interlaced and Stacked Assembly of Box Components: This assembly method avoids repetition of adjacent sides of the boxes, achieving a more economical building effect.
• Assembly of Box Components with Prefabricated Panels: This method saves materials and offers flexible layout design. For rooms with many equipment pipelines and heavy decoration workloads, using box components can reduce on-site workload.

Customized Prefabricated Housing Construction Solution:

• Construction Preparation: Includes site preparation (such as site leveling, setting up temporary facilities, ensuring good construction roads), personnel preparation (organizing construction teams and providing technical training), and material preparation (purchasing prefabricated components and auxiliary materials).
• Construction Process: Covers foundation construction (foundation treatment, making foundation formwork, concrete pouring), transportation and storage of prefabricated components (using appropriate transportation tools to ensure safe transportation, stacking in designated areas in order), assembly of prefabricated components (assembling wall, roof, floor, and other components in sequence according to design requirements, using bolt and welding connections), and indoor and outdoor decoration (indoor decoration of walls, floors, and ceilings, outdoor decoration of doors, windows, stairs, balconies, and other facilities).
• Construction Quality Control: Quality control and acceptance of raw materials, construction processes, and concealed works.
• Construction Schedule Arrangement: The total construction period is 85 days, including an estimated 15 days for foundation construction, 5 days for transportation and storage of prefabricated components, 20 days for assembly of prefabricated components, 30 days for indoor and outdoor decoration, and 5 days for completion acceptance.
• Cost Control: Strictly control material and labor costs, avoid waste, and improve construction efficiency.
