Prefabricated Housing Solution

The prefabricated housing solution covers aspects such as project background, definition and characteristics, and customized construction plans, as detailed below:

Project Background

With the acceleration of urbanization, traditional construction methods have become increasingly problematic in terms of environmental protection, efficiency, and cost. Prefabricated housing, as a new construction approach, has gained widespread application due to its advantages in energy conservation, environmental protection, and rapid construction.

Definition and Characteristics of Prefabricated Housing

• Definition: Parts of the house, such as walls, roofs, and floors, are prefabricated in factories and then transported to the construction site for assembly.
• Characteristics:
  • Environmentally Friendly and Energy-Efficient: Utilizes eco-friendly materials, reduces pollution at the construction site, and lowers energy consumption.
  • Fast Construction Speed: Factory prefabrication and on-site assembly shorten the construction cycle. For example, in rural areas of Henan, the fastest construction time for a prefabricated house is two hours, and for a large villa, it takes about four hours. In the public housing project in Shenzhen, Guangdong, the completion and delivery time was reduced from 2.5 to 3 years to just one year.
  • Stable Quality: Standardized factory production ensures the quality of the house. Each 'building block' has a detailed 'identity card', and steel bar positioning is accurate to the millimeter.
  • Controllable Cost: Reduces construction costs and improves economic efficiency. In rural areas of Henan, the cost per square meter of a prefabricated house is over 300 yuan, and a 200-square-meter house costs only around 70,000 to 80,000 yuan.

Customized Construction Plan for Prefabricated Housing

• Construction Preparation:
  • Site Preparation: Level the site, set up temporary facilities, and ensure good traffic conditions.
  • Personnel Preparation: Organize a construction team, including project managers and construction workers, and provide technical training.
  • Material Preparation: Purchase prefabricated components and auxiliary materials that meet standards.
• Construction Process:
  • Foundation Construction: Level and compact the foundation, make foundation formwork, and pour concrete.
  • Component Transportation and Storage: Use appropriate tools for transportation and stack components in order.
  • Component Assembly: Assemble components according to design requirements and connect them firmly using bolts, welding, etc.
  • Indoor and Outdoor Decoration: Carry out indoor decoration such as walls and floors, and outdoor decoration such as doors and windows.
• Construction Quality Control: Ensure that raw materials meet standards, strictly follow construction processes and quality standards, and inspect concealed works.
• Construction Schedule: Foundation construction takes 15 days, component transportation and storage take 5 days, component assembly takes 20 days, indoor and outdoor decoration takes 30 days, and final inspection and acceptance take 5 days, totaling 85 days.
• Cost Control: Purchase materials according to design requirements to avoid waste, and合理安排 (reasonably arrange) construction personnel to improve efficiency.
