Prefabricated Panel Houses in Suzhou

Prefabricated panel houses in Suzhou mainly include wall-panel houses, and the relevant information and management requirements for prefabricated concrete components are as follows:

Basic Information on Wall-Panel Houses

Wall-panel houses are a type of building that uses prefabricated concrete panels as walls. Research on prefabricated large-panel housing in China began in 1958, and it emerged in Suzhou in the 1970s and 1980s. These houses, with factory-prefabricated components, can significantly save time and labor costs, but they have numerous defects, such as leakage, poor earthquake resistance, and inadequate sound and heat insulation. Since 1985, this type of housing has gradually faded from the scene. For the existing old wall-panel houses, measures such as exterior facade renovation, reinforcement, or inclusion in demolition and reconstruction plans are usually taken.

Information Collection for Prefabricated Concrete Components

• Scope and Timing Requirements for Collection: Starting from January 1, 2025, basic information and product quality information of prefabricated concrete component manufacturers for newly commenced housing construction projects in Suzhou must be collected. By April 1, 2025, all regions should urge and guide relevant enterprises in ongoing projects across the city to complete information collection. The collection scope covers housing construction projects using prefabricated concrete components within the administrative region of Suzhou, involving components such as prefabricated composite floor slabs, prefabricated stair slabs, prefabricated wall panels, prefabricated beams, and prefabricated columns.
• Collection Requirements:
  • Manufacturer Information: Manufacturers should register on the Suzhou Prefabricated Building Management Information Platform, enter basic enterprise information, personnel information, production equipment information, the main types of prefabricated concrete components produced, type test reports, and other materials, and upload a self-discipline commitment letter. The platform will generate a registration form for prefabricated concrete component manufacturers in Suzhou and a corresponding QR code, which construction, construction, and supervision units can scan to view basic manufacturer information.
  • Component Information: Manufacturers need to collect information on the supply of prefabricated concrete components in housing construction projects in Suzhou through the platform. The supplying enterprise generates a project material QR code and provides it to the project along with the product certificate, allowing relevant units to scan and verify the collected information.
  • On-Site Inspection Information: For prefabricated concrete components requiring inspection, the supervision (construction) unit scans the project material QR code, uses the "Add Witness Sampling" function to obtain the "Witness Sampling Record Form," and the engineering quality inspection agency scans the "Project Material Sampling Information Code" to verify the information and inspect the samples upon receipt.
