Demolition of Prefabricated Panel Houses in Nantong

Prefabricated panel houses in Nantong are not directly demolished but are subject to refined handling based on their actual conditions. The specific handling methods are as follows:

I. Regular Safety Inspections Nantong implements a regular safety inspection system for urban residential buildings constructed more than 25 years ago. For multi-family prefabricated panel houses, the inspection cycle is shortened to once every 5 years, while for other residential buildings, it is once every 10 years. The inspection covers key indicators such as foundation settlement, wall cracks, and pipeline aging, and professional testing is used to assess the structural safety of the buildings. The results of the inspection reports directly determine the subsequent handling methods for the buildings, ensuring that potential risks are identified and intervened in a timely manner.

II. Graded Handling Based on Safety Appraisals According to the building safety appraisal reports, prefabricated panel houses are classified into four levels based on their degree of danger:

• Grade D Dangerous Buildings: If a building is appraised as Grade D (the load-bearing structure's capacity severely fails to meet requirements, and the entire building is in danger), it must be demolished and rebuilt to eliminate major safety hazards.
• Grade A/B Buildings: If a building is rated as Grade A (the structural load-bearing capacity meets normal usage requirements, with no dangerous points) or Grade B (individual components have aging hazards but do not affect the main structure), it can continue to be inhabited normally, and only routine maintenance of locally aging components is required.
• Grade C Buildings: If a building is rated as Grade C (part of the load-bearing structure's capacity fails to meet requirements, and the building is partially in danger), professional reinforcement and repairs (such as adding supports, repairing cracks, and replacing aging pipelines) are needed to enhance structural safety. After passing a re-inspection, the building can continue to be used.

III. Demolition for Urban Major Projects If prefabricated panel houses are included in the land scope of urban major projects (such as subway construction, school building, and hospital expansion), they need to be demolished according to planning requirements. Such demolitions are usually accompanied by compensation and resettlement policies to ensure the legitimate rights and interests of residents.

Nantong adopts a closed-loop management mechanism of 'inspection-appraisal-handling' to balance building safety and resource utilization efficiency, avoiding a one-size-fits-all approach to demolition. Residents can proactively contact the housing and construction department or professional institutions for specific handling plans based on inspection reports or appraisal results to ensure living safety.
