Luoshan Prefabricated Panel House Evaluation

The evaluation of prefabricated panel houses in Luoshan should be carried out comprehensively from multiple dimensions, dividing safety levels and providing handling suggestions according to the 'Standards for the Appraisal of Dangerous Houses'. Homeowners can inquire about the evaluation reports through multiple channels. Details are as follows:

The evaluation content covers five major aspects:

1. Building foundation stability testing: Focus on observing the foundation settlement situation, checking the weathering degree of foundation materials (such as concrete and masonry), and determining whether there is a risk of uneven settlement.
2. Load-bearing structure condition assessment: Map the crack distribution of load-bearing components such as walls, beams, columns, and floor slabs, record the degree of deformation and cross-sectional damage data, and assess whether their load-bearing capacity meets the standards.
3. Roof system safety inspection: Detect the aging condition of the waterproof layer, measure the deflection value of the purlins, and determine whether there are potential leakage or collapse hazards on the roof.
4. Enclosure structure status survey: Use a hollow drum detector to check the bonding strength between the outer wall rendering layer and the base layer, measure the deformation amount of door and window frames, and assess the air tightness and durability of the enclosure structure.
5. Analysis of influencing factors in the usage environment: Examine the stability of the slopes around the house, evaluate the perfection of the drainage system (such as rainwater pipes and apron slopes), and analyze the potential impact of environmental factors on the safety of the house.

Evaluation levels and handling suggestions:
According to the test results, the safety levels of prefabricated panel houses are divided into four levels:

• Level A: The structure is intact, with no dangerous points in the load-bearing components. The house is generally safe and requires no treatment.
• Level B: Basically intact, with minor defects in individual components (such as small cracks and local weathering), but these do not affect the safety of the main structure. It is recommended to regularly monitor and repair local problems.
• Level C: Some load-bearing structures do not meet the standards, and local areas pose a danger (such as excessive cracks in beams and columns and severe deformation of floor slabs). Reinforcement should be prioritized; if the reinforcement cost exceeds 70% of the reconstruction cost, demolition and reconstruction should be considered.
• Level D: The load-bearing structure has completely failed, and the house constitutes a dangerous building in its entirety. It should be immediately demolished to eliminate safety hazards.

Ways to inquire about the evaluation report:
At the beginning of 2026, the housing and urban-rural development department had completed the investigation and filing of prefabricated panel residential buildings across the country, and the data is publicly available. Homeowners of prefabricated panel houses in Luoshan can inquire about the house safety appraisal reports by carrying their real estate certificates or ID cards through the following methods:

1. Offline channels: Community neighborhood committees, sub-district offices, or local housing and urban-rural development bureau windows.
2. Online channels: The official website of the local housing and urban-rural development bureau.
