Renovation Plan for Houses with Prefabricated Floor Slabs

The renovation of houses with prefabricated floor slabs should be carried out in a scientific manner, combining professional assessments, functional upgrades, policy guidance, and priority planning, and implemented step by step.

1. Thorough Inspection and Professional Assessment
Before renovation, it is necessary to commission a qualified inspection agency to conduct a comprehensive inspection of the house, focusing on identifying issues such as wall cracks, steel bar corrosion, and foundation settlement, and issue a "House Safety Appraisal Report." Based on the report results, the danger level is classified (Grades A-D): If the main structure is undamaged (such as Grades A and B), reinforcement measures should be prioritized; if there are serious safety hazards (such as Grade D, indicating overall danger), demolition and reconstruction are required; Grade C partially dilapidated houses can enhance safety through repair and reinforcement or reconstruction.

2. Functional Upgrades and Renovation

• Sound Insulation Treatment: Install sound insulation boards on walls and replace windows with double-glazed units to improve sound insulation by approximately 70%, enhancing living comfort.
• Waterproofing and Structural Reinforcement: For roof leakage issues, remove the original waterproof layer and relay polymer waterproof membranes; wall cracks can be repaired by grouting or reinforced with steel plates; when the foundation is unstable, enhance load-bearing capacity through piling or grouting techniques.
• Space Optimization: Adjust the layout of the house according to modern living needs, such as adding an independent entrance hall, optimizing the kitchen ventilation system to solve the problem of oil fume backflow, or improving living room lighting by removing non-load-bearing walls and adding skylights.

3. Adherence to Policy Guidance
According to the "15th Five-Year Plan for Urban Renewal," renovation should focus on C and D-grade dilapidated houses, with priority given to demolishing D-grade houses and repairing, reinforcing, or rebuilding C-grade houses. At the same time, strict restrictions should be imposed on large-scale demolition and construction: the demolished area within the renewal unit should not exceed 20%, the demolition-to-construction ratio should not exceed 2, and renovation should be encouraged as the mainstream approach.

4. Clarification of Renovation Priorities

• Must Be Demolished: Houses with severely damaged main structures that cannot be repaired, unable to withstand natural disasters (such as earthquakes and floods), or located on municipal planning land.
• Priority for Renovation: Partially dilapidated houses identified as Grade C can significantly enhance safety and extend service life through reinforcement and reconstruction.

5. Compensation and Resettlement (if demolition is involved)

• Monetary Compensation: Calculated comprehensively based on the prices of surrounding second-hand houses, decoration compensation, moving expenses, etc., taking into account the depreciation factor of the house, and signing a written contract to clarify the terms.
• Property Rights Exchange: Provide original site relocation or off-site resettlement in new houses, suitable for groups seeking stable residence, with clear exchange ratios and delivery times.
• Housing Voucher Policy: Some regions allow compensation in the form of housing vouchers, enabling holders to purchase commercial housing in designated areas, with specifics referring to local policy details.

Key Basis: All renovation measures must be based on the "House Safety Appraisal Report" issued by a professional institution to ensure the scientific and compliant nature of the plan.
