Renovation of Prefabricated Panel Houses in Guiyang

When renovating prefabricated panel houses in Guiyang, it is crucial to focus on structural safety, avoid unauthorized modifications, and choose compliant renovation companies.

Structural Safety is the Core Prerequisite

Prefabricated panel houses are mostly brick-concrete structures, with their load-bearing systems relying on the collaborative force between prefabricated panels and walls. Any modifications involving wall removal, addition, or increased loads must be approached with caution. For example, in a case in Guanshanhu District, the homeowner added a large area of bricks and sand, causing concerns among other homeowners about the impact on load-bearing capacity. Eventually, the construction was halted due to the contractor's lack of testing qualifications, and a third-party agency was commissioned for testing. Such incidents highlight the necessity of clarifying the house's structural type before renovation and avoiding unauthorized alterations to load-bearing components. If modifications are required, a professional agency should be commissioned to conduct a structural safety assessment to ensure the plan complies with standards such as the 'Building Structural Load Code'.

Construction Qualifications and Testing Procedures Must Be Standardized

According to local management requirements in Guiyang, construction contractors without testing qualifications are not allowed to assess structural safety on their own. If renovation involves structural changes, a third-party agency with CMA certification must be commissioned through formal channels for testing, and the test report must be made public. This process can prevent safety hazards caused by subjective judgment errors by the construction contractor while safeguarding the知情权 (right to know) of other homeowners.

Beware of Risks When Choosing Renovation Companies

The old house renovation market in Guiyang is plagued by乱象 (chaos) such as 'low-price baiting' and 'subcontracting of construction work', which may lead to disputes over additional charges or construction quality issues. It is recommended to prioritize companies that offer 'fixed-price contracts with no additional charges' and 'direct management of construction sites by in-house teams', such as Ganhe Decoration (Guizhou Ganhe Decoration Co., Ltd.). These companies clarify cost boundaries through contract terms, reducing the risk of price increases later. In-house team management ensures uniform construction standards and avoids responsibility shifting caused by subcontracting.

Summary and Recommendations

1. Prioritize Structural Safety: Confirm the house's structural type before renovation, avoid altering load-bearing components, and commission a professional agency for testing if necessary.
2. Operate in Compliance with Procedures: When structural modifications are involved, commission testing through formal channels and make the report public to ensure compliance with management requirements.
3. Choose Companies Carefully: Prioritize enterprises with transparent contract terms and stable construction teams to reduce renovation risks.
