Self-Built House Addition Renovation Safety Inspection and Appraisal Process

As living standards rise, so does the demand for housing. Consequently, to ensure the safety of housing, house safety inspection and certification has become an indispensable task. House safety inspection and certification refers to the scientific detection and analysis of the structure and building materials of the house to assess its safety performance, providing a basis for the scientific management and repair of the house.

House safety assessment generally involves investigations, on-site inspections, structural analysis, and calculations to evaluate the safety of a building. Below, the editor shares a case about "Office Building Structural Safety Assessment."
