Shenzhen Building Safety Inspection and Appraisal
I. Hazardous Building Inspections - A hazardous building refers to a structure where the load-bearing components have become dangerous, losing stability and load-bearing capacity, posing a potential collapse risk at any time, and cannot ensure the safety of use. II. Calculation of Building Integrity and Hazard Rates - The integrity and damage levels of buildings are measured by floor area, with the building itself serving as the unit of assessment. The integrity rate of buildings is an important technical and economic indicator for property management and operation units (including property management enterprises), representing the sum of the floor area of sound buildings and the floor area of buildings in basic good condition. III. Technical Requirements for Dismantling Hazardous Buildings - (1) A reinforcement design plan must be issued by the original design unit or a unit with corresponding design qualifications. (2) Construction must be carried out by a construction enterprise with the appropriate qualifications. (3) Construction quality supervision must be conducted by a supervision company with the appropriate qualifications.
1. Residential Inspection Content 1: Residential Safety Inspection - Technical Project: Assessing the damage status of building structures, analyzing the process to determine the safety of the house. Applicable Scope: Signs of dangerous buildings already identified. 2. Residential Condition Assessment - Inspection Items: Checking the damage status of building structures, renovations, and equipment, determining the damage level. Applicable Scope: Houses and property management requiring the determination of damage levels. 3. Residential Damage Trend Inspection - Technical Project: Monitoring process to detect or potentially cause damage such as deformation, displacement, and cracks due to the impact of external environmental factors (e.g., adjacent construction projects) and internal factors like design, construction, and usage. Scope: Various factors that may cause or have caused damage or require monitoring of houses. 4. Residential Modification Inspection - Technical Project: When modifying the architectural structure and management functions of a house, analyzing and inspecting the original structure to determine structural safety, and evaluating the possibility of changing the structural and usage system functions. Applicable Scope: Houses requiring increased loads or structural changes. 5. Building Seismic Performance Testing - Test Items: Current status of building quality inspections, in accordance with seismic fortification requirements, under specified seismic intensity and safety standards for construction processes. Applicable Research Scope: Buildings without seismic fortification or with fortification levels lower than the current legal requirements in our country, particularly environmentalist architecture.
