Main Load Testing Content
Gather construction documents and design plans, as well as geological survey reports related to the property.
2. Conduct random inspections of concrete strength for columns, beams, and slabs according to national standards.
3. Conduct sampling inspections in accordance with the national testing specifications to check the steel reinforcement configuration of the columns and the thickness of the protective layer for the steel bars.
4. Inspect the cross-sectional dimensions of the column beams and the thickness of the floor slabs.
5. Inspect the quantity, current condition, and distribution of structural cracks in the house.
6. Conduct inspections to determine the quantity, current status, and distribution of cracks in the building's walls.
7. Conduct timely detection and analysis of potential uneven settlement of the building.
8. Inspect the entire house for any tilting and the extent of the tilt.
9. Based on the test results, national standards, and the actual usage conditions of the factory, conduct relevant calculations and analyses to determine the building's load-bearing capacity and structural safety, and provide recommendations for safe building usage.
Load-bearing testing, refer to relevant specifications.
