In the following situations, a pre-renovation structural safety assessment should be conducted for the Hubei Province Swimming Stadium:
1) Pre-renovation inspection of buildings
2) Regular inspections of key buildings
3) Determination of changes in the use or usage conditions of buildings
4) Continued Use Evaluation of Building Design Criteria
5) Survey conducted for the development of a maintenance and renovation plan for the building complex.

In the following situations, a pre-renovation safety assessment of the building is only required before the sand area swimming facility is remodeled:
1) Building safety assessment and various emergency assessments;
2) Pre-renovation Safety Inspection for Houses
3) Inspection required for extending the usage period of temporary housing.
4) Safety issues identified during usability assessment.
3. Normal usability assessment may be conducted under the following circumstances:
1) Inspection for daily maintenance of buildings;
2) Assessment of Building Functional Use

3) Special assessment for buildings with specific usage requirements.

When a house exhibits any of the following conditions, the house safety appraiser shall promptly entrust a house safety appraisal unit to conduct a house safety appraisal:
1. Foundation or main structure of the house showing significant sinking, cracks, deformation, or corrosion.
2. Houses requiring continued use beyond their designed service life.
3. Damage to the main structure of the building caused by natural disasters, as well as accidents such as explosions and fires.

Houses within twice the excavation depth range.
2. Buildings within the seismic safety distance required by the "Safety Regulations for Blasting Operations" during blasting construction.
3. Structures within a 2x the excavation depth range from the edge of underground construction such as subway and civil defense projects.
4. Structures that may be endangered by excavation and foundation work, blasting operations, or underground construction.
