Common types of safety appraisal for existing buildings
Author:
Most people do not have much understanding of housing safety appraisal, but in reality, housing appraisal reports are effective preventive measures for resolving housing transaction disputes. Therefore, while strengthening the management of building safety, it is also necessary to develop sound standards for building safety appraisal and testing to ensure the safety of residents' lives and property.
In actual housing appraisal work, the existing civil building inspection and appraisal work mainly includes several types of engineering problems such as accidental effects, construction quality, and contract disputes.
1. Construction quality
Due to the current low quality of construction personnel and lack of effective management in China's construction market, there are some engineering quality problems such as substandard construction quality, cutting corners on materials, and early damage during construction. Generally, for these newly built commercial or office buildings, in addition to quality inspection, the structure of the building also needs to be evaluated. This is an internal inspection of the building structure to determine whether it meets the requirements.
2. Contract disputes
Nowadays, civil disputes arising from the renovation, construction, decoration and other construction projects of houses are constantly occurring. Building safety appraisal can make judgments on the extent and causes of damage to houses, providing factual basis for judicial judgments and maintaining judicial fairness
3. Accidental action class
Existing buildings are subject to external factors such as fires, earthquakes, typhoons, etc. during use, resulting in varying degrees of structural damage. For these civil buildings that have undergone accidents, safety appraisal work will be carried out to assess the level of damage to the buildings. After professional technical appraisal and analysis, it is better to know whether the current building can continue to be used, or whether it can be reinforced before use.
1) Civil building inspection and appraisal after fire
For buildings that experience fires or explosions, most structures are severely damaged. Material strength testing, on-site testing, component load testing, and verticality testing of components such as walls are required for these damaged structures.
2) Civil building inspection and appraisal after natural disasters such as earthquakes and floods
In the event of a high magnitude earthquake or a building that has been soaked in water for a long time, safety assessment work needs to be carried out to determine whether it can continue to be used or reinforced before it can continue to be used.

How is witness sampling conducted?
Witness sampling is one of the supervisory management methods. Witness refers to the activity of on-site supervision by the supervising engineer on the completion of a certain process by the contracting unit. Witness sampling refers to the supervision activity of on-site sampling of materials, semi-finished products, and components related to structural safety used in engineering projects, as well as the inspection of the effectiveness of process activities.

What are the main testing items for building environment testing
Environmental testing mainly detects factors such as chemical pollutants and physical and biological pollution. Environmental detection and governance is a highly technical emerging industry that utilizes GIS technology to design environmental detection networks. The information collected from environmental detection can be stored and displayed in a timely manner through GIS, and detailed site monitoring and analysis can be conducted on the selected evaluation area.

How to detect the quality of construction projects?
Construction project quality inspection refers to the inspection of construction materials, building components, equipment, and physical quality of the construction site, as well as the testing of structural safety and main usage functions of the construction project design, in accordance with relevant national laws, regulations, and standards, commissioned by the inspection agency in the activities of building construction, expansion, renovation, and municipal infrastructure engineering.

What testing is required for building curtain walls?
Building curtain walls require physical performance testing (wind pressure resistance, air permeability, rainwater leakage, and plane deformation performance testing reports), which is generally referred to as the four properties testing of curtain walls, compatibility and adhesion testing reports of silicone structural adhesives and weather resistant sealants, and on-site tensile force testing reports of embedded parts.
