Many friends who hear about house testing and appraisal always feel that there are problems with conducting a house appraisal, and often associate it with some very serious words, such as dangerous houses, collapses, tilts, etc.

Of course, ordinary people do not understand this industry, have not been exposed to it, and there is no problem with such associations. Testing and appraisal tell many friends that it is not because of safety hazards that one goes to do a house testing and appraisal. Nine common situations of building structural safety

one

The building structure intends to change its purpose, usage conditions, and usage requirements. The structure has changed the original state of the design. When a new application adds a load to the structure, changes the original layout structure, such as demolishing or weakening bearing components or partially changing the use status of bearing components, frequent situations such as reconstruction and expansion must be tested and evaluated to ensure the safety and normal use of the building structure.

two

When the building structure needs to be renovated by adding layers, mezzanine layers, or other structural forms. This situation will directly affect the safety and use of building structures and must be evaluated. Based on the conclusion of the housing evaluation report, proceed to the next step.

three

The entire building will be moved. A comprehensive migration requires a very professional team operation and is rare. Undoubtedly, it is necessary to conduct a detailed evaluation of the situation, propose potential issues, and make recommendations for comprehensive displacement.

four

When the building structure exceeds its designed service life. At present, the standard stipulates that the general service life for building structure design is 50 years. When the building structure reaches the design service life, necessary testing and identification are required to continue safe use.

five

If a dispute arises due to reasons such as the design, construction, or use of a building, and the parties have reason to suspect it. This situation is also quite common, with water leakage disputes caused by upstairs construction. Seriously, even if a direct result of the judiciary is obtained, the judicial appraisal of housing security is usually suspected by the owner to exist during the construction process. Rough quality, shoddy workmanship, or construction quality and quality issues may lead to quality disputes and contradictions in the building structure. Now, it is necessary to provide an objective and fair evaluation by a third party.

six

From the perspective of maintaining the building structure, understand the current state of the building structure and its reliability within its target service life. Historical buildings, memorial buildings, large public buildings, etc. The so-called target life refers to the number of years that the owner expects to continue using through necessary repairs and maintenance.

seven

The building structure was damaged in disasters and requires reinforcement in order to continue its use. Generally, it refers to the vast majority of force majeure disasters, including fires, earthquakes, floods, etc., which require a high level of technical proficiency from the detection and identification team.

eight

Load changes or structural changes caused by the renovation or decoration of the building's exterior.

nine

When the building structure itself exhibits significant functional degradation or inclination. Building functional degradation refers to the corrosion resistance of building structures. Resistance is a professional term commonly used to refer to the ability to resist external loads or the effects of building structures, i.e. "resistance". When structural cracks or deformed beams and columns appear, reinforced floors that leak water, and building structural vibrations, such as building structures, can be considered an important degradation of building functions.
