Due to natural disasters such as earthquakes and typhoons, as well as human factors like fires and explosions, the existing buildings have sustained varying degrees of damage or even destruction. Additionally, the current structure of the buildings is trending towards higher levels and greater flexibility, which may lead to hazardous vibrations under wind loads, seismic loads, and the influence of surrounding environments.

During construction, the house failed to meet design requirements due to reasons like using substandard materials. Additionally, unauthorized alterations during use further complicate the issue, making it difficult to ensure the safety of the house.

House quality inspection involves using certain technical means and methods to check and measure the quality of existing buildings (not under construction), particularly their structural quality, through dynamic monitoring. This process ensures the safety of the nation's people and property, promotes the full and rational utilization of existing housing resources, and guarantees social stability, thus yielding significant social and economic benefits. House inspection, also known as house quality inspection and evaluation, refers to the process by which qualified inspection units test, evaluate, and issue reports on the quality of houses.
