While promoting the progress of the industry, it also further expands the competition among industries. Moreover, in this competition, the success or failure of the building does not depend on how high the technical content of the building is and how expensive the materials are, but on the overall quality and safety of the building. Good building quality safety is the most direct manifestation of the extension of building use value. So now the major construction industries have also shifted their focus to how to improve the quality and safety of buildings, and also strengthened the supervision and management of their quality and safety. However, according to the current development situation, the scope of supervision is still not comprehensive.展开更多
