根据《建设工程质量管理办法》，建设工程必须达到合格标准，不合格的工程不准交付使用。但在我国，建设工程还没有完全成为“商品”，基本上还是预约加工形式，造起来的房子很难推倒。这样一些工程被质量部门定为不合格后，施工企业便无限期返修下去，一些建设单位拖延不起，? According to the “Quality Management Measures for Construction Projects”, the construction project must meet the eligibility criteria and unqualified projects must not be delivered for use. However, in our country, the construction project has not completely become a “commodity”. Basically, it is still an appointment form for processing, and it is very difficult for the built-up house to be toppled. After these projects were deemed as unqualified by the quality department, the construction companies would go back indefinitely. Some construction units could not afford to delay.
