It takes time and energy for construction enterprises to obtain the construction qualification certificate, so they should pay more attention to the maintenance of construction qualification. However, some construction enterprises do not pay much attention to this aspect, which will lead to the downgrade of the construction qualification certificate. So what will lead to demotion? Let's take a look with Xiaobian.

一、有违规现象

1、 There are violations

资质降级的重要原因就是公司有违规情况。建筑公司的工程项目超出了自身资质等级，会责令停止施工，降低资质等级。如果情况比较严重，可能会被吊销资质证书，如果情节严重，构成犯罪的，会依法追究刑事责任。

The important reason for qualification degradation is that the company has violations. If the engineering project of the construction company exceeds its own qualification level, it will be ordered to stop construction and reduce the qualification level. If the situation is serious, the qualification certificate may be revoked. If the circumstances are serious and constitute a crime, criminal responsibility will be investigated according to law.

二、出现事故

2、 Accident

在施工的现场出现了重大伤亡。通常3人以上就是属于重大建筑事故的伤亡人数。这需要判断事故的严重性，这没有具体的衡量标准。因此，企业应当尽量避免事故，如果发生了要及时救援，并且上报到相关部门。

Heavy casualties occurred at the construction site. Usually, more than 3 people are the casualties of major construction accidents. This requires judging the severity of the accident, which has no specific measurement standard. Therefore, enterprises should try to avoid accidents. If they happen, they should rescue them in time and report to relevant departments.

三、生产许可证有问题

3、 There is a problem with the production license

1.企业没有生产许可证，就不能进行施工。当然，企业在进行建筑资质升级的时候，生产许可证也要重新审核，有的企业就忽略了这一规定。

1. The enterprise cannot carry out construction without production license. Of course, when enterprises upgrade their construction qualification, the production license should also be reviewed again, and some enterprises ignore this provision.

2.通常企业在升级一段时间以后，就需要重新审批资质。如果建筑资质超出了审批的期限，这也会面临降级的风险。

2. Generally, after upgrading for a period of time, the enterprise needs to re approve the qualification. If the construction qualification exceeds the approval period, it will also face the risk of degradation.
