Lighting projects require road and urban lighting engineering construction qualifications, which are divided into first, second and third levels. However, it is currently being reformed. There was a legend that the classification was cancelled, but now it is said that there are only one and two classes. The official document has not yet come down, and the official national document shall prevail.
There is also a qualification for lighting engineering, namely design qualification, which is generally divided into Grade A and Grade B. The specific requirements can be checked on the Internet. There are requirements for the number and category of technical personnel, so I will not repeat them here. The above two qualifications are sometimes used in combination, especially for major projects. Bidding generally requires double A qualifications, that is, both design and construction are required to be Class A qualifications. So far in the country, there are 168, among which Guangdong is the most. Followed by East China, namely Jiangsu, Zhejiang, and Shanghai. Beijing is less because of the higher requirements of Beijing. It is impossible for lighting manufacturers in Beijing to obtain construction qualifications, nor is it possible to obtain design qualifications. In Guangdong and Jiangsu, especially Yangzhou, many factories have construction qualifications and design. Qualifications, and even many Double A qualifications, have a lot to do with local policies. This is impossible in Beijing! However, due to the large number of Beijing Ministry of Construction and its affiliated architectural design institutes, the level of which is also among the best in the country, the design level of Beijing Lianghua Engineering Company is also leading in the country.
Now the qualifications have changed a lot. Many qualifications are now being merged. In addition to the aforementioned changes in lighting engineering qualification levels, lighting engineering qualifications may also be merged with mechanical and electrical installation, electronics and intelligent construction, and lighting design qualifications may also be merged into decoration engineering design qualifications. The country hopes to lower the threshold through this kind of merger. In addition to qualifications, the most important thing for a company is to increase the level and ability of its business. This is the fundamental.
