What is the difference between the first-class and super-first-class qualifications of construction engineering, and what can be upgraded in Hubei?

Super qualification is popular all over the country. Can cross provinces and industries. "What can I apply for for qualification upgrade" is meaningless! Who can find out which ones meet the requirements and can apply for qualification upgrade? All qualified enterprises can apply for qualification upgrade.

The special qualification is approved by the Ministry of Housing and Urban-Rural Development, and the first qualification is approved by the provincial housing and urban-rural development department.
