Differences between mechanical and electrical installation qualification and mechanical and electrical equipment installation qualification:

The general contracting qualification of mechanical and electrical engineering construction and the professional contracting qualification of building mechanical and electrical installation engineering are divided into three levels: Level 1, level 2 and level 3. However, they are different in terms of handling conditions and undertaking business scope, which is an inclusive relationship (the total package includes more than the special package).

Taking the same level (Level 3) qualification as an example, the net assets of general contracting qualification enterprises are required to be more than 8 million, while the net assets of special contracting qualification enterprises only need to reach 4 million. All kinds of registered personnel and technical personnel required for the general contracting qualification of mechanical and electrical engineering construction are almost twice as much as the special contracting qualification of mechanical and electrical installation engineering.

From the perspective of business scope, the third level of the general contractor can undertake the construction of all kinds of mechanical and electrical projects with a single contract value of less than 15 million yuan, while the third level of the special contractor can only undertake the installation of equipment, lines and pipelines, and the production and installation of non-standard steel structure components for all kinds of construction projects with a single contract value of less than 10 million yuan.
