The second-level constructor is one of the qualification categories of the constructor qualification system, and the constructor is divided into the first-level constructor and the second-level constructor. English translation: builder and assistant builder respectively.
The first-class constructor has high standards, high quality and high management level, which is conducive to international mutual recognition. At the same time, taking into account the large number of construction projects in China, the disparity in the scale of construction projects, the great differences in the level of economic, cultural and social development in different places, and the different requirements for managers in different projects, a second-class constructor was set up to meet the actual needs of construction management.
