2. Scope of projects that can be contracted by different qualifications
1Grade A qualification: can undertake the construction of all kinds of foundation projects.
2Grade 2 qualification
Can undertake the construction of the following projects:
①highly100Industrial and civil construction works below meters and their height120Foundation foundation works for structures under meters;
②Not exceeding depth24M rigid pile composite foundation treatment and depth does not exceed10Other ground treatment works;
③A single pile bears the design load5000Pile foundation works below thousand cattle;
④The excavation depth shall not exceed15Meters of foundation pit enclosure project.
3Level 3 qualification
Can undertake the construction of the following projects:
①highly50Industrial and civil construction works below meters and their height70Foundation foundation works for structures under meters;
②Not exceeding depth18M rigid pile composite foundation treatment or depth does not exceed8Other ground treatment works;
③A single pile bears the design load3000Pile foundation works below thousand cattle;
④The excavation depth shall not exceed12Meters of foundation pit enclosure project.
Foundation pit engineering requires the construction of foundation pit supporting units with corresponding qualifications, especially the deep foundation pit supporting units. Once the construction accident of deep foundation pit occurs, it is easy to cause group death and group injury, and the consequences are quite serious. In the construction of deep foundation pit engineering, supervision rules must be formulated to clarify the technical requirements of deep foundation pit engineering and the key points of inspection on the construction site.
