The contracting method can be general contracting or subcontracting.

Scope of subcontracting: The subcontracting unit must complete the subcontracted project by itself and is not allowed to subcontract again. However, special professional technical operations such as air tightness testing, pressure testing of metal containers, debugging of process equipment installation, weld damage control inspection of hoisting projects, piling and advanced decoration are excluded.

Features

The engineering project model represents the mainstream of modern Western engineering project management. It is the perfect combination of construction management model (CM) and design. It is also the successful use of this model to shorten the construction process. An example of the purpose of shortening the construction period and reducing investment. It was once famous for its construction engineering contracting industry that built high-rise buildings and large-scale industrial projects at high speed and low cost. The key to EPC is reliance on competent professional subcontractors and standardized process controls and procedures, so it is widely used in Western developed countries. This is the basis for its simple and efficient design, manufacturing and construction.
