What are the main contracting modes of engineering projects

There are five main contracting modes for engineering projects: pmc, cmc, epc, ep+c, cgc.

Specifically analyzed as follows:

1, PMC engineering construction project management contracting owner will be entrusted with the task of project management of the construction project to a consulting firm for engineering project management, CMC construction project management contracting owner entrusted to a contractor responsible for the coordination of design and management of construction, EPC engineering general contracting owner will be contracted to a contractor for a series of work such as design, procurement, construction and so on. Coordinate with the design and manage the construction, EPC project general contracting owner will design, procurement, construction and a series of work contracted to a contractor.

2, the difference between engineering projects and construction projects. Construction project is the abbreviation of the capital construction project is also known as infrastructure projects. In one or several construction sites, in accordance with an independent overall design for the construction of the construction of the overall of each individual project, the construction of engineering projects to expand the various types of works carried out.

3, construction project contracting mode, also known as engineering contracting mode, refers to the form of economic relations between the two sides of the construction project contracting. According to the scope and content of the contracting can be divided into the whole process of contracting, phase contracting and special contracting, according to the contracting in the relationship between each other, can be divided into general contracting, sub-contracting, exclusive contracting, joint contracting and so on. General contracting.

Advocating the implementation of general contracting of construction works, prohibit the dismemberment of construction works contracting. The contracting unit of the construction project may contract the survey, design, construction and equipment procurement of the construction project together to a general contractor, or may contract one or more of the survey, design, construction and equipment procurement of the construction project to a general contractor; however, it is not allowed to dismember the construction project which should be accomplished by a contracting unit into several parts to be contracted to several contracting units.

Construction works shall promote general contracting and prohibit dismemberment contracting. The contractor of a construction project may contract the survey, design, construction and equipment procurement of the construction project to a general contractor; one or more of the survey, design, construction and equipment procurement of the construction project may also be contracted to a general contractor; however, the construction project which should be accomplished by a single contractor shall not be dismembered into several parts and contracted to several contractors.

In summary, the contractor of the engineering contract can not be issued separately. Regardless of the manner in which the contractor contracted with the contractor, the contractor shall not contract the construction works in pieces, that is, the construction works which should be completed by one contractor are dismembered into several parts and contracted to several contractors.
