General Contracting Model of Construction Projects (1) Characteristics of the general contracting mode of projects The so-called project general contracting mode refers to the owner's contract to a contracting company for all the engineering design, construction, material and equipment procurement, which will carry out substantive design, construction and procurement work, and finally hand over to the owner a project that has reached the utilization conditions.The project contracted according to this mode is also called "turnkey project". (2) Advantages and disadvantages of project general contracting model 1. advantages (1) The contract relationship is simple and the workload of organization and coordination is small.The contractual relationship is greatly simplified, and the supervisory engineer mainly coordinates with the general contractor of the project.Many coordination workloads are transferred to the general contractor and its subcontractors, which greatly reduces the coordination workload of construction supervision units. (2) To shorten the construction period.Because the design and construction are arranged by a unit as a whole, so that the two stages can be organically integrated, generally the design stage and the construction stage can overlap each other, so it is advantageous to the progress target control. (3) Favorable for investment control.The overall consideration of design and construction can improve the economy of the project. From the point of view of value engineering or life-cycle cost, obvious economic results can be achieved, but it does not mean that the price of the general contract of the project is low.
