The EPC project has the characteristics of wide coverage, long construction period and many uncontrollable factors. Compared with the traditional general construction contract, the EPC project has higher requirements for the whole process cost control of the contractor. Municipal general contracting enterprises need to take corresponding cost control measures in bidding, design, procurement, construction, completion settlement and other stages, so as to minimize uncontrollable risks and strive for the maximum economic benefits of enterprises.展开更多

With the change of China's economic system, the contract mode of the project has also changed. In order to guarantee the process of development of nuclear power project goes well, the country's nuclear power project in the new EPC contract mode, the following based on the brief analysis of EPC contract mode, to explore how nuclear power project in EPC mode to ensure the progress control, thereby reducing the problem in the process of nuclear power project, and promote the development of the process of nuclear power project in China, perfecting the deficiencies in the progress control of nuclear power project under EPC mode.展开更多

A new method which vibrates the system in a two-dimensional circular mode has been appliedto the EPC process. The molding properties of unbonded sand obtained by this new vibration mode are investigated andcompared with those in the one-dimensional vertical mode. For adequate compaction of sand. the circular vibration mode ismore effective than the vertical mode. Sand became more fluidized by the circular vibration and the particle pressure coefficientwas close to unity The particle pressure coefficient, which is defined as the ratio of horizontal to vertical sand pressure, isresponsible for the effectiveness of sand filling.展开更多

The risk factors in the construction stage involve the design, procurement, construction organization and other processes of the project. Therefore, the effect of risk management in the construction stage will directly affect the quality, cost and construction progress of the project. In actual project management, managers need to identify key risk factors in the construction stage, especially in the EPC mode, and the general contractor needs to bear higher risks, so it is more necessary to accurately identify and effectively control the risk factors in order to further ensure economic and social benefits of the project.展开更多
