Abstract:As a project construction mode actively promoted by the government, Engineering Procurement Construction(EPC) mode has some advantages, but there are still many problems in actual operation process. By sorting out the second phase of Qinhe River ecological comprehensive treatment project, this paper points out the different problems existing in the project implementation process of owner unit, construction unit and design unit, traces the causes of these problems, and finally puts forward the solutions from different angles. Especially as the design unit, in addition to strengthening the communication with owner unit in the early stage of the project and selecting appropriate consortium partners, the key point is to establish an appropriate EPC project design mode and benefit distribution mode.
