The biggest advantage of EPC contract model is that it can shorten the construction period from planning and design to completion, and simultaneously validate client’s effective control of money. In this model the contractor is required to strictly manage the construction period and cost during the whole project lifecycle and responds to the risks in this process, as the client do in the traditional model; it’s also required that the contractor identify inner and outer risks in the procedure of tendering, contract negotiation and implementation and take precautions to ensure successful running of the project as well as their own interests.
