The hydropower EPC project as a large complex project with various types of buildings carries risks that can cause failure or decrease in construction performance, especially quality performance and time schedule performance. EPC contracts with lump sum or fixed costs, where detailed planning is carried out after signing the contract in which one package with construction, then the planning stage has risk factors that affect the quality performance and time performance. A combination of quantitative and qualitative analysis is used as a research approach. Consultation and initial confirmation carried out for determining relevant risk factors to be studied and analyzed in the research model hypothesis using Structural Equation Model (SEM) with Smart-PLS software as a quantitative approach. The research model and risk response input from experts as a qualitative approach. The initial confirmation from the expert, it is known that 6 of the 8 initial variables with 36 out of 45 indicators are considered relevant for carried a hypothetical analysis of risk factors in the planning stage that affect the quality and time performance of the project. It's known that the variables of owner's necessities and requests, the scope of work and the engineering design output have a significant direct effect on quality and time performance. The communication and coordination factors have a significant effect on quality and time performance with the mediation of the engineering design output factors.
