Power Grid Construction Project Cost Risk Factors Analysis Based on the Fishbone Diagram Theory

Combined with the characteristics of the power grid construction projects, based on the fishbone diagram theory, the paper gradually identifies the cost risk factors in power grid construction projects according to the project construction process of project decision-making and feasibility study phase, design and bidding phase, construction phase,and completion of final accounts and summary evaluation phase. The study provides a certain amount of reference for power grid construction project risk management and controlling grid construction costs.
