Research On Risk Evaluation Of Electrical And Mechanical Construction In Low Density Residential Projects With General Contracting Mode

Since the 50’s of last century, risk management has been paid more attention by the corporate leaderships and project Executives from various countries, and its theory、method and tools have been enriched and developed in practice; For project construction, the risk management research based on the engineering characteristics and various constraint conditions has more realistic significance.Low density residential project is a kind of special civilian residential project, Compared with the ordinary civilian residential project, it has its own construction characteristics and special characteristics which need to meet the high-end customers with high quality requirements, also, the construction risk of mechanical and electrical engineering on such low density residential project is more outstanding; In order to control the construction risk, it is necessary that using the risk management theory and tools to identify、assess and analyze risk, and using risk control measures to ensure the project efficient operation in the construction process.This paper expounds the characteristics of low density residential construction and the construction characteristics of general contracting project, on this basis, the paper further analyzes the mechanical and electrical construction risk of low density residential construction, and discusses this kind of risk identification and analysis, finally, the paper establishes this kind of risk evaluation system which use comprehensive level analytic method as the main architecture. Take mechanical and electrical construction of the high-end villa project which developed by stages as a case, this paper provides the qualitative and quantitative analysis of construction risk based on Fixed price model(Includes all the negotiation), the risk assessment of the project and the application of the risk treatment measures. From the microscopic view, the paper tries to find a more objective and simple method to be used for risk management in practical engineering, and provides a reference for targeted risk management.
