The Study On Contractor Risk Management Of Road Engineering Project At Construction Stage

To contractors, road engineering project has a great deal of risk in the course of the whole operation, especially, at construction stage. If contractors don' t attach importance to the risk or handle the risk well, contractors will suffer enormous losses. So, risk is an important factor that determines success and failure of road engineering project. In order to avoid or reduce contractors' losses, . it is necessary to study road engineering project risk management.This paper considers contractor risk management of road engineering project at construction stage as the object of study, and studies the contents of every part including risk identification, risk measurement risk evaluation, risk handling and risk monitoring and controlling in the whole course of road engineering project risk . management in detail. In the part of road engineering project risk identification, this paper summarizes th.e table of road engineering project risk identification from various angles and positions. In the part of road engineering project risk measurement, according to the characteristics that loss probability, loss value and risk value have fuzzy feature and the characteristics that project risk manager' s subjective factors have effects on risk measurement this paper puts forward the method of fuzzy and utility risk measurement based on fuzzy theories and utility theories. In the part of road engineering project risk evaluation, this paper puts forward the method of fuzzy and utility risk evaluation based on the method of fuzzy and utility risk measurement. In the part of road engineering project risk handling, this paper analyses every tactics of road engineering project risk handling. In the part of road engineering project risk monitoring and controlling, this paper analyses every method of road engineering project risk monitoring and controlling. In addition, this paper takes A4 contract of liwen highway for example. According to the course of road engineering project risk management, this paperapplies synthetically relevant theories and methods of risk identification risk measurement, risk evaluation risk handling and risk monitoring and controlling, and analyses, handles, monitors and controls contractor' s risk of A4 contract of liwen highway at construction stage.
