Research on Risk Sharing Mode of the Construction Project Based on Systems Theory

The construction contracts are the important basis of the project risk management and a reasonable contract system can effectively share engineering risks among various project participants. However, the current situation of risk management in China is not optimistic. Based on the analysis of the existing problems in the risk sharing management, the paper introduces Hall three dimension structure into the engineering fields and establishes a three-dimensional (contract dimension, procedure dimension and logic dimension) space structure of the construction project to elaborate the vital role of the contracts in the project risk management. Finally, the paper attempts to put forward a risk sharing mode centered on contract systems to make a reasonable and effective risk distribution among various project participants
