With the rapid development of my country's economy and the continuous expansion of the construction scale of basic civil and commercial facilities, there are some inherent risks in the process of project implementation. Due to the characteristics of many uncertain factors, claims have gradually been paid attention to in my country's engineering management field, especially in construction enterprises.
