Abstract: Claims by international contracting companies are a common problem in international engineering project management.With the deepening of reform and opening up, the scale of Chinese and foreign enterprises going abroad to carry out international economic and technical cooperation and international contracting projects has gradually increased, and project claims have also increased.Some companies compensate losses through engineering claims,accumulate experience, and improve project management.However, in the actual project claim, if there are certain limitations in copying the claim experience and methods of other projects, the key to the claim is to master and flexibly use the basic principles and handling skills of the claim.Seizing the right time is the basis for the successful claim.Based on the author's many years of engineering management experience, this article discusses the specific application of international engineering contracting project claims based on the analysis of claims in international engineering project management for reference.
