Construction project claims are very important in project management. At present, domestic project claims are relatively weak, and construction companies should speed up the improvement of project claims related matters. Project claims in the construction market are important and effective means for contractors to protect their legitimate rights and interests, make up for project losses, and improve economic benefits. <br>This article mainly discusses the definition and important role of claims and counter-claims in project contract management, as well as the basis and conditions for obtaining claims in the process of contract management, and the correct calculation method for obtaining claims, and classifies claims through actual operations. Analyze the cause of the claim, and put forward the basic principles and countermeasures of claim processing based on this, and then analyze the actual case of the engineering claim, and complete the research of the whole thesis.

Construction claims are very important in project management. At present, domestic engineering claims are relatively weak, construction enterprises should speed up the improvement of engineering claims related matters. Engineering claims in the construction market is an important and effective means for contractors to protect their legitimate rights and interests, make up for engineering losses and improve economic efficiency.<br>This paper mainly through the project contract management on the definition of claims and counter-claims and the important role of the discussion, as well as in the contract management process of the basis for the acquisition of claims, conditions and the correct calculation of claims, through the actual operation of the claim classification, analysis of the causes of claims, and on the basis of the basic principles of claims processing and response measures, and then through the actual case of engineering claims to complete the whole paper research.
