Recently, the economic system has faced a several unstable financial conditions (UFC) which affected the 
construction industries. As a result of the instability, this led to an increase in the number of claims during 
implementation. Therefore, the importance of studying the impact of (UFC) on management and settlement of 
claims has appeared. Also, the enhancement of an effective claim management system is highly needed. 
Therefore, this research attempts to qualitative and quantitative analysis of factors affecting the claim process. 
Qualitative analysis was performed by identifying and ranking the key factors influencing the management of 
claims for construction projects. Depending on the literature review and expert interview, 30 factors were 
determined and categorized into four major categories:1) human framework 2) claim characteristics 3) 
organizational issues ,and contractual issues. The questionnaire survey was conducted to get the opinion of 133 
participants, including contract managers, claim experts, and project managers. The data was analyzed 
statistically using (SPSS) software. Then, factors were ranked using the total importance index (T.R.I.I). Based 
on the results, the routine of public authorities ranked first. Whereas less-experienced parties come in the sconed 
of the overall rank. While the third factoris economic uncertainty and increasing inflation rates. Quantitative 
analysis of the factors influencing claims was performed using the fuzzy model. Thus, the fuzzy model was 
developed to estimate the percentage of affected cost increase resulting from the occurrence of critical factors. 
The model conducted a case study to verify the validity of the model application. Depending on the study and 
examination of the factors. This model attempts to provide a contract manager with a visually makes decisions by 
estimating the impacted costs. Contribute to measuring the extent of (UFC)damage to the claims process. This 
model is characterized by ease of application and addressing the ambiguity associated with the impact of factors 
arising from financial conditions. It also removes ambiguity about the interrelationship of factors with each other. 
Through this it is possible for the contract manager to develop an acceptable response strategy to enhance the 
chance of successful claims settlement and reduce the potential for disputes by avoiding or minimizing the impact 
of emerging factors
