Although several studies have evaluated effective factors for conflict occurrence, researchers have developed few methods of determining preventive capacities and determining preventive measures on the basis of an analysis of chain of risks that cause conflict. The purpose of this paper is to devise a mechanism for conflict prevention by evaluating chain of risks that cause conflict and different conflict types.

Efforts centered on facilitating the prevention conflicts through analyzing the effects of chain of risks on change causes, decomposing the mixture of conflict types in each conflict and determining the contribution of each conflict type to conflict creation.

The paper expands the existing body of knowledge on conflict management through the determination of complex relationships, namely, the relationship between conflict causes and project parties and the coherence between project parties and conflict types.

A practical example is analyzed to demonstrate the proposed approach capabilities. The results showed that using the developed approach to determine conflict type can serve as a means of control in projects and the developed approach can be incorporated into construction contracts as a conflict resolution mechanism. This paper presents an understanding of complex relationships among the chain of risks which cause conflict, the important players in conflict management process and different conflict types. It also provides a basis to select an effective management method for each conflict.

Although several studies have aimed to present models to predict conflict outcomes, fewer methods have been developed to analyze conflict manageability and provide management strategies based on prediction models. This research pitches into the manageability analysis of conflicts occur during the implementation of a proposed change in construction projects. In this way, a framework has been developed by defining two parameters: the predictability index and the preventability index.

Within this framework, the predictability index determines how many outcomes of the prediction model can be used for conflict management based on the degree of clarity. The preventability index demonstrates how preventive measures for conflict management can be identified. Eventually, three preventive measures can be determined: (1) identifying weaknesses of decision-making patterns and organizational culture, (2) identifying events that may be prevented using soft skills and (3) identifying differences among similar change-implementation scenarios and evaluating causes of the differences. To demonstrate the capabilities of proposed framework, a practical example has been analyzed.

The results show that the behavior of the project parties can be psychologically analyzed, and psychological conflicts can be distinguished from technical conflicts. Moreover, identifying the weaknesses of parties' decision-making patterns and their organizational culture is the most effective measure to prevent the conflicts.

This research contributes to the construction body of knowledge by quantifying the predictability and preventability of conflicts between the project parties in a construction project based on: (1) the certainty level of the conflict occurrence and (2) the level of alignment between predicted outcomes of the conflict occurrence and the issued change request and/or change order.
