건설공사에는 다양한 이해관계자들이 참여하며, 리스크와 클레임 및 분쟁이 발생할 수 있는 가능성이 높다. 분쟁은 비용과 시간의 손실을 발생시키기 때문에, 건설사 입장에서는 건설공사를 효율적으로 관리하고 수익성을 높이기 위해 건설분쟁을 사전에 예측하고 선제적으로 대응하는 것이 중요한 현안이다. 본 연구의 목적은 건설공사 조건에 따라 발생하는 분쟁의 유형과 분쟁유형별 발생확률을 예측할 수 있는 의사결정나무 기반의 건설분쟁 예측모델을 구축하는데 있다. 이는 분쟁을 사전에 예측하고 선제적으로 대응할 수 있는 기회를 제공한다는 측면에서 유용하게 활용될 수 있다. Construction projects have high potentials of claims and disputes due to inherent risks where a variety of stakeholders are involved. Since disputes could cause losses in terms of cost and time, it is a critical issue for contractors to forecast and pro-actively manage disputes in advance in order to secure project efficiency and higher profits. The objective of the study is to develop a decision tree-based predictive analytics model for forecasting dispute types and their probabilities according to construction project conditions. It can be a useful tool to forecast potential disputes and thus provide opportunities for proactive management.

Construction projects have high potentials of claims among a variety of stakeholders. Claims on their own are not disputes but they have high potentials leading to disputes if agreements are not made between parties due to conflicting opinions. In the event of the construction disputes between clients and contractors, it could give negative impacts to both parties and, to minimize or pro-actively manage construction disputes, the role of clients is more significant. The objective of the study is to analyze a level of associations between the types of disputes and causes of construction projects based on the association rule analysis, and to identify and discuss key characteristics and implications from client's perspectives. The study analyzes associations between the types of disputes and causes, and also identifies those with a high level of associations. It also presents the outcomes of more systematic analysis compared to descriptive statistics just based on frequencies. Through the analysis of the data cases, the study proposes the directions to resolve the causes of disputes from client's perspectives. It can assist to improve understandings of the relationships between the types of disputes and causes and to pro-actively manage the disputes of construction projects.
