Abstract

We analyzed the claims' factors in the public construction projects. According to the previous studies, construction claims and disputes complexly result from various causes. As researchers would define the claim by operational definition, they presented factors of a construction claim differently. Considering all things, the causes of a construction claim result from so many factors; that is institutional conditions, the practice of construction contract, and so on. This study presents the results of a Structural Equation Model (SEM) for describing and quantifying the fundamental factors that affect a contract claim between owners and contractors in the public construction project. Therefore, the purpose of this analysis is to identify the factors that affect a construction project, and to construct a model to predict a construction claim in public construction projects. Data for the model development were collected using questionnaire surveys which had been undertaken of project managers or contractors working on public sector construction projects. This analysis developed a model and the factors of a construction claim in public works were modeled by using the SEM. Process and project issues play a role in predicting the likelihood of the construction claim in public works. When these variables can be measured through surrogate variables. It is rejected the null hypotheses that the capability of owners and contractors, the external characteristics of the conducted project are related to the potential of claims in a significant level. However, the physical characteristics and complexity of projects and contract management are related to contract claim potential. From these results, we conclude that the potential of contract claims in the Korean public works is influenced by the process issue rather than the people issue.
