This research explores the potential of leveraging unstructured data from construction supervisiondocuments, which contain detailed inspection insights from independent third-party monitors ofbuilding construction processes. With the evolution of analytical methodologies, such unstructureddata has been recognized as a valuable source of information, offering diverse insights. The studyintroduces a framework designed to assess cost performance by applying advanced analyticalmethods to the unstructured data found in final construction supervision reports. Specifically, keyphrases were identified using text mining and social network analysis techniques, and these phraseswere then analyzed through binomial logistic regression to assess cost performance. The study foundthat predictions of cost performance based on unstructured data from supervision documentsachieved an accuracy rate of approximately 73%. The findings of this research are anticipated to serveas a foundational resource for analyzing various forms of unstructured data generated within theconstruction sector in future projects. |
