Abstract
This study explored deficiencies in data governance frameworks within the architecture, engineering, and construction (AEC) sector, focusing on their alignment with the operational and technological requirements for managing big data. Semi-structured interviews were conducted with AEC professionals using a qualitative generic inquiry approach to examine the challenges of data integration, quality assurance, security, and alignment with task requirements. The thematic analysis of the interview data identified persistent issues, including fragmented data integration, inconsistent data quality, inadequate security measures, and a lack of task-specific governance tools. This study applied Task-Technology Fit (TTF) theory to evaluate the alignment between existing governance frameworks and the dynamic demands of AEC projects. The findings demonstrated that misalignments in governance practices impede decision-making processes, reduce operational efficiency, and increase project risks. This study extended the application of TTF theory by emphasizing its relevance in designing governance frameworks that better support big data management in the sector. This study contributes to the academic discourse by underscoring the critical role of tailored governance frameworks and proposing practical improvements for industry stakeholders. Recommendations include standardizing data formats, enhancing quality assurance practices, strengthening security protocols, and developing task-specific tools. The study also identified opportunities for future research, such as exploring the integration of emerging technologies, such as blockchain and artificial intelligence, expanding the geographic scope, and adopting mixed-methods approaches to validate findings. By addressing key deficiencies in data governance, this study provides actionable insights for improving project outcomes and operational efficiency within the AEC sector, while establishing a foundation for future investigations into innovative governance strategies.
