Developing a Unified Framework for Data Sharing in the Smart Construction Using Text Analysis

Smart construction has become popular because it improves the efficiency of various activities on construction sites. Data sharing is crucial for multiple stakeholders to achieve smart construction management. However, a unified framework is absent for data sharing between stakeholders. This study aims to develop a unified framework for data sharing in smart construction at the project level. A two-pronged design method is adopted to develop a unified framework for data sharing in smart construction using text analysis and semi-structured interviews. Then, a case study is incorporated for the application of the smart construction management framework. The unified framework for data sharing is developed as a five-layer architecture, consisting of the primary layers of perception, transmission, database, application, and presentation. The function modules of the unified framework include on-site monitoring, personnel, safety, quality, material, digital file, environment, and supervision, supported by the implementation of BIM, cloud computing, and IoT techniques. As illustrated in the case study, the construction period can be saved by 50 days and the cost can be saved by 4.2% after implementing the proposed framework in the project. This study provides a benchmark for related studies on data management and collaborative innovation from various industries and stakeholders. Also, a useful framework has been developed by identifying the key elements, defining the primary functions, and developing the essential layers based on structural consistency.
