This study takes the secondary quality assurance work of a steel structure factory as an example, develops a mobile device APP and builds a database big data analysis system framework without writing code, so as to achieve on-site inspection with mobile device electronic form, and the qualitative and quantitative data analysis results are stored in a cloud-based relational database. In addition to viewing the inspection results at any time and exporting them to the owner's standard form format, it can also connect to the cloud database, create big data analysis, view statistical reports with mobile devices, and visualize the latest construction site progress and quality, occupational safety and health and other management information. It is expected to provide the construction industry with a low-cost and low-information technology threshold method to fill in the results of construction inspection, occupational safety and health inspection, material testing and other results in electronic forms, and store them in the cloud database to provide practical e-based big data analysis feasible solution.
