Didital twin projects are underway in urban spaces to link real and cyber spaces. However, there are few efforts to accumulate data for digital twin in the construction field. By defining acquired data such as site progress and environmental information in the construction field, secondary uses such as safety management, quality control, and investigation of the causes of construction defects become possible. In this study, we consider and define data that can be obtained at the construction site as data used for three-dimensionalization of the construction site, and consider a digital twin based on three-dimensional point cloud data that can check the work progress during and after construction. In addition, the issues of data acquisition using multiple devices at construction site and visualization of the construction site on a digital space by superimposing each data will be clarified.
