THE CONSTRUCTION SYSTEM ASSOCIATING SENSING DATA WITH BIM/CIM 4D MODELS

Abstract

 In the construction site, labor-saving of the measurement work is attempted by the installation of IoT sensors. However, in construction sites where the shape changes every day, fluctuations in sensor data that do not change in measurement items due to changes in measurement items occur due to the replacement of the sensor, etc., which hinders engineers from judging countermeasures from sensor data and site conditions. Therefore, by associating sensor data with BIM/CIM models, we construct a system that can visualize the fluctuation tendency of sensor information with construction progress, and propose a method to improve the efficiency of measurement work by utilizing BIM/CIM model. By centrally managing the sensor on the BIM/CIM model, information on the sensor such as installation position and components can be easily shared, and by visualizing sensor data in conjunction with process information, engineers can visually grasp the relationship between sensor data and site situation, and make technical judgments quickly.
