Integrating smart construction objects and augmented reality for onsite assembly of modular construction

We designed a novel hardware system that combined AR, RTK and i_Core, to be utilized in the assembly stage of modular construction. The system we proposed made it clear to divide the work in the module assembly stage and helps the site manager to set rational and better labor assignments during the onsite assembly stage.The site manager uses an AR device to monitor the module in AR, then conduct the operator to control a tower crane to move and rotate the module to install it. The process can be visualized on Web-BIM. And a case study has been done.
