Log Build focuses on improving the productivity and efficiency of the construction industry by visualizing the construction sites. At the moment, the quality and gross profit vary depending on the site supervisors. Also, they can not work efficiently enough to spare time to check the drawing of the building carefully. To address those issues, Log Build is creating a method of managing construction sites to reduce the number of trips to the site by 90%. Log Build develops "Logkun," a remote monitoring system, "LogWalk," a remote construction management system with a 360 camera, and "LogMeet" for video calling app specifically for meeting, checking, and inspection. As more and more existing industries are working on Digital Transformation(DX), the construction industry is no exception. The construction DX market is expected to grow to 791.2 billion yen in 2019 and 3.425 trillion yen in 2030.
