KDDI Corporation, Obayashi Corporation, and NEC Corporation announced that they used 5G to successfully construct common roads through real-time transmission and analysis of construction control data, in addition to simultaneous cooperation between remote control of three construction machinery (hereinafter referred to as “construction machinery”) and vibrating rollers equipped with automated operation systems.

The verification test was conducted from February 3, 2020 to February 14, 2020 with the provision of a part of the construction field of the Kawakami dam, with the aim of utilizing the system at general construction sites.

Through the use of 5G, the cooperation companies carried out remote-controlled drilling of three construction machinery such as hydraulic excavators, crawler carriers, and bulldozers.
The company also conducted 5G transmission of sediment volume and preparation result data using a real-time 3D laser scanner, and confirmed that a series of operations related to road construction can be realized by remote control and automation.

In the construction industry, labor shortage and skill succession due to the aging of field workers and a decrease in the number of young workers are urgent issues, and improvement of productivity by labor saving is urgently required. It is expected that this will lead to a reduction in the time to go to the site and a reduction in man-hours.

In the future, the company says it plans to use the technology applied in this demonstration experiment to continuously access multiple construction sites from remote construction management rooms in offices and other locations, and to enable one skilled worker to respond simultaneously to multiple construction machinery sites.
