en.Wedoany.com Reported - Hitachi Construction Machinery Co., Ltd. (President and Executive Officer: Masafumi Senzaki) and Fukudome Kaihatsu K.K. (Representative Director: Masashi Oba) plan to conduct a joint remote construction demonstration test starting June 2026 at a construction site in Tosa City, Kochi Prefecture, using a real-time digital twin platform for a 20-ton class ZX200A-7 hydraulic excavator. This platform can reproduce construction site conditions in real time within a virtual world.
Against the backdrop of an increasingly severe labor shortage in the construction industry, remote construction is seen as an effective means to improve safety and productivity. Traditional remote construction primarily relies on camera images to operate construction machinery, requiring operators to visually observe the overall site conditions, including terrain changes and the movement of other machinery and vehicles.
In this demonstration test, Hitachi Construction Machinery and Fukudome Kaihatsu, in collaboration with multiple technology partners, will use a digital twin platform capable of real-time monitoring of the entire construction site to remotely perform excavation work with a hydraulic excavator, verifying the platform's effectiveness in enhancing safety and productivity.
The real-time digital twin platform developed by Hitachi Construction Machinery can collect and integrate data on 3D terrain, construction machinery, vehicles, and workers in real time, reproducing them in a 3D virtual world. This platform integrates remote construction, construction management, and site condition monitoring into a single user interface, contributing to improved safety and productivity.
The main verification items of the demonstration test include three aspects. The first is to verify the improvement in safety and productivity when using the real-time digital twin platform for remote construction. The platform collects and integrates real-time data on 3D terrain, camera images, and the positions of construction machinery, vehicles, and workers, enabling operators to perform excavation work from a comprehensive perspective. The second is to compare multiple remote construction modes: direct visual observation of the site, use of camera images only, and use of the real-time digital twin platform, to verify their respective effectiveness. The third is to verify remote information sharing and decision support, where site information visualized through the platform can be shared with remote operators and managers, providing a comprehensive perspective for decision-making and construction support.
Based on insights gained from this demonstration test, Hitachi Construction Machinery and Fukudome Kaihatsu will enhance remote construction functions, aiming to realize next-generation construction sites where humans and machines collaborate.
The demonstration test period is from June 1 to July 31, 2026, at a river dredging site in the Mochiishi area of the Niyodo River, Tosa City, Kochi Prefecture. Hitachi Construction Machinery is responsible for providing the real-time digital twin platform, leasing the ZX200A-7 hydraulic excavator, and overall coordination; Fukudome Kaihatsu is responsible for verifying the safety and productivity of remote construction; aptpod, Inc. provides the data acquisition cloud system and user interface based on the high-speed IoT platform "intdash"; Vectology, Inc. provides the "Accuvision" panoramic vision system to visualize images around the construction machinery; Unicast Inc. provides software to convert construction site terrain into 3D data. The scope of work involves remote excavation using the ZX200A-7 hydraulic excavator.
