Remote Construction for Dam Embankment and Chimney Demolition

POINT

• Single operator manages embankment work and monitoring with multiple machines

  By simulating the entire embankment construction process using multiple remote-controlled and autonomous machines—while accounting for process constraints—Obayashi employed a Construction Management System (CMS)(*1) that automatically generates work plans, and a Fleet Management System (FMS)(*2) that coordinates multiple machines and vehicles with integrated safety features to manage automated operations. Additionally, AtlasX was used for quality control of the embankment.
  A single operator can manage the full dam embankment process—including loading, transport, and spreading—helping reduce manpower needs amid labor shortages and a decline in skilled workers.

  *2 FMS: Fleet Management System that coordinates multiple machines through input work instructions for synchronized operation

• Safe remote operation for chimney demolition

  Using the “Surrogate” system, which can be easily retrofitted to standard construction machinery, backhoes and carrier dumps were remotely operated for chimney demolition work.
  This allowed safe demolition from a distance, away from hazardous areas where falling debris make human entry difficult.
  Since demolition sites often involve dust, noise, and vibration, remote operation allows machinery to be controlled in a more comfortable working environment.
