Machine carried out 37 hours of compaction work for British Columbia hydroelectric dam project
Trimble has completed its first test of a fully autonomous soil compactor on a live construction site.
The test was carried out at the Site C Clean Energy Project on the Peace River in northeast British Columbia using the Trimble Earthworks Grade Control Platform for Autonomous Compactors on a Dynapac CA 5000 soil compactor.
The fully autonomous machine completed 37 hours of real compaction work, operating ‘seamlessly alongside’ a mixed fleet of compactors, the rest of which were running the Trimble CCS900 Compaction Control System.
Data from all machines – both with and without an operator – was delivered using Trimble WorksOS Software, which is being used as the system of record for all compaction data on the jobsite.
“The Site C project was the perfect place to begin live testing of the fully autonomous soil compactor because of the cost and safety benefits autonomy will bring to large infrastructure projects like this in the future, and because of the willingness of the project owner and contractor to use new technology on their jobsite,” said Cameron Clark, earthmoving industry director for Trimble’s civil infrastructure solutions.
“We are pleased that this initial testing reinforces our philosophy that autonomous technology will play an important role in delivering a cheaper, faster, safer and greener future for the construction industry.”
The Site C Clean Energy Project is a BC Hydro hydroelectric dam being built in northeastern B.C. When complete, it will provide 1,100 megawatts of electricity each year, enough to power 450,000 homes or 1.7 million electric vehicles.
Prime contractors include ACCIONA Infrastructure Canada Inc. and Samsung C&T Canada Ltd, among others. The role of ACCIONA and Samsung includes construction of an earthfill dam, two diversion tunnels and a roller-compacted concrete foundation for the generating station and spillways.
“Autonomy plays an important part in Samsung’s vision of a more sustainable future, so it was thrilling to have a fully autonomous compactor being put to the test alongside our fleet of equipment with an operator on this project,” said Yunki Kim, group leader of the Construction Automation Team at Samsung C&T.
Trimble will continue with extensive assisted testing through the rest of 2023 and into 2024 before making Trimble Earthworks for Autonomous Compaction available to select customers for beta testing.
“This is just the first step in what will be a diligent and careful testing process, but it’s an important step and we are highly encouraged by the results,” said Aaron Thompson, vice president, autonomous solutions, Trimble. “We look forward to fine tuning this technology as we move through testing, and to helping propel the industry forward as we work toward a more autonomous – and therefore more sustainable – future.”
