Rock Fall Net Design

CLIENT: Canadian Railway Company

LOCATION: Fraser Canyon, British Columbia, Canada

Following a rock slide that closed a Canadian mainline railway, a railway company retained BGC to design and carry out rock slope stabilization.  This included a large scaling and trim blasting program, followed by rock fall modelling, and design and installation of a 100 m long, 3,000 kJ rock fall net system.  Particular challenges included:

• Difficult foundation conditions

• Multi-stakeholder issues

• Maintaining rail traffic flow during work

• Minimizing environmental effects of the scaling and blasting

• Worker safety.

At the time of installation, the net system was only the second installation in North America of this capacity.
