Rogers Pass Geotechnical Investigation
2017 – Rogers Pass, Glacier National Park BC
Client: Parks Canada
Project Scope
Future twinning of the Trans Canada highway was being considered. A geotechnical investigation was needed to assess the stability of substructures of the future roadway.
Methods and Solution
Tangiers was contracted to build nine engineered timber frame pad to facilitate a heli portable drill system to acquire core samples. The areas were between 32 and 45 degrees. One complicating factor was that there could be unexploded ordnance inside the proposed building sites left over from previous avalanche mitigation strategies (ie. 105mm Howitzer Shells). Tangiers, in concert with an EOD Military Specialist, searched for ordnance and safely secured the area.
Results
The engineered timber frame pads were constructed, utilized then dismantled. These areas were remediated to their original condition. The drilling program went faster than expected, due to the quality and ergonomics of the work platforms provided.
