WORKING REMOTELY

摘要

The 2,500m-long tunnel was constructed partially through the most recent volcanic deposit in BC, including a zone of unconsolidated soils. An originally unplanned grouting program was designed and implemented to manage unexpected water inflows and consolidate largely unknown materials, which differed greatly from deposits encountered during various initial project investigations. From challenging geology, to some of the strictest environmental requirements faced by a run-of-river project in the province of British Columbia, the owner, engineer and contractor collaborated as a team to come up with solutions and manage each, and sometimes daunting challenge. The tunnel was delivered in time for commercial operations and overall considered a great achievement and success.
