McDonald & Ross Const. Ltd. installed 219.1mm IP gas pipeline crossing the Seymour River in North Vancouver, BC. This work was extremely environmentally sensitive therefore the Department of Fisheries was involved in this project as well as an Environmental Monitor and top level interest from BC Gas Utility Ltd. The work included in-stream workspace isolation, backfill; apron replacement and restoration of river bed; restoration of river banks including armourment placement and riparian vegetation rehabilitation.
