The Ledcor-Haisla Limited Partnership (LHLP) was awarded the contract for the early civil work to construct the Liquified Natural Gas (LNG) facility in Kitimat, BC. The scope of this project included the clearing and grubbing of the proposed plant site and the construction of creek and waterway diversions for Canada's largest habitat offset project.
To help protect these sensitive waterways, the habitat offset included the construction of side channels for Kitimat River, Anderson Creek, and Moore Creek, in addition to realignment of Anderson Creek and Beaver Creek.
Conscious of seasonal environmental factors such as water windows (provincial in stream work windows) and migratory bird nesting seasons, LHLP implemented creative construction and scheduling solutions to complete the work. Solutions included diverting Anderson Creek into the existing Beaver Creek to complete the Anderson Creek realignment channel and the Anderson Creek Bridge. This required the installation of a super sac diversion berm alongside fish salvage support. Furthermore, when the client requested LHLP to divert the existing Beaver Creek off the plant site to accelerate the schedule, LHLP devised a plan to divert Beaver Creek into Anderson Creek Pond 1 through a temporary overflow channel.
LHLP completed the work scope within tight schedule constraints to allow for other work to begin, such as the construction of the Heavy Haul Road and the Heavy Haul Bridges.
