Unique Implementation Challenges of Installing Large Corridor Channel Realignments: Too Much Dirt, Too Much Water, and Not Enough Time


Large scale corridor realignments have their own unique implementation challenges. They require a substantial amount of excavation, usually within an existing floodplain; construction is driven by timelines dictated by environmental construction windows; and construction activities are often impacted by onsite water management. Ultimately, the channel and corridor are required to be stabilized prior to activating with flows.

While navigating through these challenges, their completion usually becomes the critical path towards further development stages beyond the corridor limits. Several approaches including ‘phasing’ construction over several construction windows and methods to generally ‘speed-up’ construction is discussed in the context of cost, feasibility, landscaping and stabilization, multiple-contractors, rework, and conformance.
