Columbia River North and South Jetties Reconstruction Project

Location: Warrenton, OR
Client: Kiewit/US Army Corps of Engineers

Commercial and recreational use of the Columbia River increases dramatically during summer, a facet that required significant around-the-clock support for the extensive rebuilding of two Columbia River Jetties within the three-month window. Otak provided coordination and review of aerial photo base mapping, control recovery and performed random confidence checkpoints on as-built finish grade compared to the design grade. These coordination efforts resulted in a timely approval of the final submittal documents by the US Army Corps of Engineers.
