Specifications include, but are not limited to: Develop estimates of pipeline seismic vulnerability at the pipeline locations included in the study. Prepare conceptual upgrades and planning level cost estimates for those locations that are rated to be highly vulnerable to seismic effects. Develop a conceptual, long term approach to reducing the seismic vulnerability of the transmission pipeline alignments through the Seattle Fault and South Whidbey Island fault zones that will be implemented as the pipelines are replaced for condition-related or other non-seismic regions. Develop preliminary engineering (e.g., approach and sketches) and planning level cost estimates for the Cedar River Pipelines seismic upgrade through the Renton liquefaction area.
