Port of Tillamook Bay Railroad Restoration

PBS provided geotechnical and natural resource professionals to Port of Tillamook Bay Railroad properties to assess storm damage and pre-storm conditions along approximately 26 miles of rail section, 4 bridges, and 118 affected sites. PBS’ geotechnical work included evaluation of slope stability and initial geotechnical engineering damage assessments of the infrastructure including tracks, bridges and tunnels. PBS’ natural resource work included identification of natural resources (wetlands, streams) present at each site and an evaluation of potentially required local, state, and federal permits, including required studies or reports, based on the proposed repair.

PBS utilized two teams of four professionals each in both geotechnical and natural resources to assess, document and report about 140 sites identified to be of concern along the railway. Additionally, six bridges were evaluated from a geotechnical damage assessment perspective. As the sites were visited and field data gathered, senior consultants with PBS performed data analysis, interpretation, and assembly of final reports for submission to the prime consultant.
