Pleasanton PFAS Treatment & Wells Rehabilitation Project City of Pleasanton JDH Corrosion Consultants, Inc. 3 the plans and profiles for the new water pipelines prepared by Carollo for construction details and proposed pipeline materials and determine the suitability of the proposed materials based on the collected field and laboratory data. Task 3 – Final Design & Bid Documents 1. Prepare detailed design drawings, assuming a 30-year minimum design life. Prepare detailed installation drawings for corrosion control for selected project alternative (pipe and well sites) including appropriate stray current corrosion control, if needed. Review the proposed pipeline alignment for potential stray current problems. Determine if the pipeline will parallel and cross any gas or other water pipelines as each of these areas represent potential stray current problems. Design drawings will be prepared in accordance with the project standards for 50%, 95%, and 100% submittals. Design details will be prepared in AutoCAD Release 2018 format and electronically transmitted to Carollo for inclusion into the project plans. 2.
