– 65% Plans, Specifications and Estimate Submittal. Quincy will complete the preparation of the Draft 65% PS&E. The 30% Bridge and Approach Roadway Design together with input received during the completion of the environmental phase, will be the basis for preparation of the 65% PS&E. Preparation of the 65% PS&E will include completion of the following subtasks: Civil Design and Drafting Quincy will complete the approach roadway design, construction traffic control plan, and associated civil designs in accordance with the City Standards, AASHTO "A Policy on Geometric Design of Highways and Streets" and Caltrans Highway Design Manual (with City consultation). A full set of detailed approach roadway and civil plans will be prepared using City-supplied title blocks. The following plan sheets are anticipated for final design: • Title Sheet • Typical Cross Sections • Survey Control Plan • Layout and Profile (2 sheets) • Grading Plan (2 sheets) • Construction Details (up to 4 sheets) • Drainage Plan (2 sheets) • Construction Staging Plan (2 sheets) • Traffic Handling / Temporary Detour Plan (up to 5 sheets) • Signing & Striping Plan (2 sheets) • Erosion Control Plan Sheets (2 sheets) Bridge Design and Drafting Quincy will design the widened portion of the structure using Load Resistance Factor Design (LRFD) following AASHTO’s “LRFD Bridge Specifications 2012” with the California Amendments. For seismic design, Caltrans “Seismic Design Criteria (Version 1.7)” will be followed. Other references that Quincy will follow are Caltrans Division of Structures “Bridge Memo to Designers”, “Bridge Design Aids” and “Bridge Design Details”. The existing portion of the structure will be designed for seismic with a "no collapse" criteria per Caltrans Bridge Memos to Designers. A full set of detailed bridge plans will be prepared using City supplied title blocks. The following plan sheets are anticipated for final design: • General Plan • General Notes • Deck Contours • Foundation Plan • Abutment Layout (2 sheets) • Abutment Details (up to 3 sheets) • Typical Section • Girder Layout (2 sheets) • Girder Details • Deck Reinforcement (2 sheets) • Miscellaneous Details • Log of Test Borings Sheets The design will incorporate recommendations from the City and Caltrans and address issues identified during the public outreach process for the project.
