City of Pleasanton Phase 1A Recycled Water Distribution System Design Final Draft • preliminary road intersection profiles on Stoneridge at Hopyard, Chabot, and Willow; on W. Las Positas at Hopyard, Willow, Hacienda, Stoneridge and Owens; on Santa Rita Rd. at W. Las Positas,Old Santa Rita Rd. and Rosewood. • other preliminary key profiles including channel crossings and crossings of utilities greater than 20—inch • preliminary structural pipe support details for bridge crossing and culvert crossings, including abutment and beam penetration details • traffic control concepts for impacted areas(up to 8 sheets) • mechanical and electrical plans, single line diagrams and process and instrumentation drawings for the two flow meter and control valve stations Plan background mapping will show existing utilities (plan view and on any profiles and sections where available information indicates depth), and property lines. Drawings will be prepared using AutoCAD 2014 software on 22" x 34" full scale drawing format and RMC CAD standards. Pipeline plan drawings will be at 1" =40' full size drawing scale. Project details will be based on Pleasanton Standard details,as applicable,and supplemented with Consultant details. Consultant shall also prepare Special Provisions and supplemental technical specifications using Microsoft Word 2007, including edits to the City's standard front end sections and general provisions. The specifications will include the City's standard general provisions, table of contents, and relevant standard special provisions, along with supplemental draft technical specifications in CSI format for major items of work not covered in the City's special provisions. Consultant shall also prepare a preliminary list of bid items. Corrosion protection design will be in accordance with NACE standards with a design life of at least 30 years. Corrosion protection details and materials will be consistent with City requirements as implemented by Consultant's corrosion engineering subconsultant on previous projects. Electrical design work completed during the 50% design will include coordination of new utility services for the two flow meter and control valve stations. The stations will have a new, dedicated utility meter/service and internal electrical distribution system. Coordination with the serving utility (PG&E) will be provided during the design process to make PG&E aware of the project and obtain any necessary PG&E engineering requirements for integration into the Contract Documents. Early coordination with PG&E is necessary to avoid delays in construction due to utility lead times for engineering and materials that can sometimes be extensive. Consultant shall prepare a 50% PS&E construction cost estimate based on project development work to date. The estimate would be a Class 3 estimate as defined by AACE, International(Publication 18R-97). Consultant shall prepare for and conduct a 50% Submittal review workshop with the City to review the submittal package,resolve outstanding technical issues and address City comments on the 50%submittal. Task 5.4 Assumptions: • 50%PS&E will be a single package without designation of bid schedules • City will provide direction on number of bid packages based upon 50%PS&E review. • City acknowledges that Consultant will continue developing the design documents during its review in order to achieve the design completion milestone. • Controls and SCADA design are not included. • 50% design package will be based on the Design Report, which represents a design concept "freeze"point.
