details of outfall at river, and details of shoreline pipe protection and bank stabilization. The plan sheets will include overflow structure rim and bottom elevations,as well as pipe diameter and flow lines of pipes entering and exiting the overflow and outfall structures. These documents will be developed for use during the Conclusions Workshop,currently already scheduled to occur at the end of Subtask 7.3 activities, and will be incorporated into the Conclusions TM.The pre-design drawings will be to scale, however informal.They will be developed to a level sufficient for the City to understand the improvement and functionality of the rehabilitation design. Construction documents with detailed plans, construction details, and technical specifications for bidding and construction will be developed during subsequent phases of the project. Design concepts and draft work products will be reviewed by a senior quality control staff member. • Opinion of Probable Construction Costs:The Service Provider will prepare an AACE Class V OPCC for the rehabilitation design. The OPCC will incorporate quantities, unit prices and type of rehabilitation to reflect the design development to approximately 30% complete level. • Conclusions Workshop:An in-person workshop at the City of Everett office,currently already scheduled to occur at the end of Subtask 7.3 activities,will be used to discuss results of the pre-design efforts.The cost estimates and predesign documents will be presented during this workshop.The City and Service Provider will discuss permitting approaches and any issues, as developed by the City. An anticipated key outcome of this workshop is the agreement from the City that they would like to progress in design for subsequent phases of the project.This meeting will be attended by key City staff, including the M&O staff. The scope and budget for this activity assumes up to six(6) Service Provider team members shall attend this meeting.The meeting is anticipated to not exceed 4-hours. Workshop materials will be provided to the City prior to the meeting,for their preliminary review. (This Conclusions Workshop will include discussions of the results from both Subtasks 7.3 and 7.4 activities.) • Conclusions TM:The Service Provider will incorporate the results of Subtask 7.4 activities, including the pre-design documents and OPCC, into the Conclusions TM, as described above in Subtask 7.3. The Conclusions TM will be used as the basis of design for the detailed rehabilitation design tasks that are anticipated to take place in subsequent phases of the project. Assumptions: • The City has an easement or lease with WDNR for any portion of SR08 that extends onto State lands in the river. It is assumed that no temporary easements will be required for the SR08 outfall pipe section and any associated bypass routes. • City will provide existing plans, drawings and reports of the SR08 outfall pipe and outfall construction. • Subsurface conditions along SR08 and near its terminus in the river are unknown and rehabilitation design is likely to require assessment of subsurface soil conditions at the terminus of SR08 and offshore if extended into the river. Deliverables: • Conclusions workshop agenda and minutes (Same as Subtask 7.3) • Draft and Final Conclusions TM,as described above in Subtask 7.3.This TM will include the pre-design drawings, costs and permit matrix as attachments. (The Conclusions TM will include results from both Subtasks 7.3 and 7.4 activities.) 91F A A
