Attachment 'I to Amendment 2 -- Scope of Work <br />1.1, Complete a site visit to review conditions in the vicinity of the lower levee and 1-90 <br />bridge. <br />1.2. Gather and review existing survey, geotechnical, structural, flood, utility, easement, <br />and as -built data for the lower levee, 1-90 bridge, and City pathway through the bridge. <br />1.3. Assess the adequacy of existing survey and geotechnical data, develop a project <br />topographic basemap, and assess geotechnical conditions. <br />1.4. Complete calculations and prepare a 90% Design Package for a lower levee to 1-90 <br />bridge connection, this is assumed to involve reconfiguring the lower levee and <br />extending it/connecting it to the existing ecology block wall that extends through the <br />bridge along the City path. The concept is for the ecology block wall to serve as a flood <br />wall, attempting to maintain at least a 2 ft freeboard above the BFE. The design will <br />include reviewing geotechnical issues and consider current USACOE design <br />recommendations for levee-floodwall transitions/connections. <br />1.5. Prepare 90% project specifications and special provisions for a lower levee to 1-90 <br />bridge connection. <br />1.6. Prepare 90% materials quantities and construction cost estimate. <br />1.7. Prepare a 90% bid schedule. <br />1.8. Complete internal QA/QC review and submit the 90% Lower Levee to 1-90 Bridge <br />Connection Design Package to the City and/or County for review and comment. <br />1.9. Review City and/or County comments and prepare recommended responses, <br />1.10. Meet with the City and/or County to review comments, recommended responses, and <br />obtain direction on the final responses, <br />Task 1 Deliverables <br />Lower Levee to 1-90 Bridge Connection 90% Design Package (PDF format): <br />Topographical basemap and 90% design and TESC on 11"x 17" plan sheets. <br />- Standard details and specifications. <br />Special provisions and specifications. <br />Engineers estimate of probable project cost. <br />- Bid schedule. <br />Task 1 Assumptions <br />• Site visit involves two Aspect engineers for half a day. <br />• No new survey or geotechnical work is needed, or survey work is provided by the <br />County. <br />• No major utility conflicts requiring significant utility relocation design effort. <br />• Given existing infrastructure constraints, Aspect does not guarantee any particular <br />freeboard can be achieved at and through the 1-90 bridge. <br />One 90% design review cycle by the City. <br />No permitting or agency coordination support. <br />Reecer Creek Floodplain Mapping and Levee Certification Support Services Project 3 1 Page <br />
