C^s,,DES. <br />p�<� `°y�9 KZTTZTAfS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />KITTITAS COONTI <br />• Amend Task 4 (Hydraulic Analysis and Reporting) to complete full hydraulic design, from 60% <br />through final design. Additional stream modeling and design is also required based on the <br />addition of the landowner access bridge and evaluations required for crossing options. <br />• Amend Task 5 (Environmental) to include additional work on permitting the new landowner <br />access bridge. <br />• Amend Task 8 (Civil Engineering) to include project redesign efforts and coordination with the <br />design team resulting from the need for a new landowner access bridge and irrigation <br />infrastructure. Jacobs will identify location options for the new structure and provide design <br />details sufficient for final PS&E. Jacobs will also provide a second plans package for COUNTY <br />forces to construct the access bridge. <br />Due to these late changes, the project construction date is pushed to fall of 2019. In order to allow for <br />engineering and environmental support during construction, we are amending the end date of the task <br />order to December 31, 2019. <br />The amendment will include the following specific changes: <br />Task 01— Project Management <br />No changes to the original task order. <br />Task 02 — Agency Coordination <br />Task 02 is amended as follows: <br />Jacobs will facilitate meetings with landowners, WDFW, and Kittitas County Conservation District to <br />determine project design needed to advance the project. This will include up to four meetings as a group <br />or facilitation with individual parties. <br />Task 03 — Geotechnical Investigations and Reporting <br />No changes to the original task order. <br />Task 04 — Hydraulic Analysis and Report <br />Task 04 is amended as follows: <br />Jacobs will now complete full creek realignment design in support of the final PS&E package <br />and provide hydraulic support for the addition of the new landowner access bridge. <br />1. 100% PSE Development: <br />a. Structural and hydraulic plans, elevations, details, and special provisions for both <br />the roadway culvert and landowner access bridge. <br />2. New bridge modeling <br />a. 2D modeling in support of the new landowner access bridge. Modeling is required <br />at each potential bridge location for the permit package. <br />3. Deliverables <br />a. Hydraulic base of design for new bridge structure <br />
