process has been changed to have FHWA oversight. Thus, WSDOT staff will no longer have any <br />role in the project. The new or deleted scope is shown below: <br />• Added Scope: <br />• The Civil Lead and Structures Lead shall attend the meeting. <br />Deleted Scope: <br />• WSDOT staff shall attend the meeting. <br />TASK 30 30% DESIGN SUPPORT <br />The original scope of work shown in this task requires an increased level of effort due to the <br />CONSULTANT being directed by the COUNTY to take on responsibility for the Structures and <br />Civil design for both the Story Creek and Lick Creek sites, and the increased level of hydraulic <br />design by the CONSULTANT described in Task 7. Additionally, the new alignment for Lick Creek <br />adds scope for a Landscape Architect to support grading and planting for the development of <br />restoration and mitigation plans. The supplemented scope is shown below: <br />TASK 10.1— Story Creek <br />• Added Scope: <br />• HYDRAULICS <br />♦ Assist CONSULTANT team to develop design details and special provisions. <br />STRUCTURES <br />Evaluate Preliminary Culvert Replacement Concepts of a four-sided precast concrete <br />box culvert directly with the COUNTY. As a result of this Preliminary Evaluation, the <br />four-sided precast concrete box culvert will be evaluated with regard to the proposed <br />length, width, orientation, and cost as pertains to: <br />Site hydraulics and scour conditions <br />• Culvert wing wall and head wall geometries <br />• Site preliminary geotechnical information <br />• ROADWAY <br />♦ Develop a preliminary Basis of Design Memo including project criteria, existing and <br />proposed geometrics, project constraints, design speed, clear zone, design elements, <br />design variances, design decisions, environmental permits, right-of-way, hydraulics, <br />maintenance of traffic (MOT), maintenance concerns, and any outstanding issues to be <br />resolved. Some of these elements may not be applicable for this project. <br />♦ Layout and evaluate up to two (2) horizontal and vertical MOT alignments to <br />accommodate the proposed culvert replacement. <br />♦ Develop the overall model of the project site. <br />♦ Develop 30% plan set with existing and proposed horizontal and vertical alignments for <br />roadway centerline and preferred MOT centerline, and right-of-way impacts (if any). <br />Scope of Service_Teanaway Hyd Imp—Amend 012018-04-19 <br />Page 7 of 19 <br />
