After review,the City determined that the potential risks to achieve cleaning of the structure without structural impacts were outside the scope of the project. In addition,the decision was made that a full redesign to minimize the risk of such impacts would include critical path extensions and project delays,significantly increasing the timeline of the project,making this option impractical. The work associated with the cleaning of the 30"storm drain under Rainier Ave S.and S.Grady Way, per Bid Item A94, has also been removed from the Contract. Upon review of this scope of work,it was determined that the drain line is to be abandoned and filled per the Contract Documents.Therefore,cleaning the storm drain line at this section of the project is not necessary and once filled and abandoned per Bid Item A24,the City will still be provided the same end product upon completion. The revision of the Bid Item 94"Cleaning Existing Drainage Structure"eliminates the purpose for the west end box culvert modification(Bid Item 91),which was primarily designed to provide access to the culvert for cleaning. Therefore,this work was eliminated as well. Description of Change Delete the following the following scope of work: • Cleaning the 8-foot by 10-foot box culvert beneath Rainier Avenue S at Sunset Way(approximately 180 LF,Sediment 1-2'deep). • Box culvert modifications,west end,shall be as detailed on the Plans and in accordance with the requirements of Section 6-02 of the Standard Specifications and the Special Provisions. • Cleaning the 30-inch storm drain under Rainier Avenue at Grady Way(approximately 210 LF,Sediment 1-2'deep). Add the following scope of work: • Connect the storm lines from structures 140 and 95 to the existing structure of the box culvert at approximately STA 46+26, 129.63 LT,per Specification Section 7-05.3(3). Material No new material will be incorporated into the project as a result of this change order.
