ADDITIONAL COST ITEMS The Contract Documents will provide additional provisions for Extra Work which cannot be completely quantified at the time of bid. These work items will be included in the bid schedule as either Unit Price or Force Account line items in a separate schedule from the "Valley View Sewer System Adjustments" and will be billed according to the proportion of Extra Work associated with each specific utility. Two examples of such Extra Work items include "Potholing" and "Resolution of Utility Conflicts The potholing item will be used to assess potential conflicts between planned Project Work and existing District utilities, which were not accurately located during design, and the RUC item will track any impact that a conflict creates with the Project Work as bid. The District acknowledges that approval of the final contract documents, which includes these Extra Work items, signifies its acceptance of these items as a method of reimbursement up to the maximum approved by Tukwila's contract authority. The District will be given the option to perform any required Extra Work with their own forces, use one or more of these Extra Work items, or approve a Change Order to include the work in the City's contract for additional compensation. In either case any impact to the project schedule may be assessed against the District if the Extra Work delays the project completion date and the District could have anticipated and avoided the delay. The impact will be charged to the District at the rate to be determined by the Project Engineer on a case by case basis as allowed in the DOT Standard Specifications and applicable law.
