The Contractor may need to excavate additional test pits during the course of work to assess tainted soils which would need to be exported. This Change establishes pay items for the work to excavate test pits for the evaluation of tainted soils. Because petroleum tainted material cannot be accepted at standard export sites or disposed of under the original unit prices in the proposal, a new unit price has been established to cover the costs associated with the disposal of petroleum-tainted soils. Equitable Adjustment: This Change Order does include an equitable adjustment per Section 1-09.4 of the 2022 WSDOT/APWA Standard Specifications. See attached.
