THE CONTRACT IS MODIFIED AS FOLLOWS:
Description of Change:
Risers were used instead of post paving water and gas valve box when adjusting utilities
on the roads on Map Number 3. The cost of using risers is offset by a reduction in bid
items 17, 18, and 19.
Reason for Change:
The existing valve boxes were encased in concrete that was approximately 5 inches
thick.This was determined to be unforeseen to the contractor and would have resulted
in a significant increase in the respective unit costs. Using valve box risers is a common
practice in asphalt overlay projects even though they are not normally used by the City.
It was determined that the reduction in cost and traffic interruption justified their use in
this project.
Materials:
3 Manhole Risers
4 Water Valve Risers
3 Gas Valve Risers
Plans:
Map Number 3 was not changed.
Extension of Time:
The Time for Completion is extended 0 Working Days.
Equitable Adjustment:
This Change Order includes a significant change: None.
Sections 1-04.4 and 1-04.5 of the 2018 WSDOT/APWA Standard Specifications shall govern
this Change Order.The Work of the referenced Contract is modified to include the changes
detailed herein.The payment provided for herein shall constitute the complete and final
settlement for all costs of labor, equipment, materials, overhead, profit, permit fees, and all
other claims that may be made by the Contractor as a result of this change.
