RECOMMENDATION:

Approve change order #1 to Harris Sand and Gravel, Inc. for Valdez Glacier Stream Training Dike and Riprap Revetment contract no. 1319 in the amount of $64,194

 

SUMMARY STATEMENT:

As-found survey of Copper Avenue performed by NRCS, preparatory to the execution of the training dike project, concluded that change in conditions had occurred.

 

In an email to the City Project Manager Scott Benda, NRCS identified the following quantity changes: “The quantity estimate for Bid Item 6, Excavation, Unclassified, has decreased 426 cubic yards to a new total of 10,969 cubic yards.  Bid Item 7, Earthfill, quantity has increased 2,248 cubic yards to a new total of 19,867 cubic yards.  Bid Item 9, Rock Riprap, quantity has increased 706 cubic yards to a new total of 16,290 cubic yards.” 

 

“These proposed changes were necessary due to continuing erosion and other stream changes that have occurred since the completion of the original design.”

 

The cost of the change order will be split among the City and NRCS
(City: $16,048.50 - 25% NRCS: $48,145.50 - 75%).

 

The addition of this change order maintains a contract value below the face value of the grant funding and City budget allocation.

 

This change order is necessary to complete the project as designed and is a discovery condition that did not exist at the time of design.
