This change order was negotiated by the City and Contractor to address additional work, not addressed in the contract documents, necessary to the completion of the project as described below: Due to unexpected flow test results the contractor was directed to revise the suction piping to attach to the %" outlet instead of the 2" outlet as recommended by Northstar Chemical Inc. Work for this item included additional testing of the system once completed. The final price is a result of negotiation between the City and Contractor on work necessary to complete the requested work. Staff recommends approval of Change Order #5 for $7375.66 plus tax. 0 Page 1 CITY OF PASCO PUBLIC WORKS DEPARTMENT CONTRACT CHANGE ORDER NO. 6 Project No: C7 -SE -1A-1542 Project Title: WWTP Caustic Soda Improvements Contractor: Industrial Constructors Inc.

This change order was negotiated by the City and Contractor to address additional work, not addressed in the contract documents, necessary to the completion of the project as described below: After continued testing of the system and discussions with all parties involved, Northstar Chemical agreed with the City's Design Engineer (RH2 Engineering) that a side outlet for the suction piping was needed to maximize the potential delivery of the caustic soda design. Northstar chemical has agreed to pay for the installation of the side outlet in the Tank. This change order reflects the work necessary for the City's Contractor to reconfigure the suction line piping to connect to the new side outlet. The final costs for this work are approximately $2,000 less than the original estimate provided. Staff recommends approval of Change Order #5 for $6,613.75 plus tax. 0 Page 1
