This change order was negotiated by the City and Contractor to address various changes in condition. The City was notified of a change in condition for the following items: During the tie-in to the 30" Steel Water Main, the contractor spent a significant amount of time on dewatering the line and dealt with additional water coming from the pipe throughout the tie-in process. It is reasonable to expect that dewatering a 30" main between the existing valves is a significant process, and that the time and effort to do so, should have been a consideration when bidding the project. However, through negotiation, the City agreed to pay half of the costs incurred for additional dewatering, due to excessive length between valves for this section of water main. The cost for this work is $803.17 plus tax. The location of the 24" Cap in 12"' Street was revised due to concerns of disturbing the existing lead joint Tee. The revised location for the cap created a concern that stagnent water may develop in the 24" dead end pipe segment, and Water Operations Staff requested that a Hydrant be installed on the end of the 24" line segment. The additional hydrant will provide an added benefit of having a hydrant in a closer proximity to the existing chlorination room. The cost for this work is $6,007.99 and includes $621.39for labor, $4161.48 for materials, and $438.14 for equipment. The cost for this work is offset by one 24" Cap which will not be installed, for a savings of $1,047.69. The net additional for this item is $4,960.30 plus tax. The existing water main in 1 e Street is a 21" instead of a 24" as shown on the plans. This requires the installation of a 24'x21" Reducer to complete the connection. The cost for this work is $3,181.17 and includes $814.27 for labor, $1,371.69 for materials, $424.48 for equipment.. The total cost for this change order is $9,992.33 which includes a contractor markup to cover profit and overhead of 22%. The City is expecting a cost savings of $1,047.69 in uncharged bid items for a Net increase of $8,944.64 to the final contract price. Staff recommends approving Change Order #2 for $9,992.33 plus tax. No additional contract days were requested in association with this change order. • Page 1 CITY OF PASCO PUBLIC WORKS DEPARTMENT CONTRACT CHANGE ORDER NO.3 1 Project No: CPI;I�WT-2R-14-02 Project Title: Butterfield WTP 244n Valve Replacement Contractor.
