On July 19th, 2016, the City entered into a contract with Christensen Brothers General Engineering Inc., for the Riverside Drive and 3rd Street Water Main Replacement Project WA 153, in the amount of $2,266,092.85.  Staff was also authorized to spend up to $226,610 for project contingencies and $125,000 for construction engineering services, bringing the total project costs to $2,617,702.85.


During the construction of the water main, unforeseen underground utilities were encountered, which are in conflict with the proposed water main.  City staff performed an analysis of these utility conflicts and determined that modifications to the scope of work were necessary.  These modifications require additional work to complete the construction of the proposed water main in Riverside Drive.  In addition to the unforeseen utility conflicts encountered in the field, City staff also authorized the extension of the water main replacement on 3rd Street from Lincoln Avenue to Washington Avenue.  The additional work for this extension was requested by the City’s Water Department staff, as this section of existing water main has been experiencing frequent water leaks.  The construction contract for the project includes competitive unit pricing obtained during the bid process which will be utilized for additional work.  



It is estimated that this additional work will require an increase in the project contingencies by approximately $225,000.  The additional work will bring the total project’s cost to $2,842,702.85. An additional appropriation from the Water Fund in the amount of $82,215.00 is required.


Therefore, it is staff’s recommendation to the City Council to authorize the additional work for the Riverside Drive and 3rd Street Water Main Replacement Project increasing the project’s contingencies by $225,000 for a total not-to-exceed amount of $451,610.
