FINANCIAL STATEMENT: ~/The cost of the Contract Change Order is $40,581.73. ~I{~ Sufficient funds have been budgeted for the project change f ~/- orders to date, including this proposed Change Order No. 9. DESCRIPTION: The City Council is requested to approve this contract change order (CCO) because the cost exceeds $25,000, which is the City Manager's limit of approval. This work on the San Ramon Road Phase IV project was to remove localized high spots from the existing pavement, repair existing failed areas in the existing San Ramon Road pavement, and to remove and replace the entire pavement section at the Shannon Avenue intersection. The work required pavement grinding, digout, and patching, as well as removal of the pavement at Shannon Avenue that had originally been scheduled to remain. The Shannon Avenue intersection was found to have an inadequate existing pavement section for the projected San Ramon Road traffic. If this work had not been done, the new overlay would have immediately deteriorated. The amount of failed pavement on San Ramon Road at Shannon Avenue was greater than originally anticipated during the project design (7,460 square feet as opposed to 500 square feet). This was partially due to the long FAU process through the State, and more pavement had deteriorated, and partially due to the fact that last year's overlay project stopped short on Shannon Avenue to avoid the removal of advanced signal detector loops. The bid price for pavement repair could not be extended for this work, as the quantity was only anticipated to be 500 square feet and had a high unit price. Therefore, it would not have been cost-effective to extend the bid price. The removal of the existing pavement section and replacement with 12" of asphalt paving in the old Shannon Avenue street section was approximately 1,600 square feet. The need for the structural pavement replacement at Shannon Avenue was an unknown condition at the time of bidding. The allowable contract days for this work are proposed to be extended by two days, which is the amount of time taken to do the work. Staff recommends that the City Council approve CCO No. 9 and authorize the Mayor to execute it. a:(sanramon4)\co\agstco9 ITEM NO.
