RECOMMENDATION: That the Board of Public Utilities authorize an increase in change order authority in the amount of $1,500 to Work Order No. 1103139. BACKGROUND: On June 4, 2010, the Board of Public Utilities approved Utility Agreement No. 21731 with the State of Califomia Transportation Department (Caltrans) for improvements along the 91 Freeway from Adams Street to University Avenue. Construction will begin in late fall 2011. As a part of the project, several water facilities owned by the Riverside Public Utilities [RPU] will need to be relocated prior to construction, One of those water facilities is a non-operational well, co-owned by RPU and Caltrans, which needs to be destroyed. On January 7, 2011, the Board of Public Utilities awarded a contract to Palm Springs Pump, Inc. [PSP] to complete the well destruction at a cost of $32,760 with change order authority of $3,275. PSP began destruction of the well on March 9, 2011, and encountered a concrete pad to a depth of 8 feet where a depth of 2 feet was expected and bid. Consequently, the contractor was required to perform additional work as part of a change order which included excavating through concrete, removing concrete debris, and additional fees for proper concrete disposal. Staff requests an increase in change order authority in the amount of $1,500 for cumulative change order authority of $4,777, or 15% of contract amount, to accommodate the unforeseen extra work. FISCAL IMPACT: The total estimated cost for Work Order No. 1103139 is $58,500. Funds are budgeted and available in the Caltrans SR-91 HOV Project Account No. 6230000-470812. Fifty percent of the final cost will be reimbursed by Caltrans in accordance with the Utility Agreement, Prepared by: Kevin S.
