RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $406,250.00 for Work Order No. 1112056 which includes all design, construction, change order contingencies, construction management and inspection for the SR 91 HOV Lane Project for the Arlington Avenue Undercrossing Main Replacement Project (Utilities Agreement No. 21636) — Phase V. BACKGROUND: The State of California Transportation Department (Caltrans) will begin work in mid-2012 on improving the SR 91 through the City of Riverside from Adams Street to University Ave. Caltrans is completing the design and will award for construction in mid-January 2012. Caltrans will also act as the Construction Administrator and the Riverside County Transportation Commission (RCTC) will provide funding for the utility relocations. Many water facilities owned by the City of Riverside Public Utilities Department will need to be replaced and relocated before construction can begin on the freeway. Utilities Agreement No. 21636 (UA 21636) with RCTC will accommodate the replacement of 544 linear feet of existing 12-inch cast iron water main. This work is being undertaken to accommodate the lowering of the road surface on Arlington Avenue at the SR 91 overcrossing. Staff has completed the design for the replacement of the water distribution main and associated facilities, Due to increased construction cost items including existing pavement thickness in excess of 18-inches, required night work by the Public Works Department and additional traffic control the construction cost is estimated to be $406,250. While this cost is in excess of the original estimate, it falls within the 125% range provided for in the UA 21636 with RCTC as previously approved by the Board of Public Utilities and City Council. Therefore, all costs associated with the relocation under the Utility Agreement will be 100% reimbursable by RCTC, FISCAL IMPACT: The capital expenditure of $406,250 includes all design, construction, change order contingencies, construction management and inspection, as summarized in the following table:
