WATER 1 ENERGY I LIFE PUBLIC UTILITIES RIVERSIDE PUBLIC UTILITIES Board Memorandum BOARD OF PUBLIC UTILITIES DATE: DECEMBER 11, 2023 SUBJECT: CONSTRUCTION OF THE ELEVENTH STREET WATER MAIN REPLACEMENT PROJECT — APPROVE THE INCREASED EXPENDITURE OF $190,000 FOR WORK ORDER NO. 2217506 FOR A REVISED WORK ORDER TOTAL OF $776,000 ISSUE: Consider approval of the increased expenditure of $190,000 for Work Order No. 2217506 for a revised total of $776,000 for all engineering, construction, paving and construction contingency costs for the Eleventh Street Water Main Replacement Project. RECOMMENDATION: That the Board of Public Utilities approve the increased expenditure of $190,000 for Work Order No. 2217506 for a revised total of $776,000 for all engineering, construction, paving and construction contingency costs for the Eleventh Street Water Main Replacement Project. BACKGROUND: The Riverside Board of Public Utilities approved the construction of the Eleventh Street Water Main Replacement Project on August 22, 2022. The pipeline work started in January of 2023 by Riverside Public Utilities (RPU) Water Division field forces and was completed in April 2023. The project entailed the replacement of approximately 1,250 feet of existing 4 -inch cast iron water pipelines from 1920. Water pipelines are ranked as high priorities for replacement based on their leak history, age, and size. Using RPU's Paving Panel, All American Asphalt was selected to conduct the final trench paving. DISCUSSION: The increased expenditure for this project is twofold: Higher-than-expected paving work costs and additional construction costs due to excessive soil moisture. On December 28, 2022, three bids were received from RPU's Paving Panel to repave the pipeline trenches for this project in the amounts of $255,635 (All American Asphalt), $344,785 (R.J. Noble Company), and $421,415 (Hardy and Harper, Inc.). All three bids exceeded the amount budgeted of $150,000 due to higher-than-expected costs for furnishing and installing the asphalt pavement from what is believed to be related to industrywide increases in paving prices from the inflation of material, trucking, and labor costs.
