W A T E R E N E R G Y L I F E RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: September 21, 2012 ITEM NO: 5 SUBJECT. CONSTRUCTION OF THE EMERGENCY PAVEMENT REPAIRS FOR THE WATER PIPELINE BREAK ON NORTHBOUND VAN BUREN BOULEVARD BETWEEN MORRIS STREET AND DOOLITTLE AVENUE ISSUE: That the Board of Public Utilities consider approval of the expenditure in the amount of $995,000 for all design,construction,construction management and inspection costs to construct the Emergency Pavement Repairs for the Water Pipeline Break on Northbound Van Buren Boulevard between Morris Street and Doolittle Avenue. RECOMMENDATION: That the Board of Public Utilities approve the expenditure of $195,000, which includes all design, construction, construction management and inspection costs for the Emergency Pavement Repairs for the Water Pipeline Break on Northbound Van Buren Boulevard between Morris Street and Doolittle Avenue. BACKGROUND: On Saturday, August 18, 2012, the existing eight-inch diameter fire service which feeds 6667 Van Buren Boulevard ruptured, causing significant flooding and damage within the northbound lanes of Van Buren Boulevard between Morris Street and Doolittle Avenue(Attachment 1). The water undermined a substantial portion of the roadway and saturated the bedding material of the adjacent sewer main,causing the pavement to heave up and crack, creating an uneven driving surface for a significant distance along the traffic lanes (Attachment 2). Fortunately, City crews were dispatched immediately and were able to safely divert traffic and repair the broken pipeline without further incident. Staff believes that a leaky one-inch service lateral saturated the underlying soil to such an extent that the soil was no longer able to distribute the weight of vehicles above,creating excessive loading on the eight-inch fire service, causing it to fail. Staff coordinated with the Public Works Department to identify the extent of pavement repairs needed, and prepared construction drawings accordingly. Construction bids were solicited from Riverside Public Utilities' Paving Contractor Panel over an accelerated bid period, and the notice to proceed was issued to the paving contractor on Friday, August 24, 2012. Due to the emergency nature of this project, the City's usual competitive procurement procedures for contractor services were waived by the Purchasing Services Manager, in accordance with Purchasing Resolution 21182,Section 201(a). The City Charter also provides,in Section 1202(b),that the Public Utilities General Manager and the City Manager can approve emergency expenditures in excess of$100,000 if there is an "urgent necessity to preserve life, health or property", so long as the General Manager takes the expenditures to the Board of Public Utilities for approval as soon as practicable thereafter, The Public Works Department will follow up with miscellaneous concrete and landscape irrigation repairs needed to complete the project.
