CITY OF SANTA ANA SPECIFICATIONS PROJECT NO. 11 -6416 SEVENTEENTH STREET WATER MAIN IMPROVEMENTS 3. Prior to any shutdown of existing water system, Contractor shall have all necessary fittings and equipment on site to complete the water main tie -in or abandonment. 4. Shut down shall be scheduled within the selected bids allowable working hours and as follows: o Base Bid Night Work shut down shall be scheduled for between 9:00 p.m. and 3:00 a.m. o Alternate #1 Day Work shut down shall be scheduled for between 8:30 a.m. and 12:30 p.m. Contractor shall notify residents and businesses 48 hours in advance of shut down. Water shall not be shut off outside of times listed above except in an emergency. All work necessary to shutdown an existing public water main shall be coordinated by the Water Maintenance Division. Unless at the direct supervision of the Construction Inspector, under no circumstances shall the Contractor operate valves, hydrants, and other appurtenant equipment on the existing public water system. It shall be the Contractor's responsibility to coordinate the necessary shutdown schedules through the Construction Inspector assigned to the project. Scheduled shutdowns shall require sufficient time to allow water maintenance personnel to review, approve, and develop an appropriate Operation Program. Contractor shall coordinate shut down activities with the City of Santa Ana Water Resources Division a minimum of four (4) working days prior to any water main shutdown. The Contractor shall be responsible for maintaining all schedules current and coordinating all deviations, which may occur from time to time with the Construction Inspector. The City will make a concerted effort to isolate the system as planned with the Contractor. However, due to the age of the pipe and valves the Contractor should not expect an absolute shutdown and shall be prepared to employ pumping equipment in the event that an absolute shutdown cannot be achieved. The City Engineer shall judge the shutdown to be adequate for the tie -in to proceed as indicated on the plans and specified here in. The City will not be responsible for any delays due to system shutdown and isolation when an adequate shutdown can be achieved and no additional compensation will be allowed. When an extensive water main shutdown is required and an adequate shutdown cannot be achieved, the Water Department will determine what temporary service connections may be required. The Contractor shall furnish all necessary appurtenances (i.e. hose, piping, valves, and water trucks) and associated labor required to provide such temporary service. All piping and associated equipment used in temporary service connections shall be flushed and disinfected. All hoses shall be NSF approved. T -3u 23A -116
