THE CONTRACTOR SHALL PREPARE A SCHEDULE AND WORKPLAN THAT DESCRIBES PROPOSED SWITCHOVER ACTIVITIES. THE PLAN SHALL MINIMIZE UTILITY SHUTDOWNS. THIS SCHEDULE AND WORKPLAN SHALL BE SUBMITTED TO BOEING A MINIMUM OF 21 DAYS PRIOR TO CONSTRUCTION, AND CONSTRUCTION SHALL NOT BEGIN UNTIL BOEING APPROVAL IS GIVEN. PRIOR TO THE SWITCHOVERS, ALL CONSTRUCTION OR TESTING ACTIVITIES THAT CAN BE COMPLETED PRIOR TO THE SWITCHOVERS SHALL BE COMPLETED. 2. FOR THE WORK ASSOCIATED WITH THE LIFT STATION AND SANITARY SYSTEM, THE SWITCHOVER PLAN MAY INCLUDE A SHUTDOWN PERIOD OF UP TO 2 DAYS, SUBJECT TO APPROVAL OF AND COORDINATION WITH THE BOEING UTILITY SHUTDOWN COMMITTEE. ANY EQUIPMENT OR RESOURCES NECESSARY FOR THE SWITCHOVER SHALL BE PROVIDED BY THE CONTRACTOR. 3. THE FOLLOWING ORDER OF CONSTRUCTION ACTIVITIES ARE REQUIRED: 1. INSTALL SHEETPILE SHORING. 2. INSTALL TEMPORARY FORCEMAIN AND ENSURE OPERATION BEFORE SWITCHOVER. 3. CONSTRUCT NEW LIFT STATION INCLUDING WET WELL, INSTALLATION OF PUMPS, AND INSTALLATION OF ELECTRICAL POWER AND CONTROLS. 4.
