4.0 WORK PLAN <br />South Abutment <br />Given the information attained in. section 3of this plan the only alternative for driving pile is to <br />use an impact hammer for the South abutment. The current plan involves the South abutment <br />placed at a minimum of 5linear foot North of the existing 12 inch water main. We may be able to <br />push it a few feet further North but we will use 5 linear feet as a minimum. <br />The H -Pile will be drilled and or jetted in for the first 20 lineal feet before pile driving begins. <br />This will give us enough "driving" to establish the required bearing. <br />201800874 <br />The Sheet pile will need to be dug in and a static force applied for seating of the sheets as they <br />will end up with a piling toe depth 7 lineal foot below the existing 12" water main not allowing <br />for active pile driving to occur. <br />North Abutment <br />The North abutment will be driven with the vibratory hammer for both the sheet piing and the <br />H -Pile the vibratory hammer falls well below the acceptable criteria at this distance. <br />Note: <br />* *Grand Island Utility Department to be notified 72 Hours prior to any Piling Work. <br />MA 16N!�•A�t <br />:tits oc.9xit }t <br />� ti w <br />7 <br />
