2. REINFORCING BARS SHALL BE TWISTED M.S. BARS HAVING MINIMUM YIELD STRESS OF 414 N/mm2.

3. CASTING OF PILE SHALL BE CARRIED ON AS A CONTINUOUS OPERATION UNTIL THE ENTIRE PILE CASTINGIS COMPLETED BEGINING FROM THE HEAD TO END.

4 MINIMUM WEIGHT OF THE HAMMER FOR DRIVING PILE SHALL BE 1500KG.

5. HEIGHlOF FALL OF DROP HAMMER SHALL NOT BE GREATER THAN 1.5 METRE.

6. DRIVING MAY BE STOPPED WHEN A PENETRATION OF MINIMUM 5mm PER BLOW IS ATTAINED THROUGH THEDRIVING APPLIANCES AS MENTIONED ABOVE. THE LIMIT OF PENETRATION AS NOTED SHALL BE AVERAGE OF 3Ocm.

7. FOLLOWING PILE DRIVING RECORD SHALL BE KEPT IN AN ORDERLY FORM AND SHALL BE SENT TO THE DESIGNOFFICE TO VERIFY THE ALLOWABLE AND SHALL BE SENT TO THE DESIGN OFFICE TO VERIFY THE ALLOWABLEPILE CAPACITY BEFORE NEXT PHASE OF WORK.

8. CLEAR COVER FOR PILE AND BEAM= 75mm.

DUMPING OPERATION:

1. GEO BAGS IN LAYERS MUST BE DUMPED UNIFORMLY FROM ANCHORED AND PROPERLY POSITIONED DUMPING BOAT.

2. DUMPING OF GEO-BAGS SHALL BEGIN FROM THE TOE (END) OF THE APRON AND PROCEED TOWARDS BANK.

3. INSPECTION BY DIVING MUST BE DONE TO CONFIRM THAT NO RIVER BED AREA REMAINS EXPOSED AND GEO-BAGSARE PLACED UNIFORMLY

4. CROSS SECTIONS SHALL BE TAKEN WITHIN 12 HOURS AFTER DUMPING AT 1 5.00 METERS APART.

5. GEO BAGS MUST BE HANDLED WITH CARE, NO DAMAGED BAGS SHALL BE USED FOR ANY PART OF THE WORK.
