Important data to be recorded during installation of piling

Recording of data is of utmost importance during installation of piles as in case of any other foundation structure; since most of these details would not be available once the installation is completed. All the following data are to be captured suitably, and recorded in appropriate tables / formats.

1) Rig movement diagram.

2) Sequence of installation of piles.

3) Information about the piles.

1. Type of pile (working/test)
2. Pile number
3. Pile group number
4. Grid location
5. Pile diameter
6. Diameter of cutting tool used.
7. Specific gravity of bentonite slurry, with time of checking.
8. Local ground level / Casing top level
9. Length of permanent casing (liner) used.
10. Date and time of starting boring
11. Rate of penetration per meter
12. Depth and reference number of sample taken intermittently during the boring activity.
13. Date and time of completing boring
14. Time of conducting penetration test & ‘N’ value recorded
15. Pile bottom level
16. Depth of pile as recorded by sounding
17. Date and time of lowering reinforcement
18. Top level of reinforcement cage
19. Details of reinforcements
20. Measurement of reinforcement
21. Flushing start time
22. Flushing finish time
23. Concrete mix proportion & design strength
24. Concrete slump
25. Date and time of starting concreting
26. Date and time of finishing concreting
27. Pile top level
28. Cut off level
29. Total number of cubes taken
30. Identification number of cubes taken
31. Theoretical quantity of concrete required.
32. Actual quantity of concrete used

4) Cube test reports – 7th & 28th days.
