Monitoring During Pile Driving
Monitoring During Pile Driving
(OP)
I would appreciate advice on monitoring options that a geotechnical engineer should take for a building located about 9 ft from the piles during driving about 60 ft steel pile pies in very soft silty clayey materials.

Do a very detailed pre-construction survey of the existing building and document all visible defects, cracks, anomalies and issues that could be affected or influenced by adjacent construction activity. Use still photos and video for the survey. Install crack monitors on existing cracks and clearly mark the ends of cracks to see if they propagate further after the activities.

Not sure where you are located, but these can be rented easily in the US and Canada.
Agree with BigH on the third-party observation. Have a testing laboratory experienced in this type of work do the whole thing.

Otherwise you could try OSMOS structural monitoring system. Used it before too and has continuous instant feedback on vibrations caused.

Then your periodic readings for each show the spacing of the marks, as well as the offset of the line at the crack, should that happen.
Locating these where they are not affected by other things, such as storage in front, etc. and can be read conveniently.
