Thursday 24th September
Hotel Grand Chancellor, Brisbane

The current TMR Geotechnical Design Standard and draft TMR specifications MRTS65, MRTS66 and MRTS68 all call for 100% of driven piles to be monitored at end of drive. The specifications also call for the results of monitoring to be correlated with dynamic pile testing (PDA) to determine input parameters for estimation of pile capacity using the Hiley Formula.

The Pile Driving Monitor (PDM) is a device which remotely measures set, temporary compression and velocity of concrete and steel piles using optically safe infrared laser technology. Through correlation with PDA testing, the PDM can also be used to estimate impact energy for each blow thereby significantly improving the reliability and accuracy of pile capacity estimates using a modified version of the Hiley formula. By measuring set and temporary compression a safe distance from the pile, the PDM also offers significant safety benefits to driven piling projects by removing the need for personnel to stand under working piling hammers to manually measure set and TC.

This half day workshop will cover all aspects of the field operation of the PDM and analysis of the data. Topics include:

  • Introduction to the PDM
    How does it work and what does it do?
  • Background/context around monitoring of piles at end of drive. What are the deficiencies in current practice and how does the PDM address these deficiencies?
  • Field use of the PDM
    How to set up and use a PDM in the field.
  • Correlation of PDM and PDA
    Derivation of input parameters for estimation of pile capacity using the PDM (Dynamic Reduction Factors and impact energy calculations).
  • Client and Designer Perspectives on monitoring of piles
    TMR & AECOM to present case study.
  • Use of PDM on TMR projects
    How should the PDM be used to satisfy the requirements of the Geotechnical Design Standard and draft Specifications to monitor piles.
