Modern piling equipment is becoming increasingly larger and heavier to cater to the demand for deeper and larger diameter foundations required to take higher load capacities. Unfortunately, every year, piling rigs fall over or are subject to near misses due to inadequately prepared or maintained site surfaces. Every single one is preventable through better planning, a thorough understanding of the ground bearing pressures which a deep foundation piling rig will exert, and how to manage these pressures through the construction of a properly designed, installed, and maintained working platform.

Learning Objectives:

Participants will be able to:

  • Identify stability issues with foundation drilling equipment
  • Better understand ground bearing pressures 
  • Recognize the need for the project constructor to design, construct, and maintain safe working platforms for foundation drilling equipment
