A helical pile is an innovative deep foundation type that has numerous advantages over conventional piles. Asx000D
these advantages are realized in the foundation industry, this pile type is becoming increasingly common acrossx000D
Canada. Helical piles are now a preferred foundation solution for structures such as: low-rise commercial andx000D
residential buildings, power transmission towers, and modular buildings.x000D
It is widely accepted that the soil disturbance caused by helical pile installation is less than that ofx000D
conventional piles; however little research has been conducted to quantify this difference or to determine itsx000D
effect on pile capacity. Due to this research gap, the short-term capacity reduction caused by installationx000D
disturbance is difficult to predict and is often neglected. These deficiencies may lead to improper capacityx000D
estimations and under-design.x000D
Located in Leduc, Alberta, Twist Development Inc. (Twist) is a manufacturer of helical piles. It is importantx000D
to Twist, and the helical pile industry as a whole, that the understanding of helical pile installation effects isx000D
further investigated. The overall objective of the proposed research is to quantify the installation induced porex000D
pressure generation and its effect on the short-term capacity of helical piles. This research will lead to morex000D
accurate designs and greater confidence in this pile type across the foundation community.
