Contract Duration:

5 months

The scope of this project included the installation of 150+ stone columns (2.1m diameter and 9.0m to 11.0m depth) along 3 separate benches across a hill side.

The project was completed one month ahead of schedule as well as achieved other great milestones. Because of the location, ground improvement needed to be designed to stop the hill side from further slippage and therefore protect the 5 existing oil lines within the hill side. Vibration impact was also a concern both on the slipping hill side and on the adjacent live pipe lines.

Stone pile fill had to achieve a post compaction of 95% or better.
