Dakota-Federal 42X-36 Well Pad Stabilization-Video

Video Transcription

Video Summary

Braun Intertec and VITE stabilized a North Dakota well pad affected by historic landslides and soft, water-sensitive soils. Monitoring detected accelerating movement in 2022, including elevated pore pressure in a deep lignite layer. Engineers used site investigations and numerical modeling to design a 705-foot anchored soldier-pile wall, with deeper piles through the lignite layer.<br /><br />During construction, heavy rain reactivated the slide, shifting three installed piles several feet. The team quickly drove 98 temporary steel piles along the slope, monitored movement, and resumed construction from a safer bench. The wall and anchors were completed by August 2022.<br /><br />Post-construction surveys show the wall remains stable. Inspections have found cracking and creep downslope, but the temporary piles appear to limit movement in the area they reinforce. Monitoring continues to track performance and distinguish slope movement from any impact on the wall.
