Continuous rainfall and seasonal changes to the Yamhill River threatened to wipe out our clients’ property. GEOMechanics was retained to provide geotechnical engineering services, which included performing a subsurface exploration, designing a retaining wall and new house foundations, and providing special inspections during construction.
The Solutions Unearthed
- Geomechanics prepared a geotechnical report with a soldier pile and lagging wall recommendation to address the slope stability issues. Additionally, we provided driven pile recommendations for the new foundations.
- Thirty-five foot long W12x53 soldier piles and two levels of 60-foot-long helical anchor tiebacks were installed to stabilize the area. Furthermore, the area located behind the wall was back filled, in order to increase the backyard area. The retaining wall was designed to support the additional load.
- Special inspection services during construction included review of submittals, tieback anchor testing, pile compression testing, and implementation of design changes.
