Terracon posted a new blog post about a unique hybrid soil nail and anchored soldier pile wall excavation support system for the Tower 12 Building project in Downtown Seattle. The project involves a 60-foot deep excavation for underground parking, but the west side of the excavation was adjacent to an existing 20-story building with three levels of below-grade parking. The hybrid system involved tightly spaced soil nails in the upper portion of the excavation wall and steeply-inclined, high-capacity ground anchors (200 kip) to support the lower portion.
