Soldier piles with tiebacks
At 8777 Washington, the named systems were soldier piles and tiebacks. In an anchored soldier pile system, the piles, anchors, and connections act together to carry the retained-ground loads at the planned excavation stages.
Pile positions and installation access
On a new project, existing foundations, utilities, drilling clearance, and ground conditions affect the pile layout. The wall line must fit the excavation geometry and the space where the contractor can install the support.
Support as excavation advances
A soldier pile wall's lagging and bracing need to follow the excavation sequence. The design uses the proposed depths, loads, geotechnical recommendations, and construction access to establish how the wall will be supported at each stage.
