Tieback Tool, Recovered
- Description
- Recovered rusted steel tieback tool.
- Historical Notes
-
More than 1,400 tiebacks—high-strength temporary anchors made of steel cable encased in pipe—were drilled through the slurry wall down into bedrock to brace the wall. When the construction of the towers began inside the bathtub, the building itself took over the tiebacks’ support function, and the cables were severed.
This tool was found near the slurry wall during the excavation of the World Trade Center site after 9/11. It is believed to have been used during the original construction of the World Trade Center as an aid in setting the tiebacks into place.
