We'll have more updates on Backstage on the Esplanade, but for now, our friends at Dominus explain what's happening on site, and give us a short lesson on tie backs.
Backstage is currently at the second level of tie backs, which are horizontal wires or rods that reinforce retaining walls for stability. The purpose of the wall is to excavate safely and to support neighbouring lands and structures. Tie backs are tension members set in the soil that hold the wall in a vertical position. Without tiebacks, the wall would not support itself, and would “fall” into the hole.
