On some level, there’s no getting around the massive amount of material required to build a structure as large as Allianz Field. But within those constraints, stadium designer Populous, the construction company Mortenson and Minnesota United have done everything they can to ensure responsible use of steel — both new and recycled — at Allianz Field.
To begin with, the building was designed to be as open as possible, with its walls mostly composed of the PTFE fabric that wraps around the structural steel. This allowed steel overall to be conserved while still maintaining the strength and integrity of the building, reducing the total amount of steel needed by 100 tons.
