AL WAHDA 5/6 ARCHES

The 5/6 Arches at the intersection point of route 5 and 6 is already proving to be an iconic project and one that defines the new skyline of Qatar. Teufelberger-Redaelli’s contribution to this structure was manufacturing the cables, supplying the clamps, engineering the cable net installation and tensioning. The two arches are the tallest monument in Qatar, weighing more than 9,300t of steel.

The construction is part of the Lusail Express way, a 5.3km route connecting central Doha with Lusail city. The arch measures 147m in length, while the smaller arch spanning 140m in length. The cable net that links the two arches together has a pattern of valley cables and two groups of diagonal cables in opposite directions. The three-dimensional geometry of the structure was a challenge for the installation and tensioning of cables.
