"The Palm Islands" are three gigantic construction projects, that have been labled as the "Eighth Wonder of the World". Off the coast of Dubai, the islands are man-made and have the shape of huge plam trees and "palm branches", protected by a semicircular breakwater.
The construction works have advanced the most on "Palm Jumeirah" with a Herrenknecht AVND2500AH as a part of the team. Through sand, coral and limestone the machine excavated two tunnel, each of a length of about 700 meters. Inside these tunnels, utility lines for electricity, telephone and water were to be installed running in a slight curve from one of the palm branches to the breakwater.
