for the current project and for similar projects in the future. inside the tunnel “We’re talking about a pioneering system as simple as it is ingenious, which is very easy to operate and efficient at tackling one of the costliest, most challenging types of infra-structure: drilling and blasting tunnels with extremely long sections and lengths,” explains the expert. It can also be applied to conventional methods of tunneling. These tunnels can be as long, for example, as the eight kilometers of two-lane tunnels (plus rehabilitation of the existing tunnels) being constructed for the E6 Ranheim-Værnes highway in Norway, where laser-guided tunneling is helping to meet project deadlines (comple-tion planned for 2024) and streamline resources. That’s what you can achieve when you plan, develop, test, and roll out in-house technology designed for projects run by the company. In addition to being used in the Norwegian highway project, the system has also become a welcome member of the teams working on other road and railway tunnels, such as those of Requejo (2.4 km) and Padornelo (6.4) in Zamora, Spain; Olesa (6.1 km) and Tresponts (1.3 km) in Catalonia, Spain; and Line 3 of the subway in Santiago, Chile (6.7 km). All of them are advancing under the guidance of the emerald beam. CÓMO FUNCIONA
