WE ARE AN ENGINEERING SCHOOL FOR TENS OF YOUNG ENGINEERS WHO WANT TO GROW DEVELOPING UNIQUE EXPERIENCES.
We developed a new App called Tunnel+. This App represents a new frontier in the services offered in engineering, as it provides its users with continuous support: Tunnel+ allows users to intelligently analyze at any given time and everywhere a complex system. Engineer Daniele Stocker states that “the planning and execution of underground works is extremely complex. Our experience teaches that in these situations the determining elements for the success of such works are understanding circumstances and quickly making the right choices. Tunnel+ has been created to best respond to these needs.” Engineer Davide Merlini, Technical Director Tunnels&Underground works highlights how “Tunnel+ is an innovative product, that allows us to accompany our engineering teams and our clients everywhere and at any time.”
“It doesn’t matter to be larger, quicker and smarter. In order to survive we must be able to adapt. In order to be successful we need to understand our clients’ needs and be able to develop unique and innovative solutions” conlcudes Roberto Schürch, Technical Director Smart Tunnelling Innovation at Pini Swiss Engineers.
