What I did: I made the detailed design and supervision of the installation by microtunneling and HDD, in very hard and abrasive quartzite-diorite rock, of a DN700 mm (28″) cast iron water pressure pipe – the work was split in two section, each one 80 m (265 ft) long. The borehole diameter was 800 mm (32″). A very challenging job for the extreme hardness and abrasivity of the rock. The water pressure pipe is part of a mini hydro-power plant in the Alps (Italy).

What I did: I made the detailed design and work supervising of the installation, by pilot tubing, of a DN600 (24 in) GRP pipe for the connection of two ventilation shafts in the new subway line C in Rome, Italy.
What I did: I made the preliminary and detailed design of the installation by microtunneling of a steel casing 72″ (1828 mm) 95 m long, along a 16% inclined drive, for the connection of two water tanks, at Nervesa della Battaglia for the main client ATS Srl, Italy.
