What I did: I made the detailed design and project management of the installation of an high tension electrical infrastructure, performed by using dry directional drilling. All the installations were carried out in karstic rock (sandstone and limestone) with voids and caverns. Pilot bores were drilled by using a Down-The-Hole 4″ directional air powered hammer, equipped with a wireline Digitrack guidance system. Each borehole was reamed up to 550 mm (22 in). The overall installation length was 1.000 m (3,300 ft). Max crossing length: 220 m.
