What I did: I made the detailed design of the replacement by dynamic pipe bursting of a DN600 (24″) sewer concrete pipe with a DN800 (32″) HDPE pipe; I coordinated all the geological/geotechnical preliminary survey and I also made the detailed design of the bursting-expanding head, tailored shaped to work with a Tracto Technik TAURUS rammer (24″). The expander has an outside diameter of 1000 mm. The soil was sand with coarse to very coarse gravel.

What I did: detailed design and project management of the replacement, by pipe bursting, of concrete sewer pipes DN200-400 (8-16 in) and of the rehabilitation by UV-CIPP of concrete sewer pipes DN 250, 400, 600, 700, 800, 900 and 1000 mm (10, 16, 24, 28, 32, 36 and 40 in) for a total length of 2,5 km (1,6 miles) at the Florence American Cemetery of the WWII.
