Geotechnical design and site supervision, accounting work.
Stabilization of a steep slope along via Richardette. At present, this slope has reached the limit of its stability and now poses a risk to the road (via Richardette). Similar stabilization work is needed on another slope downstream, running along the Gran Comba torrent. This slope has reached its safety limits due to water erosion from the torrent itself and shows evidence of several potential surface failures. The work on via Richardette consists in slope reduction by removing unstable soil-blocks and inserting soil-nail reinforcement with a cement grout sleeve. The work on the Gran Comba torrent involves using natural rock embedded into the slope. In-situ investigation, geotechnical design and site supervision have been carried out by North West Engineering S.r.l.
