Regular inspection of the stakeouts (GC structures, bridges, tunnels, connecting tunnels) carried out by the civil engineering company in opencast mining and underground mining.

Regular inspection of the stakeouts (GF structures, tracks, LC foundations) carried out by the railway construction company in opencast and underground mining.

-Sporadic control of deformations inside the tunnel (convergence profiles) and in the open air (settlements, landslides) -Control of movements (cracking) on existing characteristic structures.

-Systematic control of the temporary retaining structures and compliance with the monitoring plan drawn up by the general planner of the project (GILIG) and attached to these tender documents.
