Technical features for quality procedures in tunnelling

The particulat and variable context in which tunnel constructions are built in claims for the detailed knowledge of the natural environment, the suitable design approach, the rigorous construction technique. Quality procedures in tunnelling should help to drive along these steps, also by means of assessment and monitoring methods, taking into account that the aims are the respect of expectations in terms of time, costs and overall use of the underground construction. The various phases, from planning to operation, should follow guidelines for operating staff, in a coordinated project organization and with the due exchange of knowledge: experience, goog contracts and responsibility can be the keys for the success, thus hopefully limiting the failure events and the controvercies.
