Bridges and viaducts, from Ansfisa the operating instructions for the census

29/09/2022 – Uniformly apply the rules for the census and monitoring of existing bridges, viaducts, embankments and flyovers. It is the goal of operating instructions proposed by the National Agency for the safety of railways and road and motorway infrastructures (Ansfisa) and adopted by decree of the President of the Superior Council of Public Works.

The operating instructions implement the Guidelines for risk classification and management, risk assessment and monitoring of existing bridges, contained in the DM 1 July 2022 of the Ministry of Infrastructure and Sustainable Mobility (Mims).

Bridges and viaducts, guidelines for census and monitoring

Recall that the Mims guidelines were published in the Gazzetta at the end of August. The document represents a update of the guidelines launched in 2020 and dictates the timing for a series of actions that will lead to the knowledge of all the existing bridges and viaducts and of the conditions in which they live.

The guidelines provide for actions divided into several levels, from the census to the more in-depth analyzes, which end with the planning of any maintenance interventions.

Bridges and viaducts, the operating instructions for applying the guidelines

The operating instructions complete the guidelines, making application easier and more immediate. The experience of the Agency’s inspection commissions and the scientific collaboration with various realities, such as the FABRE consortium (Research consortium for the evaluation and monitoring of bridges, viaducts and other structures) contributed to the drafting of the instructions.

The objective of the instructions is in fact to arrive at uniform and standardized procedures which, starting from the census of the works, leads to the determination of a class of attention on the basis of which to activate the checks, taking into account the certification requirements of the Safety Management Systems.

Among the topics covered are the census of the works, the visual inspections and the defect cards, the analysis of the relevant risks, the classification of the attention class and the preliminary evaluation of the work.
