“…New bridge constructions are often built from modern materials. They are often segmented and robust; therefore, although the inspections are conducted by qualified experts with long experience and valid authorization [5], they may be insufficient for an overall assessment of the health. Also, in order for an expert to conduct an inspection, they should be able to get close to the construction being checked.…”

The paper is concerned with the possibilities of long-term monitoring of constructions using modern wireless sensors and systems. There are currently many constructions under long-term monitoring performed by modern sensors. The monitoring enables an assessment of the current health of the construction or it can be used to recalculate and adjust the BMI models and subsequently evaluate the static and dynamic resistance of the construction. The sensors and systems installed enable the detection of hidden defects or newly emerging failures and damage. Using the results obtained from the monitoring of the construction, it is possible to predict and carry out a timely repair or maintenance of the construction, which will ultimately decrease the financial and time-related costs, ensure greater safety and prolong its lifetime and resistance.

The question of maintenance and monitoring of bridges gained attention during the last decade, especially in Italy, after some serious collapses. The first emergency phase was the census and the visual evaluation of the state of maintenance and preservation of existing heritage to highlight the critical conditions for security. For this reason, in 2020 the Italian Ministry of Transport and Infrastructure enacts Guidelines, based on a multilevel approach, which allows to save time and resources by deepening the analysis only on the bridges in the worst state of conservation. After two years of inspections, a lot of data had been collected. The data concerns both the geometrical/typological characteristics and the defectiveness of bridges. In the present work, the authors discuss the data of a sample of inspected bridges belonging to some Regions of the Italian infrastructural system trying to analyse them from a statistical point of view. The objective is to standardize an analysis methodology and apply it to a larger number of samples to obtain useful and significant information to refine the inspection procedure and, eventually, to educate algorithms for the a priori provision of the defectiveness level, suggesting a possible prioritization of the bridges to be inspected.
