Analysis and prevention

In many industrialized countries, maintenance of the existing infrastructural network is a necessary process, and in some cases, the lack of such maintenance has led to critical situations, at times with tragic outcomes. The absence of an industrialized process results in delays, planning difficulties and a significant increase in repair costs. If we think of Italy, recent studies have revealed that more than 2,000 km of road tunnels need major maintenance work, with even more than 200 freeway tunnels at risk of collapse, and at least 1,000 km of railway tunnels built between the end of the 1800s and the beginning of the 1900s.

A study by the American Society of Civil Engineers (ASCE) highlighted how the cost of deteriorating infrastructure significantly affects the quality and quantity of jobs in the U.S. economy. In the Report Card 2021 on the conditions of American infrastructure, ASCE estimates that by 2039 each American household is at risk of losing $3,300 a year in disposable income due to infrastructure deficiencies.
