The public library “Bertoliana” in Vicenza is the oldest and most important library in the city. In the historic homes of buildings “Palazzo San Giacomo” and “Palazzo Costantini” a structural monitoring system using displacement transducers in the most significant cracks was installed and is still active. Also in 2010 both a comprehensive set of experimental investigations (flat jack tests, coring tests on masonry, tests with covermeter) and the seismic verification of the central building complex were carried out.
