4. Historical-documentary analysis Historical-documentary analysis stands as a fundamental pillar in assessing the residual safety level of a bridge, serving as a valuable tool to understand its evolution over time. The documentary collection, an integral part of BOLINA Engineering's analytical approach, unfolds through meticulous research in ANAS archives and the acquisition of specific bibliography. This operation not only provides a detailed overview of the design and construction phases but also allows monitoring maintenance interventions over the years. Through historical documentation, it is possible to identify any structural changes, environmental conditions, and applied loads over time, thus providing a comprehensive framework to assess the residual safety level of each bridge. This historical approach
