“…The approach must be based on the integration of all the requirements. An optimal retrofit strategy must be considered for the use and reuse of RC buildings and civil engineering works, following well-known multi-criteria schemes [42,43] and resilience concepts [44].…”

In recent years, the preservation strategies of cultural heritage have become an element of considerable importance. Unfortunately, research has often been conducted in an excessively mono-sectoral or disaggregated manner. Moreover, there is a significant number of reinforce concrete (RC) buildings and engineering works that are of historical interest and play a key role during the earthquakes. An urban center, its historical structures and infrastructures or single buildings, if well managed, preserved, protected, recovered and enhanced can represent an excellent source of income and induce a considerable economic development in the neighboring areas. On the other hand, a lack of value appreciation and/or incorrect management represent a significant economic loss in the long-term, but an immediate loss after earthquakes. In this work, the historical and cultural value of these RC structures and infrastructures is discussed and the main critical issues are identified, outlining the fundamental requirements for conservation.

An Innovative Approach for the Enhancement of Public Real Estate Assets

In a context of dwindling resources and growing financial constraints for public administrations, available real estate assets can become an important economic resource both for debt reduction through their alienation, and for carrying out public works through rehabilitation and defunctionalisation using private capital. The latter requires the adoption of innovative policies and strategies to enhance the value of the assets, especially those that are disused or abandoned, which very often represent a critical element in the overall management of public administrations. This study proposes a strategy for the enhancement of public assets using a little-experimented contractual form of public–private partnership. This approach, through a complex exchange transaction, avoids the total disposal of the assets, thus guaranteeing the social and environmental sustainability of the intervention, and also allows for the enhancement of the property with a financially convenient solution for both partners. The balance between the benefits of the two parties is in fact the basis of the model proposed for the final solution.

“…The uninterrupted functioning of such facilities is paramount for the operational continuity of a community or city. However, recent studies have underscored the high seismic risk associated with such constructions [16,17]. Consequently, the call for improving seismic capacity through appropriate modernization interventions has been emphasized.…”

This research, conducted in Zaruma, southern Ecuador, seeks to evaluate the seismic vulnerability and performance level of the Humberto Molina Hospital's reinforced concrete buildings. The study employs an examination of national and international seismic codes for rehabilitation, along with the implementation of recommended techniques. Structural characteristics of the buildings were identified through auscultation, surveys of reinforcing steel, and the extraction of concrete cores. The amassed data, coupled with a seismic hazard analysis of the site, facilitated a structural assessment of the blocks, conducted in accordance with national (MIDUVI) and international (ASCE/SEI) codes. The Federal Emergency Management Agency (FEMA) subsequently proposed rehabilitation alternatives for each block. Due to the importance of the hospital's functions, data collection was limited to blocks B3 and B4. The structural system, composed of moment-resisting concrete frames, exhibits potential vulnerabilities due to knocking (collision) and torsion, attributed to its irregular form. Structural evaluation revealed that block B4 adheres to the drift limits stipulated by the ASCE 41-13 standard (below 2%), while block B3 exceeds these limits (2.05-2.80%). Recommended rehabilitation strategies for B3 encompass mass reduction (removal of the second floor, representing a dead load of 700kg/m 2 and a live load of 200kg/m 2 ), and the introduction of additional rigidity and strength (extension of structural elements). For block B4, it is suggested that each sub-block be made independent. These interventions aim to facilitate the hospital's reopening, thereby benefiting the Zaruma Mining District community.
