Real estate risk: A comprehensive systematic review of the existing academic literature

Locurcio, M., Di Liddo, F., Morano, P., Tatulli, L., Tajani, F. (2026), "Real estate risk: A comprehensive systematic review of the existing academic literature". Real Estate Management and Valuation, https://doi.org/10.2478/remav-2026-0016.

Abstract The rapid and uncontrolled territorial transformation processes that have characterized the global scenario over the past decades have generated a widespread sense of uncertainty and unpredictability, making the implementation of adaptive and flexible territorial management policies increasingly necessary. The need for urban strategies capable of addressing recent environmental, health, and geopolitical emergencies has consequently grown, through governance plans aimed at the efficient management and mitigation of associated risks. In this context, the real estate sector plays a crucial role in the development of resilient and sustainable urban planning programs. In this regard, the development of planning tools based on an accurate assessment of risks and influencing factors has become highly relevant. Specifically, given the complexity of real estate investments, which involve high initial capital and multiple types of risk, rigorous quantitative and objective evaluation models should be adopted and applied. To this end, this study, through a systematic review of the existing academic literature, identifies and analyses the variables considered most decisive for real estate investments. This research, indeed, aims to support the development of integrated approaches for a comprehensive assessment of the financial, socioeconomic, and market factors that contribute to defining the volatility and uncertainty associated with real estate investments.

Abstract With reference to the issue of the evaluation of the purchase prices for leasehold properties, in Italy the transfer of properties built as part of regulated housing initiatives is restricted by a series of constraints, the removal of which entails a set of fees to be borne by the housing lessees. This study, starting from an analysis of similar tools applied in other European territorial contexts, provides a methodological approach for estimating these fees while simultaneously considering the framework established by the current regulations, the trends in the residential market, and the inflation dynamics.

Abstract San Michele Bridge (1889), also known as Paderno d’Adda Bridge, constitutes a true landmark of Italian industrial archaeology and is currently a candidate for insertion in the UNESCO World Heritage List, alongside with a few similar bridges in Europe. After over 136 years since construction, this historic iron viaduct remains in service, still forming a key transportation link in the Lombardia region by supporting both railway and road traffic across the Adda river, one of Italy’s major rivers. Owned by the Italian railway network (RFI), the bridge connects the provinces of Lecco and Bergamo in one of the country’s most industrialized and populated areas. Its strategic importance has ensured ongoing use, prompting an extraordinary maintenance campaign by the owner between 2018 and 2020. These efforts, implemented with care, preserved both structure’s architectural integrity and immersion into a beautiful surrounding landscape. The restoration shall not only has extended the viaduct’s lifespan but also preserved its original functional role. This paper is meant to provide an overview on framework studies delivered in collaboration with the infrastructure owner, aimed at supporting the preservation process of the bridge. Collectively, these efforts shall aim at fostering long-term safety, functionality, and heritage value of San Michele Bridge, reiterating its monumental significance, as an exceptional example of nineteenth-century engineering and architectural ingenuity.

Abstract Numerical time integration still constitutes a rather challenging task when applied to quite stiff structural systems, especially in the presence of complex vibration scenarios. In this context, the accurate evaluation of all displacement, velocity and acceleration dynamic response variables, specifically due to a Moving Load (ML) excitation, poses serious difficulties in possibly reconciling calculated and measured dynamic responses. The present work refers to a novel computational strategy allowing for an “exact” integration within the time-step, and benchmarks its outcomes for the comparison with the numerical integration by known methods. The analysis is exemplified on a continuous beam with multiple spans, including ML transit and subsequent window of free vibration response. The broader underlying framework is that of Structural Health Monitoring (SHM) of a historic railway bridge, which truly challenges the reliability of integration methods in correctly tracing the current dynamic response, in view of system identification and digital twin replication, toward informed management and maintenance scenarios.

Abstract As part of ongoing efforts to study and preserve the San Michele Bridge, a remarkable example of 19th-century iron architecture and a true symbol of Italian industrial archaeology, an experimental campaign was conducted on it in May 2024. Completed in 1889 by the Societa Nazionale delle Officine di Savigliano (SNOS), the San Michele Bridge spans 266 me- ` ters across the Adda River, connecting the towns of Paderno d’Adda (Lecco bank) and Calusco d’Adda (Bergamo bank) in Lombardy, northern Italy. Its innovative design features a doubly built-in parabolic arch and an upper continuous beam, supporting both railway and road traffic. During the experimental campaign, accelerometers were deployed both on the bridge structure and on a crossing railway vehicle, allowing for the simultaneous collection of acceleration data from both systems, aiming at investigating the dynamic behavior of the bridge under vehiclebridge interaction effects, which constitutes a significant excitation mechanism for the bridge structure. This study presents a preliminary dynamic analysis on the bridge that first models the railway vehicle crossings as moving loads through a finite element model of the bridge, enabling numerical simulations of the system’s dynamic response. Then, it foresees a comparison of numerical predictions with experimental data, in order to refine the FEM model and gain insight into the dynamic interaction of the coupled vehicle-bridge system under operating conditions. This research is part of a broader initiative to establish a comprehensive Structural Health Monitoring (SHM) platform for the San Michele Bridge. Such a system would enhance long-term monitoring, facilitate early damage detection, and support the preservation and safety of this historic viaduct. The findings highlight the importance of integrating advanced experimental techniques with numerical modeling to safeguard valuable, historic infrastructure.

Abstract The San Michele Bridge, also known as Paderno d’Adda Bridge, stands as a striking example of 19th-century iron architecture and a prominent symbol of Italian industrialarchaeology heritage. Constructed between 1887 and 1889 by the Societ`a Nazionale delle Officine di Savigliano (SNOS), this impressive infrastructure spans over the Adda River, linking the towns of Paderno d’Adda and Calusco d’Adda, near Milano. Since its inauguration in 1889, the bridge has continuously served as a vital connection between the provinces of Lecco and Bergamo in Lombardy, northern Italy. Following nearly 136 years of service, the bridge underwent extraordinary restoration works from 2018 to 2020, ensuring up to now its continued functionality for both railway and road traffic. After that, from May 7 to 10, 2024, a dedicated experimental campaign was conducted on the bridge to investigate its current structural response under various dynamic excitations, including ambient vibrations with no traffic, dynamic response with vehicular transit and controlled train passages. During such a campaign, diverse acceleration data were collected and then analyzed with the aim of extracting the salient modal properties of the bridge. A comparison of the processed data with available records prior to bridge restoration revealed a rather good correspondence with the identified modal properties, within a time span of about 14 years. This seems to suggest that the recent restoration works may have displayed a minimal impact on the global dynamic behavior of the structure, in terms of modal features. The findings from this study shall provide valuable insights for future research developments and contribute to the ongoing deployment of a Structural Health Monitoring (SHM) platform for the San Michele Bridge, contributing to the long-term goal of monitoring and preserving this historic viaduct.
