“…The most difficult places to carry out condition assessments are the steel connections of prefabricated elements. As described in [ 35 ], in order to reduce nuisance to residents, it is recommended that joints should be tested in stairwell areas. By assessing the condition of several such connections, including the conformity of their workmanship with catalogue solutions, it is possible to determine with what care the connections were made and whether degradation processes (e.g., in the form of corrosion) are occurring.…”

“…This article is a continuation of the analyses related to the improvement of testing methodology for large-panel structures and the implementation of modern non-destructive testing methods in engineering practice. The authors described their earlier analyses in detail [ 35 , 36 , 37 , 38 , 39 ], wherein they presented a wide range of tests using different methods. The research results presented in this article are novel and have not been taken from other sources.…”

Structural condition diagnostics provides the basis for decision making regarding the possibility of continued safe operation, necessary reinforcement, repair work, and in extreme cases, dismantling of the structure. The most reliable results concerning the condition and strength of materials are provided by destructive testing. However, these tests are very time-consuming, costly, and difficult to perform on in-service facilities. In addition, they involve the need to obtain the consent of the occupants of the premises and subsequent renovations. This article focuses on presenting an opportunity to reduce the number of destructive tests necessary to reliably assess the condition of large-panel structures, which constitute a significant housing stock in Europe. Based on tests carried out on a real building, the risk factors associated with obtaining reliable results by non-destructive methods were determined. Areas where destructive testing is necessary were identified. In addition, reference was made to standard recommendations and guidelines from a reputable research institution. Practical guidelines were formulated regarding the diagnostics of large-panel structures, resulting in a reduction in the number of destructive tests required.

“…In the last decade, this modernist architecture has become an attractive topic for the younger generation [22] which especially increases activities around rethinking and revitalizing the modernist heritage and has become a global trend [25]. This is because many buildings have undergone advanced degradation processes over the decades, making repair or modernization work necessary [35]. Considering the fact that most of these buildings are almost 60 years old and still in use, the implementation of restrictive regulations and technical conditions, e.g., those with regard to energy standards and thermal comfort are also a part of the triggering process for the renovation.…”

“…One such building is the Tomis department store in Constanta, Romania (1973), where the main structure was preserved but new facades and superstructures were built [34]. Another building is the Banca Nat , ională a Moldovei (1974) in Moldova, which radically changed the design of the building, both in the height of the building and in the general style [35]. Recently, the building of the "Enver Hoxha" Museum in Tirana, Albania (1988) was also transformed into a shopping center [38].…”

Socialist modernist architecture in the Balkan has left a valuable legacy of remarkable buildings from this century, which brought a mixture of new experiences and local traditions. Unfortunately, after the 1990s, many of these buildings have been neglected, improperly treated, or abandoned. This paper focuses on the iconic socialist modernist office building “Rilindja” in Prishtina, Kosovo, which was built in 1979. In 2010, the building envelope was changed in the name of revitalization, without considering the energy aspect. The study aims to present energy performance analysis through cost-optimal renovation measures of the building envelope while restoring the architectural values before the last renovation. Using Archicad and EcoDesigner STAR, a BIM model was created, and energy analysis was conducted. The findings indicate that eighteen proposed energy efficiency measures can achieve a reduction in energy consumption for heating and cooling of more than 80% over the life cycle period of 20 years. The comparison before and after renovation considering restoring and preserving the inherent values, while integrating energy efficiency measures was necessary, as there is a lack of such studies in the general literature. Finally, the potential of restoring the collective memory through cost-optimal analysis is emphasized as an approach for similar cases.

“…Examples of tests on large-panel structures using a range of destructive and non-destructive methods were presented in [9]. In the case of large-panel structures, the most sensitive structural locations are the joints of prefabricated elements, the description of tests and examples of analysis of which were presented in [10]. A large number of defects also relate to facades, the studies of which have been presented in [11,12].…”

Technological developments involving the implementation of modern measuring equipment and the digitalisation of civil engineering can contribute to extending the service life of buildings. Large-panel buildings constitute a large housing stock throughout Europe. This paper presents the possibility of using laser scanning to identify typical assembly defects in large-panel buildings. Based on point cloud data, numerical models were created to assess the impact of improper assembly on the elements’ performance. It was indicated that using scanning to identify and monitor the displacement of structural elements does not relieve experts of the need to perform other tests. Analyses related to the possibility of using Building Information Modeling technology to manage large-panel buildings were also conducted. A parametric model was made, from which a number of possibilities of its use at every stage of the building’s life were presented in an example. It was highlighted that parametric models of large-panel buildings, due to their repeatable geometry, can be copied for use in managing entire neighbourhoods. Limitations associated with implementing BIM technology in practice were also formulated. The analyses and research performed confirm the validity of implementing modern research methods in engineering practice and digitising the documentation of large-panel buildings.
