Sustainable Recovery of Architectural Heritage: The Experience of a Worksite School in San Salvador

This paper presents the experience of both interdisciplinary and sustainable implementation of an educational construction site for the recovery of the architectural heritage in Central America. Rey Prendes House is representative of one hundred and forty-five houses made of wood, stamped steel sheet, and deployé that are located in the historical center of San Salvador. Its origin is linked to historical events, such as the strong migration of foreigners to El Salvador in the late nineteenth and early twentieth century, the presidential decrees that encouraged the reconstruction of the city with anti-seismic materials as a result of the earthquakes of 1873 and 1917. More recently, since 2017, Rey Prendes House has been included in the project funded by the Italian Agency for Development Cooperation. In this paper, the phases of the survey are documented with both materials and degradation analyses, the new design construction with BIM technology for the organization of the educational construction site, the creation of offices and laboratories for restoration and treatments of timber and metal details. Moreover, the study provides a contextual framework with the aim of describing the policies and the projects implemented, highlighting the adopted strategies, the results achieved, and outlining the path followed towards the design solutions for sustainable rehabilitation relating to future use.

VERBUM – virtual enhanced reality for building modelling (virtual technical tour in digital twins for building conservation)

The digital transformation of the construction sector is also involving cultural and architectural heritage conservation management to solve criticalities of information exchange in refurbishment/restoration, from the preliminary steps until the execution and monitoring of interventions. Nevertheless, time and resources required to complete digital models (point clouds, 3D meshes and HBIM model) are extensive and this can cause interruption of knowledge communication among professionals. The VERBuM project (Virtual Enhanced Reality For Building Modelling) aims at investigating how a central Virtual Technical Tour (VTT), would guarantee a continuous stream of information when other disruptive technologies are integrated in the process and their related products are linked to the VTT. The use of a VTT, based on 360° photos, may fill time and resources gaps as it is a rapid up-to-date and high-fidelityto-reality tool. The fostering of the paradigmatic change in refurbishment/restoration process requires the development of all-in-one digital environments for digital twinning of cultural and architectural heritage and its assessment, aware of potentialities and criticalities to be overcame. The research moves from stakeholders’ information requirements to implement the VERBuM process supported by the central VTT, editable via cloud-based platform (VERBuM product) to exchange digital contents, uploaded in different file format, but consulted in VR by all the involved actors via web services, without any software product installation. The tool has been evaluated via SWOT analysis supported by Task-Technology Fit (TTF) model and users’ perceptions. The results provide mitigation measures of threats related to distrust in use of VTT within working groups and fruition of point clouds, meshes and BIM models, possible via WebGL-based libraries.

Dissonance as a concept of preserving the architectural heritage: Case study of the Belgrade Fairground

Belgrade Fairground, built in the 1930s, was the first urban complex designed according to modern principles and the first physical structure built in Belgrade on the left bank of the Sava. During its existence, the complex has undergone radical changes - from a fairground, through a concentration camp during World War II, an art colony in the post-war period, to its current state as a marginalized urban segment inhabited by the homeless, with uncontrolled commercial development . These transformations over time have resulted in the creation of numerous layers of identity, which, from a contemporary point of view, the space itself should testify to. The paper examines the transformations that have taken place in the space, and refers to the mutually opposed events that to some extent have hindered the recovery and development of the former Belgrade Fairground. The paper, in the form of a case study, analyzes the space by exploring the application of dissonance in preserving and revitalizing the architectural heritage, since the concept of dissonance is important for articulating opposing meanings and emphasizing the plurality of values. In order to shed light upon all the characteristic phases of the complex's existence, its morphological transformations and then its functional transformations were analyzed, followed by a presentation of how its social relationship with the Belgrade Fairground has been transformed. Accordingly, the ultimate goal was to find a way to manifest the diversity of the fairground's value and its re-perception as belonging to the urban space.

ARCHITECTURAL HERITAGE IN THE CITY OF ‎NAZNRETH DURING THE OTTOMAN ERA 1517-‎‎1918‎

This study aims to show the urban aspects of the ‎Nazareth during the Ottoman era 1517 – 1918 in the ‎light of the Ottoman documents and the drawings and ‎pictures of European travelers and its role in its ‎transformation from a small village to an urban city and ‎then a district center.

Conservation Challenges and Emerging Trends of Digital Preservation for UNESCO Architectural Heritage, Pakistan

Recent worldwide initiatives at world heritage forums, especially UNESCO, have increased the importance of architectural heritage. Architectural heritage includes built structures that are of outstanding value of natural and cultural identity and require conservation, preservation, presentation and transmission to the future generations. In this regard, UNESCO has enlisted six World Heritage Sites in Pakistan that need to be preserved. Moreover, the heritage sites are undergoing theft, vandalism, natural decay and other socio-cultural harms. One of the state-of-the-art methodologies is the digital preservation of the historic sites. Amongst the various available computer technologies, photogrammetry is the quickest and most cost-effective method that can be used for digital preservation. The research will focus on the digital preservation of UNESCO World Heritage Sites, which is an emerging trend in an architectural context. Developing countries have limited funds and resources and most historic sites are being neglected by the lack of financial resources. The paper suggests digital preservation as an emerging solution, identifies its challenges and suggests photogrammetry as a cost-effective solution to six UNESCO enlisted historic sites of Pakistan. It also suggests that once digitally recorded, information of historic sites can also be used in diverse applications to generate further finances.

Attributing and Defining an Unbuilt 1859 Architectural Plan for the Site of Trogir’s Medieval Walls

This paper discusses the attribution of an anonymous and unbuilt 1859 plan for a four-storey apartment building with commercial spaces on the ground floor, located on the site of the old town walls in Trogir. It proposes Josip Slade as the architect of the plan, interpreting Slade’s architectural language and the development of his approach to architectural heritage. An analysis of the project in a historical socio-political and spatial context, moreover, supports the conclusion that this was intended as rental property, and this paper therefore offers insights into the first known example of the tenement housing building typology in the nineteenth-century Trogir

PRESERVING IDENTITY OF HISTORICAL ENVIRONMENTS IN SIBERIA: A CRITICAL LITERATURE REVIEW

Introduction: Currently, the projects related to the development of identical historical environments in Siberia, Russia, are predominately inconsistent. Yet there is an opportunity to find a more holistic approach to sustaining local heritage, which could address local cultures and identities through an understanding of how the location, as well as specific spatial and architectural practices, evolve. Purpose of the study: The study aimed to establish a theoretical and methodological framework for sustaining the local identity in architectural terms. Methods: According to the methodological recommendations of Groat and Wang, such methods as critical literature review and logical argumentation were used. Results: The research came to the conclusion that the city identity can be unfolded through two or more congruent layers of existence. This study deals with architectural heritage and society as two types of such layers. It suggests that the local identities of historical environments could be sustained by a combination of the following methods: 1) looking to the past, through analyzing the city’s fabric and searching for “social traces” and semiotic meanings; 2) looking to the future, through using participatory design methods. This methodology should be further tested on specific historical environments in Siberia. The critical literature review will provide researchers and practitioners in the field with a fundamental theoretical framework.
