Conservation process model (cpm). A twofold scientific research scope in the information modelling for cultural heritage

The aim of the present research is to develop an instrument able to adequately support the conservation process by means of a twofold approach, based on both BIM environment and ontology formalisation. Although BIM has been successfully experimented within AEC (Architecture Engineering Construction) field, it has showed many drawbacks for architectural heritage. To cope with unicity and more generally complexity of ancient buildings, applications so far developed have shown to poorly adapt BIM to conservation design with unsatisfactory results (Dore, Murphy 2013; Carrara 2014). In order to combine achievements reached within AEC through BIM environment (design control and management) with an appropriate, semantically enriched and flexible The presented model has at its core a knowledge base developed through information ontologies and oriented around the formalization and computability of all the knowledge necessary for the full comprehension of the object of architectural heritage an its conservation. Such a knowledge representation is worked out upon conceptual categories defined above all within architectural criticism and conservation scope. The present paper aims at further extending the scope of conceptual modelling within cultural heritage conservation already formalized by the model. A special focus is directed on decay analysis and surfaces conservation project

Enhancing Heritage fruition through 3D semantic modelling and digital tools: the INCEPTION project

The INCEPTION project, “Inclusive Cultural Heritage in Europe through 3D Semantic Modelling”, started in June 2015 and lasting four years, aims at developing advanced 3D modelling for accessing and understanding European cultural assets. One of the main challenges of the project is to close the gap between effective user experiences of Cultural Heritage via digital tools and representations, and the enrichment of the scientific knowledge. Within this framework, the INCEPTION project goals are consistently aligned while accomplishing the main objectives of accessing, understanding and strengthening European cultural heritage by means of enriched 3D models. At the end of the third year of activity, the project is now facing different challenging actions starting from already developed advancement in 3D data capturing and holistic digital documentation, under interdisciplinary and cross-cutting fields of knowledge. In this direction, the approach and the methodology for semantic organization and data management toward H-BIM modelling will be presented, as well as a preliminary nomenclature for semantic enrichment of heritage 3D models. According to the overall INCEPTION workflow, the H-BIM modelling procedure starts with documenting user needs, including experts and non-experts. The identification of the Cultural Heritage buildings semantic ontology and data structure for information catalogue will allow the integration of semantic attributes with hierarchically and mutually aggregated 3D digital geometric models for management of heritage information

A Web-platform for Linking IFC to External Information during the Entire Lifecycle of a Building

AbstractDuring the lifecycle of a building, much more information is used and produced than can be contained inside a Building Information Model (BIM). The information outside the BIM is seldom connected to the BIM or connected across domains. Furthermore, information in BIM is only accessible to people with sufficient CAD or architectural background, and often expensive software is needed to edit and add data. This inefficient information management causes significant costs in practice. Our research contributes to the development of IFC based web applications in practice and demonstrates a way of linking machine to human readable data thus making the data accessible to non CAD users or architectural experts. In this paper we describe such a platform for the integration of model-based data and non-model based data. We tried to construct a mapping process from IFC properties to a national building element classification system, as a way of structuring the objects and information for use in our web platform. Since both the structure of IFC and most building element classification systems are based on semantic relations of building elements (i.e. holonym, meronym, hypernym), translations by means of a basic reasoning system should be feasible. We elaborate on several uses of this platform in applications for maintenance and reuse of building materials, buildings and built structures

A review of data driven approaches for circular economy in manufacturing

This paper seeks to examine the area of circular economy, providing an overview of the development of data driven circular approaches in manufacturing, particularly Industry 4.0, from the point of view of Reuse, Remanufacturing, Redistribution and Recycle. This paper also aims to develop a working framework for future circular economy research. The Design, methodological approach of this paper focuses on a comprehensive review of literature covering over 51 research papers. These papers are analysed using pie charts and bar charts to understand current trends in circular economy and circular economy related research and future research directions in the field. Findings show that research on circular economy has been steady and gradual with 2014 and 2015 having the most papers on the subject with 43% of the papers from engineering related research. Research which links circular strategies and their application within Industry 4.0 to digital technologies is still a very new area of research and, as such, is an area for further studies. Although papers on Circular Economy and Circular Economy Approaches exists, however, there are no papers that offer an overview of the development of circular approaches within manufacturing. The contribution of this paper is to provide a summary of current trends in circular economy research in manufacturing, within focus on Industry 4.0. A review of this development has been provided in the form of illustrative charts and graphs that identifies these trends. From this a framework for future circular economy research as it relates to manufacturing was developed

Integrated data capturing requirements for 3D semantic modelling of cultural heritage: the inception protocol

The generation of high quality 3D models can be still very time-consuming and expensive, and the outcome of digital reconstructions is frequently provided in formats that are not interoperable, and therefore cannot be easily accessed. This challenge is even more crucial for complex architectures and large heritage sites, which involve a large amount of data to be acquired, managed and enriched by metadata. In this framework, the ongoing EU funded project INCEPTION – Inclusive Cultural Heritage in Europe through 3D semantic modelling proposes a workflow aimed at the achievements of efficient 3D digitization methods, post-processing tools for an enriched semantic modelling, web-based solutions and applications to ensure a wide access to experts and non-experts. In order to face these challenges and to start solving the issue of the large amount of captured data and time-consuming processes in the production of 3D digital models, an Optimized Data Acquisition Protocol (DAP) has been set up. The purpose is to guide the processes of digitization of cultural heritage, respecting needs, requirements and specificities of cultural assets

BIM and Behavioural Simulation for existing buildings re-use design

This paper presents the development of a modelling and simulation approach oriented to the prediction of possible re-use phenomena in the field of existing buildings and built heritage. Its scope is to support the complex balancing of conservation and functional requirements. The approach is based on an Agent-Based Modeling approach that includes entities belonging to the three macro areas - building, use process and users – considered

BIM semantic-enrichment for built heritage representation

In the built heritage context, BIM has shown difficulties in representing and managing the large and complex knowledge related to non-geometrical aspects of the heritage. Within this scope, this paper focuses on a domain-specific semantic-enrichment of BIM methodology, aimed at fulfilling semantic representation requirements of built heritage through Semantic Web technologies. To develop this semantic-enriched BIM approach, this research relies on the integration of a BIM environment with a knowledge base created through information ontologies. The result is knowledge base system - and a prototypal platform - that enhances semantic representation capabilities of BIM application to architectural heritage processes. It solves the issue of knowledge formalization in cultural heritage informative models, favouring a deeper comprehension and interpretation of all the building aspects. Its open structure allows future research to customize, scale and adapt the knowledge base different typologies of artefacts and heritage activities

HBIM development of a brazilian modern architecture icon: glass house by Lina Bo Bardi

Lina Bo Bardi’s Glass House (Casa de Vidro) is a National Historic Landmark designed and built in the late 1940s in São Paulo, Brazil. The house is one of the symbols of modern Brazilian mid-century architecture. It is a historiographical reference of the history of modern architecture in Brazil. This article reports the experience, outcomes, challenges, benefits, and limitations of the Heritage Building Information Modeling (HBIM) process. The HBIM was developed for Lina’s Glass House considering the following steps: modeling planning; data acquisition; model elaboration; recording of pathologies and damage; data management; documentation process. The HBIM developed includes historical information and geometric data from direct measurements, laser scanning, photographic survey, and pathologies documentation. The model allows professionals responsible for architecture, conservation, and restoration to access integrated information on projects and the current condition of the buildings easily and quickly. Good precision was achieved for important building elements, contributing to maintenance and restoration actions. This experience allowed the development of an integrated workflow of activities for collecting, processing, recording, and managing information that may serve as a baseline for future projects for the documentation of modernist buildings231927194
