Academic literature on the topic 'Heritage Building Information Modeling'

Studies revealed that most heritage buildings in Malaysia are deteriorating due to poor maintenance of recorded documentation. Unfortunately, conserving heritage buildings is a complex and multi-layered process that requires collaboration between different stakeholders. Heritage Building Information Modeling (HBIM) is seen as an opportunity to establish a well-managed data collection. This paper attempts to examine the awareness, benefits and challenges of the implementation of BIM among stakeholders. Sixty-nine respondents with BIM knowledge and skills answered the questionnaire. Findings show significant attributes that could improve building conservation project performance, delivery and management, hence several challenges that need further improvement.

Over the past four decades, building modeling has taken numerous forms utilizing available technologies and software. Building information modeling (BIM) has significantly developed with the continuous advancements in the information technology and hardware industries. The evolution of BIM has attracted many researchers to explore its possible applications in modeling buildings and facilities with a humanitarian heritage value. However, researches have not been limited to that, as they later expanded to test the applicability of BIM in progressing the fields of maintenance and rehabilitation, operation and management, and even checking the durability of such buildings against varying circumstances and usability as well. As a result of a deep literature review, this research is developed to provide a critique of the previous studies conducted on the fields of heritage building information modeling (HBIM), the relevant software and equipment used in those studies, as well as case studies and applications used to demonstrate HBIM capabilities. Also, two case studies of Qasr Al Farid and Al-Bugiry buildings in KSA were implemented in this research to demonstrate the capabilities of HBIM in preserving the heritage value of historic buildings and monuments and to provide possible means of archiving the heritage value of those buildings utilizing state-of-the-art technologies. This study is expected to aid governments and decision makers of heritage buildings in understanding the positive impacts of including the HBIM in their management and operational processes, and will also act as a beneficial guiding tool for academic researchers to identify the gaps and limitations in previous studies to work towards overcoming them.

AbstractThe paper discusses the possibilities of HBIM usage in foreign countries and Lithuania. Methods used in the paper are analysis of the literary sources, review of legal documents relating to the digitization of buildings, and analysis of case studies in foreign countries. The aim of the paper is to present the main stages of HBIM process for the historical buildings renovation. Nowadays HBIM process in Lithuania focuses on scanning heritage sites and reproducing realistic images and the attribute data for cultural heritage sites and incorporating them into HBIM models. The process is in the initial stage.

BIM (Building Information Modeling) processes are the most effective way to know existing architectural structures, integrating the most advanced potentials of 3D modeling and the structured storage of heterogeneous information. Many HBIM (Heritage Building Information Modeling) applications lead to the systematization of survey data, even though a univocal working method is not yet clearly defined. This research considers the decomposition of architecture, based on structured criteria, and its reconstruction, through ideal models, as the main moments of the HBIM process. This hypothesis is verified through a procedure that links the survey 3D data with the characteristics of the ideal HBIM model, which allows a continuous comparison between the project model and as-built. The research provides for the setting up of a general methodology that, according to a growing approach to the complexity of the analyzed buildings, compares the process followed on two architectural structures. The study analyzes some important HBIM issues: The relationship between the semantic modeling and the surfaces’ continuity of architectural heritage; the relationship between the elements standardization, geometric irregularities, and material heterogeneity; the reliability of the built models; and the evaluation of the gap between an ideal model and the objective accuracy of surveying.

This paper proposes CulTO, a software tool relying on a computational ontology for Cultural Heritage domain modelling, with a specific focus on religious historical buildings, for supporting cultural heritage experts in their investigations. It is specifically thought to support annotation, automatic indexing, classification and curation of photographic data and text documents of historical buildings. CULTO also serves as a useful tool for Historical Building Information Modeling (H-BIM) by enabling semantic 3D data modeling and further enrichment with non-geometrical information of historical buildings through the inclusion of new concepts about historical documents, images, decay or deformation evidence as well as decorative elements into BIM platforms. CulTO is the result of a joint research effort between the Laboratory of Surveying and Architectural Photogrammetry “Luigi Andreozzi” and the PeRCeiVe Lab (Pattern Recognition and Computer Vision Lab) of the University of Catania,

Certain historical works of civil engineering should be preserved as heritage monuments and when possible should continue serving the function they were designed for. Old stone bridges could be sustainably maintained but their conservation requires accurate documentation. In this study, we have scanned Ízbor bridge (1860) in Spain, and to facilitate conservation, we have modeled the ancient bridge using BIM (building information modeling). We propose a method and a model for this kind of bridge to be used as a reference for similar heritage monuments. Ízbor bridge modeled in this way will be useful for government planning and conservation agencies.

We discuss the evolution and state-of-the-art of the use of Building Information Modelling (BIM) in the field of culture heritage documentation. BIM is a hot theme involving different characteristics including principles, technology, even privacy rights for the cultural heritage objects. Modern documentation needs identified the potential of BIM in the recent years. Many architects, archaeologists, conservationists, engineers regard BIM as a disruptive force, changing the way professionals can document and manage a cultural heritage structure. The latest years, there are many developments in the BIM field while the developed technology and methods challenged the cultural heritage community in the documentation framework. In this review article, following a brief historic background for the BIM, we review the recent developments focusing in the cultural heritage documentation perspective.

El flujo de trabajo en los proyectos patrimoniales presenta problemas relacionados con la desorganización de procesos, la dispersión de información y el uso de herramientas obsoletas. Diferentes organizaciones abogan por usar métodos innovadores para tratar de resolver estos problemas. BIM (Building Information Modelling) se ha postulado como una metodología adecuada para mejorar la gestión del patrimonio arquitectónico. La aplicación de BIM a construcciones históricas, denominada HBIM (Heritage BIM), ha probado tener múltiples ventajas para gestionar proyectos patrimoniales. Sin embargo, la literatura científica pone de manifiesto la necesidad de seguir investigando en los procesos de los proyectos patrimoniales, la implementación práctica de HBIM, la simplificación de la laboriosa tarea de modelado HBIM y la documentación de los proyectos HBIM. La finalidad de esta investigación es el desarrollo de un protocolo que ordene la gestión de proyectos patrimoniales usando HBIM y el diseño de una plataforma web que sincronice la información patrimonial. DSR (Design Science Research) es el método de investigación usado para desarrollar dicho protocolo que ayude a mejorar el flujo de trabajo en los proyectos patrimoniales. Las técnicas de investigación usadas han sido el análisis documental, casos de estudio, entrevistas semiestructuradas y grupos focales. Se analizaron los procesos HBIM y se estudiaron los requerimientos de los agentes patrimoniales. Como resultado, se desarrolló el protocolo BIMlegacy, dividido en ocho pasos y contemplando a todos los agentes que participan en proyectos patrimoniales. Dicho protocolo se aplicó en el caso de estudio de Fixby Hall, en Huddersfield (Reino Unido), y sus resultados fueron expuestos en un workshop interdisciplinar para validar y mejorar el protocolo BIMlegacy. Basado en este protocolo, se desarrolló la plataforma BIMlegacy como herramienta para poder llevar a cabo este flujo de trabajo donde agentes interdisciplinares pueden unificar y sincronizar la información patrimonial. Este innovador sistema en la nube conecta la base de datos intrínseca de los programas HBIM con bases de datos patrimoniales usando un plug in para Revit de Autodesk, una web API, un servidor SQL y un portal web. La plataforma BIMlegacy se diseñó como una web de trabajo, pero también como una web de difusión cultural donde el público generalista puede acceder a cierta información de los monumentos. El protocolo y la plataforma BIMlegacy fueron usados para gestionar el proyecto de Registro de San Juan del Hospital. El protocolo, la plataforma y los resultados del proyecto de San Juan del Hospital fueron expuestos en un grupo focal en Valencia con profesionales para su evaluación científica. La contribución teórica de esta investigación ha sido el descubrimiento de problemas en el modelado HBIM que no habían sido especificados antes, beneficios del HBIM (por ejemplo, el uso de plataformas online o el filtrado de información en sistemas HBIM) y requerimientos para implementar HBIM en la práctica tales como la necesidad de un protocolo simple e intuitivo y de ofrecer entrenamiento específico a los agentes no técnicos. Las contribuciones prácticas al conocimiento han sido la creación del protocolo BIMlegacy con la lista de agentes patrimoniales y la integración de procesos tradicionales, el diseño de la plataforma BIMlegacy con la sincronización de la información en tiempo real que permite que los agentes no técnicos puedan participar activamente en los modelos HBIM, el uso de HBIM como una herramienta de gestión, y la aportación de información rigurosa volcada por profe

Les tècniques d'investigació utilitzades han estat l'anàlisi documental, entrevistes semi-estructurades i grups focals. També es van analitzar els processos HBIM i es van estudiar els requeriments dels agents patrimonials. HBIM es va proposar com el model virtual que acull la informació patrimonial i que articula els processos. Com a resultat, es va desenvolupar el protocol BIMlegacy, dividit en vuit fases, contemplant a tots els agents que participen en projectes patrimonials. Aquest protocol es va aplicar en el cas d'estudi real de Fixby Hall, a Huddersfield (Regne Unit), i els seus resultats van ser exposats en un workshop interdisciplinari per validar i millorar el protocol.

[EN] Heritage architectural projects involve collaborative work between different stakeholders, e.g. architects, engineers, archaeologists, historians, restorers, managers, etc. Traditionally, each discipline works independently, generating dispersed data. The workflow in historic architecture projects presents problems related to the lack of clarity of processes, dispersion of information, and the use of outdated tools. Different heritage organisations have showed interest in innovative methods to resolve those problems. Building Information Modelling (BIM) has emerged as a suitable computerised system to improve the management of heritage projects. BIM application to historic buildings, named Heritage Building Information Modelling (HBIM), has shown benefits in managing heritage projects. The HBIM literature highlights the need for further research in terms of the overall processes of heritage projects, its practical implementation, the need of simplifying the laborious modelling task, and need for better standards of cultural documentation. This investigation aims to develop a protocol for heritage project processes using HBIM and an online work platform prototype where interdisciplinary stakeholders can unify and synchronise heritage information. Design Science Research (DSR) is adopted to develop this protocol. Research techniques used include documentary analysis, case studies, semi-structured interviews, participative workshop, and focus groups. An analysis of HBIM processes and a study of heritage stakeholders' requirements were performed through documentary analysis and semi structured interviews with stakeholders involved with relevant monuments. HBIM is proposed as the virtual model which will hold heritage data and will articulate processes. As a result, a simple and visual HBIM protocol, BIMlegacy, was developed. It is divided in eight steps and it contemplates all the stakeholders involved. BIMlegacy was applied in the Fixby Hall case study and its results were evaluated in a workshop with interdisciplinary stakeholders. An online work platform prototype, also named BIMlegacy, was developed, where interdisciplinary stakeholders can unify and synchronise heritage information. This innovative in-cloud system connects the intrinsic HBIM software database with heritage documentary databases using a Revit Autodesk Plug-in, a web Application Program Interface, a Structured Query Language server, and a web portal. BIMlegacy is an online platform to facilitate working but also a cultural diffusion web where general visitors can access to the information of the monuments. The BIMlegacy protocol and platform were implemented in two case studies Fixby Hall in Huddersfield (United Kingdom) and San Juan del Hospital in Valencia (Spain). BIMlegacy and the results of San Juan project were revealed in a workshop and in a focus group with external professionals for its evaluation. This research contributes within the theoretical knowledge highlighting modelling issues that were unknown before, benefits of using HBIM (a.e. the use of online platforms, filtering the information in HBIM database systems, the integration of cultural divulgation with HBIM) and needs in terms of implementing HBIM in practice such as the importance to have a simple and intuitive protocol to be useful and that the non-designer stakeholders require specific HBIM training. The practical contributions are the creation of the BIMlegacy protocol with the list of stakeholders and processes, the design of the BIMlegacy platform with the synchronisation of information in real time allowing the non-technical stakeholders to actively participate in HBIM models, the use of HBIM as management system, and the benefit for society and local communities since the rigorous information uploaded by professionals will be accessible to the public.

Since the UNESCO constitution was established in 1945, and since the global convention for the protection of the World’s Cultural and Natural Heritage in 1972, a variety of challenges and issues have emerged in relation to providing UNESCO world heritage nomination files (WHNF). The UNESCO World Heritage have published a resource manual to help with the preparation of the nomination files. This manual is intended to provide basic principles and guidance to assist state parties as they begin the working process. However, the resource manual states that, “there are many different ways to prepare a nomination file” and there is no recommended method defined. This could provide validity to the task of improving and creating other methods to aid with preparing the nomination file. In the last decade, a number of traditional surveying methods have been used for several heritage sites in the world in order to provide the nomination files. However, these methods have proved unreliable as they have always missed out critical and comprehensive details, as well as taking a long time to process. As such, these issues can affect the UNESCO world heritage nomination and the world heritage community decisions. The concept of using terrestrial laser scanning and Photogrammetry has been utilised in many heritage sites around the world. Besides, the integration of the laser scanning output data and the Building Information Modelling (BIM) has also been introduced as a new method for documenting and managing these heritage sites and is known as Heritage BIM (HBIM). This research will focus on developing an interactive approach to the documentation, sharing, digitising, and management of the heritage buildings. This will be through collecting data from various sources, including geometrical, dimensional, historical, thematic, and constructive information, to be used as a new model for meeting the requirements of UNESCO’s WHNF. The HBIM method has been adopted for a case study of Historic Jeddah, which is described as Jeddah Heritage BIM (JHBIM) that focuses on Nasif Historical House, which is considered to be one of the most important historical houses in Jeddah, Saudi Arabia. The main reason for choosing this case study is due to the huge gap in the research in relation to heritage buildings, with almost no official architectural database or accurate records existing with regard to the buildings in Historic Jeddah.

La maquette numérique de bâtiments historiques (Heritage-BIM) est devenue un enjeu majeur dans la modélisation. Le modèle HBIM ainsi obtenu comprend une description paramétrique et sémantique des éléments constitutifs du patrimoine. La thèse présente des méthodes de constructions HBIM à partir de la documentation historique, de nuages de points, de maillage de surfaces et de géométrie solide. Un concept de mesh-to-HBIM est proposé à l'aide de la programmation visuelle, qui permet de transformer les « familles » paramétriques et les structures géométriques en modèles paramétriques et sémantiques HBIM. La modélisation paramétrique HBIM consiste à créer manuellement des Familles Revit paramétriques et une reconstruction de bâtiment semi-automatisée par l'application de scripts Dynamo. Le processus de modélisation sémantique HBIM transforme directement des géométries segmentées de maillages ou de solides vers l'environnement BIM. Les éléments segmentés et individualisés peuvent être stockés et gérés dans cet environnement avec des compléments d'informations d'association entre éléments
Heritage Building Information Modelling (HBIM) is a major issue in heritage documentation and conservation. The obtained HBIM model provides a parametric and semantic description of the heritage elements. This thesis presents methods for the generation of HBIM models from point clouds (obtained by photogrammetry or laser scanning), surface mesh and solid geometry. A concept of solid/mesh-to-HBIM is proposed using Autodesk Dynamo visual programming, which transfers the parametric “Family” and geometric structures to parametric and semantic HBIM models. The parametric HBIM modelling process involves conventional manual parametric “Family” creation and semi-automated building reconstruction by Dynamo. The semantic HBIM modelling process directly transfers the segmented solid geometry and closed mesh-to-BIM environment. The segmented elements can be stored and managed in the BIM environment with attached attributes information and relationships established among the elements

In the case of Cultural Heritage buildings, the need for an effective, exhaustive, efficient method to replicate its state of being in an interactive, three-dimensional environment is today, of paramount importance, both from an engineering as well as a historical point of view. Modern geomatics entails the usage of Terrestrial Laser Scanners (TLS) and photogrammetric modelling from Structure-from-Motion (SfM) techniques to initiate this modelling operation. To realize its eventual existence, the novel Historic Building Information Modelling (HBIM) technique is implemented. A prototype library of parametric objects, based on historic architectural data, HBIM allows the generation of an all-encompassing, three-dimensional model which possesses an extensive array of information pertaining to the structure at hand. This information, be it geometric, architectural, or even structural, can then be used to realize reinforcement requirements, rehabilitation needs, stage of depreciation, method of initial construction, material makeup, historic alterations, etc. In this paper, the study of the San Michele in Acerboli’s church, located in Santarcangelo di Romagna, Italy, is considered. A HBIM model is prepared and its accuracy analyzed. The final model serves as an information repository for the aforementioned Church, able to geometrically define its finest characteristics.

Il complesso monumentale storico denominato Fabbrica Vecchia a Marina di Ravenna è un soggetto ideale per testare l’applicazione concreta delle metodologie e degli strumenti informatici attualmente riconducibili ai sistemi complessivamente ascritti al termine BIM. Al fine di creare la base dei dati necessaria, sono state verificate le modalità operative e le potenzialità di tecnologie geomatiche basate su campionamento statistico (quali Laser Scanner e approccio fotogrammetrico Structure From Motion) in raffronto a sistemi analogici a misure dirette selettive. La tesi mira nel suo complesso a verificare la reale applicabilità di soluzioni HBIM (Heritage Building Information Modeling) in un caso di studio concreto particolarmente articolato, non solo dal punto di vista geometrico, e valutare la produttività di tali tecniche e tecnologie rispetto all’approccio tradizionale.

O Building Information Modeling (BIM) é considerado como o mais recente paradigma a adotar no exercício da Arquitetura, Engenharias e Construção (AEC) e Design. Um método de trabalho destacado como a aptidão a ter no futuro do setor mundial, onde todas as suas fases e dimensões validam o espírito de colaboração, partilha de informação, interajuda e otimização. Sendo já aplicado em diversos países como cariz obrigatório na profissão, desde 2016 como os Estados Unidos, Reino Unido e Singapura, a visão mundial a cerca desta ferramenta no ensino é ainda bastante elementar comparativamente com as suas imensas potencialidades, principalmente em Portugal. Ciente de que um profissional adquire conhecimentos e competências fulcrais à profissão numa fase anterior a este estatuto é de interesse geral que as habilitações que se adquirem com a metodologia BIM sejam ensinadas no curso de Arquitetura. Porém tal importância não se verifica, tendo como resultado um curso desajustado das novas necessidades da profissão. Perante o problema apresentado surgiu a motivação para o desenvolvimento de uma dissertação que apostasse numa proposta de um modelo curricular para o curso de Mestrado Integrado em Arquitetura que incorpore o Building Information Modeling.
ABSTRACT: The Building Information Modeling (BIM) it’s considered as the latest paradigm to be adopted in the exercise of Architecture, Engeneering, and Construction (AEC) and Design. A working method model highlighted as the ability to have in the future of the global sector, where all of its fases and dimensions validate the spirit of colaboration, sharing of information, mutual aid and optimization. Having already been aplied in several countries as required in the profession, since 2016 like the United States, United Kingdom and Singapore, the world vision about this tool in education it’s rader elementary compared to its immense potentialities, mainly in Portugal. Aware that a professional acquires knowledge and core competencies at a stage prior to this status is of general interest that the qualifications that are acquired with the BIM methodology are taught in the Architecture course. But such importance is not verified, resulting in a misfiting course face of the new needs of the profession. Faced with the presented problem, the motivation rised for the development of a dissertation that focused on a proposal of a curricular model for the Mestrado Integrado em Arquitetura course that incorporate Building Information Modeling.

"Nowadays, many companies in the Architecture/Engineering/Construction (AEC) industry are using Building Information Modeling (BIM) in achieving a faster, sustainable and more economic project. Among the new developed concepts and BIM applications, two of the concepts most frequently used with the support of BIM technology in the planning, organization and scheduling of projects are 4D and 5D in which a 3D model is tied to its time execution (4D) at any point in time and its corresponding cost (5D). However, most of these applications concentrate on modeling the building but it does not include a corresponding modeling of the site in which the building is located. To date, there are few studies and systematic implementation of the site and the building integrated into one BIM model. This site-building integrated model can also be conceptualized as ¡°6D BIM¡± model. The benefit of integrating the site and building together into one model is that the building is no longer treated in isolation of its surround site but incorporates extremely helpful short-term and long-term information for the owner, designer, and builder regarding site topography, landscaping, access roads, ground conditions and the location of site utilities. Major existing research and technology issues that are preventing this site-building integration deal with functionality and interoperability of the BIM software, different orientation and coordination of building model and site model. The objectives of this thesis are to explore current organizational and technological issues preventing this integration, to investigate a feasible method to create a site-linked BIM model, and to discuss the benefits and limitations of bringing BIM concept to the site conditions. The research has been conducted by an extensive review on the literature related to the topic of interest published primarily by AEC. A review on current applications of Geographic Information Systems (GIS) has also been included because of the wider context provided by this technology to the specific topic of this research. Related BIM software developed by three different vendors ¡ªhas been discussed and compared to determine the level of feasibility and operational features of technological support necessary to implement the site-linked BIM model. A case study based on the design and construction of the WPI Recreational & Sports Center, currently under construction, was developed to explore and understand the details that are involved in creating a new site model and to link it with the existing 3D building model. What has been learned from the analysis of this case study is presented, discussed and analyzed in terms of benefits and limitations. Recommendations for future extensions from both the research aspect and the technology support aspect finally presented. These include the creation of 3D BIM Campus Map, which is one site model with several building models placed on it to facilitate future planning of new building and/or maintenance and operation of the current buildings and campus infrastructure.   "

Dalla raffigurazione artistica fino alla modellazione digitale, passando per il disegno tecnico, la rappresentazione del progetto d’architettura ha conosciuto nel tempo evoluzioni significative che solo di recente hanno raggiunto l’apice nell’utilizzo di modelli cognitivi in grado di collezionare ed organizzare il patrimonio di informazioni che gravitano attorno all’intero processo edilizio. L’impiego sempre più diffuso dello strumento informatico, insieme al coordinamento delle specializzazioni nelle molte discipline coinvolte nel progetto, ha favorito negli ultimi anni l’adozione del Building Information Modeling un processo che permette di rivoluzionare il mondo delle costruzioni, coprendo molteplici aspetti del ciclo di vita per un manufatto edilizio. Questa Tesi intende presentare in maniera specifica le tappe che hanno consentito il formarsi del BIM. La migliore capacità di gestione, un linguaggio comune tra i progettisti, un’ottimizzazione di risorse e costi, unito ad un controllo convincente ed accurato delle fasi di lavoro, sono alcune delle potenzialità non ancora completamente espresse dal Building Information Modeling che è destinato a divenire una consapevolezza strategica nel bagaglio culturale del professionista contemporaneo.

Tese de Doutoramento em Arquitetura, com a especialização em Conservação e Restauro apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutor.
As metodologias associadas ao software BIM (Building Information Modeling) representam nos dias de hoje um dos sistemas integrados mais utilizado para a construção de novos edifícios. Ao usar BIM no desenvolvimento de projetos, a colaboração entre os diferentes intervenientes num projeto de arquitetura, engenharia e construção, melhora de um modo muito significativo. Esta tecnologia também pode ser aplicada para intervenções em edifícios existentes. Na presente tese pretende-se melhorar os processos de registo, documentação e gestão da informação, recorrendo a ferramentas BIM para estabelecer um conjunto de diretrizes de fluxo de trabalho, para modelar de forma eficiente as estruturas existentes a partir de nuvens de pontos, complementados com outros métodos apropriados. Há vários desafios que impedem a adoção do software BIM para o planeamento de intervenções em edifícios existentes. Volk et al. (2014) indica que os principais obstáculos de adoção BIM são o esforço de modelação/conversão dos elementos do edifício captados em objetos BIM, a dificuldade em actualizar informação em BIM e as dificuldades em lidar com as incertezas associadas a dados, objetos e relações que ocorrem em edifícios existentes. A partir desta análise, foram desenvolvidas algumas diretrizes de fluxo de trabalho BIM para modelação de edifícios existentes. As propostas indicadas para as diretrizes BIM em edifícios existentes, incluem tolerâncias e standards para modelar elementos de edifícios existentes. Tal metodologia permite que as partes interessadas tenham um entendimento e um acordo sobre o que é suposto ser modelado. Na presente tese, foi investigado um conjunto de tópicos de pesquisa que foram formuladas e colocadas, enquadrando os diferentes obstáculos e direcionando o foco de pesquisa segundo quatro vectores fundamentais: 1. Os diferentes tipos de dados de um edifício que podem ser adquiridos a partir de nuvens de pontos; 2. Os diferentes tipos de análise de edifícios; 3. A utilização de standards e BIM para edifícios existentes; 4. Fluxos de trabalho BIM para edifícios existentes e diretrizes para ateliers de arquitectura. A partir da pesquisa efetuada, pode-se concluir que é há necessidade de uma melhor utilização da informação na tomada de decisão no âmbito de um projeto de intervenção arquitetónica. Diferentes tipos de dados, não apenas geométricos, são necessários como base para a análise dos edifícios. Os dados não geométricos podem referir-se a características físicas do tecido construído, tais como materiais, aparência e condição. Além disso, o desempenho ambiental, estrutural e mecânico de um edifício, bem como valores culturais, históricos e arquitetónicos, essenciais para a compreensão do seu estado atual. Estas informações são fundamentais para uma análise mais profunda que permita a compreensão das ações de intervenção que são necessárias no edifício. Através de tecnologias Fotogrametria (ADP) e Laser Scanning (TLS), pode ser gerada informação precisa e actual. O produto final da ADP e TLS são nuvens de pontos, que podem ser usadas de forma complementar. A combinação destas técnicas com o levantamento tradicional Robotic Total Station (RTS) fornece uma base de dados exata que, juntamente com outras informações existentes, permitem o planeamento adequado da intervenção. Os problemas de utilização de BIM para intervenção em edifícios existentes referem-se principalmente à análise e criação de geometria do edifício, o que geralmente é uma etapa prévia para a conexão de informação não-geométrica de edifícios. Por esta razão, a presente tese centra-se principalmente na busca de diretrizes para diminuir a dificuldade em criar os elementos necessários para o BIMs. Para tratar dados incertos e pouco claros ou informações semânticas não visíveis, pode-se complementar os dados originais com informação adicional. Os fluxos de trabalho apresentados na presente tese focam-se principalmente na falta de informação visível. No caso de projetos de remodelação, a informação não visível pode ser adquirida de forma limitada através de levantamentos ADP ou TLS após a demolição de alguns elementos e/ou camadas de parede. Tal metodologia permite um melhor entendimento das camadas de materiais não visíveis dos elementos do edifício, quando a intervenção é uma demolição parcial. Este processo é útil apenas se uma parte do material do elemento é removida e não pode ser aplicada a elementos não intervencionados. O tratamento da informação em falta pode ser feito através da integração de diferentes tipos de dados com diferentes origens. Devem ser implementados os fluxos de trabalho para a integração da informação. Diferentes fluxos de trabalho podem criar informação em falta, usada como complemento ou como base para a tomada de decisão quando não há dados disponíveis. Relativamente à adição de dados em falta através da geração de nuvem de pontos, os casos de estudo destacam a importância de planear o levantamento, fazendo com que todas as partes compreendam as necessidades associadas ao projeto. Além da precisão, o nível de tolerância de interpretação e modelação, requeridos pelo projeto, também devem ser acordados e entendidos. Nem todas as ferramentas e métodos de pesquisa são adequados para todos os edifícios. A escala, os materiais e a acessibilidade do edifício desempenham um papel importante no planeamento do levantamento. Para lidar com o elevado esforço de modelação, é necessário entender os fluxos de trabalho necessários para analisar a geometria dos elementos do edifício. Os BIMs construídos são normalmente gerados manualmente através de desenhos CAD e/ou nuvens de pontos. Estes são usados como base geométrica a partir da qual a informação é extraída. A informação utilizada para planear a intervenção do edifício deve ser verificada, confirmando se é uma representação do estado actual do edifício. As técnicas de levantamento 3D para capturar a condição atual do edifício devem ser integradas no fluxo de trabalho BIM, construído para capturar os dados do edifício sobre os quais serão feitas as decisões de intervenção. O resultado destas técnicas deve ser integrado com diferentes tipos de dados para fornecer uma base mais precisa e completa. O atelier de arquitetura deve estar habilitado com competências técnicas adequadas para saber o que pedir e o que utilizar da forma mais adequada. Os requisitos de modelação devem concentrar-se principalmente no conteúdo deste processo, ou seja, o que modelar, como desenvolver os elementos no modelo, quais as informações que o modelo deve conter e como deve ocorrer a troca de informações no modelo. O levantamento das nuvens de pontos deve ser efectuado após ter sido estipulado o objetivo do projeto, standards, tolerâncias e tipo de conteúdo na modelação. As tolerâncias e normas de modelação são diferentes entre empresas e países. Independentemente destas diferenças, os documentos standard têm como objetivo produzir e receber informação num formato de dados consistente e em fluxos de trabalho de troca eficiente entre os diferentes intervenientes do projeto. O pensamento crítico do fluxo de trabalho de modelação e a comunicação e acordo entre todas os intervenientes são os principais objetivos das diretrizes apresentadas nesta tese. O estabelecimento e o acordo de tolerâncias de modelação e o nível de desenvolvimento e detalhes presentes nas BIMs, entre as diferentes partes envolvidas no projeto, são mais importantes do que as definições existentes atualmente e que são utilizadas pela indústria da AEC. As ferramentas automáticas ou semi-automáticas para extração da forma geométrica, eliminação ou redução de tarefas repetitivas durante o desenvolvimento de BIMs e a análise de condições de ambiente ou de cenários, são também um processo de diminuição do esforço de modelação. Uma das razões que justifica a necessidade de standards é a estrutura e a melhoria da colaboração, não só para os intervenientes fora da empresa, mas também dentro dos ateliers de arquitetura. Os dados e standards de fluxo de trabalho são difíceis de implementar diariamente de forma eficiente, resultando muitas vezes em dados e fluxos de trabalho confusos. Quando tal situação ocorre, a qualidade dos resultados do projeto reduz-se e pode ficar comprometida. As normas aplicadas aos BIMs construídos, exatamente como as normas aplicadas aos BIMs para edifícios novos, contribuem para a criação de informação credível e útil. Para atualizar um BIMs durante o ciclo de vida de um edifício,é necessário adquirir a informação sobre o estado actual do edifício. A monitorização de dados pode ser composta por fotografias, PCM, dados de sensores, ou dados resultantes da comparação de PCM e BIMs e podem representar uma maneira de atualizar BIMs existentes. Isto permite adicionar continuamente informações, documentando a evolução e a história da construção e possibilita avaliar possíveis intervenções de prevenção para a sua valorização. BIM não é geralmente usado para documentar edifícios existentes ou intervenções em edifícios existentes. No presente trabalho propõe-se melhorar tal situação usando standards e/ou diretrizes BIM e apresentar uma visão inicial e geral dos componentes que devem ser incluídos em tais standards e/ou linhas de orientação.
ABSTRACT: Building information modeling (BIM) is most often used for the construction of new buildings. By using BIM in such projects, collaboration among stakeholders in an architecture, engineering and construction project is improved. This scenario might also be targeted for interventions in existing buildings. This thesis intends to enhance processes of recording, documenting and managing information by establishing a set of workflow guidelines to efficiently model existing structures with BIM tools from point cloud data, complemented with any other appropriate methods. There are several challenges hampering BIM software adoption for planning interventions in existing buildings. Volk et al. (2014) outlines that the as-built BIM adoption main obstacles are: the required modeling/conversion effort from captured building data into semantic BIM objects; the difficulty in maintaining information in a BIM; and the difficulties in handling uncertain data, objects, and relations occurring in existing buildings. From this analysis, it was developped a case for devising BIM workflow guidelines for modeling existing buildings. The proposed content for BIM guidelines includes tolerances and standards for modeling existing building elements. This allows stakeholders to have a common understanding and agreement of what is supposed to be modeled and exchanged.In this thesis, the authors investigate a set of research questions that were formed and posed, framing obstacles and directing the research focus in four parts: 1. the different kind of building data acquired; 2. the different kind of building data analysis processes; 3. the use of standards and as-built BIM and; 4. as-built BIM workflows and guidelines for architectural offices. From this research, the authors can conclude that there is a need for better use of documentation in which architectural intervention project decisions are made. Different kind of data, not just geometric, is needed as a basis for the analysis of the current building state. Non-geometric information can refer to physical characteristics of the built fabric, such as materials, appearance and condition. Furthermore environmental, structural and mechanical building performance, as well as cultural, historical and architectural values, style and age are vital to the understanding of the current state of the building. These information is necessary for further analysis allowing the understanding of the necessary actions to intervene. Accurate and up to date information information can be generated through ADP and TLS surveys. The final product of ADP and TLS are the point clouds, which can be used to complement each other. The combination of these techniques with traditional RTS survey provide an accurate and up to date base that, along with other existing information, allow the planning of building interventions. As-built BIM adoption problems refer mainly to the analysis and generation of building geometry, which usually is a previous step to the link of non-geometric building information. For this reason the present thesis focus mainly in finding guidelines to decrease the difficulty in generating the as-built-BIMs elements. To handle uncertain data and unclear or hidden semantic information, one can complement the original data with additional missing information. The workflows in the present thesis address mainly the missing visible information. In the case of refurbishment projects the hidden information can be acquired to some extend with ADP or TLS surveys after demolition of some elements and wall layers. This allows a better understanding of the non visible materials layers of a building element whenever it is a partial demolition. This process is only useful if a part of the element material is removed, it can not be applied to the non intervened elements. The handling of visible missing data, objects and relations can be done by integrating different kind of data from different kind of sources. Workflows to connect them in a more integrated way should be implemented. Different workflows can create additional missing information, used to complement or as a base for decision making when no data is available. Relating to adding missing data through point cloud data generation the study cases outlined the importance of planning the survey, with all parts understanding what the project needs are. In addition to accuracy, the level of interpretation and modelling tolerances, required by the project, must also be agreed and understood. Not all survey tools and methods are suitable for all buildings: the scale, materials and accessibility of building play a major role in the survey planning. To handle the high modeling/conversion effort one has to understand the current workflows to analyse building geometry. As-built BIMs are majorly manually generated through CAD drawings and/or PCM data. These are used as a geometric basis input from where information is extracted. The information used to plan the building intervention should be checked, confirming it is a representation of the as-is state of the building. The 3D surveys techniques to capture the as-is state of the building should be integrated in the as-built BIM workflow to capture the building data in which intervention decisions are made. The output of these techniques should be integrated with different kind of data to provide the most accurate and complete basis. The architectural company should have technical skills to know what to ask for and to use it appropriately. Modeling requirements should focus primarily on the content of this process: what to model, how to develop the elements in the model, what information should the model contain, and how should information in the model be exchanged. The point clouds survey should be done after stipulating the project goal, standards, tolerances and modeling content. Tolerances and modeling guidelines change across companies and countries. Regardless of these differences the standards documents have the purpose of producing and receiving information in a consistent data format, in efficient exchange workflows between project stakeholders. The critical thinking of the modeling workflow and, the communication and agreement between all parts involved in the project, is the prime product of this thesis guidelines. The establishment and agreement of modeling tolerances and the level of development and detail present in the BIMs, between the different parts involved on the project, is more important than which of the existing definitions currently in use by the AEC industry is chosen. Automated or semi-automated tools for elements shape extraction, elimination or reduction of repetitive tasks during the BIMs development and, analysis of environment or scenario conditions are also a way of decreasing the modeling effort. One of the reasons why standards are needed is the structure and improvement of the collaboration not only with outside parts but also inside architectural offices. Data and workflow standards are very hard to implement daily, in a practical way, resulting in confusing data and workflows. These reduce the quality of communication and project outputs. As-built BIM standards, exactly like BIM standards, contribute to the creation of reliable and useful information. To update a BIMs during the building life-cycle, one needs to acquire the as-is building state information. Monitoring data, whether consisted by photos, PCM, sensor data, or data resulting from the comparison of PCM and BIMs can be a way of updating existing BIMs. It allows adding continuously information, documenting the building evolution and story, and evaluating possible prevention interventions for its enhancement. BIM environments are not often used to document existing buildings or interventions in existing buildings. The authors propose to improve the situation by using BIM standards and/or guidelines, and the authors give an initial overview of components that should be included in such a standard and/or guideline.

Cultural heritage conservation and restoration work is a complex process that includes documentation, data collection, interpretation and production. By integrating the BIM (Building Information Modeling) methodology into this process, the concept of HBIM (Historic Building Information Modeling) has been formed. In this article, the progress of this process with the HBIM methodology in the restoration, protection and management studies of cultural heritage buildings and sites requiring collective and holistic work, the evaluation of access to the information obtained, and the provision of interdisciplinary information exchange were analyzed. By using the SWOT analysis method, the opportunities and threats offered by using the HBIM working methodology were evaluated and the strengths and weaknesses of the HBIM technology were determined. As a result of the SWOT analysis, it has been determined that the HBIM application will positively contribute to the heritage structures and increase in the direction of potential opportunities by eliminating the weaknesses.

From systemic perspective reconstruction and restoration of industrial buildings are similar to historical and cultural heritage buildings. The maintenance and reuse of these buildings becoming more and more important research area worldwide. This importance must increase the information management demand but however, the most advanced digital technologies are rarely used. Use of 3D modelling technologies or whole building information modelling (BIM) methodology can help to save digital information of historic buildings is a significant effort to preserve the heritage and retain its most valuable features.

The U.S. Department of Defense (DoD) operates numerous Arctic and Subarctic installations, including Alaska. Changes to permafrost can threaten critical built infrastructure. It is critical to accurately characterize and compare site conditions in permafrost regions to enable the efficient, cost-effective design and construction of an infrastructure well suited to the permafrost environment and that meets DoD requirements. This report describes three research efforts to establish (1) field investigation approaches for ground ice detection and delineation, (2) methods and modeling for early warning detection of thawing permafrost under infrastructure, and (3) an outline of a decision support system that determines the most applicable foundation design for warming and degrading permafrost. Outcomes of these interrelated efforts address needs to improve construction of DoD mission critical infrastructure on Arctic and Subarctic permafrost terrains. Field investigation processes used systematic methodologies including borehole data and geophysical measurements to effectively characterize subsurface permafrost information. The Permafrost Foundation Decision Support System (PFFDSS) tool implements and logically links field survey information and foundation type assessments. The current version of PFFDSS is designed to be accessible to design-engineers of a broad range of experience, that will reduce the effort and cost, and improve the effectiveness of site assessment.
