Building design can have a major impact on sustainability through material efficiency and construction waste minimisation (CWM). The construction industry consumes over 420 million tonnes of material resources every year and generates 120 million tonnes of waste containing approximately 13 million tonnes of unused materials. The current and on-going field of CWM research is focused on separate project stages with an overwhelming endeavour to manage on-site waste. Although design stages are vital to achieve progress towards CWM, currently, there are insufficient tools for CWM. In recent years, Building Information Modelling (BIM) has been adopted to improve sustainable building design, such as energy efficiency and carbon reduction. Very little has been achieved in this field of research to evaluate the use of BIM to aid CWM during design. However, recent literature emphasises a need to carry out further research in this context. This research aims to investigate the use of BIM as a platform to help with CWM during design stages by developing and validating a BIM-aided CWM (BaW) Framework. A mixed research method, known as triangulation, was adopted as the research design method. Research data was collected through a set of data collection methods, i.e. selfadministered postal questionnaire (N=100 distributed, n=50 completed), and semistructured follow-up interviews (n=11) with architects from the top 100 UK architectural companies. Descriptive statistics and constant comparative methods were used for data analysis. The BaW Framework was developed based on the findings of literature review, questionnaire survey and interviews. The BaW Framework validation process included a validation questionnaire (N=6) and validation interviews (N=6) with architects. Key research findings revealed that: BIM has the potential to aid CWM during design; Concept and Design Development stages have major potential in helping waste reduction through BIM; BIM-enhanced practices (i.e. clash detection, detailing, visualisation and simulation, and improved communication and collaboration) have impacts on waste reduction; BIM has the most potential to address waste causes (e.g. ineffective coordination and communication, and design changes); and the BaW Framework has the potential to enable improvements towards waste minimisation throughout all design stages. Participating architects recommended that the adoption of the BaW Framework could enrich both CWM and BIM practices, and most importantly, would enhance waste reduction performance in design. The content should be suitable for project stakeholders, architects in particular, when dealing with construction waste and BIM during design.

This thesis deals with the BIM creating process with the use of laser scanning data in Revit software. It’s focusing mainly on MEP of water object. In the theoretical part of thesis there are outlined basic issues about laser scanning, informational modelling and other relating issues. In the practical part of the thesis is the summarization of procedure starting from data collecting, data processing to the procedure of creating BIM model, it’s visualisation and the use of the model. There are also mentioned useful pieces of knowledge, which I have learned during dealing with the problems related to the application of this new way of using the spatial information.

Whilst the amount of information readily available to workers in information- and knowledge intensive business- and industrial contexts only seem to increase with every day, those workers still have difficulties in finding relevant and needed information as well as storing, distributing, and aggregating such information. Yet, whilst there exist numerous technical, organisational, and practical approaches to remedy the situation, the problems seem to prevail. This publication describes the first part of the author’s work on defining a methodology for improving the flow of work related information, with respect to the information demand of individuals and organisations. After a prefatory description of the perceived problems concerning information flow in modern organisations, a number of initial conjectures regarding information demand and use in small-scale business contexts are defined based on a literature study. With this as the starting point the author sets out to, through an empirical investigation performed in three different Swedish organisations during 2005, identify how individuals within organisations in general, and these three in particular, use information with respect to such organisational aspects as roles, tasks, and resources as well as spatio-temporal aspects. The results from the investigation are then used to validate the conjectures and to draw a number of conclusions on which both a definition of information demand, as well as the initial steps towards defining a methodology for information demand analysis, are based. Lastly, a short discussion of the applicability of the results in continued work is presented together with a description of such planned work.

The technology of Building Information Modelling (BIM) is being introduced to the Architectural, Engineering and Construction (AEC) industry. This industry is generally perceived as being fragmented, having low productivity and with a low rate of innovation. BIM is presented as new paradigm within this industry, enabling inter-organisational collaboration, overall increasing quality while simultaneously lowering costs. But widespread BIM implementation has not yet taken place. In order to increase adoption, public client organisations have been argued to be the actors needed to initiate and drive the implementation of BIM. However, the client perspective of such implementation initiatives has not been the main focus of earlier research. In this licentiate thesis the BIM implementation process conducted by the largest infrastructure client in Sweden is analysed. This organisation implements BIM both to benefit their own organisation but also to increase productivity and innovation within the whole infrastructure branch of the AEC-industry. With the purpose of increasing the understanding of technology driven change processes at public client organisations, the BIM implementation at this organisation is analysed as an empirical example.  The case study is analysed by a theoretical framework taking inspiration from Actor-Network theory and Sociology of Translation. Based on this analysis the translation process, where key actors are identified and enrolled into using BIM are described. The analysis reveals a complex network of actors linked to the implementation in question. Instead of a single BIM concept, several different and sometimes conflicting interpretations of BIM are simultaneously being translated. This licentiate thesis problematizes the role of client organisations in initiating change within a network of actors. The main ways of enrolling actors into using BIM have in the studied case been the development of new demand documents. This strategy has however been problematic as the new demands for BIM have not been accepted as intended within many construction projects. Instead, the results of this thesis argue for the importance of client organisations as negotiators, not only needed to establish demand for a new innovation. / Tekniken Byggands Informations Modellering (BIM) introduceras just nu i byggbranschen. Denna bransch beskrivs ofta som varande fragmenterad med låg produktivitet samt bristande innovationskraft. BIM beskrivs som ett nytt paradigm för denna bransch, möjliggörande interorganisatoriskt sammarbete, ökad kvalitet och samtidigt minskande kostnader. Däremot har BIM ännu inte anammats på bred front. För att öka implementeringstakten har statliga beställarorganisationer beskrivits som de aktörer som behövs för att initiera och driva implementeringen av BIM. Dock har tidigare forskning inte fokuserat på beställarperspektivet kring sådana initiativ. I denna licentiatavhandling presenteras en fallstudie av BIM implementeringen på den största infrastrukturbeställaren i Sverige. Denna organisation implementerar BIM både för att gynna den egna organisationen men också för att öka produktiviteten och innovationstakten i intrastrukturbranschen som helhet. Med syfte att öka förståelsen kring beställarrollen i förhållande till teknikdrivna förändringsprocesser studeras denna förändringsprocess som ett empiriskt exempel. Denna fallstudie analyseras utifrån ett teoretiskt ramverk med inspiration tagen från Actor-Network Theory och Sociology of Translation. Utifrån denna analys beskrivs översättningsprocesser där nyckelaktörer identifieras och försöks knytas till att använda BIM. Analysen visar på ett komplext nätverk av aktörer kopplat till implementeringen i fråga. Istället för ett enskilt BIM koncept hittas ett flertal samtidiga, och stundtals motsägelsefulla tolkningar av BIM som alla samtidigt översätts i organisationen. Denna licentiatavhandling problematiserar beställarrollen i relation till initiering av förändring inom ett aktörsnätverk. Det huvudsakliga sättet genom vilket aktörer knyts till att använda BIM har i det studerade fallet varit genom utveckling av nya kravdokument. Denna strategi har däremot varit problematisk då dessa krav inte accepterats som tänk inom ett flertal byggprojekt. Istället visar resultatet av denna studie på vikten av beställarorganisationer som varande förhandlare, inte endast viktiga för att upprätta efterfrågan för en ny innovation. / <p>QC 20170614</p>

The building sector is one of the largest energy consumers and there are global efforts toward sustainable and energy-efficient new buildings and existing buildings retrofit. The application of Building Information Modelling (BIM) in environmental assessment was practiced and studied following the increasing number of projects adopting the BIM workflows and pursuing green building certifications. The interest of this thesis is to study the use of different Building Information Modelling tools used globally for energy and environmental assessment to examine their practical benefits and challenges. Case studies of two primary school buildings that achieved the Swedish Miljöbyggnad system were used to compare what could have been achieved with Leadership in Energy and Environmental Design (LEED) categories of energy and atmosphere and indoor environmental quality to what has been achieved in similar Miljöbyggnad areas. A review and summary of energy and atmosphere and indoor environmental categories in the LEED version 4 user’s guide is presented to evaluate the case study potential score in them. The early adoption of modeling in the evaluation from the conceptual design is the best approach to achieve better performance. It will improve the way of working and result in a more efficient and sustainable building. The Building Information Modelling software can be used directly in assessment using the integrated modules within the popular authoring tools such as Revit’s lighting and Insight the cloud base service or by transferring the model data to a stand-alone tool like IDA-ICE. The energy plug-ins of the authoring tools such as Revit are still lacking full control over the analytical model and the limited input options. The identified and discussed advantages of Building Information Modelling implementation are collaboration, accuracy, time, and cost saving. Data exchange issues, knowledge, and the differences in assessment tools were discussed as implementation barriers. Although the full comparison of certification systems is difficult, the comparison between the potential LEED score and achieved Miljöbyggnad rating showed some differences and similarities in the rating systems. The comparison requires rearranging the rating system indicators into unified categories. The framework that compares the scope, structure, content, and aggregation, would give a meaningful comparison. The way that the LEED and Miljöbyggnad are rewarding the indicators and the aggregation of aspects towards the final rating is totally different.

Im Rahmen dieser Masterarbeit wurden die Arbeitsmethoden der Tragwerksplanung eines Ingenieurbüros im Zusammenhang mit der fortschreitenden Digitalisierung innerhalb der Baubranche untersucht. Konkret sollen die Einflüsse und Möglichkeiten von Building Information Modeling auf interne Prozesse und die damit verbundene Effektivität analysiert werden. Das Ziel der Arbeit ist die Identifikation der Produktivität des bestehenden Workflows und einem anschließenden Vergleich mit dem im Zuge dieser Arbeit entwickelten angepassten Workflow, welcher sich im Optimalfall als effektiver herausstellt. Dieser Vergleich soll an einem Fallbeispiel, dem Neubau eines 16-geschossigen Wohnquartiers in Jena stattfinden. Dafür wird der projektbezogene Bestandsworkflow in die verschiedenen Arbeitsschritte zerlegt, strukturiert und dahingehend systematisch beschrieben. Danach erfolgt in einer ähnlichen Vorgehensweise die Entwicklung eines angepassten Workflows, welcher ebenfalls zunächst vorgestellt wird. Diese beiden Workflows werden abschließend hinsichtlich verschiedener Parameter miteinander verglichen, um eine Bewertung der Effektivität treffen zu können. Dafür werden beide Arbeitsweisen der Tragwerksplanung anhand des gleichen Schemas analysiert. Im Zuge der Analyse des angepassten Workflows erfolgt die projektbezogene Beschreibung, um eine genaue Vergleichbarkeit zu Gewährleisten. Innerhalb der abschließenden Gegenüberstellung konnten signifikante Unterschiede bezüglich der zuvor definierten Parameter festgestellt werden. Die mit der Digitalisierung verbundene BIM-Methode kann die Arbeitsweisen der Tragwerksplanung in einem Ingenieurbüro maßgeblich beeinflussen. Vor dem Hintergrund der begrenzten personellen und finanziellen Ressourcen kleinerer Unternehmen bietet eine Anpassung der Workflows völlig neue Potenziale und kann als Chance angesehen werden, um die eigene Wettbewerbsposition nachhaltig zu stärken.:Abbildungsverzeichnis Abkürzungsverzeichnis 1 Einleitung 1.1 Problemstellung 1.2 Ziele und Struktur der Arbeit 2 Bauvorhaben „Solar-Quartiers“ in Jena 2.1 Projektvorstellung – Fallbeispiel 2.2 Ökonomischer Zielkonflikt zwischen den Beteiligten 3 Erläuterung der Ausgangssituation im Ingenieurbüro Hubert Beyer 4 Erläuterung von BIM-Workflows 4.1 Workflow 1: Projektbezogener Bestandsworkflow 4.1.1 Aufstellung von statischen Berechnungen 4.1.2 Modellorientierte Kommunikation zwischen den Planungsbeteiligten 4.2 Workflow 2: Angepasster projektbezogener Workflow 4.2.1 Aufstellung von statischen Berechnungen 4.2.2 Modellorientierte Kommunikation zwischen den Planungsbeteiligten 5 Analyse der betrachteten BIM-Workflows 5.1 Bestandsworkflow 5.2 Angepasster projektbezogener Workflow 5.3 Vergleich beider Workflows und Analyse der Zielerreichung 5.4 Analyse hinsichtlich des ökonomischen Zielkonfliktes 6 Zusammenfassung und Ausblick Literaturverzeichnis Eidesstattliche Erklärung / As part of this master's thesis, the working methods of structural planning of an engineering office were examined in the context of the progressive digitalization within the construction industry. Specifically, the influences and possibilities of building information modelling on internal processes and the associated effectiveness will be analysed. The aim of the work is to identify the productivity of the existing workflow and then compare it with the adapted workflow developed in the course of this work, which in the optimal case turns out to be more effective. This comparison will take place based on a concrete case example, the new construction of a 16-storey residential quarter in Jena. For this purpose, the project-related inventory workflow was first broken down into the different work steps, structured and described systematically. Afterwards, an adapted workflow was developed using a similar approach, which was also presented initially. Finally, these two workflows should be compared with each other regarding different parameters to be able to make an evaluation regarding effectiveness. For this purpose, both methods of structural design were analysed below based on the same scheme. In the course of the analysis of the adapted workflow, the project-related description is carried out to ensure exact comparability. Within the final comparison, significant differences with respect to the previously defined parameters could be observed. The BIM method associated with digitization can significantly influence the working methods of structural planning in an engineering office. Given the limited human and financial resources of smaller companies, adapting their workflows offers completely new potential and can be seen as an opportunity to sustainably strengthen their competitive position.:Abbildungsverzeichnis Abkürzungsverzeichnis 1 Einleitung 1.1 Problemstellung 1.2 Ziele und Struktur der Arbeit 2 Bauvorhaben „Solar-Quartiers“ in Jena 2.1 Projektvorstellung – Fallbeispiel 2.2 Ökonomischer Zielkonflikt zwischen den Beteiligten 3 Erläuterung der Ausgangssituation im Ingenieurbüro Hubert Beyer 4 Erläuterung von BIM-Workflows 4.1 Workflow 1: Projektbezogener Bestandsworkflow 4.1.1 Aufstellung von statischen Berechnungen 4.1.2 Modellorientierte Kommunikation zwischen den Planungsbeteiligten 4.2 Workflow 2: Angepasster projektbezogener Workflow 4.2.1 Aufstellung von statischen Berechnungen 4.2.2 Modellorientierte Kommunikation zwischen den Planungsbeteiligten 5 Analyse der betrachteten BIM-Workflows 5.1 Bestandsworkflow 5.2 Angepasster projektbezogener Workflow 5.3 Vergleich beider Workflows und Analyse der Zielerreichung 5.4 Analyse hinsichtlich des ökonomischen Zielkonfliktes 6 Zusammenfassung und Ausblick Literaturverzeichnis Eidesstattliche Erklärung

The concept of BIM is nascent but evolving rapidly, thus, its deployment has become the latest shibboleth amongst both academics and practitioners in the construction sector in the recent couple of years. Due to construction clients buy-in of the BIM concept, the entire industry is encouraged to pursue a vision of changing work practices in line with the BIM ideas. Also, existing research recognises that the implementation of BIM affects all areas of the construction process from design of the building, through the organisation of projects, to the way in which the construction process is executed and how the finished product is maintained. The problem however is that, existing research in technology utilisation in general, and BIM literature in particular, has offered limited help to practitioners trying to implement BIM, for focusing predominantly, on technology-centric views. Not surprisingly therefore, the current BIM literature emphasises on topics such as capability maturity models and anticipated outcomes of BIM rollouts. Rarely does the extant literature offer practitioners a cohesive approach to BIM implementation. Such technology-centric views inevitably represent a serious barrier to utilising the inscribed capabilities of BIM. This research therefore is predicated on the need to strengthen BIM implementation theory through monitoring and analysing its implementation in practice. Thus, the focus of this thesis is to carry out a sociotechnical systems (STS) analysis of BIM implementation in construction organisations. The concept of STS accommodates the dualism of the inscribed functions of BIM technologies and the contextual issues in the organisations and allows for the analysis of their interactive combination in producing the anticipated effect from BIM appropriation. An interpretive research methodology is adopted to study practitioners through a change process, involving the implementation of BIM in their work contexts. The study is based on constructivist ontological interpretations of participants. The study adopts an abductive research approach which ensures a back-and-forth movement between research sites and the theoretical phenomenon, effectively comparing the empirical findings with the existing theories and to eventually generate a new theoretical understanding and knowledge regarding the phenomenon under investigation. A two-stage process is also formulated for the empirical data collection - comprising: 1) initial exploratory study to help establish the framework for analysing BIM implementation in the construction context; and 2) case studies approach to provide a context for formulating novel understanding and validation of theory regarding BIM implementation in construction organisations. The analysis and interpretation of the empirical work follows the qualitative content analysis technique to observe and reflect on the results. The findings have shown that BIM implementation demands a complete breakaway from the status quo. Contrary to the prevailing understanding of a top-down approach to BIM utilisation, the study revealed that different organisations with plethora of visions, expectations and skills combine with artefacts to form or transform BIM practices. The rollout and appropriation of BIM occurs when organisations shape sociotechnical systems of institutions, processes and technologies to support certain practices over others. The study also showed that BIM implementation endures in a causal chain of influences as different project organisations with their localised BIM ambitions and expectations combine to develop holistic BIM-enabled project visions. Thus, distributed responsibilities on holistic BIM protocols among the different levels of influences are instituted and enforced under binding contractual obligations. The study has illuminated the centrality of both the technical challenges and sociological factors in shaping BIM deployment in construction. It is also one of the few studies that have produced accounts of BIM deployment that is strongly mediated by the institutional contexts of construction organisations. However, it is acknowledged that the focus of the research on qualitative interpretive enquiry does not have the hard and fast view of generalising from specific cases to broader population/contexts. Thus, it is suggested that further quantitative studies, using much larger data sample of BIM-enabled construction organisations could provide an interesting point of comparison to the conclusions derived from the research findings.

Syfte: Byggsektorn karaktäriseras av att till stor del bestå av temporära projektorganisationer med mycket samarbete mellan discipliner men utan någon vidare processkontinuitet mellan de unika projekten. Det finns ett stort fokus på tid och omedelbar handling som en del av aktörernas referensram och varje aktivitet och nytt arbetssätt bör ge omedelbara fördelar i form av tidsvinster och effektivare utförande för att villigt accepteras. Behoven av standardiserade arbetssätt blir mycket synliga när man börjar införa BIM i projekten. Att aktivt använda BIM-modellen på bygget skapar krav på innehållet och att man följer ett projekteringsschema. BuildingSMART International (2010) skriver: ”Om den nödvändiga informationen är tillgänglig när den behövs och kvalitén på informationen är tillfredställande, så blir själva byggprocessen signifikant förbättrad”. Målet med detta examensarbete är att ta fram ett förslag på hur sekvensen av informationsleveranser bör se ut för den inledande produktionen av bärande system i en totalentreprenad. Metod: För att nå målet har en litteraturstudie genomförts för att skapa arbetets teoretiska ramverk. En fallstudie på en totalentreprenad med djupgrundläggning har genomförts. I fallstudien har empiri insamlats genom intervjuer med några av projektets aktörer samt en dokumentanalys av relevanta ritningar, protokoll och övriga dokument i projektet. Resultat: Rapporten har kartlagt sekvensen av informationsleveranser (inklusive vilket informationsinnehåll och vilken detaljeringsnivå de behöver ha) för den inledande produktionen av bärande system i en totalentreprenad. Detta kunskapsbidrag med processkarta och informationsbehov kan byggas vidare på, för att kunna implementeras i BIM-verktygen och därigenom underlätta arbetet och föra BIM-användningen framåt. Konsekvenser: Rapporten har med ovan resultat bidragit med några påbörjade pusselbitar i ett stort pussel av information och leveranser i rätt sekvens och detaljeringsgrad. För att pusslet ska bli komplett måste även informationsleveranser från förfrågningsunderlaget fungera korrekt. Arbetet har belyst fördelar att arbeta med BIM i denna del av byggprocessen. Rapporten föreslår förtydligande av innebörd genom att ha både detaljeringsnivå och utvecklingsnivå som benämningar i Sverige. Begränsningar: Rapporten begränsas till att beskriva vad byggentreprenören behöver för informationsleveranser från konstruktören som rör pålning, grundsulor och fundament. Rapporten beskriver också de informationsleveranser konstruktören behöver för att uppfylla byggentreprenörens informationsbehov. / Purpose: The building industry is characterised by mainly consisting of temporary project organizations with much interdisciplinary cooperation but with little continuity of process between the unique projects. There is a big focus on time and immediate action as part of the actors’ frame of reference, and every activity and new work method should give immediate advantages in time savings and more efficient work to be readily accepted. The need for standardised work methods is very visible when BIM is introduced in the projects. To actively use the BIM-model on site creates demands on the content and that a design schedule is followed. BuildingSMART International (2010) writes: ”If the information required is available when it is needed and the quality of information is satisfactory, the construction process will itself be significantly improved”. The aim of this work is to produce a suggestion of how the sequence of information deliveries should be in the starting production of the loadbearing system in a design build project. Method: To reach the aim a literature study has been conducted to create the theoretical framework for the study. A case study has been conducted on a design build project with a deep foundation. Empirical data has been collected by means of interviewing some of the project actors and conducting a document analysis of project documents such as drawings and protocols. Findings: The report has mapped the sequence of information deliveries (including what information content and what level of development they need to have) for the initial production of the loadbearing system in a design build project. This contribution of knowledge with the process map and information demands can be built upon, to allow for implementation in the BIM tools and thus make the work easier and push the use of BIM forward. Implications: With the above results the report has contributed with a few started puzzle pieces in a big puzzle of information and deliveries in the correct sequence and level of development. To complete the puzzle the information deliveries from the specifications also needs to work correctly. The report has shown advantages by working with BIM in this part of the building process. The report suggests clarification of meaning by using both names, level of detail and level of development, in Sweden. Limitations: The report is limited to describe what information deliveries the contractor needs from the structural designer when it comes to piling and foundations. It also describes the information deliveries needed by the structural designer to be able to meet the information need of the contractor.

Em decorrência de sua atuação expressiva no mercado de financiamento de empreendimentos de habitação e infraestrutura, a Caixa Econômica Federal (Caixa) é um banco de grande relevância para o setor da construção civil brasileira. A Caixa mantém um setor técnico no qual são desempenhadas, dentre demais responsabilidades, as atividades de análise de documentação técnica e verificação da execução orçamentária e financeira das obras. Atualmente, esses procedimentos são realizados essencialmente de forma manual, configurando um processo moroso e suscetível à ocorrência de imprecisões. Nesse sentido, o presente trabalho tem como objetivo analisar a introdução da Modelagem da Informação da Construção, notadamente, no processo de verificação da documentação técnica de obras, realizado pelos profissionais desse banco público. Primeiramente, realizou-se um diagnóstico, por meio de uma survey, no setor técnico da Caixa que apontou aspectos relevantes à gestão de mudanças de origem tecnológica nesse ambiente. Em continuidade ao estudo de caso, investigou-se as motivações, os benefícios almejados e as possíveis barreiras para a implantação dessa inovação no processo de análise técnica desenvolvido pela instituição. Para verificar a adequabilidade e a aceitação das propostas preliminares de ferramentas e diretrizes de modelagem foi conduzido um workshop no qual participaram profissionais voluntários do mercado da construção civil. Com base neste estudo, apresentado neste trabalho na forma de três artigos científicos publicados, verificou-se que a Caixa pode ser considerada um importante vetor de difusão de práticas associadas à Modelagem da Informação da Construção na indústria da construção civil brasileira e que a proposição de novas ferramentas e diretrizes poderia ser efetivamente adequada para incrementar a prática projetual. Além disso, observou-se que a transformação interna necessária para a implementação de mudanças nos processos técnicos da Caixa é viável desde que seja propiciado um ambiente favorável, em que os gestores incentivem, planejem e deem suporte às possíveis mudanças. Finalmente, a contribuição pretendida com esta pesquisa é fomentar outras iniciativas e colaborar para a disseminação da Modelagem da Informação da Construção nos setores de projeto e construção civil brasileiros. / Due to its outstanding performance in housing and infrastructure construction financing market, Caixa Econômica Federal (Caixa) is a bank of great importance in the Brazilian Construction and Design industry. Caixa maintains a technical department that, among other activities, perform technical feasibility analyses, and verify the budgetary and financial development of construction projects. Currently, the project analysis process is manual, time-consuming and error-prone. In this sense, the present study aims to analyse the introduction of Building Information Modelling in the technical feasibility analyses process, carried out by engineers and architects. Firstly, a survey was conducted to perform an intraorganizational assessment of Caixa\'s technical department, in order to identify aspects relevant to change management. Secondly, in this study case, the motivations, the desired benefits and potential barriers to the implementation of this innovation were investigated. In addition, a workshop was conducted with construction and design professionals to verify the suitability and acceptance of the preliminary proposals of tools and modelling guidelines. Based on this study presented in three published scientific papers, Caixa can be considered an important diffusion vector of Building Information Modelling practices in the Brazilian construction and design industry. In addition, the proposition of new tools and modelling guidelines could effectively be appropriate to enhance its design practices. Furthermore, the intraorganizational change required for implementing innovations in the Caixa technical department proved to be feasible if provided with a favourable environment in which managers stimulate, plan and support possible changes. Finally, the intended contribution of this research is to encourage other initiatives and contribute to spreading additional practices related to Building Information Modelling in the Brazilian construction and design industry.

Nos últimos anos, a discussão sobre a implementação do conceito de modelagem da informação da construção tem permanecido nas pautas das empresas do setor da construção civil em todo o mundo; no entanto, no cenário brasileiro, o descompasso entre a estratégia setorial e as iniciativas individuais de algumas empresas tem chamado a atenção. Partindo do princípio de que o conceito de modelagem da informação da construção, em função do seu caráter de inovação tecnológica, carrega consigo a necessidade de mudanças, a reflexão e adaptações sobre os diversos processos que permeiam a produção dos empreendimentos de construção torna-se fundamental. Nesse contexto, o objetivo desta tese é propor um conjunto de Diretrizes para Gestão do Processo de Projeto em Empresas Incorporadoras e Construtoras. As Diretrizes estão pautadas na necessidade de definir o projeto como um processo estratégico, inserindo a sua gestão como elemento fundamental para a facilitação e integração do fluxo de informações no âmbito do empreendimento. Para a concretização do objetivo da tese, realizaram-se Estudos de Caso em empresas Incorporadoras e Construtoras brasileiras com o objetivo de diagnosticar as práticas vigentes de gestão do processo de projeto. Em paralelo, conduziu-se a reflexão sobre as responsabilidades do gestor do processo de projeto no âmbito da modelagem por meio de Grupos de Foco envolvendo gestores do processo de projeto e especialistas em tecnologia da informação aplicada à construção. Além disso, a metodologia de pesquisa contempla um Estudo de Caso com foco para a implementação do Conceito de Modelagem da Informação no contexto setorial do Reino Unido. Como resultado das Diretrizes, apresenta-se o Modelo para Gestão do Processo de Projeto no Contexto da Modelagem, seguido pelo Plano de Reestruração para o Departamento de Projetos, o qual visa à proposição de um modelo estruturado para condução das mudanças necessárias nas áreas responsáveis pelo processo de projeto das empresas Incorporadoras e Construtoras. / The discussion about BIM (Building information Modelling) implementation has remained on the agendas of construction companies worldwide in recent years; however, in the Brazilian context, the gap between the industry strategy and few companies which have decided to implement BIM autonomously has been the main aspect that draw attention. Assuming BIM as a technological innovation, which carries with it changes, it is fundamental to analyse and adapt the design and construction processes. In this context, the thesis aims propose a set of Guidelines to Manage the Design Process of Brazilian Real Estate Development Companies. The Guidelines has taken the Design Management as a strategic process which must facilitate and integrate information flow among the Construction Project agents. In order to achieve the objective of Thesis, Case Studies have carried out in order to diagnose the design management current practices in the Brazilian Real Estate Development Companies. Aiming to discuss the Design managers\' responsibilities in contexts where BIM is applied, Focus Groups were organized and Design Managers, BIM specialists and also Academics have participated in the discussions sections. In addition, the research methodology have included a Case Study focusing on the BIM implementation in United Kingdom construction industry. As results and Guidelines, the Design Management Modeling in BIM context, followed by the Restructuring Planning are proposed. The Restructuring Planning was defined specifically for Real Estate Development Companies and aims to propose structured way, comprehending processes which should be re-designed and a set of steps for driving the necessary changes in order to use Design Management Guide in BIM context are proposed.
