The AEC (Architecture, Engineering, and Construction) industry has been undergoing a significant digitaliza-tion process in the last years. This transformation implies new challenges and adaptation concerning the ex-change of data between different software applications. Therefore, in response to this problem the benefits of IFC as a solution for the exchange of data have been investigated. However, the current versions of IFC cannot achieve semantic clarity in mapping entities and relationships. Therefore, there have been several attempts to develop solutions and optimizing methods to improve the exchange of information of product data. This paper aims to identify and investigate the challenges of using product data templates (PDT) for exchange of infor-mation and different PDT has been evaluated and compared. The necessary data was collected through literature review and document analysis. Five challenges and five initiatives were identified during the literature review. The five initiatives are Semantic web and linked data, CoClass, Buildingsmart, COBie and Cobuilder. The result showed how these initiatives could solve the identified challenges.

The thesis is an outcome of a collaborative work between the author and the renovation team of Modexa AB on project of housing renovation of Tyresö municipality ( Ekbacken ). During this thesis we tried to analyse the ongoing process of renovation in Stockholm and try to provide a solution which helps to improve the data gathering and analysis by production of the BIM model. Further studies to provide further details about the possible outcomes of the BIM model and integration with other software for energy studies, project management and building management had been done.

A well-structured and coordinated information management practice is central to promoting efficiency in construction. Building information management encompasses authoring, interpretation, communication, coordination and storage of building information. The benefits envisioned by utilizing IT developments such as Building Information Modelling (BIM) in the facility management and operations (FM&amp;O) sector are estimated to be far greater than in other sectors. There is, however, a gap between the knowledge available in the field of building information management and the actual demands of the architectural, engineering, construction and operation (AECO) industry, especially the FM&amp;O sector. The overall aim of this qualitative research is to develop knowledge that conceptualizes the lifecycle supporting implementation of BIM in the AECO industry with a focus on its implications for a BIM-enabled FM&amp;O practice. This applied research comprises a number of summative and formative components: paper 1 investigates the existing and emerging information management systems for the FM&amp;O sector and their characteristics. The focus of paper 2 is narrowed down to the technical requirements on building information management systems; while its temporal scope spans the entire lifecycle of buildings. Paper 3 is a further elaboration on the findings of paper 1 and covers the technical requirements of BIM-implementation in the FM&amp;O sector. Paper 4 investigates workflows – another category of the issues identified in paper 1. Paper 1 aims to provide a general understanding of the importance and implications of implementing BIM-enabled systems in the FM&amp;O sector and also identifies the main categories of the issues associated with this approach. This literary paper reports on a basic research with a descriptive approach and builds upon the information from a non-exhaustive set of literature. In this paper, workflows, contracts and information technology have been identified as three categories of the issues associated with implementing BIM-enabled systems in the FM&amp;O sector. Paper 2 is also a literary research which draws on the notion of BIM repositories and aims to clarify the technical requirements for a more collaborative building industry as well as depicting the current status of building knowledge management technologies, recent trends and future prospects. Open format BIM repositories have been suggested as the cornerstones of an integrated information management system for AECO firms. The aim of paper 3 is twofold: firstly, to summarize the current status of the building information management technologies applied in the facility operation activities and identifying prevailing issues; secondly, to devise some technical solutions for those issues based on a case project. In the first part of this study, a summarized description of information management configurations in eleven projects were extracted from literature and the technical issues within those systems were identified. Moreover, five major categories of contemporary technical solutions for enhancing information transfer from BIM to FM&amp;O software were designated. Then, a narrative and illustrative representation and reconstruction of an IT-implementation project was developed. Paper 4 is another literary study which aims to provide the theoretical basis for more focused studies on existing and desired processes in the FM&amp;O sector and their associated information transactions. In this paper, firstly, the more common definitions of the key concepts have been revisited and discussed. Then, the generic types of the processes, activities and organizational roles common to FM&amp;O firms, the types of information required by each actor and how such information are acquired have been presented. / <p>QC 20150423</p>

The implementation of digital tools, such as building information modeling (BIM) in lowand middle income countries’ (LMIC) infrastructure projects has increased in interest. LMICsuch as Somalia are in need of new road construction and improved infrastructure. The purpose of this thesis study is to explore perceived challenges of implementing digital tools in the construction sector in LMIC. To provide a more detailed and in-depth insight, the thesis study has been performed through an interview study in Somalia. Since the interest is in perceptions and experiences about the implementation of digital tools, a qualitative method was chosen. Respondents were selected from the construction sector that has been interviewed about their experiences of the implementation of digital tools. The study has used Kotter's 8-step process for change as an analytical framework to analyze and discuss the empirical findings.  The results show that the most critical challenges to implementing digital tools in a LMIC ssuch as Somalia are:- lack of financial resources for investing in digital tools on large infrastructure projects- lack of overall experience and competence in the use of digital tools- lack of regulations for digital tools from the public client The study suggests the public client, who in this case is the Ministry of Public Works and Reconstruction and Housing (MPWR) that are responsible for the laws and regulations in the Somalian construction sector to take these critical challenges into consideration. The public client has the overall responsibility and influence over the construction of the infrastructure and in order to increase the implementation of digital tools in the future, it is necessary that the public client establishes follow-ups and evaluations. / Implementering av digitala verktyg, såsom byggnadsinformationsmodellering (BIM), i lågoch medelinkomstländers (LMIC) infrastrukturprojekt har ökat i intresse. LMIC, såsom Somalia, är i behov av nya vägbyggen och förbättrad infrastruktur. Därmed är syftet med denna studie att utforska och granska implementeringen av digitala verktyg för byggsektorn i LMIC. För att ge en mer detaljerad och fördjupad inblick i implementeringen av digitala verktyg i ett utvecklingsland har examensarbetet genomförts genom en intervjustudie i Somalia.  Eftersom fokus ligger på människors uppfattningar och erfarenheter av implementeringen av digitala verktyg i Somalia har en kvalitativ forskningsmetod valts. Ett antal respondenter utifrån specificerade kriterier valdes ut från byggsektorn för att intervjuas om sina erfarenheter av implementering av digitala verktyg. Studien har använt Kotters 8-stegprocessför förändring som ett analytiskt ramverk. Resultaten från studien visar att de mest kritiska utmaningarna för att implementera digitala verktyg i Somalia är brist på:- ekonomiska resurser för investering i digitala verktyg i långvariga infrastrukturprojekt- helhetsförförståelse och kompetens vid användning av digitala verktyg- saknande av regelverk kring digitala verktyg från den offentliga uppdragsgivaren Studien föreslår för den offentliga uppdragsgivaren, som i detta fall är ministeriet för offentliga arbeten och återuppbyggnad och bostäder (MPWR) som ansvarar för lagar och regler i den somaliska byggsektorn att ta hänsyn till dessa kritiska utmaningar för att skapa bättre förutsättningar för implementering av digitala verktyg. Den offentliga beställaren har det övergripande ansvaret och inflytandet över byggandet av infrastruktur och för att öka implementeringen av digitala verktyg i framtiden är det nödvändigt att den offentliga beställaren etablerar uppföljningar och utvärderingar.
