Utmaningar med implementering av BIM genom hela värdekedjan : en analys av informationsgap i BIM-projekt med stöd av innovationsteori / Challenges when implementing BIM throughout the value chain : An analysis of information gaps in BIM-projects with support of innovation theory

Klint, Axel, Strand, Fabian January 2021 (has links)
Digitalisering är ett ämne som ständigt diskuteras och har på senare år utvecklats på många plan. Inom byggbranschen har BIM (Byggnadsinformationsmanagement) länge setts som en digital lösning vilken kan tänkas utveckla branschen inom flera områden, men trots det är den digitala utvecklingen inom branschen relativt låg vilket kan ge indikation på lägre produktivitet. Särskilt om man jämför med vad som faktiskt kan uppnås vid implementering av BIM fullt ut genom värdekedjan i projekt. Det finns en brist på tidigare studier kring varför det finns ett informationsgap mellan aktörer genom hela värdekedjan som delvis kan förklara denna låga produktivitet. Syftet med denna studie är därmed att undersöka vilka utmaningar som finns vid implementeringen av BIM i hela värdekedjan av projekt och vad utmaningarna skapar för informationsgap mellan design/konstruktion- och förvaltningssidan inom ett projekt.     För att besvara syfte och frågeställningar har innovationsteori samt investeringsteori använts, där fokus främst riktats på innovationsteori. Med hjälp av teorierna kunde utmaningar med implementeringen av BIM och eventuella informationsgap som uppstår studeras djupare. I studien genomfördes åtta semistrukturerade intervjuer med fastighetsbolag, arkitekturbolag, konsultbolag och intresseorganisation.      De existerande utmaningarna vid implementering av BIM hos olika aktörer, som kan ligga till grund för försämrad interoperabilitet, kan förklaras med att avsaknad av gemensamma branschstandarder, avsaknad av en central BIM-samordnare och generellt sett låg utbildningsnivå kring vad BIM är. Det noteras att ett informationsgap finns mellan aktörer som arbetar på förvaltningssidan kontra design/konstruktion och detta kan dels förklaras på grund av motvilja att anpassa sig till nya lösningar enligt innovationsteori, dels på grund av avsaknad av gemensamma branschstandarder. Att en aktör i projektskedet inte anser det lämpligt att använda BIM kan förklaras eftersom kostnaden hittills inte alltid understiger nyttan.      Implementeringsfasen hos olika aktörer genom värdekedjan varierar och därmed kan branschen i vissa fall tolkas som trögflytande, bland annat på grund av frånvaro av öppna standarder och de språkbarriärer mellan program som kan uppstå vid användning av olika BIM-system. För att vidareutveckla arbetet kring ämnesfrågan behöver ytterligare studier genomföras kring proprietära rättigheter och problem vid anbudskalkylering, offentlig sektors påverkan på utveckling kring gemensamma branschstandarder, extern och intern BIM-samordning kopplat till effektivare projektledning och även hur gemensamma branschstandarder påverkar olika aktörer i hela värdekedjan av ett projekt. / Digitalization is constantly being discussed and has in recent years developed on many levels. Building information management, further described as BIM, has long been considered a digital solution in the construction and management industry. A solution that suitably would develop the industry in several areas. Despite this, digital development is relatively low which may indicate lower productivity than can be achieved. There is a lack of previous studies on why there is an information gap between stakeholders throughout the value chain that can partly explain low productivity and low effective stakeholder efficiency. The purpose of this study is thus to investigate the existing difficulties in the implementation of BIM in the entire value chain and what these difficulties lead to, such as information gaps between the design, construction and management side within a project.    The findings of the study are explained with support of innovation theory and investment theory, with main focus on innovation theory. With support of the theories, difficulties with implementation of BIM for stakeholders and any information gaps that arise have been studied more deeply. This study conducted eight semi-structured interviews with real estate companies, architecture companies, one consulting company and one interest group.   Existing challenges regarding implementation of BIM among different stakeholders, which may be the basis for impaired interoperability, can be explained in the absence of common industry standards, absence of a central BIM coordinator and generally low level of education about the subject BIM. It is noted that there is an information gap between stakeholders working on the administrative side versus design/construction and can be partly explained due to reluctance to adapt to new solutions according to innovation theory and partly due to the absence of common industry standards. The fact that the cost so far is not always less than the benefit of investing in BIM may explain why stakeholders in the project phase choose that BIM does not have to be appropriate to implement.    The implementation phase through the value chain of a project varies a lot for different stakeholders and because of that the industry may in some cases be interpreted as conservative. This could be explained due to the language barriers that can arise when using different BIM systems and due to absence of open standards. To further develop understanding on the subject issue, studies need to be carried out on proprietary rights and problems in tender calculation estimates. Moreover, studies on public sector impact regarding development around common industry standards, external and internal BIM coordination linked to more effective project management and how common industry standards affect different stakeholders in the whole value chain of a project may develop understanding on the subject issue.

The Value of Data Regarding Traceable Attributes in a New Era of Agriculture : Bridging the Information Gap Between Consumers and Producers of Organic Meat

Kransell, Martin January 2014 (has links)
Purpose – This study aims to explore, and suggest solutions to, the gap between the supply of information from organic meat producers and the demand of information from consumers regarding traceable characteristics (attributes) of meat in a limited geographical area in order to maximize the utilization and value of collected data. Design/methodology/approach – A mixed methods research design is applied to collect both quantitative data from consumers and qualitative data from suppliers to produce empirical results of the supply and demand of information. A theoretical framework of organic food purchase intent is used for the quantitative study as well as the correlation between consumers’ perceived importance of attributes and their willingness-to-pay for meat. The results of the empirical studies are compared to each other in an effort to expose a possible gap using a gap analysis. Findings – Meat is shifting from a price based commodity to a product based on characteristics. This study reveals that there is now a gap between the information made available by organic meat producers and the demand of information from consumers that needs to be recognized in order to maximize the value of collected data. Information regarding environmental impact of raising and transporting the animals is not extensively collected. A substantial amount of data about attributes of perceived importance, such as safety and handling, animal welfare and medication or other treatments is collected but not extensively shared with consumers. Research limitations/implications – The small sample size in a unique area and the scope of the survey data does not provide a result that can be truly generalized. It is therefore suggested that future studies produce results from a larger sample that incorporates the perceived accessibility of important information for consumers. Practical implications – This contributes to the emerging literature of organic food production by comparing both the supply and the demand of information regarding attributes of meat. This information is valuable to organic meat producers and marketers as well as developers of agricultural systems and databases that should shift their focus to consumer oriented traceability systems. Originality/value – This study goes beyond the substantial body of literature regarding attributes of organic food and consumers preferences by comparing these factors to the available supply of information by meat producers and by suggesting solutions to bridge the gap between them. Keywords – Organic meat, Organic agriculture, e-Agriculture, Traceability, Traceability systems, Consumer oriented, Consumer behavior, Willingness-to-pay, Supply and demand, Information gap, Gap analysis, Business development, United States of America, Sense-making theory, Mixed methods Paper type – Research paper, Bachelor’s thesis
