Item CHALLENGES OF TECHNOLOGY TRANSFER IN CONSTRUCTION INDUSTRY: THE CASE OF PREFABRICATED ELEMENTS IN BUILDING CONSTRUCTION IN ADDIS ABABA CITY(Hawassa University, 2021-04-27) ASGELE KIDU GEBREHIWOTMany construction innovations incorporate technologies that have been transferred from one geographical area or discipline to another for the facing numerous difficulties in the industry. Technology Transfer (TT) is in the interest of many developing countries; however it is not pacing forward as its target. Many of developing countries set policy to transfer prefabricated construction technique, yet there was a problem on its succeeding. Technology transfer initiatives can be instrumental in solving a lot of challenges in building construction. Dynamic change is needed today to overcome new challenges in the construction industry. Adoption of prefabrication is one of the possible solutions to such problems. This paper assessed the challenges of transferring and expansion of prefabricated building construction techniques through both qualitative and quantitative research method. Besides, this study aims to evaluate the current status of prefabrication building transferring and adoption in Ethiopia and, identified the best channels of transferring and expanding the technology. An extensive literature review was conducted on this subject towards the understanding of TT and prefabricated building construction in developing countries. And, a set of questionnaire and semi-structured interview was used to collect the data. As well as two case studies was conducted. Mean index and RII method using SPSS, and Excel has been used to analyze the results. On this study the practice of prefabricated building technology in Ethiopia shows almost to non-existence. As numerous challenging factors are impeding the adoption, and development of prefabricated technology in developing countries. The result shows, limited awareness and trust on the technology and shortage of initial funds are the most challenging factors in transferring and expanding of prefabricated building technology in Ethiopia. Shortage of infrastructure is also one of the critical obstacle in expanding the technology. Furthermore, as the succeeding of adopting and developing of one technology was measure through the mechanism used to adapt and improve the technology. Hence the study shows trainings was the best way to transfer and sustain prefabricated technology. As well as sub-contracting was the second best way in transferring and sustaining the technology. Other critical channel to improve the technology was working in research and development.Item KNOWLEDGE MANAGEMENT PRACTICES IN CONSTRUCTION COMPANIES: THE CASE OF HAWASSA CITY(Hawassa Unversity, 2021-10-16) TEMESGEN ELIAS OLOLOKnowledge management is a process that transforms individual knowledge into organizational knowledge. The research aimed at assessing the practice of knowledge management, investigate barriers in implementing the system, develop a framework to efficiently practice KM in construction companies of Hawassa city. Although KM is a relatively new and emerging discipline, it has shown its value and promise in existing applications in the construction industry. A holistic KM framework was developed to set the overall context for managing knowledge in construction companies by outlining the main aims and outcomes of managing knowledge, the key knowledge activities, effective KM strategies and instruments, and KM enablers. The sampling frame considered for the study included stakeholders like contractors, consultants, and professional associations. Primary data is obtained from four case studies and questionnaires and interviews conducted from different stakeholders of the construction projects in Hawassa. After that findings are carried out from collected data analysis. Using the result of the analysis found, recommendations and conclusions were drawn. As this study is empirical, secondary data is obtained from reference books and related documents through a literature review. A triangulation of questionnaire survey, semi-structured interviews, and case studies were employed in this research to collect required qualitative and quantitative data. Therefore, the study reveals the shortcomings of the current KM components practices in these selected construction companies for their better efficiency and success of projects. The small level of awareness and acceptance of the concept and practice of knowledge management by the professionals of these construction companies is regarded as a prospect by this research. Besides, owing to the lack of an overall knowledge management policy or strategy, different organizations pursue the practice of knowledge management factors in their way, with some of them barely making use of the knowledge management component system portal. This situation calls for organizational efforts to reinforce the practice of knowledge management by formulating comprehensive knowledge management policy/strategy compatible with organizational strategy, enhance the level of employee awareness regarding the concepts and benefits of knowledge management, implement formal knowledge management means that improves company’s performance
