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 Importance of Labour Union for Improving Labour Productivity in Construction Projects; in Ethiopia Case of Omo Kuraz Sugar Factor(Hawassa University, 2018-10-29) Tsion Arega AdimassuConstruction sector need high involvement of labour workers. Fulfilling sufficient amount of qualified labour workers in appropriate time is very important for the efficiency of the sector. In other side, keeping the right of labour workers in over all respect is very important. To familiarize both the demand of labour workers in construction sector and assure the right and responsibility of labour workers, collecting labour workers in organization is one of the ways. Its main objective is assessing importance of labour workers union in improving labour productivity and completion of construction projects with in specific cost, time and quality. The study was conducted by using mainly quantitative method supplemented by qualitative study method. The research design is based on a purposive sampling selection process in terms of which a representative sample of stakeholders/participants in the construction process will be surveyed. Interviews, questioners and observations are data collection tools of this research. The data were also cleaned and checked for completeness and exported to SPSS 16.0 soft ware for analysis. As the finding show around 92.7% of the projects have no first aid clinic. Only 17.1% of the workers wear PPE. As stated in this finding, only 24.4% of workers have taken qualification measurement during employment. In case of work place condition only 9.8% of workers got training during or before working time, only 7.3%of the total projects covered in research area are got workers near project site so that there is high loss of time in mobilizing and employing. Finally the research states, all mentioned problems highly affect construction projects. Lack of qualification measurement, lack of training, unsafe working condition, time loss on mobilization of workers are major problems observed on the research which can highly affect construction projects cost, quality and time. Finally the research states that labour workers union are important on improving efficiency of construction projects so that, employers, labour workers and all concerning bodies Encouragement and support of formation of union are needed. This research contribution is mainly on identify the use of labour workers union in keeping quality, minimizing cost ,and completing project with specific time in building construction projectsItem 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
