    Design Management Practices in Building Design Process in the Case of Ethiopian Construction Consultant and Design Engineers
    (Addis Ababa University, 2022-08-01) Samson Melesse Mamo; Tadesse Ayalew (PhD)
    In recent times, the construction industry has been under pressure to improve efficiency in terms of quality improvement, timely delivery, and maintaining budget costs. The need for quality design solutions and effective processes has also incited significant emphasis in the industry. This study aimed to assess the design management practice in the building design process for Ethiopian construction consultants and design engineers in Addis Ababa. Accordingly, the study employed a quantitative research design. The study mainly used primary sources of data to collect the necessary information. It used three data collection methods, namely a questionnaire, an interview, and a document review. By employing descriptive statistics, this study found that challenges of design management practice included a lack of a structured and explicit design process and design information production and flow, as well as unimproved design planning, lack of design management tools and techniques and implementation by an inexperienced team. It mostly exhibited unsatisfactory level of design management disciplines, and various barriers included tools poorly deployed into industry practice, deficient resources in quality or quantity, and the inability to have a design checking system. There are also difficulties areas in terms of improvement needs on better managing design process include of having adequate design time increasing specialized design professions, to recognize design is as a process. Thus, the study concluded that these organizations created a low-level design management practice definition that involves setting high-level project milestones or gateways that the team can work towards. Accordingly, this study suggests that organizations must be cultured about the importance of the design process in delivering value to the whole project, how the way they work affects the design process, how they can contribute to the design and consequentially the whole project process. Therefore, implementation of a design management tool or practice must include and educate at all levels within an organizations and project team to ensure it is taken up in practice.

    Developing Built-Asset Maintenance Maturity Rating Model for Public University Buildings In Ethiopia
    (Addis Ababa University, 2022-06-01) Zewdu Seblework Tafesse; Tadesse Ayalew (PhD)
    In Ethiopia, a significant amount of funds is invested in mega projects like dams, highways, railways, airports, power plants, public buildings, etc. These investments are showing unprecedented expansion which, by some estimates, has shown a 9-fold growth of the GDP of the construction sector. However, once these projects, be it mega or otherwise, are completed and ownership is transferred, the post-construction phase of asset management is noticeably neglected, if not ignored totally. And this national reality is witnessed in the building facilities of public universities in the country. In this research paper, a modest attempt is made to examine the building maintenance practice of the nation, factors affecting proper maintenance management, and challenges faced. A thorough investigation of the current situation of building facilities of public universities in Addis Ababa is made. Along with that significant focus is made to develop a viable maturity rating model for building maintenance management of public universities in Ethiopia. A multi-case study was conducted on the three public universities in Addis Ababa. The research approach of this study is both deductive and inductive research. Both quantitative and qualitative data are collected from primary and secondary data sources by document analysis, observation, and semi-structured interviews of the FM office and project office representatives of each public university. All the semi-structured interviews, document analysis, and observation data were analyzed using the thematic and statistical analysis method. The three main objectives of this study are effectively addressed. When it comes to identifying factors that influence the proper practice of building maintenance management in public universities in Ethiopia, the main factors were grouped under seven categories and five critical factors. Finally, a built asset maturity rating model is proposed based on the weights calculated by DEMATEL, MCDM analysis weights that can be used as a self-assessment tool by public universities in Ethiopia.
