    Developing BIM-Enabled Built Asset Facility Information Management System: A Case of Public Universities In Addis Ababa
    (Addis Ababa University, 2022-06-01) Tamiru Mengst Habtu; Asregedew Kassa Woldesenbet
    Facilities management (FM) is a discipline comprising various processes, activities and maintenance services to support the main functions of built asset facilities. It demands sets of comprehensive information. Lack of information is one of the major challenges in the O & M phase of the built asset. The emergence of Building Information Modelling (BIM) systems, helped to solve the issue and improve the efficiency of built asset facilities management. Currently, the public universities have no data/information and related documents on the built asset facilities. The built asset facilities information management system is conventional and has a major difficulty. Therefore, it is necessary to study BIM Enabled Built Asset Facility Information Management System. This study aims to explore the current practice of built asset facility information management systems in public universities and identify the required information for BIM-enabled built asset management. The importance of identifying the required information is to facilitate the FM decision-making process. Finally, this study aims to develop the conceptual framework of a BIM-enabled built asset facilities information management system. The study adopted both descriptive and exploratory types of research. A multiple-case study was conducted on the three public universities in Addis Ababa. Data collection and analysis were based on an extensive literature review of similar studies followed by a semi structured interview, document analysis, and observation. The study adopted both quantitative and qualitative methods. All interview, document analysis, and observation data were analyzed using the thematic and statistical analysis method. The study findings indicated that the FM office in public universities didn’t have the data or information of the old built asset facilities but to some extent, they have as-built drawings for recently completed projects. So, the lack of information has an impact on the time and the cost of the O & M process of the built asset. The FM office practiced the conventional method to capture, visualize, transfer and manage the built asset information. Currently, all the basic, technical, managerial, commercial, financial, and legal information are extremely relevant for built asset management in the selected public universities. Accordingly, to manage the built asset information, the FM office in public universities needs a single platform. As a result, a BIM-enabled FM conceptual framework was proposed. Finally, the future study should further develop the proposed framework and adopt it in public universities.

    Developing Built-Asset Maintenance Maturity Rating Model for Public University Buildings in Ethiopia
    (Addis Ababa University, 2022-06-01) Zewdu Seblework Tafesse; Asregedew Kassa Woldesenbet
    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.
