    Application Of 4D/5D Bim in Construction Project Management: The Case of Selected Building Projects in Addis Ababa
    (Addis Ababa University, 2025-05) Eyerusalem Melese; Abraham Assefa (PhD)
    This thesis investigates the application of 4D and 5D Building Information Modeling (BIM) in construction project management, focusing on selected building projects in Addis Ababa. It addresses challenges faced by the Ethiopian construction industry, including low productivity, inadequate schedule control, and ineffective cost management due to traditional project management methods. The study begins with a comprehensive literature review outlining the theoretical framework of construction project management and the limitations of conventional practices. It emphasizes how technological advancements, particularly BIM, can significantly enhance project outcomes through improved visualization, coordination, scheduling, and cost estimation. A developed 4D/5D BIM framework is applied to three projects: the New Ethiopian National Theatre (Project A), Addis Capital Goods Mixed-Use Building (Project B), and Ethiopian Petroleum Station Mixed-Use Building (Project C). The research highlights how the framework integrates 3D modeling with time (4D) and cost (5D) dimensions to boost project efficiency, accuracy, and transparency. Key BIM objectives identified include improving design quality, transitioning from conventional designs to integrated BIM workflows, ensuring quality control, and facilitating effective stakeholder communication. By utilizing advanced BIM tools like BEXEL Manager, the study demonstrates the benefits of automated processes such as clash detection, quantity takeoff, cost estimation, and progress monitoring. For Project A, the implementation of a federated BIM model resulted in significant advancements in collaboration, data management, and construction planning. However, challenges were noted in Projects B and C, including incomplete mechanical systems, undefined model elements, and inconsistencies in work planes. These issues were attributed to deviations from ISO 19650 standards, Ethiopian Standard ES and the lack of critical documents like the BIM Execution Plan (BEP) and Employer’s Information Requirements (EIR). The findings indicate that while the projects reached basic BIM maturity (Level 2), substantial gaps remain in achieving higher levels of integration and optimization. Limitations include a shortage of skilled personnel, incomplete data for 4D/5D processes, and reliance on generic models. To address these gaps, the study emphasizes the need for adherence to ISO 19650 standards, the development of robust BEP and EIR documents, and targeted training programs for stakeholders. The research concludes with a roadmap for improving BIM maturity, transitioning from basic 3D modeling to fully integrated 4D/5D workflows. By addressing identified gaps, the Ethiopian construction industry can fully realize BIM’s potential, thereby setting a benchmark for large-scale public infrastructure projects. This study contributes to the knowledge on BIM implementation, offering practical insights and recommendations for advancing BIM adoption in resource-constrained environments.

    Effect of E-Banking Service Quality on Customer Satisfaction: The Case of Nib International Bank S.C. In Addis Ababa
    (A.A.U, 2026-02-01) Eyerusalem Melese; Abera Legesse
    The primary objective of the study was to examine the effect of E-banking service quality on customer satisfaction at NIB International Bank S.C. in Addis Ababa. This research is highly relevant to stakeholders in the banking and financial services sector, as it offers practical insights into leveraging E-banking innovations to enhance customer satisfaction and maintain a competitive edge in a rapidly digitizing financial environment. A quantitative research approach with an explanatory research design was employed and data were collected from 390 E-banking user using structure questionnaires aligned with the study objectives and relevant literature. Statistical tools like explanatory correlation techniques and multiple regression analysis were used in data analysis. The finding indicated that all e-banking service dimensions recorded mean scores above the midpoint indicating generally positive customer perceptions. Customer satisfaction was positively and significantly impacted by responsiveness customer support security innovation and user interface according to correlation and regression analyses however ease of use despite its high rating did not have a statistically significant impact. The strength of the identified predictors was highlighted by the regression model which accounts for 72.8% of variance in customer satisfaction. The study concluded that while NIB International Bank had made significant strides in implementing digital banking channels more advancement in customer service, user interface design, IT infrastructure customer support mechanism, platforms efficiency, and cyber security measures were essential to enhance overall customer satisfaction
