| dc.description.abstract | Construction projects in Ethiopia's building industry frequently suffer from schedule delays, cost overruns, and rework resulting from poor interdisciplinary design coordination. This study comparatively analyzes Building Information Modeling (BIM) and traditional Computer-Aided Design (CAD) as project management tools, with particular focus on their effects on design coordination efficiency and schedule performance., using the Republican Guard Headquarters Project at Ovid Kling Consult as a case study. A mixed-methods approach was adopted, combining a semi-structured questionnaire distributed to 58 project professionals, of which 53 valid responses were returned through purposive sampling, with case study analysis of project schedule records and clash detection data. Descriptive statistics and thematic analysis were used to analyze the collected data. The findings reveal that Design coordination using traditional Computer-Aided Design (CAD)-based approach was found to be manual and mostly reactive. Conflicts were detected at late stages of the project and this required multiple design revision cycles with rework and cascading schedule delays across multiple work packages. In contrast, BIM-based design coordination detected and resolved design conflicts at the conceptual design stage with a reduction of 66.7% of design revision cycles. The tool also contributed to improved schedule adherence, reduced rework and enhanced communication between disciplines. Likert scale results confirmed strong professional consensus on Building Information Modeling's superiority across all five project management performance dimensions assessed. The case study further validated that digital modeling improved the accuracy and efficiency of design coordination. In addition, this study identified a number of barriers that exist for the adoption of BIM, including the skills gap, high cost of BIM implementation and resistance to change. Training and investment in BIM software and processes are recommended in order to improve the performance of design coordination in the AEC sector. | |
