    The Impact of the Modern Digital Tool BIM on Client Requirement Management: The Case of High-Rise Building Construction Projects in Addis Ababa
    (Addis Abeba Universty, 2026-11) Lensa Mulugeta; Zegeye Muluye (PhD)
    High-rise building construction projects in Addis Ababa face persistent cost overruns, schedule delays and rework majorly caused by poorly managed client requirement changes. Although Building Information Modeling (BIM) is globally recognized as an effective digital tool for improving requirement management, its adoption in Ethiopia remains limited and its actual impact has not been empirically examined. Therefore, the study aimed to investigate the influence of six BIM parameters: - visualization, communication, information storage, requirement-model connection, assessment and traceability on the effectiveness of client requirement management in high-rise building construction projects in Addis Ababa. The study employed a quantitative research approach using a descriptive and explanatory design. Data were collected from 120 BIM-experienced construction professionals including architects, engineers, quantity surveyors and project managers through structured questionnaires. Purposive sampling was employed and data were analyzed using descriptive statistics, Pearson correlation and multiple linear regression. The findings revealed that all six BIM parameters have a statistically significant and positive effect on client requirement management (R² = 0.799, F = 74.689, p < 0.001). Assessment (β = 0.305) and communication (β = 0.300) emerged as the strongest predictors indicating that they have the greatest direct impact on client requirement management. In conclusion, BIM significantly improves client requirement management by enhancing documentation, communication, evaluation and traceability of requirements throughout the project lifecycle. The findings provide empirical evidence to inform construction professionals, and educational institutions in promoting wider BIM adoption in Ethiopia.
