| Abstract: |
The application of Building Information Modeling (BIM) has fundamentally transformed the way multi-story buildings are designed, coordinated, and analyzed across the global Architecture, Engineering, and Construction (AEC) industry. This empirical study presents a comprehensive BIM-based framework developed and validated through its application on five real-world multi-story building projects ranging from G+4 residential structures to G+22 high-rise complexes. The framework integrates BIM Level 2 and Level 3 maturity tools to address critical challenges in structural coordination, MEP (Mechanical, Electrical, and Plumbing) clash detection, cost estimation accuracy, and project schedule adherence. Data were collected from 85 respondents including architects, structural engineers, MEP consultants, project managers, and contractors, supplemented by quantitative project performance records across all case study sites. Findings reveal that BIM Level 3 implementation achieved clash detection accuracy of up to 94.8%, reduced cost variance to as low as 3.2%, and decreased Requests for Information (RFIs) by up to 71.2% compared to conventional design workflows. MEP coordination using BIM led to an 85.2% overall reduction in pre-construction clashes, translating to a combined cost saving of USD 127,100 across a representative project. Statistical analysis confirms significant improvements in structural redundancy, load path efficiency, and material optimization when BIM is integrated at the design stage. These results substantiate the efficacy of the proposed framework and its scalability for high-density urban construction environments. The study contributes an evidence-based, replicable BIM deployment model that aligns with international standards including IFC, ISO 19650, and LOD 300–400 specifications, offering actionable guidance for practitioners and policy-makers in the construction domain. |
