Cost Estimation And Cost Control of Construction Project Using BIM Technology

The integration of Building Information Modeling (BIM) into cost estimation and control represents a transformative shift in construction management. Unlike conventional methods, BIM enhances accuracy, transparency, and efficiency through real-time data integration, 3D visualization, and automated clash detection. This study highlights how BIM significantly reduced project costs by 9.06%, lowering the planned expenditure of ₹1,221,432,472 to an actual cost of ₹1,110,727,461. The savings of ₹110,705,011 were primarily achieved through precise estimation, streamlined material management, and reduction of rework, particularly in high-cost components such as RCC and site setup. By minimizing design errors, improving collaboration, and enhancing decision-making, BIM establishes itself as more than a design tool—it is a cost-optimization strategy that ensures financial discipline, operational efficiency, and long-term sustainability in construction projects. The findings confirm BIM’s essential role in modern, cost-conscious project delivery by strengthening budget reliability, reducing risks, and maintaining quality within planned timelines.
