BIM (Building Information Modeling) is a comprehensive, efficient solution that covers the entire construction process. It serves not only as a design tool but also supports implementation and operational maintenance phases. By using BIM, information flows seamlessly across all project stages, ensuring smooth communication and coordination throughout the project lifecycle. For developers and real estate companies, the primary focus is on investment efficiency—maximizing returns while minimizing costs.
For developers, managing investment risks is crucial, with return on investment being a top priority. BIM technology enhances design optimization, visual management, and scheduling, providing cost estimators with accurate project quantity data and encouraging new perspectives. In real-world projects, BIM changes the sequence of cost expenditures and improves forecasting accuracy, which is invaluable for effective risk management.
During project execution, design plays a foundational role. If issues arise during construction, adjustments or complete redesigns are often needed, leading to significant waste. In China’s construction industry, such waste can exceed 50%. The real estate sector faces similar challenges due to diverse user requirements and complex product designs. Problems detected mid-construction often result in redesigns and rework, exacerbating waste. Common cost control challenges include large budget discrepancies, frequent changes, and difficulties coordinating multiple disciplines and processes.
Implementing BIM technology can address these issues effectively: it can eliminate up to 40% of unplanned changes, reduce budget preparation time by 80%, and maintain budget accuracy within 3%. This leads to savings of around 10% of the contract value and reduces project duration by approximately 7%, making BIM an essential tool for cost control in real estate development.
