Increasingly, enterprises are enhancing cost control and profitability by adopting BIM technology. From a detailed perspective, the advantages of BIM in cost management are mainly reflected in the following areas:
1. Accurate Data Processing: Currently, China lacks a unified standard for measuring engineering quantities, and deduction methods for overlapping structural components vary by local regulations. Manual calculation and summarization of these quantities have traditionally been tedious and error-prone. BIM, based on parameterized models, utilizes spatial topology and 3D calculation rules. When calculating quantities, the software only requires replacing the relevant deduction rules, then autonomously executes the calculation process, producing precise and comprehensive quantity data.
2. Resource Planning: Traditional cost control depends heavily on engineering experience for resource allocation and scheduling. However, as construction projects grow in duration and complexity, relying solely on past experience becomes insufficient. This can lead to delays and slow progress, risking quality and safety. BIM technology integrates time and cost data, enabling dynamic monitoring and optimized scheduling to meet modern project demands.
3. Handling Changes and Claims: Previously, managing design changes or contract claims involved identifying component changes on floor plans and manually calculating the resulting quantity variations in surrounding components—a process that is time-consuming and often unreliable. With BIM, adjustments are made directly within the model, and the software automatically calculates and summarizes these changes, making the process faster, more accurate, and more reasonable.
4. Multi-Calculation Comparison: Traditional measurement models focus mainly on contract price and settlement price. BIM maps parameter data to each component and integrates information across components, facilitating multi-faceted calculation comparisons for construction projects.
