How should cost personnel integrate BIM with cost management software? When designers create BIM models, they often focus solely on design and owner requirements, neglecting the specific needs of cost management. They typically include only design-related information in the BIM models, without considering the data necessary for cost control. However, this does not mean that BIM models are useless for cost professionals—they still hold significant value for cost management purposes. There are two main approaches for cost personnel to manage costs using BIM models:
First, they can add specialized cost management information to the BIM model provided by the designer.
Second, they can extract existing project data from the BIM model or establish links between the model and existing cost management systems.
The first approach is highly integrated, offering the advantage of closely combining design and cost information. Any design changes automatically update the cost estimates, and cost adjustments can be reflected back into the design model. However, this method has some drawbacks. BIM models tend to become very large, which can strain hardware capabilities. Additionally, it requires strong collaboration among design, construction, cost, and other stakeholders, making implementation more complex.
The second approach is a looser integration. It is relatively easier to implement from a software perspective, but the connection between design and cost data is weak. Design changes do not automatically affect cost calculations, and cost updates do not influence design modifications, often requiring repeated manual operations.
Integration between BIM and cost software can be achieved through several methods:
1. API (Application Programming Interface): BIM software offers APIs that allow third-party applications to access BIM model data. This enables integration with cost software and also supports reverse operations, transferring data from cost management systems back into BIM.
2. ODBC (Open Database Connectivity): ODBC is a database access technology that facilitates the integration of exported data with various applications. However, changes in the database and the BIM model cannot be synchronized automatically, requiring manual intervention.
3. IFC Standard Data Format: The IFC (Industry Foundation Classes) standard provides a universal data format for BIM models, promoting interoperability. While its widespread adoption is an advantage, the efficiency of data exchange using IFC can be lower compared to proprietary formats.
