There are two main approaches to cost modeling:
The first approach involves expanding the dimensions of BIM by integrating a cost function module. This allows costs to be generated directly within the BIM environment. Since BIM and cost are closely linked, any changes in the model will update the associated costs, and vice versa.
The second approach separates the cost module from the BIM model. In this case, project information is extracted from the BIM model and imported into cost estimation software, or a data link is established between the BIM and cost software.
It is important to understand that cost is a dynamic concept. It remains static only when both quantity and price information are unchanged. In reality, cost is constantly fluctuating, making this static state rare.
