Impact of information included in the BIM on preparation of Bill of Quantities

The article present the potential of using the BIM technology in the process of bills of quantities preparation for construction works. The article show the role of information collected in the model. The information entered into model and collected in the model during the design phase has a big impact on Bill of Quantities. The more detailed the information in the BIM model and as a result the more detailed description of the works in the BoQ make a cost calculation more accurate. As an example the paper presents the process of feeding information to the model based on selected construction works design software. Then, the paper presents the process of entering information on construction works and elements and the impact of entered information on bill of quantities on examples of earthworks, foundations and wall construction.
