of software for automated formation of cost estimate documents based on BIM models

Introduction. The construction industry is rapidly transitioning from traditional computer-aided design (CAD) to building information modeling (BIM), which allows for detailed modeling with real accuracy. BIM specifies not only the geometry of an object, but also its materials and characteristics. Construction projects created using BIM technologies can automate cost estimates, significantly improving accuracy and reducing time expenditures. However, cost estimation specialists have not yet been fully integrated into BIM processes.

Aim. The article aims to determine the feasibility of using software to automatically generate cost estimation documents from BIM models and identify the pros and cons of using it in the operations of a construction organization.

Materials and methods. An analysis was conducted of the software market offering automated cost estimation based on digital models. Selected programs were tested, and relevant publications by other researchers were examined.

Results. The software packages BIM-smeta ABC, 5D-smeta, BIM WIZARD, and Larix were evaluated. BIM-smeta ABC is user-friendly, but it operates directly within the model, which may compromise its integrity. 5D-smeta and BIM WIZARD allow designers and cost estimators to work in separate spaces, preventing estimators from directly manipulating the model. Additionally, BIM WIZARD offers 3D visualization capabilities for cost estimators. Larix enables automated calculations based on predefined logical sequences, which makes the initial setup process more labor-intensive for company-specific needs.

Conclusions. Automating cost estimation in BIM modeling provides the greatest benefits to companies that strictly adhere to internal design standards, especially the Employer's Information Requirements (EIR) and the BIM Execution Plan (BEP). In such organizations, the estimation process can be reduced to just minutes. Conversely, companies lacking such standardized design systems may require significant time and resource investment for implementation.
