The initial cost of BIM can be significant due to the required investment in software, technology infrastructure, consultants and training. Organizations also incur project-specific costs for customizing BIM models and changing workflows and team processes. However, companies wishing to evaluate the financial benefits of BIM often find limited information. This lack of detailed cost-benefit analysis may lead to some decisions being made against investment. Figures 2 and 3 show that BIM leads to a change in the allocation of resources and costs associated with the early stages of a project. Compared to the traditional 3D CAD with BIM approach, BIM is considered to be more efficient and less time consuming, so it is cheaper.
