Compared to the traditional method, the adoption of BIM creates both many-opportunities and-challenges too. BIM technology provides a project from the outset, a-greater control and precision to project members, they can-manage-more efficiently some variables like cost, quality and time. These kinds of benefits have a major influence on both-productivity and production efficiency in addition to every-activity related to information management. As a result, the design of information is explicit and available to all stakeholders who are then able to support decision-making initiatives through better management, use and sharing of information. In the first moments of the rise of BIM, project participants-were used to using their own tools and systems to share information that were structured and suitable for their specialized needs and requests. For this reason, the amount of information that could be distributed was limited due to the lack of a central source of information. The issue has now come to an end, because today the project data is-reachable through different BIM software that controls information of a project more-efficiently.
Previous case studies show that the use of BIM can lead to monetary savings by reducing the cost of retrieving project information in minimizing life cycle costs of the facility. The return on investment from BIM implementation-was analysed by Young, who found out that approximately:

The article will now follow with an analysis of the benefits at the different phases of the lifecycle of a project. These are divided into 3 principal phases: pre-construction, construction and post construction.
Pre - Construction Stage
Post - Construction Stage
Advantage of BIM
The CIFE (Centre for Integrated Facilities Engineering) of Stanford University run a survey on 32 big projects that use BIM and identified the advantages. Among those:
