Currently we could define two groups of work methodologies in project development: the traditional and the BIM-based. In the traditional methodology, engineering or construction projects are developed with departments that work in parallel and independently. The BIM methodology allows working simultaneously on the same project. In this case the operation for the development of the same one is interdisciplinary and all the departments collaborate from the beginning in the development of the asset.
Benefits of BIM in the reduction of costs and times
Working with BIM methodologies allows for faster and more accurate real-time information on teams and budgets. BIM improves communication, reduces waiting times to obtain information and reduces interference that leads to problems during the different phases of the project, thus reducing the costs associated with this type of incident.
The collaboration of the different departments allows to reduce interferences between disciplines that derive in problems during the different phases of the project.
The MacLeamy curve
The MacLeamy curve represents in a very clear graphic way the effects of the use of BIM on the evolution and costs of the project. Curve 3 shows the effort required in traditional design from the conceptual stage (PD) to the construction stage (CD). Line 2 shows the cost as the project progresses. Curve 4 represents the effort in BIM.
It can be seen that in the early stages of the project the cost is higher, but it is reduced efficiently throughout the other phases of the project until its final stage.
