Abstract: As BIM methodology has been mostly implemented in the construction industry, certain areas such as surface mining have been neglected. Mining projects are generally large and often located in hilly landforms; consequently, critical activities included in the construction schedule may have a high risk and cost impact.

The aim of this research is to implement BIM in a mining project for collaborative works through 3D, 4D and 5D modeling to ensure the adoption of the best work practices in project planning, improving constructability and reducing risks, as well as to achieve an adequate cost control during the development of the project. Regarding planning, a detailed description of the division of the activities to ensure continuous operation and the sectioning of the project, considering the hilly topography of the area, is provided. The work method for project modeling is also explained and the issues found at this stage are presented. Based on the results significant benefits were achieved using 5D modeling, including a better visualization of the design, thus ensuring appropriate constructability and cost control.
