Implementation of BIM aproach for the design of high and extra high voltage electrical substations

This article presents BIM tactics, implemented in the modeling of 3D objects for high and extra high voltage electrical substations, useful to reduce the time involved in making a change, as well as to evaluate various scenarios and their implications by providing 3D and 2D information that feeds decision making. It is based on three fundamental substation design processes that have a high impact on the projects, such as the creation of a digital twin from existing information in the field, modeling a surface for setting out the earthwork construction plan, and creating reusable parametric “families” (groups of object types), non-native in Revit® software, such as drains, trenches, ducts and reinforcement in foundations, all this applying modeling process design to determine the path that allows the greatest optimization of the resources; finally the project presents a link between all the objects that are part of the BIM3D model.
