My projects have a georeferencing of the original surface, a study of surface drainage, design of terraces, roads, superelevations, intersections, shelters, 3d model with the civil 3d of a corridor with all its streets and avenues where appreciates the intersections, slopes, 3d models of buildings and urbanisms complete with plans and animations. It provides profiles, sections, tables of set out points and calculations of volumes of cut and fill, study of execution that defines the sequence to follow and the type of machine required in a certain area to model the surface. Then, we worked with the 3D construction model in REVIT and defined the complete urbanism model, which presents videos of rendered routes and required plans, cross-sections, vertical and horizontal profiles for roads, sewer line design, curbs and gutters. .etc. If all this makes sense to you, you know what I am looking for
