Terrain data can be read in the form of large point clouds (for example from Scalypso) and displayed graphically. This makes it possible to use high-resolution terrain models as the basis for mass determinations within infrastructure projects.

The processing of geodata enables the recording of property boundaries, flood plains, road networks and much more. With this information, critical zones or points of conflict can be recognised at an early stage and taken into account in project planning. The imported geo-information can also be considered when creating output plans.

For the interdisciplinary exchange of project information, the elements of a road model can be provided with attributes and subdivided into logical road sections. For this purpose, the specifications of the open standard IFC 4.3 from BuildingSmart were implemented for object structuring. By defining attributes, the model can be enriched with essential project and product information. This information can then be made available to all project participants via cloud services.

No project is immune to adapted framework conditions or unforeseeable project changes. With the help of the consistent parametric modelling concept, geometric adaptations can be made at any time and the model updated according to the changed initial conditions. The effort required to adapt the geometric model is minimal and changes are made possible in short time frames.

In Allplan it is easy to extrude freely defined profiles along a line element. This allows, for example, railroad tracks, road dividers, guard rails, support elements, etc. to be placed relative to the axis and consequently also taken into account in the output plans.

Visualisation facilitates cooperation and communication between the project participants. All disciplines can analyse the model together for details, improvements, etc. The visual representation of the road facilitates feedback. Thanks to the excellent visualisation quality within Allplan, structural features can be checked in real time and discrepancies can be resolved quickly.

Creating multiple road axes for optimal line routing is achieved effortlessly. Once an axis has been defined, a rule profile can be assigned to it. The differences between different alignment variants can be quickly recorded and easily compared with each other.

The project area is often surveyed during the execution phase – for example by means of drone flights – and directly compared with the model. Any deviations between the model and the construction situation on site can be quickly detected, validated and, if necessary, adjusted accordingly.

The creation of output drawings is fully automated and always reflects the current model. Depending on requirements, the plan contents can be expanded and adapted as desired.

With the help of reports, parameters of the road model can be output in tabular form. For example, staking points can be created, point distances calculated or bulk and fill volumes determined. The calculation accuracy is freely selectable, and the results can be easily transferred to corresponding programmes for data processing.
