The quantity survey of the route occurs according to Gauß-Elling (REB 21.003). Individual traces or the whole location can be considered, depending on your selection. Additionally there is the possibility to conduct the calculation step-by-step, this means only between two defined stations. The results are recorded in a separate file (PDF, XLS or ASCII). The program draws profiles of masses in the location plan, which can be used for the plot afterwards. The calculation generates for the data exchange the DA66, respectively DA51, DA53 and DA54.
The quantity survey according to Elling isn't necessary for each project. Often the mass is determined over the surfaces between the single surveyings (before and after the building phases). Especially the 3D-quantity survey offers a suitable solution for this requirement: the individual surfaces of the route are determined and multiplied with the particular profile structures. The result are volums sub-divided to traces. Optionally the program induces 3D-solids of the whole location. Generally this calculation method serves as a plausibility check.
The user can generate pavement height- and pegging plans in the pavement design specification. The output of the height can be regulated individually for every trace. There is the possibility to conduct the calculation for a defined area, as well as with quantity survey. Formation level books, as well as point files for building machinery, can be executed also. The program represents the pavement heights as absolute height, as differential height to the alignment or as differential height to the terrain. Thereby the software stores the textpositions. The user writes a measuring point file for the import in the surveying instrument, in doing so the coding is defined as user-related. The calculation generates the data type DA45 for the data exchange.
During the detection of the embankment and the terrain model of the route the information off the vertical alignment, off the slopes and the width of borders and off the embankment inclinations is considered. The embankment edges are illustrated as separate polylines in the location plan, they can be used and edited again. The software generates automatically embankment arrows, hatch patterns, colors the filling and excavated areas differently and files all results on separate layers. The new surface net delivers (blended with the ancestral terrain) the base for realistic views. BBSoft® includes manholes and reaches automatically in the 3D-model. The heights of the covers correspond to the actual height of the pavement.
