    Functions at a Glance

    Drainage Planning for Parking Areas and Traffic Facilities

    BBSoft® civil engineering software for surface drainage enables precise planning of drainage systems for parking areas, roads, and traffic facilities. In compliance with RAS-EW, the software supports parking area drainage, road drainage, and surface planning in civil engineering. Automatic slope adjustment, integrated plausibility checks, and direct integration with the digital terrain model (DTM) ensure reliable results within the CAD location plan.

    Drainage Planning

    Plan surface drainage in a CAD-based environment – with rapid design, automatic slope adjustment, and plausibility checks.

    Parking Area Drainage

    Parking drainage software: plan slopes, surfaces, and drainage directions for parking areas in front of supermarkets, company premises, and roundabouts.

    Road Drainage

    Road drainage in accordance with RAS-EW: calculate catchment areas, automatically place road inlets, and connect them to the existing sewer network.

    Reliable Results

    Thanks to direct integration with the digital terrain model (DTM) – including data exchange via LandXML and DA58, plausibility checks, and subsequent editing.

    Drainage planning with BBSoft® – CAD-based and aligned with current planning guidelines. Surface drainage systems can be designed quickly and efficiently, even without predefined slopes or elevation data. When adjustments are made later, the software automatically responds with slope adjustments, ensuring the planning remains consistent at all times. Additionally, slopes that are too low or too steep are highlighted directly using color markings, allowing planning errors to be identified and avoided at an early stage. Automatic slope adjustment – changes at the starting point update all measured points accordingly.

    • Color-coded highlighting of tolerance deviations for slopes that are too low or too steep
    • Planning of closed systems for complete drainage concepts
    • Direct display of drainage direction within the drawing
    • Creation along predefined or newly defined contours
    • Multiple editing of surface drainage objects for efficient adjustments
    • Repair of faulty line connections within surface drainage
    • Export and import of drainage paths between projects
    • Definition of a uniform dependency direction or slope along a drainage path
    • Plausibility check of created surface drainage objects

    The parking drainage and parking planning modules of BBSoft® enable precise design of parking areas, roundabouts, and intersections, including drainage and stormwater management. Slopes, drainage areas, and drainage directions are planned in a CAD-based environment – for parking areas at supermarkets, company premises, schools, and public facilities. DTM calculation based on existing survey points and breaklines ensures a realistic representation of the terrain.

    • Parking drainage software – plan slopes and drainage areas for parking facilities
    • Parking planning software: roundabouts, intersections, and parking areas
    • Drainage for parking areas at supermarkets, company premises, and public facilities
    • DTM calculation based on existing survey points and breaklines
    • Definition of target distances for slopes and reference DTM
    • Elevation adjustment of generated survey points to an existing DTM
    • Insertion of additional support points into existing drainage connections
    • Automatic slope adjustment for all connected surfaces and survey points
    • Drainage direction displayed directly within the drawing

    Road drainage in accordance with RAS-EW – BBSoft® calculates catchment areas, determines the number of road inlets based on the drainage area and a predefined intake capacity, and places them automatically within the location plan. Road inlets can be connected to an existing sewer network, repositioned, or extended at a later stage – ensuring a complete and traffic-safe road drainage design.

    • Road drainage in accordance with RAS-EW – calculation based on established drainage guidelines
    • Calculate and evaluate catchment areas – visually clear representation in the location plan
    • Automatic calculation and placement of road inlets within the location plan
    • Intake capacity can be defined freely – partial areas are aggregated and considered
    • Connect road inlets to an existing sewer network
    • Output of road inlets with corresponding coordinates
    • Clear listing of drainage low points, marked within the location plan
    • Indication of which side of the alignment is drained
    • Marking in the location plan for longitudinal slopes below 0.5%
    • Flow arrows can be displayed for visual verification
    • Road inlets can be added, moved to another station, or deleted at a later stage
