    Digital planning with foresight

    For the northern expansion of the Breitelen Strangen industrial area, the project was planned entirely digitally from the very beginning. BIT Ingenieure AG, Villingen-Schwenningen office, consistently relied on BBSoft® throughout the project.

    Challenge

    Even before the first excavator arrived on site, a detailed digital model had already been created.

    From the start, the entire project was planned fully digitally – with BBSoft® as the central tool for terrain modelling, traffic areas and utility networks.

    • Creation of a digital terrain model (DTM)
    • Planning of a roundabout including alignments, connections and traffic areas
    • Integration of bus stops and bus bays
    • Planning of water supply and wastewater systems
    • Retention and compensation measures

    This was never just about “a road”, but about a holistic transport concept.

    • Traffic routing for an industrial area, including HGV swept path analysis
    • Safe bus connections
    • Well-designed cycling infrastructure
    • Cross-sections and cycle route alignment
    • Pipe systems and stormwater analyses

    Everything was planned within one continuous digital model: connected, precise and compliant with standards.

    Roundabout planning detail

    Planning detail

    Small details, major impact: bus bays and turning facilities

    A bus arrives, and it immediately becomes clear whether the planning works. Is there enough space for entering and leaving? Are bus stops accessible without barriers? Is the pedestrian crossing safe? Bus bays and turning facilities may appear inconspicuous, but they are essential for practical day-to-day usability.

    Solution

    Planned for practical use and compliance with standards.

    The challenge lies in complying with different regulations and standards such as RASt06, EAÖ2013 and ÖNORM. With BBSoft®, geometries, swept path analyses, crossings and safety clearances can be combined in a way that is both compliant with standards and practical in real-world use.

    This results in solutions that are not only technically correct, but above all suitable for everyday operation.

    Digital planning of the roundabout

    When planning takes shape

    With the start of construction works, digital planning begins to become reality. For the northern expansion of Breitelen Strangen, Walter Straßenbau KG is responsible for the precise execution. Before roads are built or surfaces paved, the crucial work takes place below ground: pipes are installed, manholes are placed and gradients are constructed with precision.

    • Digital terrain models are imported into the machine control systems
    • Alignment data and cross-sections ensure precise height and line guidance
    • Construction site plans and quantity calculations support costing and construction billing

    This is how a digital model becomes precisely built infrastructure.

    Voice from the field

    Professional software. Competent team.

    For Walter Straßenbau KG, BBSoft® is a reliable solution for planning, calculation and documentation in civil and road engineering. The software can be flexibly adapted to different requirements, the modules work together reliably and lead intuitively to the desired result.

    The continuous flow of data is particularly valuable: from planning and calculation through to setting out on the construction site, as well as from field data collection to the as-built plan.

    Result

    Planning becomes infrastructure.

    The new roundabout in the Donaueschingen industrial area is another impressive example of this process: digital planning in BBSoft® coordinates every detail, from alignments and traffic areas to kerbs, utility lines and drainage.

    The current progress on site clearly shows how data, lines and models are transformed into real infrastructure.

    Future-ready commercial areas are planned digitally.

    Whether traffic areas, bus bays, cycle paths, roundabouts or utility systems, modern infrastructure projects are complex integrated systems.

    With BBSoft®, the result is not just roads or networks. It creates connected commercial areas, safe traffic management and precisely executed construction projects.
