Example: Create concrete geometry and work with pours

The guidelines in this example help you to efficiently model cast-in-place concretecast unit type where the concrete is formed, poured, and cured in its final position

geometries, and to define, visualize, sequence, and report pours and pour breaks.

Before you start, ensure that you have pour management enabled. See Enable pour management.

  1. If possible, use an existing engineering or architectural model or drawing as a basis when you create concrete structures in Tekla Structures.

    Import the existing model or drawing as a reference modelmodel which the designer can use as an aid when building another model

    A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

    For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.

    to your Tekla Structures model.

    See Insert a reference model and Reference models and compatible formats.

  2. If you are using an IFCfile format commonly used in BIM that facilitates software interoperability

    IFC is an open specification developed by the IAI (International Alliance for Interoperability).

    Model can be exported into an IFC file.

    model as a reference model:

    1. Convert the concrete structures you need from the IFC model to native Tekla Structures objects.

      See Convert IFC objects into native Tekla Structures objects and Example: Convert IFC objects into Tekla Structures objects at one go.

    2. Check the conversion results.
    3. If needed, modify the converted objects.

      For example, you may need to change the profile, material, or cast unit typeproperty of a concrete part in a cast unit that defines if the structure type of the part is precast or cast in place

      of the converted objects.


      Use Organizer for checking and selecting objects.

  3. If you are using a different reference model type, or if there are structures that cannot be converted from an IFC model, model the needed concrete structures as cast-in-place concrete parts in Tekla Structures.

    You can model by tracing over the reference model.

    See Create parts and modify part properties.

  4. For each cast-in-place concrete part, define a pour phasepart property that defines which cast-in-place concrete parts form a pour object

    Pour phase can be used to prevent cast-in-place concrete parts from merging into one pour object.

    number to divide your Tekla Structures model into pour objects.

    For example, use the default pour phase 0 for horizontal structures, like beams and slabs, and the default pour phase 1 for vertical structures, like columns and walls, to separate them to different pour objects.

    See Define the pour phase of a part.


    Use selection filters or Organizer to efficiently select multiple parts and to modify them all at the same time.

  5. View and check the pour objects in a pour viewview that displays cast-in-place concrete parts merged into pour objects

    The cast-in-place concrete parts are merged into one pour object if they have the same material grade and if they touch each other.


    See View cast-in-place concrete structures and Pour objects.

  6. If needed, modify the pour phases or create pour breaks to fine-tune the pour objects.

    For example, create pour breaks to split large slabs into smaller pour objects.

    See Create a pour break and Pour breaks.

  7. Once you are ready with the concrete geometry and pour objects, you can define pour sequences by entering pour numbers for pour objects, or by using the Organizer categories.

    See Modify the properties of a pour object and Categories in Organizer.

  8. Calculate the pour units, and modify them by adding and removing objects if needed.

    See Pour units.

  9. You can also define other properties for pour objects and pour units, for example, concrete mixtures, or dates or status of workflow.

    See Modify the properties of a pour unit and Categories in Organizer.

  10. Use Organizer to categorize pours. Then you can select them by their sequence and report pour-specific information, such as pour volumes and formwork areas.

    See View object properties in Organizer and Example: Organize the model into location and custom categories, and view quantities.

  11. If you wish, use Task manager to include pour objects and pour units in tasks and to schedule pours. You can then visualize pour status information based on planned and actual dates by using Project status visualization.

    See Create a task in Task manager and Project status visualization.

  12. Create general arrangement drawings for pour units.

    Select a pour unitentity that combines together a pour object and the other building objects that need to be in place before cast-in-place concrete can be poured

    The needed building objects can be reinforcement and embeds, for example.

    using the Select assemblies switch, create a 3D viewview that displays objects three-dimensionally

    3D view is one of the default views.

    of the pour unit, and then create a GA drawingdrawing that is created from one or more model views and that shows information needed to understand the general arrangement of structural elements on a project

    General arrangement drawings show how parts, assemblies, cast units, or pour objects are located in a building.

    using the 3D view.

    This way you can automatically include in the drawing all reinforcement, embeds, and other objects that need to be shown with the pour objectbuilding object that is formed of one or more cast-in-place concrete parts, or parts of cast-in-place concrete parts

    The cast-in-place concrete parts are merged into one pour object if they have the same material grade and pour phase, and if they touch each other. Pour objects are visible in pour view.
