Use Case Definition

The use case «Model-based layout of reinforcement» describes the requirements and implementation for placing to be able to place reinforcement on the construction site from the execution model.

Aim and scope

The use case defines the necessary requirements for the structured reinforcement design models and their information content. This enables the following points:

  • Consistent information flow
  • Better inventory planning for the executing companies
  • An improved quality of the reinforcement due to
    • a higher quality, executable planning
    • the possibility of dynamic section
    • a better comprehensibility and therefore less misinterpretations
  • Easy use of execution models for the executors
  • Use of models instead of plans on the construction site


  • how reinforcement design models can be used on the construction site
  • better, more informative execution prinipals on the construction site
  • increased efficiency by avoiding redundant of work
  • error reduction for planning and execution
  • optimization of material flows and just-in-time deliveries
  • No need for plans, both in digital and printed form


  • Reinforcement is created (form, placement)
  • Concerns mainly in-situ concrete construction, no precast producers
  • No logistics and ordering processes
  • The CDE and the data storage is defined in the use case «create execution model».


  • Use Case «Create Digital Execution Model» 
  • Use Case «Staging with Views from the Model»

Software, Tools & Services

The following services support the use case «model-based layout of reinforcement»

BuildingPoint Schweiz AG - Tekla Structures / simplebim




The quality and efficiency of modeling and data delivery are critical success factors for model designers (e.g., civil engineers) and performers (e.g., builders).

The success of a model-based construction site starts in the planning phase. The parametric execution model for cast-in-place concrete from Tekla already uses the standardized Exchange Requirements (ER) of the use case «model-based layout of reinforcement» and thus ensures the necessary IFC data quality.

This allows the model designer to concentrate on the optimal design and the executors on the construction. A data check is recommended if the model creator did not use the Exchange Requirements (ER) of the use case during modeling.

  • Parametric modeling of reinforcement and built-in parts according to the use case «model-based layout of reinforcement».
  • Integrated check of the Exchange Requirements during modeling
  • Automated data generation according to concreting sections
  • Direct upload to the CDE Trimble Connect
  • Easy to use thanks to intuitive viewers on the construction site
  • Check routine of the use case for IFC with simplebim

ALLPLAN Schweiz AG – Allplan / Bimplus

With the BIM software Allplan, the model creator can generate the reinforcement models in the familiar environment and export them in an IFC- and Use Case compliant manner using integrated standard favorites. The attribute and export settings required for this were implemented according to the information requirements in this use case and can be used directly by the user. This ensures that the model and information quality of the execution data is guaranteed.

The reinforcement models are uploaded to the CDE platform (Bimplus) by the engineering office in accordance with the stages and made available to the master builder by means of approval. The reinforcement data can be freely compiled according to the user's wishes using attribute filters (sorting by stage, concreting section, location, etc.) and the reinforcement can be efficiently installed in this way.
