Reinforcement modeling

Use Case Definition

Two essential bases are required for the design of reinforcement in reinforced concrete:
The exact geometry of the structure to be executed with recesses and built-in parts (formwork dimensions), and the structural analysis (see Section 4), which, in addition to design information (e.g. maximum bar diameters or minimum spacing), includes the statically required amount of reinforcement for each component and its distribution.
The reinforcement model is modeled as an independent structural design model. 
A structural model is used as the model basis from which the formwork plans can be derived. This formwork model, if you want to call it that, must fulfill both the geometric (LOG) and attributive requirements (LOI) necessary for accurate execution planning.
The reinforcement model created with a BIM authoring tool is then used in the subsequent BIM processes for quality assurance, coordination, quantity takeoff and can also serve as the basis for the automated creation of reinforcement components in prefabrication.

The documents reflect the current best practice and do not claim to be complete. They should not to be understood in the sense of a generally valid recommendation or guideline from a legal point of view. The documents are intended to support appointing and appointed parties in the application of the BIM method. The documents must be adapted to the specific project requirements in each case. The examples listed do not claim to be complete. Its information is based on findings from practical experience and is accordingly to be understood as best practice and not universally applicable. Since we are in a phase in which definitions are only emerging, the publisher cannot guarantee the correctness of individual contents.
