BIM Model Requirements, Part 3: Building Ground Model

(currently available in german only)

The DAUB recommendation "Digital Design, Construction and Operation of Underground Structures - BIM in Underground Construction", published in May 2019, was created with the objective of providing a basic understanding of the application of BIM in underground construction. Based on this recommendation, the publication of the Model Requirements Part 1 followed one year later, which deals with the basic understanding of the model structure with uniform designations for typical tunnel construction objects and associated object information.

As part of the development of further model requirements, the document now available as Part 3 deals with the description of the ground with the aid of a digital ground model. Here, too, the focus is on the requirements from underground construction. Structural considerations for the organization of the model including the linked information and the findings of first deployments of the digital subsoil model in practice are described in this recommendation.

After an introduction and presentation of existing practice, the contribution that the foundation soil model can make to the use cases described therein is described with reference to the recommendation published in May 2019. The central chapter in this recommendation is the "Requirements for the creation of a subsoil model". This is followed by the fields of action for further developments and a short outlook on individual aspects around the role of the subsoil model.

It can be assumed that this recommendation will be repeatedly adapted to the evolving practical experience and requirements in the coming years.

All DAUB recommendations (divided into the subsections BIM, Contract, Excavation, Support, Health and Safety and Withdrawn) can be found in the download area.

The new recommendation has been assigned to the subsection "BIM (Building information modeling)".
