BIM – how to apply it to Geotechnics. In recent years we often hear about BIM-Building Information Modeling – generally associated with the three-dimensional modeling applied to architecture, sometimes it even looks like BIM cannot have connections with other disciplines, much less with Geology and Geotechnics.
However, being a method, BIM can be applied to different disciplines: applying it to Geotechnics is feasible and can bring several benefits, for example, a realistic saving in time and cost regardless of the software you use.
Designing in “BIM oriented” mode means communicating with colleagues and partners using other software, without any loss of quality of the project and with the preservation of all the data in it.
Geostru software, as it is known to our users, allows data interoperability through the edp format. Using this format, you can transfer information from one software to another without losing information.
Edp format is an open Geostru format, structured with ASCII encoding but not suitable for global sharing.
At present, there are two “sharing” formats specially developed for the transfer of geotechnical data. One is DIGGS, from the American Society of Civil Engineers and the other one is AGS, from the Association of Geotechnical and Geoenvironmental Specialists.
These formats set the codes, elements, and fields to use. The data is interchangeable between the two formats, with only a few semantic differences in the way of use.
We recently made our software compatible with the AGS4 format. AGS files are structured in data groups and are ASCII type. For a more complete treatment refer to: http://www.ags.org.uk/data-format/
This is a list of data groups currently supported by Geostru software
An example of AGS file can be downloaded from the previous link. It is developed with dynamic penetrometric test software, the file has been validated by the validation procedure provided by the Association of Geotechnical and Geoenvironmental Specialists.
The AGS4 and IFC.ix files for data transfer are the basis of the BIM process.
