• Geotechnical engineers need to

know where the building columns are

being planned/re-planned

• Structural/Civil engineers need to

know where we have known ground

conditions

• BIM is about using data – not just putting it in a model

• The more data we have, earlier, the better we can plan

and develop the project

How do we collect/manage Geotechnical

Data?

Many tools for this, at ByrneLooby:

• Data Management Tool – HoleBase SI

• Data Interpretation Tool – HoleBase SI Extension for

Excel

• Data Visualisation Tool – HoleBase SI Extension for

AutoCAD Civil 3D

Presenting Borehole Data:

In Civil 3D Extension :

• Fast and Intuitive Interface

• Data dynamically linked to HoleBase SI Database

• 2D and 3D Boreholes instantly drawn without any

AutoCAD commands

Andy Wilkins

• Geotechnical Data central to BIM

• AGS Data specification and requirement central to this

process

• Geotechnical BIM Tools (such as HoleBase SI) allow:

• Efficient Storage and Management of Data

• Dynamically linked visualisation of that Data in standard format

which can be utilised by all with BIM environment
