Geotechnical Investigation EN ISO 22475
This object type supports standardized documentation of geological and geotechnical investigations in accordance with EN ISO 22475 and related standards. It is designed for recording boreholes, groundwater monitoring points, and wells, including associated field and laboratory data.
Overview
The object type "Geotechnical Investigation EN ISO 22475 (2018)" is a further development of the earlier 2007 version. It enables comprehensive acquisition, evaluation, and graphical representation of geotechnical data using standardized input forms, dictionaries, layouts, and database structures.
For current projects, the 2018 object type [ENISO002] is recommended and is provided to all GeoDin users via the GeoDin server.
Working with the object type
Detailed soil and rock description
Soil and rock characteristics can be recorded in detail using dedicated input forms, including:
Discontinuities
Degree of decomposition
Consistency
Degree of weathering
Rock strength
Rock quality
Cored section boundaries
These forms are available in German/Austrian and English.
Advanced layer data handling
Layer data include selection dialogs that provide access to additional input forms for detailed geological descriptions, ensuring consistent and standardized data entry.
Standard-compliant layouts
Predesigned layouts allow output in accordance with:
DIN 4943
EN ISO 22475
EN ISO 14688
EN ISO 14689
Geological fill patterns comply with:
DIN 4023
ÖNORM EN ISO 14688/14689
BS 5930‑1990
Visualization outputs
Available layouts include:
Trial pit visualization (ÖNORM)
Borehole logs according to EN ISO 14688/14689
Drilling profiles and well design according to DIN 4943
Technical notes and compatibility
The object type uses the new descriptor (E2) due to technical adjustments.
Full functionality is available from GeoDin version 9 onwards.
The object type is not downward compatible with earlier GeoDin versions.
Recording groundwater levels
For the object types "Geotechnical Investigation EN ISO 22475 (2007/2018)" [ENISOBOR/ENISO002], groundwater levels are entered in a dedicated table rather than in the layer log (as is standard for the SEP1 standard).
To record groundwater levels:
Start the Data management method.
Select the Bescheide, Grundwasser or Grundwasser button (depending on your GeoDin version) in the upper toolbar.
If the groundwater table is not displayed, click Choose table in the right-hand toolbar.
Select Groundwater in the list and confirm with OK.
The location of the groundwater table differs by version: up to GeoDin 8 it appears under the object type "Geotechnical Investigation EN ISO 22475 (2007)" [ENISOBOR]; from GeoDin 9.0 onward it appears under "Geotechnical Investigation EN ISO 22475 (2018)" [ENISO002].
The SEP3 borehole database object type records groundwater levels the same way. German-speaking users can find the full SEP3 guidance in the German Help Center article Grundwasserstaende erfassen bei EN ISO 22475 und SEP3 (Deutsch).
Reference: Standards and normative references
The object type is based on the following standards:
DIN / ÖNORM EN ISO 22475 (2007/2006)
DIN / ÖNORM / SN EN ISO 14688‑1 / 14688‑2
DIN / ÖNORM / SN EN ISO 14689 (2020)
DIN 4943 (2013)
These standards define the structure, terminology, symbols, and layouts used for soil and rock description, borehole logging, and well documentation.
