What is a GeotechTypicalSection?
Interval along the alignment/building structure with similar ground conditions, as part of the GeotechSynthesis model that represents the connection between the ground model and the building. Includes key-properties like expected distribution of ground types (reference to GeotechUnits) and baseline-definition of expected ground conditions and potential hazards, and may also include key-information on design like excavation measures, distribution of support types etc.

| OGC LandInfra | FacilityPart | Land and Infrastructure facility, such as a road or bridge. A facility has a life cycle, including planning, design, construction, maintenance, operation, and removal phases The design and construction phases are typically performed as part of a project. There may be multiple such projects during the life cycle of the facility to enable phased construction and incremental improvement. |
| ISO 19148 | FeatureEvent | The FeatureEvent interface is used to linearly reference a feature along a LinearElement and possibly further qualified as applying at an instant in, or during a period of, time. |
Note: the GeotechTypicalSection can be seen on different aspect and then have multiple realizations:
- a part of a tunnel (a part of a facility)
- an event along an alignment.
