Geotechnical observations can affect design, safety and construction decisions. Voice capture can preserve site context and handover detail, but formal logs, test results and engineering assessment must remain controlled.
Anchor every note to location and depth
State the project, borehole, trial pit or inspection ID, coordinates or chainage, depth interval, time and activity. Repeat the identifier after interruptions or movement to another location.
Keep four evidence layers distinct
| Layer | Examples |
|---|---|
| Observation | Material, groundwater, instability or visible condition |
| Process behaviour | Drilling, sampling or excavation response |
| Controlled evidence | Sample, test, photograph, instrument or log reference |
| Interpretation | Preliminary ground model or design concern |
Do not allow an AI summary to turn a preliminary interpretation into a verified stratum, parameter or design conclusion.
Create a complete spoken field item
- Location and depth interval.
- Neutral material description.
- Groundwater or inflow observation.
- Sampling or test reference.
- Recovery or disturbance information.
- Unexpected condition.
- Immediate safety or operational action.
- Evidence and follow-up required.
Verify units and identifiers
Depths, sample numbers, test values and technical terms should be checked against the formal log, instrument or laboratory record. Speech recognition must not become the only source for design-relevant data.
Handle unexpected conditions safely
Instability, services, contamination indicators, gas, water or other urgent concerns should follow the project's immediate safety and escalation process before routine transcription. Record the action and notifications afterwards.
Connect shift handover to evidence
A useful handover should identify work completed, depth or location reached, samples and tests outstanding, plant or access constraints, safety controls and the next required activity. Use one accountable owner for each unresolved action.
Transfer into controlled records
- Preserve the source recording.
- Correct IDs, depths, units and terminology.
- Match samples, photographs and test records.
- Complete formal borehole, trial-pit or inspection logs.
- Separate factual observations from engineering interpretation.
- Apply project review and approval.
Record limitations
State access, visibility, sampling, equipment or weather limitations. A complete geotechnical record shows what could not be confirmed as well as what was observed.
How NERALVO Halo fits
NERALVO Halo can support approved site observations and shift handovers. DOWAY drafts should never replace formal logs, tests or calculations.
Bottom line
The strongest workflow uses audio to preserve context while ensuring every design-relevant statement remains traceable to verified site and test evidence.
