Certified geological surveying: geotechnical investigations with legal validity

Every geological investigation certified at the point of survey: digital signature, verified GPS metadata and complete chain of custody for boreholes and field tests.

Geological and geotechnical investigations generate large volumes of field data: borehole photographs, in-situ test videos, laboratory results and topographic surveys. These data underpin decisions on construction projects and environmental risk assessments.

The problem is that this documentation is collected with generic tools, without guarantees of date, location or integrity. When a client challenges a survey or a court evaluates an expert report, the absence of a chain of custody exposes all parties to disputes that can invalidate months of work.

TrueScreen certifies every survey at the moment of acquisition with verified metadata, digital signature and qualified timestamp compliant with eIDAS, producing documentation with full legal validity.

Needs

  • Borehole photos collected without verifiable metadata on date, time and GPS position
  • Eurocode 7 requires rigorous documentation but standardized digital tools are lacking
  • Field data remains on personal devices for days without integrity protection
  • Environmental risk assessments require geolocated evidence with certified timestamps
  • Data exchange between multiple parties without a certified format creates delays

Solution

TrueScreen enables geologists and field technicians to certify every acquisition directly at the survey point.

Borehole photographs, penetrometer test videos, laboratory documents and field reports are acquired with verified metadata (GPS coordinates, certain date and time, device parameters) and protected by a digital signature and qualified timestamp.

The result is geological documentation with a complete chain of custody, enforceable against third parties and compliant with Eurocode 7 and eIDAS requirements. Every file remains tamper-proof and traceable.

What gets certified

Boreholes and soundings

Photographs of boreholes, soundings and soil samples with certified GPS metadata and timestamps for every survey point.

In-situ tests

Videos of penetration tests, load tests and permeability tests acquired on site with automatic device parameter verification.

Documents and reports

Geotechnical laboratory analysis results, field reports and survey sheets digitally signed with tamper-proof metadata.

Surveys and environmental assessments

Topographic surveys, geological maps and environmental risk assessment documentation with certified GPS coordinates.

Expected benefits

  • Challenges to geological survey authenticity eliminated in expert and legal proceedings
  • Documentation compliant with Eurocode 7 and eIDAS with complete chain of custody
  • Geological report compilation times reduced with structured data available immediately
  • Secure sharing between geologist, engineer, client and regulatory authority
  • Full traceability with certified GPS coordinates and qualified timestamp

FAQ: certified geological surveying and geotechnical investigations

1) How does evidence certification work during geological investigations?
Geologists and field technicians capture photos, videos and documents directly at the survey point using the TrueScreen app. Every piece of content is certified at the moment of acquisition with tamper-proof metadata: date, time, GPS position, device parameters and cryptographic hash. The digital signature ensures full evidentiary value even in challenging field conditions such as remote sites or temporary investigation areas.
2) What types of content can be certified during geotechnical surveys?
You can certify borehole and sounding photographs, in-situ test videos (penetration, load, permeability), geotechnical laboratory analysis results, topographic surveys, geological maps, field reports, survey sheets, and environmental risk assessment documentation including landslide and hydrogeological instability records.
3) Is certified documentation valid as evidence in expert and legal proceedings?
The digital signature compliant with the eIDAS Regulation, together with the qualified timestamp, grants full legal validity to certified evidence. The documentation is enforceable in court, in geological expert assessments, environmental risk evaluations, and disputes between clients, designers and construction firms.
4) How is the chain of custody guaranteed for geological data collected by multiple operators?
Every acquired piece of content is individually certified with the operator identity, timestamp and GPS coordinates. Evidence flows into structured dossiers organized by campaign, site and test type, maintaining full traceability from field collection through the geological report and any legal proceedings, with no possibility of alteration or substitution.
5) Is TrueScreen compliant with Eurocode 7 for geotechnical investigations?
TrueScreen produces documentation with certified dates, guaranteed integrity and a verifiable chain of custody, supporting the rigorous technical documentation requirements set by Eurocode 7 (EN 1997). Compliance with the eIDAS Regulation and ISO/IEC 27037 standard further strengthens the validity of collected digital evidence.
6) Can TrueScreen integrate with geotechnical modelling software and GIS platforms?
TrueScreen integrates via API and SDK with GIS platforms for geological mapping, geotechnical modelling software, BIM platforms, document management systems and government portals for construction and environmental filings. Certified reports are exportable in PDF and JSON format, compatible with major systems already in use.
