A Connected Alternative
Move Beyond Disconnected Test Spreadsheets
Individual spreadsheets may calculate one test, but they often separate measurements, formulas, plots, reports and historical records.
- Repeated entry of project, sample and specimen information
- Formula and formatting differences between users or files
- Difficult retrieval of measurements behind a reported value
- Manual recreation of test tables and engineering curves
- Laboratory results isolated from the wider project record
GDMS keeps the test context together: project, sample, specimen, measurements, calculations, graphs and standardized output.
Core Capabilities
A Managed Geotechnical Laboratory Workflow
GDMS combines practical test processing with structured records that remain useful after the report is issued.
Project and Sample Records
Organize tests by project, sample, material, specimen and test type in a managed database.
Test-Specific Calculations
Derive applicable engineering values from recorded measurements using repeatable workflows.
Tables and Engineering Curves
Generate the calculations, classifications, tables and graphs required by the selected test.
Quality-Control Review
Review specimen details, units, required inputs, calculations and exceptions before reporting.
Standardized Reports
Produce consistent result sheets while retaining the connection to the supporting test data.
GaeaSynergy Integration
Keep laboratory information available within the wider project environment where licensed.
Supported Testing Scope
Four Principal Material Groups
Test forms, inputs, calculations and outputs are organized according to the applicable material and engineering workflow.
SOIL AND AGGREGATES
Classification, Hydraulic and Strength Properties
Examples include grain size, Atterberg limits, moisture, specific gravity, compaction, CBR, permeability, consolidation, direct shear and compression testing.
CONCRETE, GROUT AND MORTAR
Specimen and Strength Testing
Manage compressive, flexural and splitting-tensile workflows with specimen measurements and calculated strength results.
ASPHALT
Binder, Density and Performance Testing
Workflows include bitumen content, viscosity, bulk and maximum specific gravity, nuclear density and Marshall stability.
ROCK
Index and Compressive Strength Testing
Manage rock water content, point-load strength, unconfined compression and triaxial compression results.
Product and Professional Scope
Understand the GDMS Deployment and Review Boundary
Separate the laboratory workflow provided by GDMS from the wider project context and the professional responsibilities of the laboratory.
GDMS Licensing and GaeaSynergy Integration
GDMS has its own product and licensing path for laboratories that need managed geotechnical test data, calculations and reports.
- Use GDMS for supported laboratory test workflows and reporting
- Select an access configuration appropriate to the laboratory team
- Use applicable GaeaSynergy capabilities when wider project integration is licensed
- Confirm current single-user, network and concurrent-access options before purchase
Standards and Professional Responsibility
GDMS supports structured laboratory workflows and calculations. Software use by itself does not establish compliance with a test standard or approve a result.
- Select the method and revision applicable to the project
- Confirm required apparatus, preparation and measurement procedures
- Verify calculations, units, classifications and engineering curves
- Apply the laboratory’s QA/QC and authorization procedures
- Approve final results through qualified personnel
Laboratory responsibility: The laboratory remains responsible for current standard requirements, method suitability, technical review and final acceptance.
Calculation Traceability
Follow Every Result from the Source Reading to the Report
GDMS keeps the working context visible through six connected stages of the laboratory record.
1
Project and Sample
Identify the project, material, sample and requested test.
2
Specimen Measurements
Record masses, dimensions, loads, readings and observations.
3
Calculations
Derive the values required by the supported test workflow.
4
Curves and Classification
Generate applicable plots, tables and material classifications.
5
Technical Review
Check inputs, units, calculations, graphs and exceptions.
6
Standardized Report
Issue consistent output linked to its supporting record.
Why traceability matters: A reported value can be evaluated together with the measurements, calculation context and technical presentation that produced it.

Evaluation Context
Why Move Beyond Spreadsheets and Standalone Test Programs?
Choose software by how well it preserves the complete laboratory record—not simply whether it can reproduce one calculation or report.
| Evaluation Area | Spreadsheets | Standalone Test Program | GDMS |
|---|---|---|---|
| Test context | Repeated in individual files | Usually limited to one test family | Projects, samples, materials, specimens and tests |
| Calculations | User-maintained formulas | Structured for the supported test | Test-specific calculations across multiple material groups |
| Source measurements | May be separated from final reports | Retained within the standalone database | Connected to calculated values and reports |
| Standardization | Varies by workbook and user | Consistent within the test program | Consistent forms and reports across supported workflows |
| Retrieval | File and folder searches | Search within one test application | Managed project and laboratory records |
| Project integration | Manual export and re-entry | Usually limited | Wider GaeaSynergy context where licensed |
Evaluate with your own requirements. Confirm every governing method, calculation, field, quality-control step, report layout and approval responsibility using representative laboratory cases.
Before You Decide
Evaluate GDMS Against Your Laboratory Program
A useful evaluation uses real workflow requirements rather than a generic feature checklist.
- Material groups and test methods currently performed
- Required measurements, units, calculations and engineering curves
- Quality-control checks and reviewer responsibilities
- Client, agency and internal report formats
- Historical data and WinSieve migration requirements
- Single-user, network and concurrent-access needs
- GaeaSynergy, WinLoG, WinFence or other project integration
- Training, maintenance and technical-support expectations
Recommended Evaluation Path
- Review the supported test types.
- Inspect representative report examples.
- Watch the GDMS workflow demonstration.
- Download and test the demonstration version.
- Compare results with approved laboratory cases.
- Contact GAEA about licensing or migration questions.
