Borehole log — soils sequence

- BS 5930 · BS EN ISO 14688 / 14689 · ASTM D1586 · AGS 4.1
- Status
- Approved record · anonymised
Plate OUT-01 · select to enlarge
1 · Description
Production log sheet: depth and elevation scales, USCS group symbols, stratum descriptions with top/bottom levels, sample type and interval, SPT increments with computed N, fines content, hammer weight and casing details — regenerated on every data change.
2 · Standards annotations
| Field · standard | Basis |
|---|---|
| Stratum descriptionsBS EN ISO 14688-1/-2 · BS 5930 §35 | Soil naming, secondary constituents, and colour terms written in fixed dictionary order — no free text. |
| USCS group symbolsASTM D2487 | SM / ML / CL assigned by the classification engine from grading and plasticity, not typed by the logger. |
| SPT increments and NASTM D1586 · BS EN ISO 22476-3 | Blow counts recorded per increment; N is the sum of the second and third increments, refusal shown as 50/xx and flagged R. |
| Clay qu — unconfined compressive strengthASTM D2166 · ASTM D2573 · BS 1377-7 | For cohesive clay, qu is the unconfined compressive strength recorded against the interval where it was measured — by field penetrometer or vane in the hole, or by laboratory UCS once tested. The engine computes cᵤ = qu / 2, so clay strength is carried on the log and not only on the rock runs. |
| Log structure and exportAGS 4.1 (LOCA, GEOL, SAMP, ISPT) | Every plotted element resolves to one AGS group and heading, dictionary-checked before export. |
Borehole log — rock coring and recovery

- Approved record · anonymised
Plate OUT-02 · select to enlarge
1 · Description
Continuation sheet through weak rock: core runs, weathering and fracture descriptions, TCR / RQD / SCR percentages, fracture index and point-load strength, plotted against the same depth datum as the soils sequence.
2 · Standards annotations
| Field · standard | Basis |
|---|---|
| Rock descriptionsBS EN ISO 14689 · BS 5930 §36 | Strength, weathering grade, fracture state and colour recorded as coded terms, then rendered to text. |
| TCR / SCR / RQDBS 5930 §26 · ASTM D6032 | Computed from measured run and piece lengths by the standards engine, never typed on the log. |
| Fracture index and rock qu (UCS)Eurocode 7 · ASTM D7012 · ASTM D5731 | Fractures per metre and intact rock strength — qu measured directly as UCS, or correlated from the point-load index Is₅₀ — kept with the run they were measured on and unit-checked before export. The same qu heading carries clay strength on the soils sheet, so the two are never mixed. |
| Continuation integrityAGS 4.1 (CORE, GEOL, DETL) | Depths, elevations and stratum boundaries carry across pages from one record — no re-keying between sheets. |

2 · Standards annotations
| Field · standard | Basis |
|---|---|
| Shear parameters c′, φ′ASTM D3080 · BS 1377-7 | Derived from the retained stress path per specimen; characteristic value selection stays with the engineer under Eurocode 7 §2.4.5.2. |

| Units and precisionBS 1377-1 · AGS 4.1 unit dictionary | Units and decimal precision fixed per heading, so no sheet reports a value the AGS file cannot express. |

2 · Standards annotations
| Field · standard | Basis |
|---|---|
| Normal stress stagesASTM D3080 §11 | Each stage retained as its own series so the peak is read from data, not from a redrawn envelope. |
| Specimen conditionASTM D3080 §9 | Disturbed / undisturbed and soaked / unsoaked recorded as governed fields, never as a note. |
| Shear rateASTM D3080 §10 | Rate stored with the test so drainage assumptions can be re-checked years later. |

Factual report workflow
Beta capabilityCreate, review, and prepare factual reports with confidence.
G& can create factual report content from approved records and review factual reports for scientific problems, data accuracy, missing evidence, internal inconsistencies, and standards alignment. Findings are returned as comments with a submission-readiness view so the team can resolve issues before sending the report to a client.
The report review workflow is currently in beta and is not yet 100% available in the current release. Final technical acceptance and sign-off remain with the responsible engineer.

Governing standards
Every annotation above resolves to a versioned standard.
Standards are held as versioned data in G&, not as report settings. Each derived value on a deliverable carries the standard and edition that produced it, so a sheet reprinted years later states the same basis it was signed under.
