Structural Soils Bristol Laboratory

Structural SoilsBristol

UKAS 1774 issue 048 allocates the Bristol laboratory to 1A Princess Street, Bedminster. Its pages 3–8 list concrete-core compression, rock characterisation and mechanical methods, soil classification/strength/consolidation and selected mixture tests. Castleford, Hemel Hempstead and off-site methods have separate allocations.

Key facts

Separate laboratory allocation
1A Princess Street, Bedminster, Bristol, BS3 4AG. UKAS 1774 issue 048 dated 22 June 2026 separates this laboratory from the organisation header, the other two laboratories and off-site field activities.

Testing capabilities

Rock and concrete-core characterisation

The Bristol allocation includes concrete-core examination/compression, rock compressive strength/deformability, point-load and Brazilian/splitting tensile methods, porosity/density, slake durability, Cerchar abrasivity and P/S-wave measurement.

Soil strength, consolidation and physical methods

Bristol methods include soil classification, CBR and compaction, vane/shearbox/ring-shear, unconsolidated and consolidated triaxial tests, oedometer/consolidation, permeability, thermal conductivity/resistivity and electrical resistivity, with their separate references.

Equipment and published limits

Standards and accreditation

UKAS 1774 — specific laboratory allocation
Issue 048 dated 22 June 2026 states ISO/IEC 17025:2017 and lists method-specific BS 1377, BS EN ISO 17892, ISRM and other references under separate laboratory sections. Confirm the particular product/method and listed edition; accreditation is not a combined group-wide scope.

What to confirm with the facility

  • The Old School, Stillhouse Lane, BS3 4EB is the organisation header address; Bristol laboratory methods are allocated to 1A Princess Street, BS3 4AG. Other-site and Site-code field methods are not assigned to this laboratory.
  • Confirm the exact product/method allocation, specimen preparation, usable capacity, current accreditation scope, availability, reporting and quotation.

    United Kingdom Accreditation Service (UKAS) · Reviewed

    Issue 048 dated 22 June 2026 identifies separate Bristol, Castleford, Hemel Hempstead and Site allocations. Only the Structural Soils Bristol Laboratory methods above are adopted; shared organisation headers and other-location methods never create local scope.
