SNT 3.04.03-2016 PDF

Full title and description

SNT 3.04.03-2016 — National normative document specifying requirements, procedures and criteria for engineering surveys, design, construction and maintenance related to ground investigations and geotechnical aspects for buildings and civil infrastructure. The standard provides guidance on collection and interpretation of geotechnical data, testing of soils and rocks, documentation of results and recommendations for foundation design and slope stability in the national context where SNT series applies.

Abstract

This standard sets out required practices for subsurface investigations, field and laboratory testing of soils and rocks, reporting formats and minimum information to be provided for safe and reliable geotechnical design and construction. It addresses site investigation planning, borehole and test pit execution, in-situ testing (such as penetration and shear tests), sampling, laboratory classification and strength testing, groundwater monitoring, and preparation of geotechnical reports including recommendations for foundations, earthworks and retaining structures.

Scope

The standard applies to planning and execution of geotechnical site investigations for new construction, reconstruction and major repairs of buildings, industrial facilities, transport infrastructure and hydraulic structures. It covers methods for obtaining subsurface information needed for foundation selection and design, earthworks specification and assessment of geohazards such as landslides, subsidence and soil liquefaction. The document is intended for use by surveyors, geotechnical engineers, designers, contractors and regulatory authorities to ensure consistent quality of geotechnical data and recommendations.

Key topics and requirements

• Planning of geotechnical investigations: scope, objectives, and required level of detail.
• Field investigation methods: boreholes, test pits, sampling procedures and in-situ tests (e.g., standard penetration test, cone penetration, vane shear).
• Groundwater observation and monitoring during and after site works.
• Laboratory testing: soil classification, index properties, consolidation, shear strength and compressibility tests.
• Data interpretation: estimation of engineering parameters, bearing capacity, settlement prediction and slope stability assessment.
• Reporting requirements: content, required drawings, soil logs, test results and clear foundation/earthwork recommendations.
• Recommendations for foundation types, ground improvement and mitigation measures for adverse ground conditions.
• Health, safety and environmental considerations during geotechnical investigations.

Typical use and users

Used by geotechnical and civil engineers, site investigation contractors, structural designers, construction project managers and permitting authorities. Typical applications include foundation design for buildings and bridges, assessment of embankments and slopes, design of retaining structures, planning of ground improvement works and evaluation of sites for infrastructure projects.
