Soils Analysis/Classification

• Note: soil does not need to be reclassified every inspection but should be reviewed & updated if conditions change

• SOIL CLASSIFICATION AND IDENTIFICATION The OSHA Standards define soil classifications within the Simplified Soil Classification Systems, which consist of four categories: Stable Rock, Type A, Type B, and Type C. Stability is greatest in Stable Rock and decreases through Type A and B to Type C, which is the least stable. Appendix A of the Standard provides soil mechanics terms and types of field tests used to determine soil classifications. 1.​Stable Rock • Natural solid mineral matter that can be excavated with vertical sides and remain intact while exposed. 2. Type A Soil • Cohesive soils with an unconfined compressive strength of 1.5 tons per square foot (TSF) or greater. • Cemented soils like caliche and hardpan are considered Type A. Soil is NOT Type A if: • It is fissured. • The soil is subject to vibration from heavy traffic, pile driving or similar effects. • The soil has been previously disturbed. • The material is subject to other factors that would require it to be classified as a less stable material. • The exclusions for Type A most generally eliminate it from most construction situations. 3. Type B Soil • Cohesive soil with an unconfined compressive strength greater than .5 TSF, but less than 1.5 TSF. • Granular cohesionless soil including angular gravel, silt, silt loam, and sandy loam. • The soil has been previously disturbed except that soil classified as Type C soil. • Soil that meets the unconfined compressive strength requirements of Type A soil, but is fissured or subject to vibration. • Dry rock that is unstable. 4.​Type C Soil • Cohesive soil with an unconfined compressive strength of .5 TSF or less. • Granular soils including gravel, sand and loamy sand. • Submerged soil or soil from which water is freely seeping. • Submerged rock that is not stable.
