Certain conditions preclude soil from being classified as Type A. For example, no soil is Type A if it is fissured or has been previously disturbed. See Appendix A to Subpart P of Part 1926, paragraph (b) – Definitions (Type A), for a detailed definition of Type A soil. Type B – Includes cohesive soil with an unconfined compressive
These classifications are based on the size of the particles that make up the soil. Sand particles are the largest, ranging in size from 0.05 mm to 2 mm. Silt particles are smaller, ranging in size from 0.002 mm to 0.05 mm, while clay particles are the smallest, measuring less than 0.002 mm in size.
4.3.1.6 Weathered State of Rock. Weathering is the process of mechanical and/or chemical degradation of the rock mass through exposure to the elements (e.g. rain, wind, ground water, ice, change in temperature etc.). In general, the strength of the rock tends to decrease as the degree of weathering increases.

Note: Excavation of trenches for …
Silty Soil: It's super soft, almost like your favorite fluffy pillow. But beware! It compact easily and holds water well, making it tricky for excavation. Clay Soil: The sticky wicket of the lot. It's heavy, hard to dig, and retains water – making it a potential excavation nightmare. Loamy Soil: The Goldilocks of soils.
The scope of work associated with excavation encompasses several crucial tasks conducted before, during, and after the excavation process: Setting out corner benchmarks. Surveying ground levels and top levels. Excavating to approved depths. Dressing loose soil and ensuring compliance with cut-off levels.
Type A Soil. "Type A" means cohesive soils with an unconfined, compressive strength of 1.5 ton per square foot (tsf) (144 kPa) or greater. Examples of cohesive soils are: Clay, Silty clay. Sandy clay. Clay loam and. In some cases, silty clay loam and sandy clay loam. Cemented soils such as caliche and hardpan are also considered Type A.

Dry silt soil. It can stand vertically and the depth of excavation of more than 15m with slight cementing on the face can be achieved. If such slopes are not cemented, then vibration would easily disturb their stability. Another undesired factor that lead to destabilize slopes in silt is the erosion due water.
Stripping is a type of excavation that revolves more around clearing a large area rather than digging a pit or a trench, for example. Before construction or engineering projects can begin, an area may need to be cleared of topsoil, gravel, sand, rocks, and so on and grading might need to be done. In such cases, excavation will consist of ...
