Stability of a building is of paramount significance in Civil Engineering, and this is why the foundation materials (soil, rock, etc.) are given so much attention. A subfield of Civil Engineering, Geotechnical Engineering is concerned with the use of soil and rock properties and behaviours in engineering projects. Various laboratory tests must be conducted to ensure the structure’s excellent stability and quality. Included in this lab manual are procedures for performing tests such as compaction, permeability testing using a constant head and a falling head consolidation test, and determining the grain size distribution of a soil sample using a dry sieve, a wet sieve, and a hydrometer. The California bearing ratio, in-situ density, and shear strength were all measured using direct shear, unconfined compressive, and unconsolidated undrained triaxial compression (uu) tests and vane shear, respectively.
