Abstract—Assessing the geotechnical parameters helps in improving the soil settlement which usually causes damage to the civil structure. In this study, geotechnical investigations at UET, Kala Shah Kaku Campas (KSK), Lahore site are carried out for undisturbed samples at depths of 2 ft, 3 ft, 4 ft and 5 ft. in orderto soil classification and assess the consolidation parameters on undisturbed and disturbed/remolded samples. Results indicate that the soil grade from top layer of silty clay (CL-ML) to lean clay (CL) from 3ft to 5ft depth. The natural moisture content is very low and the plastic limit varies from 20 to 23. The liquidity index shows that the soil of the study area is of semisolid or solid state. Void ratio varies from 0.70 to 0.96 for undisturbed samples and 0.60 to 0.90 for disturbed samples. Specific gravity and Bulk density range from 2.68 to 2.69 and 14.0 to 16.0 kN/m 2 respectively. The over consolidation ratio (OCR) values up to 5ft depth are in the range of 4.1 to 7.0. It is found that compressibility characteristics decrease with depth. The coefficient of primary and secondary consolidation decreases with increase in applied pressure and tends to be more or less constant at high pressures.
