A geotechnical engineer is conducting a site investigation to determine the bearing capacity of a soil layer for the foundation of a building. A standard penetration test (SPT) was performed, and the blow counts at depths of 2 m, 3 m, and 4 m were recorded as 12, 19, and 27 blows, respectively. The weight of the SPT hammer is 63.5 kg, and the height of fall is 760 mm. The diameter of the SPT sampler is 50.8 mm. Assuming an average correction factor of 0.6, determine the corrected N value at a depth of 3.5 m, and calculate the bearing capacity of the soil layer.
