Ground investigation and ground profiles

What this module covers

• Explain why ground investigation is phased and risk-driven, starting with a desk study
• Match investigation methods to the ground and to what must be measured
• Distinguish disturbed, bulk and undisturbed samples and their uses
• Apply the standard SPT energy normalisation and know its limits
• Assemble borehole logs into a ground profile, and state its residual uncertainty
