A boring log is a description of exploration procedures and subsurface conditions encountered during drilling, sampling and coring.

Learning Objectives

At the successful conclusion of this course, you’ll be able to identify and discuss:
  • Topographic survey data including boring location and surface elevation, and bench mark location, and datum, if available.
  • An accurate record of any deviation in the planned boring locations.
  • Identification of the subsoils and bedrock including density, consistency, color, moisture, structure, geologic origin.
  • The depths of the various generalized soil and rock strata encountered.
  • Sampler type, depth, penetration, and recovery.
  • Sampling resistance in terms of hydraulic pressure or blows per depth of sampler penetration.
  • Size and type of hammer; Height of drop.
  • Soil sampling interval and recovery.
  • Rock core run numbers, depths & lengths, core recovery, and Rock
  • Quality Designation (RQD)
  • Type of drilling operation used to advance and stabilize the hole.
  • Comparative resistance to drilling.
  • Loss of drilling fluid.
