EXPLANATION OF BOREHOLE LOG This form describes some of the information provided on the borehole logs, which is based primarily on examination of the recovered samples, and the results of the field and laboratory tests. Additional description of the soil/rock encountered is given in the accompanying geotechnical report. GENERAL INFORMATION Project details, borehole number, location coordinates and type of drilling equipment used are given at the top of the borehole log. SOIL LITHOLOGY Elevation and Depth This column gives the elevation and depth of inferred geologic layers. The elevation is referred to the datum shown in the Description column. Lithology Plot This column presents a graphic depiction of the soil and rock stratigraphy encountered within the borehole. Description This column gives a description of the soil stratums, based on visual and tactile examination of the samples augmented with field and laboratory test results. Each stratum is described according to the Modified Unified Soil Classification System. The compactness condition of cohesionless soils (SPT) and the consistency of cohesive soils (undrained shear strength) are defined as follows (Ref. Canadian Foundation Engineering Manual):

Soil Sampling Sample types are abbreviated as follows:

SS Split Spoon TW Thin Wall Open (Pushed) RC Rock Core

AS Auger Sample TP Thin Wall Piston (Pushed) WS Washed Sample

Additional information provided in this section includes sample numbering, sample recovery and numerical testing results. Field and Laboratory Testing Results of field testing (e.g., SPT, pocket penetrometer, and vane testing) and laboratory testing (e.g., natural moisture content, and limits) executed on the recovered samples are plotted in this section. Instrumentation Installation Instrumentation installations (monitoring wells, piezometers, inclinometers, etc.) are plotted in this section. Water levels, if measured during fieldwork, are also plotted. These water levels may or may not be representative of the static groundwater level depending on the nature of soil stratum where the piezometer tips are located, the time elapsed from installation to reading and other applicable factors. Comments This column is used to describe non-standard situations or notes of interest.

MODIFIED * UNIFIED CLASSIFICATION SYSTEM FOR SOILS

*The soil of each stratum is described using the Unified Soil Classification System (Technical Memorandum 36-357

prepared by Waterways Experiment Station, Vicksburg, Mississippi, Corps of Engineers, U.S Army. Vol. 1

March 1953.) modified slightly so that an inorganic clay of "medium plasticity" is recognized.
