NOTES RELATED TO RECORDS OF TEST BORING AND GENERALIZED SUBSURFACE PROFILE 1.Groundwater level was encountered and recorded (if shown) following the completion of the soil test boring on the date indicated. Fluctuations in groundwater levels are common; consult report text for a discussion. 2.The boring location was identified and located in the field based on measured and estimated distances from existing site features. 3.The borehole was backfilled to site grade following boring completion, patched with asphalt cold patch mix when pavement was encountered. 4.The Record of Test Boring represents our interpretation of field conditions based on engineering examination of the soil samples. 5.The Record of Test Boring is subject to the limitations, conclusions, and recommendations presented in the report text. 6.The Standard Penetration Test (SPT) was performed in accordance ASTM Procedure D-1586. SPT testing procedure consists of driving a 1.4-inch I.D. split-tube sampler into the soil profile using a 140-pound hammer falling 30 inches. 7.On the Record of Test Boring listed as “Blow Counts”, the N-value is the sum of the SPT hammer blows required to drive the split-tube sampler through the second and third 6-inch increment of the sampling layer, and is an indication of soil strength. 8.Shown on the Record of Test Boring an SPT N-value expressed as 50/2” is descriptive of the fact that 50 hammer blows were required to drive the split-spoon sampler a distance of approximately 2 inches. 9.The soil/rock strata interfaces shown on the Records of Test Boring are approximate and may vary from those in the field. The soil/rock conditions shown on the Records of Test Boring refer to conditions at the specific location tested; soil/rock conditions may vary between test locations. 10.Relative density and consistency for sands/gravels, silts/clays, and limestone are described as follows: Cohesionless Soils Silts and Clays Limestone SPT (N-Value) Relative Density SPT (N-Value) Consistency SPT (N-Value) Relative Density 0 – 3 Very Loose 0 – 1 Very Soft 0 – 19 Very Soft 4 – 8 Loose 2 – 4 Soft 20 – 49 Soft 9 – 24 Medium Dense 4 – 6 Firm 50 – 100 Medium Hard 25 – 40 Dense 7 – 12 Stiff 50 for 3 to 5” Moderately Hard Over 40 Very Dense 13 – 24 Very Stiff 50 for 0 to 2” Hard Over 24 Hard 11.Definition of descriptive terms of modifiers for silts/clays/shells/gravels are described as follows: Percentage of Modifier Material First Qualifier Second Qualifier 0 – 5 With a Trace of + Silt, Clay, Shell With a Trace 5 – 12 Slightly + Silty, Clayey, Shelly With Some 12 – 30 Silty, Clayey, Shelly With 30 – 50 Very + Silty, Clayey, Shelly And 12.Descriptive characteristics for organic content percentages are described as follows: Percentage of Organic Material Descriptor 0 – 5 With a Trace 5 – 20 With Organics 20 – 75 Highly Organic 75 – 100 Peat
