EQuIS Geotech Reports – Shared Attributes

Some of the EQuIS Geotech reports that use Microsoft Excel template files share methods to display different report attributes, including the following:

These methods include various queries that are each associated with a specific EQuIS field name. These queries are stored under an associated field name and can perform calculations, simple decision logic, and incorporate data from database fields. This field name can then be used to populate the output report. These components are determined based on the data available to use for each sample.

This article provides details for each of the Shared Attribute methods, including use of the Name Manager functionality in Excel and the EQuIS source of the information. The Shared Attribute documentation applies to the following EQuIS Geotech reports:

•Atterberg Limits

•Atterberg Limits 3 Point

•Compaction

•CPT Parameters

•CPT - Pore Pressure Dissipation

•Gradation (Hydrometer) - ASTM D7928

•Gradation (Sieve) - ASTM D6913

•Grain Size Analysis

•Lab Forms

•Lab Summary

•Unconfined Compression

•Unconsolidated Undrained

•Water Content vs. Depth

Note: Some of the listed EQuIS Geotech reports have slightly different or additional Excel Name Manager configurations in the Excel templates, as noted in the corresponding report articles.

USCS Classification (per ASTM D2487)

This shared component automatically determines the appropriate Unified Soil Classification System (USCS) Symbol/Description based on laboratory results from a grain size analysis and an Atterberg limits test as specified by ASTM D2487. This autoclassification can only be executed if sufficient Sieve and Atterberg Limits data are available.

•Override option in DT_SAMPLE_PARAMETER with SAMPLE_DESC or SAMPLE_USCS

Excel Name Manager Field	EQuIS Source	Description
uscs_desc	Automatically calculated or populated from DT_SAMPLE_PARAMETER.PARAM_CODE = ‘samp_classification’	USCS description
uscs_symbol	Automatically calculated or populated from DT_SAMPLE_PARAMETER.PARAM_CODE = ‘sample_uscs’	USCS symbol
uscs_desc_symbol	Automatically calculated	Formatted USCS description with USCS symbol in parenthesis

AASHTO Classification (per ASTM D3282, AASHTO M145)

The American Association of State Highway and Transportation Officials (AASHTO) classification automatically determines the appropriate AASHTO group classification for a sample based on laboratory results from a grain size analysis and an Atterberg limits test. This autoclassification is based on AASHTO M145.

Excel Name Manager Field	EQuIS Source	Description
aashto_classification	Automatically calculated	Autoclassification of AASHTO Group Classification and Group Index
aashto_coarsematerial	Automatically calculated	Determines the percent coarse material based on the AASHTO definition for coarse material (% Coarse Material > 2.0 mm)
aashto_sand	Automatically calculated	Determines the percent sand based on the AASHTO T-88 definition for sand (2.0 mm < % Sand < 0.074 mm)
aashto_fines	Automatically calculated	Determines the percent fines based on the AASHTO T-88 definition for fines (% Fines < 0.075 mm)

aashto_clay	Automatically calculated	Determines the percent clay based on the AASHTO T-88 definition for clay (% Clay < 0.002 mm)

USDA Classification

Excel Name Manager Field	EQuIS Source	Description
usda_classification	Automatically calculated or populated from DT_SAMPLE_PARAMETER.PARAM_CODE = ‘sample desc’	USDA description
usda_sand	Automatically calculated	USDA percent sand
usda_silt	Automatically calculated	USDA percent silt
usda_clay	Automatically calculated	USDA percent clay

Atterberg Limits

The Atterberg Limits Shared Component gathers the Liquid Limit and Plastic Limit values and calculates the Plasticity Index.

•Report will round the LL, PL, PI values to whole numbers in case the data are entered with decimals in the database.

•Nonplastic reporting of Liquid Limit and Plasticity Index: If the value is 0 or below, then it should report the text 'NP'.

Excel Name Manager Field	EQuIS Source	Description
LL	DT_GEO_RESULT.GEO_RESULT_CODE = 'Att_LL' where DT_GEO_TEST.TEST_TYPE = 'Atterberg'	Liquid limit
PL	DT_GEO_RESULT.GEO_RESULT_CODE = 'Att_PL' where DT_GEO_TEST.TEST_TYPE = 'Atterberg'	Plastic limit
PI	Automatically calculated	Calculated plasticity index

Sieve Analysis Results

The Sieve Shared Component determines the percentage of different particle sizes in a sample. This component filters the results based on the selected task and will only display samples that have an associated DT_GEO_TEST table record where TEST_TYPE = ‘Sieve’ and ‘Hydrometer’ when the TEST_METHOD = ‘ASTM D422’, ‘ASTM C136’, or is null.

Excel Name Manager Field	EQuIS Source	Description
