Template Methodology

The primary unit for the design of templates within Template Studio is the meter, regardless of the final output units of the log. A borehole log is composed of several parts that are dynamically assembled to generate the final output. The main component is the "Master Template", which defines page size and margins, as well as containing the static header and footer sections of the borehole logs.

The middle section consists of vertical columns of depth-related information, which make up the bulk of the borehole log. An individual column (or group of sub-columns) is referred to as a “Strip”. When grouped together for a given report style, these columns are referred to collectively as a "Strip Set". A Master Template can have multiple Strip Sets available to it. Strip Sets are groups of individual strips arranged in a specific order and may also have strips with visibility conditions that will only be displayed if those conditions are met (for example, if PID readings are present).

Naming Convention

All of the default Template Studio parts are named according to a standard convention, regardless of region. The naming convention is as follows:

Item Type - Description - Region - Version (if required)

For example, "Master Template - Default Letter - US" indicates that this is the default letter-size template for the North American Metric configuration pack, and "Strip - Description - UK" indicates the individual strip piece that contains the Description column in the UK configuration pack.

This naming convention is used for all out-of-the-box Template Studio parts, making it easy to identify the type, purpose, and region of each part. If a version number is included in the name, it indicates that the part has been updated from an earlier version

Geological Descriptions

OpenGround offers both component-based and non-component-based methods for building geological descriptions of soil and rock. In a component-based approach, each parameter, such as colour, is saved individually in the database. These components are then assembled to create a generic description that can be modified to suit your needs.

The non-component-based description is essentially a free-form method of entering descriptions, allowing for faster entry at the trade-off of standardization and potential variations across users. Additionally, there is the ability to use “Quick Lists” to provide prompts on ordering and typical descriptors used for things like consistency or moisture value.

OpenGround will by default generate a description based on any values in the Component-Based Section, however, if there is a Non-Component Description present it will use that instead to populate the Description field.

SPT Testing and N-Values

The way that Standard Penetration Test (SPT) results are summarized on a log output can vary between organizations. With the default settings in OpenGround, SPT results are summarized in the following way:

• OpenGround has four SPT intervals, with a penetration of 150 mm per interval. Users can enter up to four intervals, depending on regional and organizational standards.
• The N-value, if applicable, is calculated based on intervals 2 and 3.
• Data entry accounts for tests with four blow count intervals, refusal depths, weight of rod (WOR) penetration, or weight of hammer (WOH) penetration. Data entry profiles are available for both desktop and field data entry (using Collector).
• Blow count fields are integer values only. WOH and WOR are entered in separate picklist fields. For WOH or WOR to appear in the blow count results, zero must be entered in the associated blow count field, as well as WOH or WOR in the associated picklist field.
• Refusal penetration for any interval is calculated by OpenGround based on the Penetration Total field.

The table below shows some typical data entry occurrences and how they are reported on a log output:

 

Field Test Scenario	Grid View	Reported Results on Log
3 intervals, full penetration (450 mm)
4 intervals, full penetration (600 mm)
WOH/WOR in any interval, full penetration
Refusal, any penetration < 450 mm
Refusal, 4th penetration interval > 450 mm and <600 mm

Note that the way SPT results are summarized on a log output can be customized according to the specific needs of your organization. These default settings are provided as a starting point, but they can be changed as needed.
