Principles

The main idea of the Book A phasis is to collect factual data and express their content. In the Book A, we will find all the documents produced in the past on the studied area (geological maps, collection of geologists, etc.). Generally, it is necessary to complete these elements with specific investigations.

Acts

Geotechnical engineers and team can perform several acts in order to better understand the environment:

• Observations
• Geotech Procedures (codelist)
• Geotech Observable Properties (codelist)
• Sampling and Preparation

Proxies

O&M activities are applied on features of interest that act as proxies.

This includes:

• Borehole
• TrialPit

Some proxies can be collected on the field, to be studied elsewhere (eg. in a laboratory), they are called:

• MaterialSample

Note: A borehole core is considered as a MaterialSample.

FAQ

What do O&M include?

All kind of observation, measurements that can be performed.

This include:

• Geological observations,
• Geotech in-situ tests,
• Geotech laboratory tests,
• Environmental analysis,
• Geophysics.

Why focusing on acts and not just providing results?

The proposed conceptual model follows the principles of ISO 19156 for Observations, Measurements and Samples.

In geotechnics and in many other domains results must be contextualized and can only be used in a specific context.

Acts of observation, measurement or sampling provide this context and the necessary metadata to enable the use and reuse of the data.
