1 Choose the right sampling method

When planning a project, you need to consider the objectives, site characteristics, and budget when selecting a sampling method for soil and rock. Disturbed sampling is one of the most common methods and involves collecting loose or disturbed soil samples with tools like augers, shovels, or scoops. This method is useful for identifying soil types, moisture content, and organic matter; however, it cannot provide accurate information on strength, density, or permeability. Undisturbed sampling is another common method that involves extracting intact or undisturbed soil samples with tools such as thin-walled tubes, Shelby tubes, or piston samplers. This method is useful for testing the engineering properties of soil; however, it requires more care and equipment to obtain and preserve. Finally, rock coring is a more expensive and time-consuming method that involves drilling and retrieving cylindrical rock cores with diamond or tungsten carbide bits. This method is useful for examining the structure, composition, and quality of rock as well as performing strength and durability tests.

When planning a project, choose the sampling method based on objectives, site characteristics, and budget. Disturbed sampling with tools like augers or shovels is good for identifying soil types and moisture but lacks accuracy for strength or density. Undisturbed sampling with tools like Shelby tubes provides data on soil engineering properties but requires more care and equipment. Rock coring, using diamond or tungsten carbide bits, is expensive and time-consuming but essential for detailed rock analysis.

Another thing that would inform the sampling technique and even the scope of said technique is information about the geology and topography of the area involved that can be obtained during desk study.

Las mejores prácticas para el muestreo de suelos y rocas durante las investigaciones del sitio incluyen una planificación meticulosa y el uso de técnicas adecuadas. Primero, desarrolle un plan de muestreo detallado que considere la heterogeneidad del sitio y los objetivos del proyecto. Utilice equipos de perforación y muestreo apropiados, como barrenas y perforadoras, para obtener muestras representativas. Asegúrese de que las muestras sean extraídas a diferentes profundidades y ubicaciones para capturar la variabilidad del terreno. Mantenga la integridad de las muestras mediante un manejo cuidadoso y un almacenamiento adecuado en contenedores sellados. Documente meticulosamente la ubicación, profundidad y condiciones de cada muestra.

2 Follow the relevant standards and guidelines

When performing soil and rock sampling, it is important to follow the relevant standards and guidelines for your industry and location. These could include international, national, or regional codes of practice, specifications, or regulations that define the procedures, equipment, and quality criteria for sampling. For instance, some of the commonly used standards and guidelines are ASTM D420, BS EN ISO 22475-1, AS 1726, and NZS 4402. Adhering to these standards and guidelines will guarantee that your soil and rock samples are consistent, comparable, and compliant with the expectations of your customers, regulators, and stakeholders.

3 Label and document your samples properly

One of the most important aspects of soil and rock sampling is to label and document your samples properly. This will help you avoid confusion, errors, or disputes later on. You should label each sample with a unique identifier that includes the project name, site location, borehole number, depth, and date. You should also document the sampling method, equipment, and conditions in a field logbook or report. Additionally, you should take photos or videos of your samples and the site to provide visual evidence and context.

4 Preserve and transport your samples carefully

Preserving and transporting your soil and rock samples correctly is essential to maintain their integrity and quality until they reach the laboratory. Depending on the type and purpose of the sample, as well as the expected duration and mode of transportation, you should use different preservation methods. These include sealing, refrigeration, freezing, and stabilization. Additionally, you should transport your samples securely, avoiding shocks, vibrations, or temperature fluctuations. Appropriate containers, packaging, and labels should be used to protect and identify your samples during transportation. Finally, you should keep a record of the chain of custody and delivery of your samples to the laboratory.

5 Verify and validate your samples regularly

The final best practice for soil and rock sampling is to verify and validate your samples regularly. You can do this by performing field tests at the site, such as density, moisture, or classification tests, to check their properties and consistency. Additionally, laboratory tests can be conducted to validate their engineering performance and behavior. Quality control is also essential, which involves comparing your samples and test results with the expected values, standards, or benchmarks, and correcting any errors, anomalies, or deviations. By verifying and validating your samples regularly, you can guarantee that your soil and rock sampling gives accurate and helpful data for your site investigations and construction projects.

Ensuring the accuracy of soil and rock samples is essential for effective site investigations and construction projects. To achieve this, regular verification and validation procedures are indispensable. Field tests, including density, moisture, or classification tests, are conducted on-site to assess sample properties and consistency. Laboratory tests further validate the engineering performance and behavior of the samples. Quality control plays a vital role in this process. It entails comparing sample and test results with expected values, standards, or benchmarks to identify any discrepancies. Any errors, anomalies, or deviations are rectified promptly to maintain data integrity.
