Where can sample, sample size, and sample frequency be found?

The correct answer indicates that the details regarding sample, sample size, and sample frequency can be found in both JGS (Job Guidance Specifications) and STRG (Standard Testing and Reporting Guidelines).

These documents are essential in defining the standards for sampling in earthworks, ensuring that project specifications are met consistently. JGS typically outlines specific requirements for various job types, including how sampling should be conducted and the appropriate number of samples required for various conditions. STRG often contains methodologies related to testing procedures and the frequency of sampling necessary to maintain quality control during the project.

It's vital for a qualified individual to consult these resources because they provide the critical framework needed for accurate data collection and testing in the field, thus supporting the overall integrity of the earthwork process. Understanding these specifications is crucial for successful project compliance and quality assurance.
