Who is responsible for performing tests and collecting samples?

The responsibility of performing tests and collecting samples typically falls under the jurisdiction of various specialized roles. While project personnel can certainly be involved in the process of sampling, the most accurate responsibilities in a construction or earthwork context align with roles specifically dedicated to quality assurance.

Laboratory technicians, for instance, are often responsible for the actual testing of samples collected from the field, ensuring that materials meet the necessary specifications. Quality control inspectors monitor the entire process and ensure compliance with standards, contributing to the overall assurance of project quality.

However, project personnel often play a more general role that encompasses a wide range of duties, including coordination and oversight. While they may be involved in the initial collection of samples under some circumstances, the specific responsibility for testing and quality-related tasks is more appropriately assigned to the specialized roles. Thus, selecting project personnel as the sole responsible party for these tasks may not accurately reflect the designated roles within a construction project.
