What is one duty of the special inspector before an observation?

One key responsibility of a special inspector before an observation is to record the frequency of inspection. This duty is essential as it helps maintain a comprehensive log of the inspections conducted throughout a project. Keeping accurate records of inspection frequency ensures compliance with regulatory requirements and project specifications. It allows for monitoring the adherence to proper construction practices over time and helps identify any trends or recurring issues that may need addressing.

While other choices might involve important aspects of project management or communication, they do not specifically pertain to the unique role of the special inspector in terms of monitoring and documenting inspection activities. Knowing the frequency of inspections is crucial for both the inspector's accountability and the overall integrity of the project.
