What might trigger a special inspection during construction?

Changes to the approved plans or unforeseen site conditions can trigger a special inspection during construction because they indicate modifications that could impact the safety, compliance, or structural integrity of the project. When plans are altered or unexpected conditions arise, these scenarios necessitate a closer examination to ensure that the project still adheres to all applicable codes and standards.

Special inspections are designed to address significant issues that might not be captured during routine inspections. Thus, if changes are made that differ from what was originally approved, or if conditions on site present new challenges that weren't accounted for, a special inspection becomes essential to assess risk and verify that the construction quality meets established requirements. This process helps ensure that any adjustments are properly evaluated and documented, maintaining the integrity of the construction project.

While other options might involve aspects of monitoring and project management, they do not carry the same level of urgency or potential impact on compliance as the changes mentioned in the correct response.
