Competent Person (CP) Duties

CPs must develop the Excavation and Trenching Plan and Activity Hazard Analysis (AHA).
They must conduct documented inspections of excavations to manage potential hazards and stop work if deemed unsafe, promptly correcting any identified risks.
They must perform soil classification testing, examine protective system materials for damage, and monitor water control operations to ensure safety.

Qualified Person (QP) Responsibilities

QPs are responsible for designing Class 1 perimeter protection and ramps for equipment access into excavations to prevent falls and facilitate safe entry.

Registered Professional Engineer (RPE) Responsibilities

RPEs must evaluate and ensure the safety of adjacent structures before excavation and plan any necessary control measures such as drainage.
They are also tasked with designing support systems and sloping or benching for deep excavations.
