Which items should be included in the site inspection prior to erection?

• A. Only weather forecast
• B. Panel color and texture
• C. Terrain and levelness, access, underground hazards, power lines, and lifting equipment
• D. Crane model and paint

Answer: (C)

Before tilting up, inspect conditions that directly affect safe lifting and placement of panels. Terrain and levelness matter because the ground and slab edges must be firm and even to support crane outriggers, avoid sinking, and ensure precise panel seating. If the surface is soft, uneven, or poorly compacted, it can destabilize the crane and lead to misalignment or a collapse.

Access is essential so that panels, cranes, trucks, and other equipment can move in and out without delays or hazards. Clear routes, adequate space for maneuvering, and unobstructed paths to the erection area prevent pinch points, dropped loads, and traffic conflicts.

Underground hazards must be identified to avoid striking buried utilities like gas lines, water mains, or electrical cables. Locating and marking these before any digging or setup prevents fires, explosions, or electrocution and helps plan safe work zones.

Power lines overhead require careful planning and coordination. Maintaining safe clearances, using a dedicated spotter, and coordinating with the utility company reduce the risk of contact with live lines during lifts.

Lifting equipment should be assessed to ensure the crane or hoisting system is appropriate for the panel weight and reach, properly inspected, and set up with proper rigging and ground support. Verifying equipment capacity, condition, outrigger setup, and lifting plans minimizes the danger of equipment failure or unstable lifts.

Weather and other choices might influence scheduling but don’t by themselves establish a safe, workable erection plan. Panel color and texture relate to finish, not site-safety readiness. A crane model and its paint status don’t address the full safety and suitability checks needed for a successful lift.

That’s why this comprehensive set of items is the best choice for a pre-erection site inspection.
