Where is the correct rigging configuration found?

• A. Manufacturer's manual
• B. Project schedule
• C. Shop drawings provided by the erector
• D. City permit

Answer: (C)

Rigging configuration for lifting tilt‑up panels is defined in the shop drawings prepared by the erector. These drawings translate the actual panel geometry, center of gravity, weight, crane access, and attachment points into a field-ready plan that specifies exact lift points, sling angles, hardware, load paths, sequencing, and any temporary bracing. They are the project document that guides the crew on how the lift will be executed safely and efficiently, and they are reviewed and approved to ensure they reflect the engineered requirements.

General manufacturer manuals offer broad guidance but not a project-specific rigging setup. The project schedule focuses on timing and sequencing of tasks, not the technical rigging details. City permits address code compliance and approvals, not the precise lift configuration used in this project.
