Final answer:
Licensed structural or professional engineers are the ones qualified to design and plan lift-slab operations due to their expertise in structural engineering, understanding of materials, and knowledge of safety standards and building codes.
Step-by-step explanation:
Lift-slab operations should be designed and planned by professionals who have specific expertise in structural engineering, such as a licensed structural engineer or a professional engineer. These individuals will have a comprehensive understanding of the forces and stresses involved, the properties of construction materials, and the relevant safety standards and building codes to ensure a safe and effective design. Their planning ensures that all safety measures are considered, such as the preparation of a pre-construction plan, which involves detailed schematics and calculations.
