Final answer:
The optimal time to call inspectors for maximum efficiency is at specific project milestones or inspections. This allows for a systematic and organized approach to ensuring quality and compliance, preventing costly rework or delays.
Step-by-step explanation:
The optimal time to call inspectors for maximum efficiency is d. At specific project milestones or inspections. Calling inspectors at specific project milestones or inspections allows for a systematic and organized approach to ensuring quality and compliance. By involving inspectors at these crucial points in a project, any potential issues or defects can be identified and addressed early on, preventing costly rework or delays. For example, in construction projects, inspectors may be called at milestones like the completion of the foundation, framing, electrical, and plumbing work. This ensures that each aspect of the project meets the required standards before moving on to the next phase.
