Final answer:
The statement is false because even with unit pricing, a take-off is still necessary to determine the exact quantities of items needed for a project, ensuring accurate procurement and cost estimation.
Step-by-step explanation:
The statement that the biggest advantage when using unit pricing is that you do not need to complete a take-off to determine the number of luminaries, switches, receptacles, and so forth is false.
Unit pricing is a method of cost calculation where a fixed price is assigned to a single unit of an item, which can make budgeting and cost comparison easier.
However, a take-off, which is the process of calculating the exact materials and quantities needed for a project, is still essential in determining the number of items such as luminaries, switches, and receptacles required for a project. This ensures accuracy in both the procurement of materials and overall project cost estimation.
