Which of the following is an example of supplier preassembly that can reduce field labor costs on an electrical job?

When an electrical contractor utilizes supplier preassembly, such as ordering fixtures that are already pre-whipped and pre-lamped, the estimator should expect a reduction in both material costs and field labor costs.

As an estimator or project manager reviewing site inefficiencies, match each labor-wasting field scenario with the specific supplier preassembly or packaging choice that would best resolve it based on the concept of labor-reduction.

An estimator is evaluating supplier preassembly for a commercial lighting project. Standard boxed fixtures cost $8,000 in materials and require 100 hours of field labor to assemble and install. Pre-whipped and palletized fixtures cost $9,500 in materials but reduce the field labor to 60 hours. If the company's burdened labor rate is $50 per hour, choosing the pre-assembled option will result in a net overall cost savings of ____ dollars.

You are an estimator preparing a bid for a large commercial lighting project with 500 fixtures. You want to determine whether ordering pre-assembled options (such as fixtures that arrive with wiring connections and lamps already installed, or fixtures shipped on pallets instead of in individual boxes) will produce a net cost savings compared to buying standard unassembled materials. Arrange the following decision steps in the most logical and effective order for making this evaluation.
