When performing a labor unit analysis for electrical estimating, what does the term 'labor unit' represent?
Answer: The number of man-hours required to install one unit of material
A labor unit is the number of man-hours required to install one unit of a specific material under normal conditions.
Which scheduling technique uses a probabilistic approach by defining optimistic, most likely, and pessimistic durations for each activity?
Answer: Program Evaluation and Review Technique (PERT)
PERT uses three-point duration estimates (optimistic, most likely, pessimistic) to account for schedule uncertainty.
In electrical project management, what is the primary purpose of a Schedule of Values?
Answer: To allocate the total contract value across work items for progress billing
A Schedule of Values breaks down the contract sum by work items so progress payments can be accurately calculated and billed.
What does a 'productivity factor' of 0.85 indicate on an electrical project?
Answer: Workers are operating at 85% of the standard labor unit efficiency
A productivity factor of 0.85 means the crew is performing at 85% of the standard published labor unit, requiring more hours than baseline.
Which of the following is considered an indirect cost in electrical contracting?
Answer: Project superintendent's salary
Indirect costs like superintendent salaries are not directly tied to specific installed items but support overall project execution.
When calculating a bid, an electrical contractor adds overhead and profit after determining the bare cost. If bare cost is $400,000, overhead is 15%, and profit is 10%, what is the total bid?
Answer: $506,000
Overhead: $400,000 × 1.15 = $460,000; then profit: $460,000 × 1.10 = $506,000.
In project scheduling, 'float' or 'slack' refers to which of the following?
Answer: The amount of time an activity can be delayed without delaying the project completion
Float is the amount of time a non-critical activity can be delayed without affecting the overall project completion date.
