CSLB C-33 Painting & DecoratingPlanning and EstimatingMedium
A painting contractor is preparing an estimate for a large exterior commercial building. The project requires the use of a 60-foot boom lift for access to high areas. The rental cost for the boom lift is $800 per day, and the project is expected to require the lift for 15 working days. The contractor also needs to account for the cost of a certified operator at $60 per hour for 8 hours a day, for the same 15 days. What is the total estimated equipment and operator cost for the boom lift for this project?
- A$19,200
- B$12,000
- C$7,200
- D$26,400
Show answer & explanationAnswer & explanation
Correct answer: A. $19,200
First, calculate the total rental cost: $800/day * 15 days = $12,000. Next, calculate the total operator cost: $60/hour * 8 hours/day * 15 days = $7,200. Finally, add these two costs together: $12,000 + $7,200 = $19,200.
Why the other options are wrong
- B. This only accounts for the rental cost of the boom lift, not the operator.
- C. This only accounts for the operator cost, not the boom lift rental.
- D. This is an overestimation, possibly due to a calculation error in one of the components.
Equipment and Operator Cost
The combined expense for renting or owning specialized equipment and the labor cost of the personnel required to operate that equipment for a project.
- Includes rental/depreciation of equipment.
- Encompasses wages, benefits, and burden for operators.
- Must be accurately estimated for projects requiring specialized machinery.
Memory trick: Rental Rates + Riding Rates = Real Riches.
