CSLB C-33 Painting & DecoratingPlanning and EstimatingMedium
A painting contractor is bidding on a large commercial repaint project. The project involves extensive surface preparation, including power washing, scraping loose paint, and patching numerous hairline cracks. The project manager estimates that these prep tasks will require 250 person-hours. The crew consists of three painters, and the project is scheduled for 10 working days, 8 hours per day. What is the estimated labor cost for surface preparation if the average hourly wage for a painter, including benefits and burden, is $45?
- A$13,500
- B$33,750
- C$12,000
- D$11,250
Show answer & explanationAnswer & explanation
Correct answer: D. $11,250
The labor cost for surface preparation is calculated by multiplying the total estimated person-hours by the average hourly wage. In this case, 250 person-hours * $45/hour = $11,250.
Why the other options are wrong
- A. This would be the cost if the total person-hours were 300, or the hourly rate was $54.
- B. This is an overestimation, possibly from multiplying by the number of painters or days incorrectly.
- C. This might result from an incorrect calculation or misinterpretation of total hours or rate.
