Louisiana Contractor License Exam

Under OSHA construction standards, at what height above a lower level does fall protection generally become required for workers on a construction site?

1. A2 feet
2. B4 feet
3. C6 feetCorrect
4. D20 feet

Why: OSHA's construction fall-protection rule (29 CFR 1926.501) generally requires protection — such as guardrails, safety nets, or personal fall-arrest systems — when a worker is exposed to a fall of 6 feet or more to a lower level. (Note the general-industry trigger is 4 feet, but on construction sites the 6-foot rule applies.) Falls are consistently a leading cause of construction fatalities, which is why this threshold is heavily tested and enforced.

A contractor's total direct cost for a job is $18,000. The contractor adds a 15% markup to cover overhead and profit. What is the bid price?

1. A$18,150
2. B$18,270
3. C$20,700Correct
4. D$21,150

Why: Markup is a percentage added on top of cost. Multiply the cost by (1 + markup): $18,000 x 1.15 = $20,700. The markup dollars are $18,000 x 0.15 = $2,700, which is added to the $18,000 cost to reach the bid price. Markup covers both company overhead and profit.
