Explanation:
The crew works 3 × 8 = 24 crew-hours. Production rate = 1,200 ÷ 24 = 50 square feet per crew-hour.
Question
3
When comparing supplier quotations before bid day, which practice best reduces the risk of a scope gap?
Explanation:
Quote leveling compares each proposal against the same scope and documents so missing items, exclusions, freight, and alternates can be identified before selecting a price.
Question
4
What is the primary purpose of acknowledging issued addenda in a bid?
Explanation:
Acknowledging addenda shows that revisions issued during bidding were received and considered in the bid.
Question
5
Direct project cost is $420,000. The estimator adds 8% for company overhead and then 5% profit on the subtotal. What is the resulting bid amount before taxes or bonds?
Explanation:
Overhead = $420,000 × 0.08 = $33,600, giving $453,600. Profit = $453,600 × 0.05 = $22,680. Total = $476,280.
