Question: A carpenter is calculating the cost for installing 120 square metres of hardwood flooring. The material cost is $45.00 per square metre. Labour is estimated at 0.5 hours per square metre at a rate of $60.00 per hour. If a 15% contingency is added to the total direct cost, what is the estimated total cost for the flooring installation?
Answer options:
- $8,100.00
- $9,000.00
- $10,350.00 ✅ $11,902.50
Correct answer: $11,902.50
Explanation: Material cost: 120 m² * $45.00/m² = $5,400.00. Labour cost: 120 m² * 0.5 hr/m² * $60.00/hr = $3,600.00. Total direct cost = $5,400.00 + $3,600.00 = $9,000.00. With a 15% contingency, the total estimated cost is $9,000.00 * 1.15 = $10,350.00. So the correct answer is $10,350.00.
