Cost estimating
Step 2: Find the cost of the crew per hour = (1x60) + (3x30) = $150. Step 3: Find the number of hours required for the crew to work = 114/30 = 3.8 day 8 hours in a day 3.8days x 8hr/days = 30.4 hrs = I always round up in estimates to 31 hrs. Step 4: Total cost for the personnel: = 31 hours x $150 / hours = $4650 Problem 2: A contractor need to ...
