1-A building requires a 100-foot long by 83-foot wide by 5-inch thick concrete slab. Using a waste factor of 10 %, Include calculations. a)determine the number of cubic yards of concrete needed to pour the slab. 

2-Determine the number of rolls of wire mesh needed if there are 750 SF of wire per roll and 12% of waste. Include calculations. (2 points) 9 BCT 2770 Estimating Fundamentals

3-Determine the amount of rebar needed for the slab if it is reinforced with #4 rebar at 12 inches on center both ways. Assume 2 inches of cover and add 10% for lap and waste. Include calculations.(11 points) Tip=Use the density method

4-Determine the cost to finish the slab using a productivity of 0.011 labor hours per SF and an average labor rate of $29.92 per labor hour. Include calculations.(2 points)

5-A vapor barrier is to be placed below the slab. Determine the number of 10-foot by 100-foot rolls of vapor barrier needed. The vapor barrier needs to be lapped one foot. Hint: Subtract the lap from the width of the roll. Include calculations.
