1-A building requires a 100-foot long by 83-foot wide by 5-inchthick concrete slab. Using a waste factor of 10 %, Includecalculations. a)determine the number of cubic yards of concreteneeded to pour the slab. (2 points)
2-Determine the number of rolls of wire mesh needed if there are750 SF of wire per roll and 12% of waste. Include calculations. (2points) 9 BCT 2770 Estimating Fundamentals
3-Determine the amount of rebar needed for the slab if it isreinforced with #4 rebar at 12 inches on center both ways. Assume 2inches of cover and add 10% for lap and waste. Includecalculations.(11 points) Tip=Use the density method
4-Determine the cost to finish the slab using a productivity of0.011 labor hours per SF and an average labor rate of $29.92 perlabor hour. Include calculations.(2 points)
5-A vapor barrier is to be placed below the slab. Determine thenumber of 10-foot by 100-foot rolls of vapor barrier needed. Thevapor barrier needs to be lapped one foot. Hint: Subtract the lapfrom the width of the roll. Include calculations. (2 points)
