Determine the cost to lay the CMU block in Problem 9. It takes 5.5 mason labor hours and 7.5 laborer labor hours to construct 100 square feet of wall. The average wage rate for the masons is $39.74 per labor hour and the average wage rate for laborers is $22.35 per labor hour. From Problem 9, the area of the fence is 1,667 sf or 16.67 sq.

What will be an ideal response?


Mason labor hours = 16.67 sq × 5.5 lhr per sq = 91.7 lhr

Mason labor cost = 91.7 lhr × $39.74/lhr = $3,644

Laborer labor hours = 16.67 sq × 7.5 lhr per sq = 125 lhr

Laborer labor cost = 125 lhr × $22.35/lhr = $2,794

Total labor cost = $3,644 + $2,794 = $6,438
