Determine the cost to lay the CMU block in Problem 13. It takes 6 mason labor hours and 8.5 laborer labor hours to construct 100 square feet of wall. The average wage rate for the masons is $42.33 per labor hour and the average wage rate for laborers is $21.03 per labor hour.

What will be an ideal response?


From Problem 13, the area of the wall is 907 sf or 9.07 sq.

Mason labor hours = 9.07 sq × 6.0 lhr per sq = 54.4 lhr

Mason labor cost = 54.4 lhr × $42.33/lhr = $2,303

Laborer labor hours = 9.07 sq × 8.5 lhr per sq = 77.1lhr

Laborer labor cost = 77.1 lhr × $21.03/lhr = $1,621

Total labor cost = $2,303 + $1,621 = $3,924
