The ceiling of the residence shown in Figure 16.18 is plastered with 3/8 of an inch of plaster over metal lath. Determine the number of cubic feet of plaster needed for the ceiling.
What will be an ideal response?
From Problem 17, the area of the ceiling is 886 sf.
Area of ceiling = 886 sf / 9 sf per sy = 99 sy
From Table 16-7 of Estimating Building Construction, 5.2 cf of plaster is needed per 1/16? thickness plus 8.0 cf for the metal lath.
Plaster per hundred sy = 5.2 cf per 1/16? × 6 + 8.0 = 39.2 cf per hundred sy
Plaster = 0.99 hundred sy × 39.2 cf per hundred sy = 38.8 cf
