Determine the interior areas to be painted for the Real Estate Office in Appendix E. Using the labor rates from Problem 7-31 and the crew rate for the finish crew from Problem 7-32 determine the cost to paint the office.

Question

What will be an ideal response?

Answer 1

The following data can be extracted from the model:



All of the 24?? × 48?? windows are in the exterior walls. Only 2 of the 36?? × 72?? windows are in the exterior walls. The 20 of the 36?? × 84?? doors are in the interior walls. The other doors are in the exterior walls.



Length of walls = 241? + 2 × 463? = 1,167?



The walls are 9?1?? high, but the acoustical ceiling is at 8? – Paint to 8.5?



Gross area of wall = 1,167? × 8.5? = 9,920 sf



Deduct for doors = 1 ea × 3? × 7? + 2 sides × 20 ea × 3? × 7? + 1 ea × 6? × 7?



Deduct for doors = 903 sf



Deduct for windows = 34 ea × 2? × 4? + 2 sides × 12 ea × 3? × 6? + 2 ea × 3? × 6?



Deduct for windows = 740 sf



Deduct area of ceramic tile. From problem 34, the perimeter of the rooms with tile is 60?3??.



Length = 60?3?? – 3 ea × 3 ? = 51?3??



Area of tile = 51?3?? × 4? = 205 sf



Net area of wall = 9,920 sf – 903 sf – 740 sf – 205 sf = 8,072 sf



The ceiling does not need to be painted because it is hid by a dropped acoustical ceiling, except for in the restrooms and janitor closet. From Problem 34 the areas of these ceilings is 76 square feet.



Twenty 3? × 7? doors need to be painted. Each door has 26? of trim for a total of 520?.
