Determine materials required to frame the walls for the Real Estate Office in Appendix E. Using the labor rates from Problem 7-31 and the crew rate for the rough carpentry crew from Problem 7-32 determine the cost to frame the walls.
What will be an ideal response?
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.
Determine the materials needed for the exterior walls. There are 241? of exterior walls. Run the sill plate through the doors for ease of construction. 241 feet of treated plate is needed for the sill.
The top plates will require twice the above quantities or 482? or 322 bf.
Weathermate = 241'/50 ft per roll = 5 rolls
Determine the number of studs needed:
Wall studs = 241? × 0.75 spaces per foot = 181 – Use 182 studs
Studs for doors/windows = (34 + 2 + 1 + 1) × 2 = 76 studs
Studs for corners = 4 × 2 = 8 studs
Studs for intersections = 15 × 2 = 30 studs
Total studs = 182 studs + 76 studs + 8 studs + 30 studs = 296 studs
The header materials are as follows:
The sheathing is calculated as follows: Ignore the door and window openings because this material will be waste.
Area of exterior walls = 9?1? × 241? = 2,189 sf
Tyvek comes in 9 ft x 150 ft rolls
Tyvek = 241' / 150 ft per roll = 2 rolls
Determine the materials needed for the interior walls. There are 463? of interior walls. Run the sill plate through the doors for ease of construction. 463 feet of treated plate is needed for the sill.
The top plates will require twice the above quantities or 926? or 618 bf.
Determine the number of studs needed:
Wall studs = 463? × 0.75 spaces per foot = 348 – Use 349 studs
Studs for doors/windows = (12 + 20) × 2 = 64 studs
Studs for corners = 10 × 2 = 20 studs
Studs for intersections = 19 × 2 = 38 studs
Total studs = 349 studs + 64 studs + 20 studs + 38 studs = 471 studs
The header materials are as follows:
