Determine materials required to frame the roof 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 roof.
The following data can be extracted from the model:
From page S1.2 the following trusses can be counted:
Two Simpson H1 ties are required for each standard and hip truss (one at each end where they bear on the walls). One Simpson H1 is requires of the single-pitch trusses (one end bears on the wall and the other attaches to a hip truss.
H1 = 2 x (11 + 24) + 48 = 118 ea
Order two 2 × 6 @ 8 feet long for the hips in the corners and two 2 × 4 @ 8 feet long for the lookouts in the corners.
Determine the sheathing for the roof from the model:
Manually determine the sheathing:
Length = 1?8?? + 72? + 1?8?? = 75?4??
Length = 1?8?? + 50? + 1?8?? = 53?4??
Area of sheathing = 75?4?? × 53?4?? × 1.12 = 4,499 sf – the difference is due to rounding of the 1.12
2 × 6 shaped fascia = 75?4?? + 53?4?? + 75?4?? + 53?4?? = 257?4?? – Use 258?
2 × 4 sill = 72? + 50? + 72? + 50? = 244?
A 1?5?? backing is needed for every single-pitch truss and two are needed for the standard and hip trusses:
Backing = 11 × 2 + 24 × 2 + 48 = 118 ea
Five can be cut from an 8-foot-long board. Order 24 2 × 4 @ 8 foot long
