The following figures are used for the test questions for this chapter:

Figure 1: Floor Framing Plan

Figure 2: Floor Plan

Figure 3: Roof Plan

Figure 4: Roof Plan

Figure 5: Cabinet Elevation

1) The perimeter of the floor system in Figure 1 sits on a redwood sill. Determine the number of 16 - foot - long pieces of redwood that are needed to complete the floor system.

2) Determine the materials needed to complete the posts and girder supporting the floor joists in Figure 1. The posts are connected to footings using a Simpson® PB46 post base and are connected to the girder using a Simpson® BC46 post cap. The distance between the top of the footing and the bottom of the girder is seven feet. The posts are equally spaced along the glue - laminated beam.

3) Determine the materials needed to construct the joists and joist headers for the floor system shown in Figure 1. An engineered rim board is used for the joist headers.

4) For the floor system shown in Figure 1, the joists are blocked over the girder and at the midpoint between the girder and the exterior wall on the joists over eight feet long. I - joists are to be used for the blocking. How many feet of I - joists are needed for the blocking?

5) Determine the number of 4 - foot by 8 - foot sheets of 23/32 T&G OSB sheathing that are needed to construct the floor system shown in Figure 1.

6) How many board feet of 2 × 4 redwood decking are needed to construct a 40 - foot by 20 - foot deck? The boards are to be placed with a 1/2 inch space between the boards.

7) How many board feet of 2 × 4 treated and untreated plate is needed to construct 150 feet of 2 × 4 wall? The wall bears on a concrete floor.

8) How many board feet of 2 × 4 treated and untreated plate is needed to construct 85 feet of 2 × 4 wall? The wall bears on a wood floor.

9) How many studs are needed to construct 210 feet of 2 × 4 wall? The wall has two 8 - foot - wide windows, three 4 - foot - wide windows, four 36 - inch - wide doors, two 30 - inch - wide doors, eight corners, four intersections, and four hold downs located at corners. The stud spacing is 16 inches on center. Allow for two additional studs for each corner, intersection, or doorway; six additional studs for each window less than six feet in width; eight additional studs for each window six feet or more in width; and one additional stud for each hold down located at a corner.

10) Prepare a materials list for the headers required to complete a wall with two 8 - foot - wide windows, three 4 - foot - wide windows, four 36 - inch - wide doors, and two 30 - inch - wide doors. All headers are made from 2 × 12 materials with OSB spacer and the wall is made from 2 × 4s. Openings six feet or more in width require double jack studs.

11) How many 4 - foot by 8 - foot sheets of 7/16 inch OSB are needed to construct 85 feet of wall 9 feet 3 inches high?

12) How many feet of treated and untreated plate are needed to construct the walls shown in Figure 2? The walls are constructed of 2 × 4s with the exterior walls being sheathed with 7/16 inch OSB. The wall bears on a concrete floor.

13) How many studs are needed to frame the wall in Figure 2? The stud spacing is sixteen inches on center. Allow for one additional stud for each wall that does not have a corner; two additional studs for each corner, intersection, or doorway; six additional studs for each window less than six feet in width; and eight additional studs for each window six feet or more in width.

14) Prepare a materials list for the headers required to complete the walls in Figure 2. All headers are made from 2 × 12s with OSB spacer and the wall is made from 2 × 4s. The exterior doors are 36 inches wide, the interior single - hung doors are 32 inches wide, and the bifold doors are 6 feet wide. Openings six feet or more in width require double jack studs.

15) How many lineal feet of blocking is needed for the walls in Figure 2 if the studs in the exterior walls are blocked at their midpoints.

16) How many 4 - foot by 8 - foot sheets of 7/16 - inch OSB are needed to sheet the outside of the exterior walls shown in Figure 2 if the wall height is nine feet?

17) A roof framed with 2 × 8 rafters has a span of 36 feet, an overhang of 18 inches, and a slope of 5:12. What length of common rafters needs to be ordered for the roof?

18) The hip roof shown in Figure 3 is constructed of 2 × 10 rafters spaced 16 inches on center. The hip rafters are 1 1/2 - inch - wide by 12 - inch - high GLBs. The roof has a slope of 4:12. Prepare a list of lengths and quantities for the 2 × 10s and GLBs. Ceiling joists will be used to prevent the walls from spreading. Do not include the ceiling joists in your estimate.

19) How much waterproofing is needed to cover the foundation walls in Figure 1? The foundation wall is 8 feet high and sits on a footing that is 12 inches high and the footing extends 8 inches beyond the foundation wall on the exterior side. Assume that the waterproofing starts 6 inches below the top of the foundation wall and covers the top surface of the footings.

20) Determine the number of rolls of fifteen - pound asphalt - impregnated felt needed for the roof in Figure 2. The felt is to be lapped 6 inches on the side and 12 inches on the ends. The felt is available in rolls 3 feet wide with 4 squares (400 square feet) per roll. The slope on the roof is 5:12.
