A 2 x 4 sill plate runs around the floor in Figure 14.61. Determine the takeoff of 2 x 12's needed for the floor framing and sum it all up into a total linear feet of 2 x 12's required. For example, ten - 2 x 12's at 12' would be 120 linear feet. -DOUBLE 2x12 UNDER WALL 4x6 POST -DOUBLE 2x12 UNDER WALL DOUBLE 2x12- -17- 2x12 @ 16 O.C.- 3@2x12 DOUBLE 2x12 HEADER 40' FIGURE 14.61.

(6) Determine the square feet of waterproofing needed for a rectangular basement 26 feet by 40 feet. The waterproofing is 8 feet high. How many gallons of waterproofing are needed if one gallon of waterproofing will cover 60 square feet? 9. (8) Determine the square feet of waterproofing needed for the basement shown in Figures 15.12 and 15.13. The waterproofing starts 6 inches from the top of the wall and continues to the top outside corner of the footing. How many gallons of waterproofing are needed if one gallon of waterproofing will cover 65 square feet? 25 21' FIGURE 15.12. Foundation Plan. 2'-6" 36 8 0 0 10' 20 10. How many squares of roofing and how many pieces of ridge shingles are needed for the roof in Figure 15.19? The slope of the roof is an 8:12 and the exposure is 5 inches wide. Note the building walls are 24' x 30' and the roof extends over by 2' on each side and has a projection on the ground of 28' x 34! You must account for the slope of the roof to determine the area and squares of shingles. 2x6 24 OC 1x8 RIDGE -2x6 @ 24 OC 30' 34 FIGURE 15.19.

On numeric problems you need to show all you work and reference any tables you use. Short answer questions need to be complete answers and not just a few words. I find that word documents transmit best, or scanned documents are also acceptable. Turing in work early is great but late work is penalized. I recommend that you not wait until the last minute to submit and if you are having problems please let me know via email.
