LESSON 2 ANSWERS TO SELF TEST EXERCISES
1. The construction working drawing presents a complete graphic description of the structure to be erected, the
construction site, the materials to be used, and the construction method to be followed. (para 2-1,a)
2. Detail drawings comprise sections and detail views; general drawings consist of plans and elevations. (para 2-
1,a)
3. Figure A-1 of the appendix contains typical architectural symbols and shows (a) as a double door, opening out;
(b) as a double door, interior; (c) as a double window, opening out; and (d) as a single window, opening in.
(para 2-2,a) (fig A-1, app A)
4. Using figure 2-2, which shows various material conventions, it can be seen that (a) represents concrete, (b)
represents cut stone, (c) represents gravel, and (d) represents regular stone. (para 2-2,b) (fig 2-2)
5. From Schedule of Facilities: (fig 2-3) No. 4 is recreation building, No. 5 is athletic courts. Using arrow
pointing north it can be seen that the easternmost athletic court is the one on the right.
(a) overall width of plot is 490 feet
(b) distance from western boundary to centerline of roadway is 125 feet
(c) distance from centerline of roadway to east side of recreation building is 60 feet + 120 feet = 180 feet
(d) distance from eastern boundary to west side of athletic court is 25 feet + 60 feet 85 feet
(e) adding b, c, and d: 125 feet + 180 feet + 85 feet = 390 feet
(f) subtracting e from a: 490 feet - 390 feet = 100 feet (para 2-2, a,b) (fig 2-3)
6. The surface elevation slopes downward toward the northwest corner; therefore, the water tank (No. 7) rests on
the highest ground level, which is approximately 325 feet. (para 2-3,a,b) (fig 2-3)
7. On an elevation drawing, the centerline symbol is used to indicate finished floor lines. (para 2-4,b)
8. On a plan view, the symbol next to a stairway will indicate the direction of the stairs from the floor shown in
the plan and the number of risers in the run. The symbol 18DN would mean that the number of risers in the
run of stairs is 18. (para 2-5,b)
9. All items listed except the location of openings in foundation walls would be shown on detail drawings and
not a foundation plan. (para 2-9)
10. The correct representation for lumber which has been surfaced on three sides and one edge would be S3S1E,
(para 2-6,c(1)(b))
11. The balloon frame is less rigid than a braced or western frame but represents a savings in material and labor.
(para 2-7,b)
