Use The Patterns To Do Building Diagnostic Work

Oncc the patterns have been learned and understood, they can become a powerful basis for figuring out the causes of various building failures. Problems in real buildings make the most effective vehicles for these exercises. As practice exercises and problems for classroom discussion, you can invent such situations as the following:

1. Narrow, parallel bands of dampness occur at 2' (600 mm) spacings on the ceiling of a single-story industrial steel frame building in the winter. What is the likely cause? Can you draw a detail that represents the probable existing condition that causes the problem? Can you modify this detail to eliminate the problem?

2. A brick facing is buckling on a six-story classroom building. . ..

4. People in the waiting room can hear conversations between a psychiatrist and her patients. . . .

5. The plaster immediately beneath a window stool becomes damp after a prolonged wind-driven rainstorm. . . .

6. During renovation work, carpenters discover that the insulation in a ten-year-old wood frame wall is sat urated with moisture and the framing is beginning to decay. . . .

8. An outdoor deck floored with pine 6 X 2s traps puddles of water during rainstorms. . . .

9. The flashings in a masonry chimney are corroding. . . .
