Which of the following is an example of building problems with poor construction methods?

• A. Basement or roof leakage
• B. Moisture condensation on windows
• C. Overheating due to poor workmanship
• D. Poor daylighting

Answer: (A)

Water intrusion is a direct result of how the building envelope is put together. When waterproofing, flashing, slope, and drainage around foundations and roofs aren’t installed correctly or become compromised, water can seep in through cracks or joints, leading to basement or roof leaks. This clearly reflects a problem with construction methods, since the basic barrier against moisture wasn’t built or finished properly.

Moisture condensation on windows, while related to humidity and ventilation, stems more from indoor moisture levels and glazing performance than from a specific construction defect. Overheating due to poor workmanship can happen if insulation or air sealing is inadequate, but leaks are the most straightforward indicator of construction-related failure in the building envelope. Poor daylighting is typically tied to design choices, not a construction method issue.
