Final answer:
Inspections for deterioration or leaks should be routine and frequent, based on materials and environmental conditions, to maintain structural safety and integrity.
Step-by-step explanation:
The frequency of inspections for deterioration or leaks should be determined based on the materials involved and the environmental conditions to which the structures are exposed. As a benchmark, significant deterioration has been known to develop around 18 years after construction completion, highlighting the importance of routine checks to ensure structural integrity.
Furthermore, incidents such as corrosion leading to catastrophic events like the collapse of the Silver Bridge should be a sobering reminder of the need for regular maintenance and inspection of structures. Factors such as changes in load, environmental stressors, and wear and tear can all accelerate deterioration, making it essential to inspect structures for leaks and degradation on a regular basis, with intervals suggested by engineering guidelines and safety standards. In the context of residential buildings, strategies to mitigate air infiltration can also provide insights into the frequency of inspection required for maintaining optimal conditions and preventing unintended leaks due to compromised weather stripping, caulking, or window seals.
