  The objective of this study is to determine the types of existing buildings
that are at risk of falling debris based on height, age, construction
classification, construction methods and materials and occupancy. This study
focuses on elements that could become debris under high wind action and present
a hazard to pedestrians, vehicles, and nearby structures. This study evaluated
the particular building elements that might become Wind Generated Debris (WGD).
This was accomplished by inspecting 500 buildings located in Manhattan that
experienced wind-related incidents. The results illustrate that the building
elements most likely to produce WGD are windows, followed by exterior fixtures,
roof elements, stairs/sidewalk shed, and balcony elements, respectively.
Consequently, FISP inspectors should pay particular attention to these
elements, which have higher probabilities in causing incidents.
