Which of the following can cause a structure to be shored and braced before demolition?

In the context of preparing a structure for demolition, it is essential to ensure that the building is stable and safe before work begins. Shoring and bracing are techniques used to support a structure that has become compromised due to various conditions.

Wind damage can weaken the structural integrity of a building, particularly if portions of the structure are leaning or if there are exposed elements. If a building has sustained significant wind damage, shoring may be necessary to prevent further collapse during demolition.

Flooding can lead to water damage, which can compromise the load-bearing components of a structure. For example, prolonged exposure to water can weaken wooden supports or lead to deterioration of masonry. Consequently, shoring might be necessary to stabilize the building before demolition takes place.

Fire can severely damage the structural elements of a building, weakening beams and walls. If a structure has been affected by fire, it may not be safe to assume that it can stand on its own. Shoring and bracing would be used to ensure safety during the demolition process.

Considering all these factors, each of these scenarios can contribute to the decision to shore and brace a building before demolition, which is why the response indicates that all of these conditions can necessitate such precautions.
