Which type of load would include the weight of unexpected renovations?

The type of load that would encompass the weight of unexpected renovations is referred to as an undesigned load. This term captures any additional loads not originally accounted for during the design phase of a structure, such as weight from renovations or modifications that were not part of the initial design specifications.

In the context of structural engineering and building design, understanding the difference between various load types is crucial. Design loads are the loads the structure is designed to support, while dead loads refer specifically to the permanent static loads, like the weight of the building materials themselves. Impact loads are transient forces applied suddenly to a structure, such as those from vehicles or seismic activity. Since unexpected renovations introduce additional loads without prior consideration in the original design, they accurately fall under the category of undesigned loads. This concept emphasizes the need for flexibility and consideration of additional factors that may impact the integrity of a structure after its initial construction.
