What does "Technically Infeasible" refer to in the context of alterations?

"Technically Infeasible" refers to a situation where a modification or alteration cannot be accomplished due to existing structural conditions. This term indicates that no matter the intent or desire to make a change, the underlying infrastructure, layout, or physical constraints of the building or system simply do not allow for that change to be executed without significant complications or impossibility. This might include scenarios where there are structural elements that prevent modifications, such as load-bearing walls, existing ductwork, or other critical systems that cannot be altered.

Understanding this concept is crucial for professionals in the plumbing and construction industries, as it affects decision-making regarding design and implementation of systems. In contrast, the other options describe scenarios that either relate to minor changes that don't impact the overall structure or issues related to cost rather than physical limitations.
