What does the abbreviation "W" typically refer to on a set of plans?

The abbreviation "W" on a set of plans typically stands for "Window." This designation is essential in construction documentation as it helps clarify the locations, sizes, and types of windows required in the building. Accurate identification of windows is crucial since they impact not only the aesthetics of the structure but also factors such as energy efficiency, natural light entry, and ventilation.

Understanding the symbolism used in architectural plans enhances communication among the project team, ensuring that builders, architects, and clients share a common understanding of the design. While the other options might also be found in plans, "W" is conventionally recognized to designate windows in most architectural contexts.
