Some airport terminals require a lot of judgment to determine what to include in the silhouette. Typically, I want to include the main structure of the building to represent the shape of the terminal, which means I normally exclude things like sunshades and jet bridges unless they are significant to the structure.
In the case of YVR, a lot of the jet bridges are not directly anchored to the terminal building; instead, they’re attached to the end of solid fingers that extend from the main structure. Ultimately, I decided to include those fingers, since they are permanent, immobile, and for the most part actually part of the building. (I did decide to exclude the jet bridges themselves, and the round stairs attached to many of the fingers.)
However, I also think the fingers clutter up the terminal silhouette quite a lot, and are a blemish on what I consider an otherwise beautiful silhouette.
