We equip the category of vector bundles over the vertices of a locally finite \(\tilde{A}_{n-1}\) building \(\Delta \) with the structure of a module category over a category of type \(A_{n}\) webs in positive characteristic. This module category is a q-analogue of the \(Rep(SL_{n})\) action on vector bundles over the \(sl_n\) weight lattice. We show our module categories are equivariant with respect to symmetries of the building, and when a group G acts simply transitively on the vertices of \(\Delta \) this recovers the fiber functors constructed by C. Jones.
