In this note we show that every Kirchberg algebra in the UCT class is the$C^{\ast}$-algebra of a Hausdorff, ample, amenable and locally contractinggroupoid. The non-unital case follows from Spielberg's graph-based models forKirchberg algebras. Our contribution is the unital case and our proof builds onSpielberg's construction.

All classifiable Kirchberg algebras are $C^{\ast}$-algebras of ample groupoids
