We establish some structural results for the Witt and Grothendieck–Witt groups of schemes over Z[1/2] , including homotopy invariance for Witt groups and a formula for the Witt and Grothendieck–Witt groups of punctured affine spaces over a scheme. All these results hold for singular schemes and at the level of spectra.
