In groining without ribs, the centering of timber extended during construction under the whole surface. 2. In ribbed or groined work, the centering for the stone ribs, which need support until their arches are closed, after which the supports for the filling of the spandrils are sustained by the ribs themselves. (Harris, 1977)
