centering, the framework of wood or of wood and steel built to support a masonry arch or vault during its construction. The centering itself must be rigidly supported, either by posts from the ground or by trusses when piers are available to receive their ends. After the centering is built, the setting of the masonry proceeds equally from the ends or sides toward the central point, where the keystone of the arch or the crowning blocks of the vault are finally wedged into position. The centering is removed after setting in the case of arches where the shape is dependent on the cement or concrete, but in other instances, e.g., where dressed stone is used with a lime mortar joint, it is better to remove the centering before setting, so that gravity will control the disposition of the stones.
