An alternative to concrete for the upper reduced crosssection is to construct a brick pier off the mass concrete pad (see Fig. 9.15). This solution has the advantage of avoiding the need for expensive shuttering and can result in an overall saving. If brickwork is adopted it is necessary that the pad size provides the necessary working space for the bricklayers to build the pier.
