12. REDMAN, J. B., 5 Terrace, New Palace Yard, Westminster — Designer.
Model of the royal terrace pier at Milton-on-Thames, next Gravesend, designed by the exhibitor, and made by Salter of Hammersmith. The pier is constructed of iron by Fox and Henderson. The pillars are founded upon piers of brickwork and masonry below the bed of the river, resting upon the solid chalk substratum, at a level of 14 feet below low water of spring tides. These foundation piers were erected without the expensive aid of cofferdams, by the novel means of cast-iron cylinders six feet in diameter, kept always above the rise of the tide, the upper portions being removed as each pier was finished.
