BUILDING THE ROYAL SOVEREIGN LIGHT TOWER
Tide Mills beach c1970
By Celia Malfroot
These show when a storm broke through and flooded the building site. The site was dug and then kept dry by pumps 24/7. The fear was that too much water around the caisson could lift it up. The long vertical rods are "Macalloy bars" made of EN8 steel, this is/was con rod steel. From the base these bars were extended to the top of the caisson and to the top of the tower each bar having 70 tons of load put upon them. This holds it all together. Christiani & Nielsen were the builder, at the time the largest privately owned construction company.
