05/08/2016 - Shows difference in height. The concrete foundations shown in the diagram are a key part of the method of launching caissons at Lepe. The foundations shown (1 of 8) are the points at which the weight of the caisson is transferred from a continuous rail (the production line) to the launch slipway. In order for the caisson to clear these concrete foundations on its way down the slipway they are built lower than the adjacent foundations by about half a metre.
