Bowen Bridge
A notable example of modern caisson work is to be found in the Bowen Bridge at Hobart designed by Maunsell and Partners. Here, in 1982, massive gravity caissons were constructed to a maximum depth of 40 metres (inside 14 metre diameter precast concrete cofferdams). In recognition of the vital significance of a permanent crossing of the River Derwent, these caissons were designed to resist head-on collision by a 5000 tonne ship.Finally, recent technological advances have led to the development of instrumentation of driven piles which permits accurate assessment of resistance and soil properties during driving from records of strain and acceleration. This scientific enhancement to the practice of pile design and construction meets a long felt need, and could well represent one of the great steps out of the Roman Age of foundation engineering.
