Abstract:
The vision for Spencer Dock Bridge in Dublin, Ireland, was to create a fluid, free-formed shape that satisfied the constraints of providing a navigational channel beneath the eastern end of the deck while accommodating the light rail track form within the depth of the structure. The geometry of the bridge deck soffit and parapets is such that the shape could only be achieved by casting concrete on expanded polystyrene (EPS) formwork. A discussion of the concrete finish for the bridge deck, in terms of the concrete profile, uniformity, and consistency of surface appearance, is provided. The concrete mixture comprised 70% slag cement replacement.
