Two different procedures of construction are introduced: the traditional sequence and the new sequence. The traditional sequence consists in a first casting phase that is formed by the lower slab and webs and a second casting phase that is formed by the top slab of the deck. Once the first and second casting phases are completed, the total prestressing force is introduced. The new sequence consists in a self-supporting core that is formed by the lower slab, webs and top slab cantilevers and a second casting phase that is formed by the central zone of the top slab. Once the self-supporting core is completed, a partial prestressing force is introduced so that the scaffolding can advance to the next span. Both sequences are described with their constructive peculiarities and issues related to the constructive easiness and cost reductions.
