Detailed analysis and control of the construction process of the Constitución de 1812 Bridge over the Cadiz Bay

The erection of the bridge with an almost symmetrical balanced cantilever, with a maximum length of 218.5m, with no additional supports apart from the tower itself, and the erection of the truly massive segment of about 20.0m long, 34.30m wide, and up to 4,000kN in weight, establishing the construction sequence when part of the towers were already erected, have made the calculation and control of the construction a significant challenge.It has required a detailed analysis of the 1275 construction stages using non-linear geometric and material calculations, checking all the cable stays, tower and deck elements, including accidental actions, such as fallen segments, exhaustively controlling all loads on the deck and changes in the construction sequence.
