The incremental launching method is one of the highly mechanised erection methods used in bridge construction. The method consists of manufacturing the superstructure of a bridge by sections in a prefabrication area behind one of the abutments; each new unit is concreted directly against the preceding one and after it has hardened the resultant structure is moved forward by the length of one unit.


Incremental Launching Method scheme

During the construction stage the superstructure is centrally prestressed, to limit the tensile stresses produced by the bending moments. The skilful use of prestressing is the most important of this construction sequence.
