Cast in situ
Balanced-cantilever bridge construction
Segments cast in place from each pier in balanced pairs, using form travellers that
carry their formwork below or above the deck and launch themselves forward.
Overhead and underslung configurations for different segment lengths and weights
Cast in situ
Span-by-span cast-in-place construction
Whole spans of concrete superstructure formed and cast between the permanent piers,
without falsework from the ground, on continuous and simply supported bridges.
Spans 20–70 m
Precast
Precast segmental bridge erection
Precast segments and beams lifted and placed span by span or by balanced cantilever,
by self-launching gantries, launchers and lifters working off the completed deck.
Launching gantries for span erection and curved alignments, with segment lifters for units from 100–900 t
