Construction methods can be split into two major families whatever material is used (concrete, steel, etc.):
Today, these structures call on a wide variety of construction methods:
-carriage form travellers and self-launching trusses for in-situ construction,
-launching gantries for cantilever installation,
-staying masts for progressive installation,
-assembly trusses for full-span construction,
-launching, lifting and rotation systems for moving structures into position.
All of these accessories and materials are designed, studied, supplied and implemented by Freyssinet.
