Transport Infrastructures

Ranging from major construction projects to the rehabilitation of pedestrian, road and rail bridges to overpasses, automated people mover and underground transit systems, ADF Group has developed extensive expertise in this field, both at the connection engineering level and fabrication processes and handling methods in the plant and installation of heavy steel components and complex steel structures. In fact, the environment in which these steel structures are erected is more demanding due to road restrictions, urban constraints or the location of the sites.

ADF was awarded the contract for the engineering, fabrication and installation of the steel structure of a new passenger pier for the Royal Caribbean Cruise Lines, at the Port of San Juan.

The structure, two huge triangular pylons, made of large cylindrical steel tubes – some having over three feet (1 m) in diameter – linked together by smaller steel tubes placed at different angles, were assembled on-site in three sections, and installed using a crane on a barge.

Once the special cable system was installed, the steel structure supported a canvas awning the entire pier, and protecting cruise passengers. The complete structure has a total length of 182 feet (55.5 m), with its highest point standing 94 feet (29 m) above ground.
