Who Are Structural Movers?

There is no dictionary definition for a structural mover. So, who are they? A structural mover is an individual or company that moves structures. While this may sound rather simple, successfully moving large, cumbersome, heavy, small, weird shaped structures of various types is anything but simple. Lighthouses, hotels, movie theatres, airport terminals, barges, ships, bridges, grain elevators, houses, libraries, transformers, draglines, and viaducts are some examples of the type structures moved. Moves such as these occur daily across North America and around the globe. In fact, relocating structures is the worlds oldest and largest recycling industry. The services provided by structural movers create and save jobs, preserve historic structures, prevent wasteful demolition, reduce material to landfills, provide increased opportunities for affordable housing and a multitude of additional benefits. Just like the type of structures moved, structural movers also come in various sizes, operations, specialties, methods and opinions on how moves should be made. It is no secret that structural movers as individuals tend to think things through carefully, and are adept at mathematics and geometry.
