An accident at St. Katherine's dock led to the top half of this cast lamppost falling off. It hit the bottom half of the bollard, breaking it as shown in these pictures. 

We attended the location and excavated the bollard, so we could repair it at our workshop. The main structural collar of the bollard was damaged beyond repair, so it couldn't be welded back on. Instead, we created a new top and mechanically fixed it to the bollard. We then added small decorative parts to fill the larger holes.
